Hello.

So i have that beast but 6gb ram version and I would like to upgrade to get some performance. I was looking for discussions but none give me satysfiying answer.. I am wondering what will give me better overall or at least game performance for better price? I am choosing between:
-2x DDR3 4GB Kingston HyperX 1866Mhz 124 for both (later i will buy 1 another set of these, if there will be new bios with unlocked frequencies for 4x4 1866mhz mode)

or just:

-4x DDR3 4GB Kingston 1333Mhz for 19/stick

Cpu-z says that my laptop has 2 completely different modules inside:
2Gb is Samsung PC3-10700 that clock on 667Mhz, the other one 4gb is ASint Technology... (never hear before...sounds like some chinese cheap crap... :)

Thank you for your answers"

Look at http://www.anandtech.com/show/4503/sandy-bridge-memory-scaling-choosing-the-best-ddr3/8

In summary, you gain a tiny nudge in performance from going from 1333 MHz to 1600 MHz, and a minuscule amount more in going from 1600 to 1866. Considering the insane price premium for performance notebook RAM, plus the fact that the G74 will not support 16GB at any speeds other than 1333 Max, IMHO it is not a worthwhile upgrade. I always tell others to buy 1333 RAM and spend the saved $$ on an SSD, which gives you shocking performance gains that you'll notice even after several months!

Wow....this is VERY odd. In every laptop I've seen, the manufacturer uses matched modules. Does this particular unit have a "history?" I.e., is it refurbished, used.or anything like that?

Also, whch configuration is it? I didn't know there was a G74 that ships with 6Gbs....all the ones I've seen (so far) have some number of 5Gb modules, o either 8,12, or 16Gb.

Asus uses many RAM suppliers, including Asint. Whatever brand they install in any particular unit, it meets their specs for that model. I think they're all the same quality.

HI Guys

With all the warnings and options, and diferences. I buy the HYPER X PNP 1600 dual channel. I am very happy with these, beside the analysis on all softaware that exist, these are the best ram so far.

beside the all performace available, there is a big limitarion.
1. these procesors, only work until 1333mhz clock, (if you computer comes with more that 2670 (like mine)) if you go with the next model, sorry is i do not remember the number i7 core processor, then you will see the improvement by far. These does not mean that it will not work. But in my pocket experience, stick until 1600, the improvement is greath.

2. i did buy the second set of ram to jump to 16 gigs. and to start, these computer are limited to dual channel on the first 2 ram modules. (remember 16000 up type) If you use the 1333 it will work if you buy the dual channel ram configuration.

3. the limitation is not the processor, is the BIOS. I have no idea why these is like these for the premium flagship ASUS laptop. The point apply if we are talking about a OC the laptop. But it is crazy to make these done, on these expensive laptos. Buy a desktop to play with OC or buy a laptos that you will see that is more than the 1900 USD. since cpu and gpu is the heaven limitation. Beside there is always a why these laptos goes expensive.

I have being working computer for 25 years. and until now, if you using a ton of programas running on the back. 16 gigs is useless. I am using these computer for my office, photoshop. corel, oracle database, etc. etc. and even that..... i use 6gigs of ram. max 7. and on the gaming part. I do think that you will play 2 games at the same time. So with BF3 MW3. using the complete set of bloatware enciclopedia (and asus keep those conservative) these computer use at the most 5 or 6 gigs. Remember Windows 7 destruy the memory comsumtion like the VISTA OS.

I have right now 105 process and I am using 2.20gb on the home Premium hard drive. NOTE these is the partition that it came with my computer factory. And with games.... is 2 gigs more. max 3. On the win7 pro. the same with out the crap asus softare and using office software full and databases (odbc) still use only 4 gigs. at the most.


rule> buy the 8 gigs of PNP hyperX. happy hollidays and enjoy. PLAY HARD

NOTE> if you want to use nice memory, keep it on 1600 mhz pnp rams. you can find these for 80 usd on amazon.

enjoy.

