I had my new rig up and running for the past few days and Im running prime95 for stability. Im safely at 8x500= 4ghz with mem running 1:1 at ddr2 1000 and 5,5,5,15 2T - but!
I have to set my vcore at 1.39375v in bios and vtt at 1.3v, vdroops to 1.376v idle and 1.36v load to get 24 hour prime95 stability. My temps are 34c idle and peaked at 60c load. I have seen others get better results with lower vcore but I dont see many of them testing like I do...I ran 1 p95 test for 12 hours and again 1 more for 24 - set my vcore 1 notch lower it bombed twice after about 8 hours p95. Heck, I can go 9x500 for 4.5 ghz but I have to bump vcore up to 1.45v (didnt even try to check for stability)
I decided to try something different. Im running 9x400=3.6ghz right now with mem 1:1 at ddr2 800 and 4,4,4,12 2T at the following:
vcore at 1.3v and vtt at 1.2v, vdroops to 1.28v idle and 1.264v load.....what is amazing is that my idle temp is still about the same at 32c-33c, but my load temp hit a high of only 50c so far and p95 testing I normally see the temps hover between 46c-48c.
What is amazing is that for .1 less in vcore, my temps drop by 10c at load...thats a big difference imo. I know that heat (not vcore) will kill chips and chipsets...if you had this choice, what would most of you guys do, run higher at 4ghz (feels good to pound my chest) or go with 3.6ghz (I will try to lower vcore later but this is my first stability test at 3.6 ghz)?
