Got RAM questions...

Bought a nice 1600 kit for my RIVE, since at the time benching was what old ladies did in parks while feeding the pigeons.

Since,.... discovered this murky underworld of tweaks and tertiary timings etc and am looking for a new RAM kit to have some fun with. 8 Pack once told me to look for PSC or some such; which I noded at as it went straight over my head.

What would be a good quad kit 16GB for X79 for benching 2133 or 2400. I was looking at the new platinums and CMD16GX3M4A2400C9 in particular but seems only dual channel on corsair website though I see people running it ok on X79?

Any advice?

Go dual channel for SuperPI(if you plan on benching this a lot), that's what HiVizMan told me. And yep, you're quite right...at the moment the Plats are only Dual Channel, which is rather surprising.

Arne Saknussemm
11-05-2012, 12:07 PM
Yeah I saw the dual channel boards are cleaning up Pi and I have come to a bit of a wall in what I can do in that comp with my RAM I think....still experimenting....:D

But I see those platinums sold everywhere in 4 stick kits :confused:

You will be surprised as to what ram works well and that it is actually quite cheap.

If you want killer overclocking ram for the RIVE platform, get some Samsung green.

Samsung Green 8GB (2x4GB) DDR3 PC3-12800C11 1600MHz 30nm Dual Channel Kit MV-3V4G3D/US

You will pay under £50 for that kit, and you are most likely (CPU IMC dependant) going to get 2600MHz with little effort.

Not going to be too tight for Super PI but no-one makes PCS or BBSE any more. And BBSE and PSC are the good memory to get for benching on SB or IB. So go for frequency :)



Overclocking Features (Not Guaranteed)- 1600MHz (7-8-8-24 1N) @ 1.40v
- 1866MHz (9-9-9-27 1N) @ 1.40v
- 2000MHz (9-10-10-28 1N) @ 1.45v
- 2133MHz (10-10-10-28 1N) @ 1.45v
- 2400MHz (11-11-11-28 2N) @ 1.50v
- In our own in house testing we were able to achieve all the above clock speeds on an Asus X79 platform with 4x4GB modules (16GB total) SuperPI Stable too, 32M

I think that quad channel is only meaning matched dual channel kit... and it's up the CPU/IMC if it's running it in quad or dual channel... - so, if you have a quad channel capable CPU, then a matched 4 sticks dual channel RAM will run as quad channel with no probs...

I have a Dominator Platinum kit, which on the Corsair site is dual channel... got it from Newegg, where the exactly same kit was quad channel... I was thinking, if it doesn't works, just will send them back to Newegg - but it was no trouble until now... (everything is showing the RAMs as quad channel)

I have looked high and low for some PCS, been looking in every forum that has hardware for sell to find used and have seen none, the people that have it hold onto it. I have 2 sets of 2x2 gb of the Samsung Green Viz is referring to and the Platinum that Zoltan has, plus a GSkill 4x2GB Z series 4X2, thinking that 4 sticks of 2gb may overclock better that a 16gb kit which is becoming the norm. Th Platinum dual channel comes packaged in a quad kit and works excellent. I am building my stock of ram the best I can to experiment with, my favorite for everyday use on the RIVE has been the Dominator GT 2133 16gb kit at 1.5 volts, the more I play with memory the more I realize I don't know anything. It is very time consuming with small gains or losses for the trouble on X79.

Arne Saknussemm
11-05-2012, 02:41 PM
Thanks! All three of you! Clears up some posibilities...especially if that's two of you with Platinum that works quad channel. And with nice timings too if it works with my IMC...and they look nice hehe

HiVizMan thanks for the timings and the suggestion...don't know if I want to just go for MHz OCing...more interested in tight timings and the efficiency idea....

Hmmmm....:rolleyes:

HiVizMan
11-05-2012, 03:29 PM
No stress Arne the thing is you will find that with different memory straps frequency in benching makes as much difference as tight latency. But as a rule of thumb tighter latency is better for 2D stuff for sure.

And I have a couple of PSC kits :)

Arne Saknussemm
11-05-2012, 05:35 PM
Hey HiVizMan..OK I might not have understood exactly what you were trying to say. Let me see if this is right at the same frequency tighter timings better but also even if I divide latency by frequency and get the same number the higher frequency RAM is better?? Or even if that division produces close numbers maybe the higher frequency is still better?