Your processor you still see it can address a maximum of 32GB at 1333MHz memory. Only the very expensive Extreme Edition CPUs can run 1600MHz memory. In the real-world you will see very little real-world performance difference between 1333 and 1600, unless you're benchmarking. I'm not entirely sure if the BIOS can reduce the memory timings (check with your current modules) but if you can run very low latency 1333 it will be as fast as normal latency 1600 - so even if you buy 1600CL9 and cannot run it at 1600, you could in theory try to drop 1333 down to CL7 to give a similar performance boost. The G74 has four DIMM slots so even if you buy two 4GB modules now you can add 2 more later as well.

32GB evidence. (Credit to For!)

I will ask ColonelS if he can check about the memory timings on the G74.

Unfortunately the G74 BIOS does not let you tweak your latency timings, so you are stuck with the common JEDEC 9-9-9-24 1T timings that are programmed into most 1333MHz modules today. The BIOS will even ignore XMP settings programmed into the modules (e.g. the clock speeds and timings in the Kingston HyperX PnPs, and in the new Corsair line of Vengeance performance RAM for notebooks) in favor of its default. A new more customizable BIOS for the G74 is in order so we can take advantage of what Marshall points out: compensating for slower clocks with tighter timings.

Thanks for the 32GB credit, Marshall!

My model is G74SX-TZ158V it has 3GB VGA, 1x750GB HDD and 6GB RAM.. Some say that 1333mhz with lower latencies will work almost as fast as 1600mhz??? I found Kingston hyperX 1333mhz with cl7..what about that?? If that work good i will 4 pieces of these for 40/stick...

Thank you

In order to avoid problems with mismatched modules, I've decided to grab two of these chips from Corsair. I have a corsair PSU in all of my desktops...However, I don't know what their quality is like on ram. Anyone here can vouch for them and their opinion on this particular model?

Corsair 4GB PC10666 SODIMM Laptop Memory
Memory Category: Laptop
Memory Type: DDR3
Memory Speed: PC10666
Memory Speed MHz: 1333MHz
Memory Size: 4096MB
Total Memory Size: 4GB
Memory Modules: 1
Memory Socket: SODIMM
Memory CAS Latency: 9-9-9-24
Memory Timing: 9-9-9-24
Pins: 204
Voltage: 1.5V
ECC: No

Thanks for looking.

Generally the lower latencies mean a faster RAM clock-for-clock, but to see a substantial performance difference it depends on the particular software package you are using. Some programs like lower latencies and do not respond with a performance increase to higher clocks, whereas with other programs the reverse is true, and lower latencies can mean the sticks perform similar to or better than ones with higher clocks. The only way to find out is to test each scenario and bench, and we can't do that with the G74 'cause we can't tweak our memory timings in the BIOS.
The 1333MHz stuff you mention at CL7 sounds really good actually. There's no way of knowing if the G74's BIOS will accept these tight timings or reset them to its preferred default of 9-9-9-24. Sounds like a really useful experiment that would tell the community alot: go for it!

Corsair modules are generally really good quality, and since they use chips from the same manufacturers as other brands (e.g. crucial, kingston) they will be identical in performance. The only thing where corsair has everyone beat IMHO is their warranty and service. If you find any error in your new sticks with memtest86+, even just one, then those sticks are unacceptable. Corsair will replace them with new ones, end of story. No messy phone calls, emails, just a nice clean RMA procedure and form on their web site. Can't go wrong with customer service like that (from what I hear on these forums ASUS should take lessons!).

...ASUS should take lessons!...

..not just ASUS, I'm taking lessons, too! (The real learning lessons, though.:D)

For a newbie like me, these forums are indeed, my Computer 101.

In my short stay here, the knowledge and the how-to's I've been gathering,
really improved the way I handle my computer hardware and software.

Let's keep it rolling, guys!! (two thumbs up to all!)
