What works?

Oh also -

MrCourgar just text me and asked me to reply to you for him. He said 4.5 is great, 5+ is even better, so where does he start? He also said he would love 7+ but can't afford LN2.

LOL at both of you.

OK right after I finish feeding my kids I will post up a simple settings framework that both (or only one of you) are welcome to try.

[kkn]

jawbone: thats liquid nitrogen ( below -200C ) LN2
hiviz he posted hes gona use water ( start of tread )
-> Currently everything is stock, but when I get off shift (I am a firefighter so on for a few more days) all my water cooling material will be waiting for me at home. It is a full water cooling system with CPU, GPU, RAM, NB, and SB all being used, with 3 possibly 4 radiators on 2 seprate yet intertwined circuits (one will dump into the other so the water gets used through out the system). The CPU will have a 360 radiator dedicated just to it and a 240 and (2?) 120 for everything else. <-
ive read that there are those who run 4.6 or 4.8 ghz and turbo up when on load to 5 - 5.2ghz on full load.
i guess they have it on some good cooling ( depends on the room temps too i guess )
and you can set a max limit in bios on the temp so the pc shuts down when it hits the limit to prevent damaging the cpu and other things.

Awesome, thanks man! I know I speak for both of us when I say we appreciate it Paul and myself (I'm Jared) are both great when it comes to computers, but we're both just starting to get into the overclocking world since we now have systems that can. So we're both pretty noob at it. I used to be a PC technician but never overclocked so I don't know much about it.

Also, I can't seem to get my ram to run at 1866mhz. In my bios it's set to auto and to that speed, but when I run CPU-Z in windows (win7 ultimate) it shows it running at freakin 800mhz. Any idea what's wrong? I'm sure I have the voltages or timing wrong.

The only reason I chose 1866 over 2133 like Paul has, is I read (here in this forum, actually) that the AMD FX8150's memory controller couldn't handle over 1866. Paul has gotten his system to run 2133 fine, but that's neither here nor there.

im running 1600 my self and i have no problem seting it that way.
under extreeme tweaker in bios -> memmory frequensy ( if you havent fiddling whit enny thing else ) set it at the one your chips is on
by the way what bios are your using?

[mrcougar53]

I got mine to run 2133 through the bios and cpu-z confirms it.

HiVis - I am looking forward to getting those numbers from you and testing them out tuesday when I get off, but with full water cooling do you (or anyone else out there in ROG world) think I could get close to 6ghz as long as I'm not taxing the system? And for the 4.5+ ghz can I do this and keep all 8 cores running? Yea its great to have those numbers of 7.5 but if it's only using 2 cores then are you really getting any thing faster?? 3.6(stock)x8=28.8ghz 7.5x2=15ghz If I understand it correctly

KKN - what do you mean "Turbo up." Using the auto overclock in the BIOS it did not show a predicted change to the speed so I didn't even try it.

Jawbone - be jealous be very jealous!! That is what happens when you give up time at home and with friends and family to work.......

i dont know how it work my self so ( havent clocked mutch my self ( newbie on OC so ) ).

[HiVizMan]

You can (could) get to 6GHz on two cores on a good water cooling system. I am not sure why one would want to but can understand the appeal. Guys got side tracked with the kids last night so will be posting up the framework later today.

Cheers

[mrcougar53]

Thank you HI VIs, and while you're doing that one more question...... Am I right in the assumption of how the overclocking in relation to amount of cores works? Ex: 4.5ghz with all 8 cores effectivly runs at 36ghz, and 7.5 ghz with 2 cores effectivly runs at 15 ghz?

[HiVizMan]

Nah that is not how it works, or how one should think of the frequency of a CPU.

Regardless of how many active cores you might have your frequency is that number (MHz) which is the highest frequency your CPU has achieved on a single core, or on two cores depending how many you can switch off in BIOS. So for example that 8150 screen that I posted is 7.45GHz regardless of how many cores are active the frequency is 7.45GHz. If I had clocked it at 4 cores or 6 cores to that frequency it matters not one wit.

When I said you could get 6GHz on two core you are correct in thinking I am saying it is easier to overclock only two of the total number of cores present on the Bulldozer CPU, the why that is so has to do with the amount of heat that all the cores produce when voltage is being pumped through the CPU. Fewer cores equals less voltage and less voltage means less heat generation. Plus having a couple of cores disabled puts far less stress on the CPU itself and you can theoretically gain a higher overclock that way.

Guys I am a little tied up the next couple of hours/days I have not forgotten or discounted the step by step reference guide for the both of you. Just a bit pushed for time to sit down and do it.

In the mean time you can both ensure you have the right software installed on your systems to play with your kit.