And can I ask what is a PSC kit what does that mean? Why are they good... why unavailable if so (Except to your good self of course hehehe)

HiVizMan
11-05-2012, 05:48 PM
They are no longer made. What happens is that the ram chips we use or vendors use for the ram kits we buy are all made by two or three factories. Some of those kits were made two or three years ago. Some of the chip manufactures have shut down. So what we are left with is a supply chain that basically goes via GSkill currently. That is why they are the top dog of ram. I bought my kits, second hand or from small retailers that had "dead" stock that they were just pleased to get rid off. But what you will not hear about normally is the 20 odd kits that were rubbish, just to find one or two that are good. :D

The frequency thing is not that easy to work out as a simple equation. It is all about the IMC and the design of the processor. So for example with Ivy some of the time Cas 8 has been quicker than Cas 7 (we are talking serious frequency here, not 1600MHz.) And sometime tight latency can negatively impact on performance. Not all benchmarks want 32Mil levels of tight latency. Actually none do. Each benchmark has its own optimal ram settings. And often that effort, the unseen research that goes on after hours is what separates the great benchers from the merely good.

Bottom line - look on ebay, second hand threads on forums or simply do the best with what is available. :)

........ simply do the best with what is available. :)

I'm sure of that!! A bad workman always blames his tools! I used to go ice climbing with bits of sawn off pipe as a poor student in places that folk with the latest greatest ice screws never got to so I'm not coming at this from the wrong direction I hope. I'm not trying to buy improvement in a kit just would like to get something that has the potential in it if I do the searching for it. I've done quite a bit of tweaking with my current kit but seem to have come to a wall in finding improvements with it and see most are using higher frequency kits so was wondering what way to jump. But I don't have the time to go through 20 second hand PSC kits lol:)

We are all in the same boat Arne, buy the time you see some threads on some special kit it to late, at least the price of dram has never been lower 10 years ago or less you would spend more on dram than on your motherboard and cpu combined.

Arne Saknussemm
11-06-2012, 09:49 AM
Boat? wish I was in a boat....feel like I'm in a leaky canoe as far as RAM goes...but I'll get there....lol.

Have you played much with your platinum kit....tried tightening timings much etc?

8 Pack
11-06-2012, 10:53 AM
As Hiviz points out tight timings are the way to go with 2D benches in almost all situations but not sacrificing tight timings for RAW CPU speed as IMC is under more stress with tighter timings. 32mil is slightly different as RAM timings can make up for some CPU speed. You have to balance off what is good in your situation.

I have four GSKILL PSC sticks for X79 benching 2D 32mb I use these settings.

http://www.hwbot.org/submission/2291871_8_pack_superpi_32m_core_i7_3930k_6min_7sec _47ms

For 3D using X79 ie Vantage and 11. I use GSKILL Ripzaws Hynix at these settings.

http://www.hwbot.org/submission/2325515_8_pack_3dmark_vantage___performance_geforc e_gtx_680_52285_marks

It really does depend on the system and the bench you need to test different IC's and settings mate and work out whats best for your situation.

If you do decide to ever bench Z77 also both PSC and Hynix work well on that platform too!!

Arne Saknussemm
11-06-2012, 11:27 AM
Hey 8 Pack a mine of useful info as always and thanks for putting it up there. I have a ton to learn on this stuff. For HiVizMan's challenge my clocks have actually been relatively low so been concentrating for timings. i can see that going for all out speed I'll have to do as you say ballance brute CPU speed with timings even relaxing them possibly. As always no recipe each CPU/system is it's own world but it's a great help to have pointers!!Cheers man:D

EDIT: How do you know it's PSC or Hynix etc. are you taking off heat spreaders and looking at chips etc.?

8 Pack
11-06-2012, 11:46 AM
I have taken spreaders off in the past yes. Mainly to find Eliphida kit that will scale well on the cold with high volts.

But not on these kits just search around the forums for other users. Also each RAM IC in the main is given away in its stock timings. PSC for example is usually 2gb dimms and sloppes up and down at stock timings so 6-7-6 or 7-8-7 or 8-9-8. Hynix on the other hand goes sharpely up and down and is 4gb dimms. So 9-11-10 or 10-12-11. Samsung generally has up then flat timings in 4gb dimms so 9-10-10 or 10-11-11.

