Help needed to OC i7 950

I'm glad that helped. What I meant when I said your temps were a little high is that you should either stop there or upgrade your cooler if you want more overclocking. I disable HT because it requires more power, generates more heat, and I don't use any applications that use more than four cores. If you do disable it, you should notice that the CPU will stabilize at a lower voltage, all while producing less heat. I wouldn't let my i7 reach 80 C, even if that's a reading from your hottest core. That's a little much. On a day to day basis, you will probably want to keep your CPU in the 60 C range max. Another thing I should point out is that if you do turn on the power saving features, you'll want to use a CPU voltage offset in your BIOS instead of simply entering a value for the voltage (ask if you aren't sure how to adjust this- basically it adds a certain amount of voltage to your CPU compared to what the BIOS would normally give it depending on how much load it's under). This is where the real power and heat savings will come in. The last thing you should note is that you'll probably want to avoid load line calibration (if your motherboard supports it) and instead opt to find the right CPU offset to keep your system stable. This is the safest way to run a 24/7 PC.

Hi, I'm definitely going to stop here, believe me. After all my goal was to reach 4ghz with a stable rig. I think i'm gonna turn HT off for now and see what happen with the temps. Too bad because I've heard that DX11 supports HT. Next gen DX11 games might make use of HT but as for now they are no real advantages to keep HT on. What you think? Lastly i will try to back the cpu voltage down a bit. Every time i touch that value though window crash or doesn't boot.. I agree with you about the cpu fan but the next time i upgrade i'm going sandy bridge with liquid cooling. So for now i'm stuck with this:sad:

I didn't understandt the voltage offset part much. Could you take a screenshoot of your bios?
 
In regards to your question about HT and current games, it has been shown to not help performance. The CPU offset setting is on the same line you enter in the CPU voltage (just highlight that field and it'll show you how to use an offset instead of a fixed voltage setting).

Well i did turn the the HT off, blck 175 and the voltage down to 127500. The temperatures came down quite a bit. Intel burn test showed 74 at the max setting(used to be 80). 1.5 h of dead rising 2 showed a max of 69(it was 75 with with HT on). Sure it could be better but it's stable and reasonably cool for the cpu fan/case i've got, considering that before the OC intel burn test my cpu topped at 63 degree. I'm not touching it anymore:clap:

Cool! What value do you recommend?

Use whatever offset will give you just enough voltage to match the one you needed under load when you were using a fixed voltage. Because vdroop will take quite a bit of voltage away, you'll need to set it high enough to compensate. If you don't know what this voltage is yet, do a couple tests on OCCT and it'll give you a voltage as a function of time graph when it completes or fails. On my graphs, for example, it's pretty easy to see that at 4.2 GHz, I'm crashing within an hour when the voltage is just under 1.29v, but passing if it's above. You should see that kind of result if you do enough testing, and you just need to make sure you're getting that borderline voltage (or a little bit more if you want to be safe) with the offset you chose.
 
I used the 3 step RJ posted and got my new 920 D0 to 4ghz in a snap. 1.3v (windows shows 1.28). Prime stable after 5 hours, temps were in the low 70s on a venemous x. (would be watercooled but i got screwed over by a member here for my block).

Loving this x58a-ud5.
 
Havent tried them yet, im gonna bump up the bclk to 233 so i can get my ram running full tilt. Im assuming im going to need a vcore of at least 1.35 to get that.