As long as you can bail the water out faster then it leaks in your doing good.
Unfortunately I haven't had time to play much lately, been busy at work, doctors appointments and my 18 year old son, but I have been watching these forums and socking up the knowledge from everyone in the challenge and the tips from the masters, Viz, 8 pack, Raja, can;t thank these guys enough for being so generous with their knowledge, Hope the next challenge is 3D.

Hey dudes....advice....I've found these in Australia... http://www.gskill.com/products.php?index=251

These in Europe: http://www.gskill.com/products.php?index=260

which is going to be better on X79.....6 gb tri channel at cas 6 1600mhz or 4 GB at cas 7 2133mhz.....

Zka17
03-16-2013, 03:40 PM
I have the 2x2GB Pi kit, 2133MHz CL7... - it works nice on the RIVE! :)

The 2133MHz CL7 should be faster than the 1600MHz CL6... - but don't know about the tri-channel thing on the RIVE... maybe just use dual channel?

Chino

Yeah I guess for PI the 2133 cas 7 is a simple choice but for other stuff.....is it any use for other benches and if so maybe 6gb and another channel is better....:confused:

8 Pack
03-19-2013, 02:35 PM
When I bench I use 4 x 2133mhz CL7 GSKILL PSC stuff on RIVE. For 3D it goes 8-12-9-28 1T at 2500 plus on RIVE.

Interestingly for LN2 on RAM I am using the 4gb (2 x2gb) CL6 kit 1600mhz Pi stuff on Z77. Just working on a C6 2600+ tuned profile for HWbot pro cup 32mb, so far at 2600 6-11-7-25 1T TRFC at 74 with LB at 1.

If your using this 24/7 I would go with the C7 2133 and just enable XMP, mode 2 and your ready to go. Then tune bench. If its for bench then either may well do a similar job.

Wow, again just wow, you've got a 1600MHz kit to work at 2400MHz without needing to change the timings?! Well, you've changed from CL6 to CL7, but just that?

As I said previously somewhere else, I would like to see some screenshots of your results with CPU-Z opened at the CPU, RAM and mobo tabs...

What voltage are you using for the RAM?

Also, you must have a very good CPU...

Thx guys, and yep all i done is load tight psc profile and put 1.8v through them, 8Pack tells me upto 1.85v will be fine, but i'm not that brave yet! In the process of stripping my loop down so i can install my 3930, so once i'm up and running, lots of testing/benches/pictures etc. i shall open my own thread up as got lots of things to try.

Well I think I got lucky tonight, last week I found a 2x2 gb set of 2300 pi 8-11-8-24, just stuck it on the RIVE and set the tight psc timings left default 1.65 volts set it to 2400mhz, and booted right up no problem, plan on playing some this weekend, but tonight I found 6 sticks of 1600mhz pi 6-8-6-20 1.6 volt ram on ebay for sale not bid, so I snapped it up, figure i will take the chance, whats the worst that could happen, nicklp1974 this pic looks mysteriously similar to yours? Not complaining

I have never been very successful at tweaking memory, always just bought ram with a higher speed rating than system was rated for so it would run without issues, think I will try my hand, I am not a patient person though.

I had bought a set of 2x2gb 1600 7-8-7-24 1.5volt a long time ago I thought I had lost as I have been looking for it for a while, just found it in my closet with some other stuff so I stuck it in the RIVE with the 2300 kit, set it at 2133 8-11-8-24 1.65volts just to see if it would boot, and no problem running Vantage at that setting, I really am no good at tweaking ram, either my M/B, IMC, or both must be ok as I have not found any ram that would not run at least at XMP ratings, even Corsair Vengence, which was the only quad kit I could find when I originally purchased the RIVE. In my usual stupid method I will just turn up the juice and see how far they'll clock

I have been selling a few items recently so while I was there I was stalking the memory section, after i get this kit of six where I can install 4 on my RIVE I may give up some although when I just started my pc i went to bios and did nothing but changed setting from 2133 to 2400 and booted like it was made to run at that, this is with 2 mismatched kits. I should have spent the time to search for these kits before, I am very curious now at what speed they can reach on the x79

Luumi
04-26-2013, 03:10 AM
Wow Menthol, how much did you pay for the 2300 Pis? I have been looking for them aswell, but they either don't exist or they cost way too much.


Just FYI if anyone is looking for very cheap ram that can do 2400 speeds, I saw this kit from Crucial hitting 2400 mhz with 9-9-9 timings and with only 1.65v. They cost like 15 euros for a stick here.

And then Hivizman said: "Time to face up to the fact your CPU IMC is not that good. " Ah, interesting :) .
20620

The funny thing is to find out your IMC would love to go over 2700, but then your ram stops you from going higher as usual :/ .

Luumi
05-14-2013, 11:25 PM
Holy mother of god: http://valid.canardpc.com/show_oc.php?id=2803479

Close to IMC limits here. I really would like to just see 2700, but I need to push cpu temps higher to achieve it since x79 IMCs are very picky to low temperature. I know some of you may think what is the point of trying to reach highest ram speed ss, but I find it fun to test the maximums of your hardware :P .

Menthol
05-15-2013, 12:37 AM
No we understand, breaking your personal barriers, topping the best you have been able to achieve previously, and now I will have to try higher than I achieved last time, the reward = self satisfaction

Luumi
05-15-2013, 01:14 AM
Exactly Menthol. TIme to push your Pis and see what you can get. I saw that kit (2300 cl8) for sale in Finland for 50 euros some time ago, I should have bought them while they were dusty and forgotten in the store.

Menthol
05-15-2013, 02:03 AM
lol yes you should have, I am surprised I got to 2500 now I'll shoot for 2600, just to see if I can get there. what voltage did it take you to get that speed, I was on 1.8 to get to 2400 with tight psc timings in bios, bumped it to 1.85v and 2500, seemed stable, probably have to leave voltage and loosen timings to go higher

Luumi
05-15-2013, 02:41 AM
I used raw mhz profile, 1.78v dram and 0.88 ddrvtt. I loaded into windows at 2666 and kept increasing bclk from oc key with clockgen reset disabled and validating using F7 key until I crashed.

Vtt was 1.26v and vccsa 1.27v. I really wouldn't feel comfortable with over 1.85v dram voltage on 2011 platform without extreme cooling. Try loosening the timings or even raw mhz profile if you want to test their max mhz potential or your IMC.

Menthol
05-15-2013, 01:12 PM
I am impressed at your achievements, I keep getting reminded how little I really know

Luumi
05-16-2013, 10:03 PM
Menthol I really recommend you should try the old 0006b bios. I have tried lots of different bioses with my new ram kits and that one is definetely the best one. You can find it here: http://www.mediafire.com/?33a9inzdym9n523

I have crazy stability with this bios, much better than on all the others I have tested so far with these patriots.
My 24/7 settings for now with HT of course:
20709

Just rename it to ERALL.rom and it should work, you can still have a modern cap bios in the second bios chip, so you can switch between them if you like.

Menthol

Well that's crazy I have 2 kits of 2x2gb 2400 sector 5 coming soon, not sure of the part number but it is 9-11-9-27 psc modules, just couldn't resist when I seen it.
I recently installed a 3970X processor only supported since bios 2015 I think, may have to put the 3930k back in when I get some time and flash back to the older bios, I will be watching your results closely. I don't have any extreme cooling so limited to water, still it's all good times

What I have experienced with the sectors on RIVE is that without 006b bios I always had to use command rate 3 to remain stable. That is why you need to dig your 3930k again and put the old bios on your board.

Here i was about to post my luck with 2133 unstable 32GB of samsung green ram and then you guys start bragging about your Pi rams.
Now with the ek SF3D LN2 ram pots I been looking at buying.$212 for 2 after shipping but 150 for flask and 300-500 for dewar and i still have no clue how expensive the actual liquid nitrogen is

You can still find many cheap ram kits with PSC or elpida bbse chips if you google around and pay attention to your local super pc stores and ebay. That is how we have got ours. I looked for rare memory modules for months and finally found 3 dominator gt 7.1A 2000 8-9-8 sticks for 50 euros and 2x 2500 patriot sector 5 and 2x 2400 sector 5 sticks for 100 euros so take your time looking around.

Yes it takes patience and determination to find these older high quality kits.
I haven't done any testing but it took 3 boots to get to these timings at 1.7 volts, back on 3930k with 4004 bios, I am finding that it will take a lot of time and endless testing to find best ram settings, I am very intimidated by the number of timing options on newer boards and have no clue where to start. I guess first get them stable and then after the first set of timings?????? Oh ya 4 sticks of the Patriot Sector 5

The key with memory tuning is to know what your outcome is.

The first 4 timings and the command rate will be pretty much set in stone after 5 mins of working with your ram. The determining factor is voltage and temperature assuming that the CPU IMC is not holding you back.

So if you are tuning for Super Pi 32 mil then you have a starting place. Now focus on your secondary timings. This process will also take a very short amount of time as there is just so much you can do with them. In other words optimal settings have all been worked out previously. The memory presets in the RIVE bios for example are very good as a starting point. All the gains and tweaking is now found in the tertiary settings.


If you are tuning for some other benchmark then you just have to understand what the benchmark wants. AM3 for example wants bandwidth, so make sure your settings provide heaps of bandwidth and do not worry to much about ultra tight timings.

Luumi
05-21-2013, 06:43 PM
Menthol try Tight PSC preset, put 9-11-9-28 1T at 2500. Although change second timings like mine (ofc you can try what you wish, just my guideline with same memories) tRRD 5 tRFC 124 tWR 10-14 tRTP 5 tFAW 24 tWTR 5 TWCL 8.

You may notice that getting those sticks to run with command rate 1 can be quite hard.

Menthol
05-22-2013, 01:48 AM
I am sure you are correct, as soon as I get some time I will test them with your settings, work has been taking so much time lately and have to find a new place to live and move soon. I have a stack of memory to test but these sticks will be #1 on the list, I will copy all your timings in a list for later use and let you know how it goes.
Thanks very mush for sharing your results with me

Menthol
05-22-2013, 04:06 AM
You are correct,
I could not get 2500 at 1t, 2t, or 3t, could not get 2666 with RAW settings, at least on bios 4004, I think the IMC was a little better on the 3970 then my 3930, can't test that as I don't have that chip anymore, this was just a quick trial to be continued at a later time and the other bios, just don't like IROG version updating switching between bios versions. I do use this same pc for everyday usage, at the least I may learn some about memory tweaking and 2D benching as those are my weakest areas. Thanks very much for all the tips

Luumi
05-22-2013, 01:09 PM
I use 0006 bios for everyday use :P, and yes the iROG updating screen always comes if you switch between the bios chips. If you can't get 2500 to work at all then it could be your IMC holding you back.

Arne Saknussemm
05-23-2013, 08:46 PM
Are there any "rules" to these timing tweaks? I mean, I can slap in what I want and try it but is there some art to this? Like if I chose CAS 6 should tFAW be... cas 6 times square root of frequency divided by channel number to the power of tRAS.... do you know what I mean? Any one know of any good resource to help you calculate this stuff instead of playing random RAM Bingo? ;)

Sorry it is my faulty language skills.

Which memory strap/divider is the most efficient for you? I ask because higher frequency is not always the most efficient.

Luumi
06-09-2013, 10:25 AM
Well I have got my best results using 100 strap and 2400 memory multiplier. I tried some using 125 strap with memory at 2400 with cl8 and tighter, but didn't really improve. Using only 2500 sticks at 2600+ 9-11-9 looked very promising, but not stable :p.

HiVizMan
06-09-2013, 10:55 AM
Ah ok. Did you do any tests with tighter latency and lower frequency.

I have seen some gains with lower but much tighter latency.

Luumi
06-09-2013, 10:57 AM
The one I let to finish got 37s if I remember right. On all other attemps the first loop times were bad, so I just cancelled the run. When I tried to run over 2600 the inital value was 04.4 seconds something and loop 1 was exactly 18s so it would have been great I guess but old good not exact in round popped :P.

Actually, they're set to max values.
This mem doesn't work like I thought. Hope it's because I don't know how to make it run faster(

HiVizMan, could you put me on right direction in OCing this kit?

Now it looks like so:

It's a mix of XMP profile and predesigned Hyper profile. Used RIVE Hyper profile to fill settings those are missing in XMP.

Wow that's great)
Well, my old RAM is 2133 9-11-10-28 1.65v. So my suggestions are like I should be able to run this RAM on the same freq as an old one but with thinner timings, that should result in lower latency and maybe some little bandwidth gain.
Also I'm interested in some freq OC, hope that RAM can operate at 2500MHz with CL10 or even 9 :D (Ambient temps off course)

Actually buying this kit is how I prepare for Ivy-E.

My question is following: profits of Elpida Hyper vs Hynix (my new ram vs old) are clear - thinner 1st timings.
But seems that there's an opposite side. What am I loosing with new mem?

Dart,
I got mine from a combination of searching ebay and several forums that have hardware for sell sections, I got one set of pi from USA, one from Australia, and I have one 3 stick set that came from Russia that I have been hoping to find another matching set so I could get a set of 4 for use. it is he same low timings but the old Corsair Dominator with the tall heat spreader. I always wanted those from years back and thought they would look the best on the ROG board, but what do I do with 3?

Menthol
07-17-2013, 11:34 AM
What I found while searching for psc chips is a lot of them were from the X58 era, so they were in combinations of 3 or 6 modules. they still do very well on a X79 in 3 way. This is how I verified what chips were on the modules.

I also had R2E and R3E, I raised 7 kids so most my old systems find a home in the family, all are grown and gone except I have one son still at home, soon they will go to my Grandson's, for now they are to young and get tablets as gifts from grandpa, lol

Pi Kits are PSC, with my personal experience on PSC 2400 C7 and 2600/2666 C8 should be doable on air with enough volts depending on the CPU of course, I could only ever get 2400 C7 on my 8350, was never possible with any of my intel CPUs :(

Actually, we all know if such kit doesn't clocks well it doesn't costs anything. And honestly, it doesn't even matter if it's new or not.
I did (many of us did) spend some time and money for binning PSC X kits and it's all about luck to get a real good one.
Even G.Skill Pi label doesn't guarantees you anything. (I saw some 2000+Mhz Pi those were rubbish)

150$ is a maximum reasonable price for untested kit of two Pi sticks.

ObscureParadox-OC
03-08-2014, 10:27 AM
I would assume that Super Pi would like quad if you have it available to you, especially for 32M where ram bandwidth is very important.

As for using PSC on Ivy-E I have had it working here no problems. In fact it is the only memory IC I have ever ran on it since the chip can easily take 2666MHz ram.

I wish they still made PSC ram, god knows it's pretty much the best stuff I have ever used and yet it is so old now.

Hello people at ROG!

I've been away quite a lot during the last 8+ months due to army but luckily I can see it ending quite soon. Anyhow, I got some interesting results today after accidentally seeing a post at XS about flashing SPD on memory.

If you remember my Dominator GT sticks from last spring/early summer, no matter whether the voltage was 1.65v or 1.775v, they could post and maybe boot at 2400 tight psc preset 7-11-7, but they instantly crashed after I started 32m. Now after trying with flashed 2500 viper II sector 5 SPD, raising voltage actually does something. Here you can see I did fast and easy 32m run with settings I mentioned with 1.775v.

I have some dominator GT V7.1 PSC kits here that do them sort of speeds with 1.85V.

They also do 2666C8 with 1.92V if you are brave enough to try it. I don't think there is any danger of them breaking if they are only used for short benching periods with those kind of volts but I can't guarantee it of course and I wouldn't want you to try it if you weren't comfortable doing it.

Dartmaul
03-11-2014, 08:34 PM
Actually, RAM is pretty strong against high vDIMM. All up to 2.1 is safe for air cooled sticks.
The thing is about the IMC. On haswell vDIMM and VCCSA voltages aren't linked much so it's pretty doable to use that high vDIMM but on X79, where getting above 1.25v on VCCSA is almost guaranteed way to cause CPU degradation, it would be quite complicated to use vDIMM over 1.9v. At least raising vDIMM-VCCSA delta would bring instability.

Arne Saknussemm
03-29-2014, 10:39 AM
WTF is going on with RAM these days?

As some of you know I am looking about for RAM in a "I'll get something if it's better than what I have" kind of way....

I have some Dominator Platinum 2133 Cas 9 ram which has some pretty good ICs: Samsung...and I have got 2448 Cas 9 out of them.

If I do the typical Cas/Frequency x 2000 I get 7.35ns...pretty quick and at quad channel.

So I'm looking about and see new kits with high frequencies and high prices and I start doing the same kind of sums.

2933 Cas 12 = 8.18ns
2800 Cas 11 = 7.86ns
2800 Cas 12 = 8.5ns
2666 Cas 11 = 8.25ns
2400 Cas 10 = 8.33ns
2400 cas 9 = 7.5ns

So on the face of it, not knowing if any of those kits will OC as well as what I have I am left pretty unimpressed! and the most impressive is the 2400 Cas 9

Is that calculation simply not valid as a comparative tool....is a 2800 Cas 11 much more efficient in some way this calculation does not show and in reality will blow the socks off my kit?

Do I really have to go to old PSC kits with 2133 Cas7 and 2000 Cas 6 for performance?!?

Menthol
03-29-2014, 04:30 PM
Quit the conundrum isn't it. My meager experience is it is very tough to beat psc at 2400 cl7, tight psc setting.
If something prefers high frequency I believe your Platinum's will do as good as any set, what a ***** when you're looking for something aye.
Your Platinum's are the same ver. number as my 2666 kit. Mine will run 2400 at tight Samsung cl9 settings without a problem or if you loosen the timings

Been drooling over the 290X Matrix, I'm super happy with my 7970 matrix(es) and that there 290X Matrix is one fine piece of PCB

ARGHHH after a good wait they couldn't get it! have written to some place in Holland now to see if they have some...

Anyone tried a 2933 CAS12 kit? and got some benchmarks?

EDIT2: No go Holland have run out too :-(

However I have just heard Corsair will be releasing 3200 CAS11 ! Nice! http://www.expertreviews.co.uk/ram/1300276/3-200mhz-corsair-vengeance-pro-ddr3-ram-incoming

It seem like the companys are trying to make the Samsungs stand out.. But it cant be an easy task

some of the Crucial/Microns are nice, ( D9 GTR/DDR3) and when DDR4 is showing up, i believe Micron is going to be the IC to get..

Elpida--> Micron

Would be fun to hear Raja, what he know about the DDR4, who is going to make what, and so on.. what to look for, and the potential golden nuggets (for OC)

i understand Elpida is now a part of Micron.. IC line up?

Rockford

anything with heatspreaders that actually work = not gskil

Go for the doms, between those kits

most of the ram today, is for looks..

They stick the extremely poor thermal tape between the IC's and the spreaders..

Result, when overclocking high and benching, the IC's cook under the tape (more or less), leaving the spreaders not even warm..

Yeah point a fan, the only things getting cooled, is the side plates..

Many IC's die this way, especially Hypers which get VERY hot when OC

I dont know how the doms are constructed, but i bet its better than the other looser kits up there (G.skill)

it was talk before, that you could swap the leds for red etc. on the plat's, to other colors

Customize your look

The integrated light bar provides a subtle downwash lighting effect that gives your system an impressive look but subtle look. Additional light bars (available separately, beginning September 2012) allow you to match your system’s color scheme.

Trident X

i just dont get it..

Cool heat spreader design

>> from G.Skill

Removable Heat Spreader Fin

Our TridentX series features a removable heat spreader fin to improve your cooling options. With the heat spreader fin, the increased surface area helps keep the memory cooler. On the other hand, with a system that already has a sufficient cooling solution; the fins can be removed to accommodate massive CPU coolers or other customized cooling solutions. Please refer to the following user guide.

36133

But they have used a ultra crappy adhesive tape, which more or less will make the overall cooling design pretty worthless?, and conduct like crap

Beats me

If they had put a prime thermal pad there instead.. Now we talking..

Ok many RMA's, PCB sliding out of the spreaders.. Well drill 3 holes through the top of the PCB and the spreader, and add 3 screws.. and while they are on it, remove the stickers from the sides (now the cooling performance gets even better, if a fan are used), and make a cool engraving instead.. cut or laser? they come with a fatty pricetag, so there should be room for that?

36134

Ps: Dude!!!!!!!! what are you doing!!!! IC's should not be in the tape

And Arne..

Do we really want to support this "cheating"

Trident X IC's >> 2600mhz CL10

36135

Ok this stock solution wont bother/cause any issues in 99,95% of the users, since they dont OC the mem so hard, but they are being marketed as a overclocking mem, fastest in the world and all.. and they come with adhesive tape!!
