I've left the multiplier at 9x:
- I started with the mobo automatically chosing voltages. I jumped to 3.0 ghz fine.
- Then I set the vcore to 1.3V. Oced to 3.1, 3.2 and 3.3. Core temps were fine.
- Oced to 3.4ghz, and the system would crash on PRIME95
- Increased vcore to 1.4, and achieved 3.4 ghz. Core temps were ~60C stressed. Ran Prime95 for ~10 minutes without problems
- Set it to 3.5 ghz. Bios would check out, but Vista wouldn't load.
- Dropped back down to 3.4 ghz. Dropped vcore to 1.35. Ran Prime95 ~10 minutes and 3dmark06 (scored 14832).
Core temps were all below 60C stressed.
I think 3.4 ghz is about my limit. 3.5ghz is not stable at 1.4V and my core temps were 60C stressed at 3.4ghz@1.4v. I don't want to exceed 65 C....
Questions:
1. The vcore requiements seem to ramp up as you push the cpu harder. How do guys get to 4.0 ghz without exceeding the 1.5V spec limit? I know they're using watercooling, etc but right now it seems I'll reach the 1.5v limit before the temperature limit.
2. I've got my ram voltage set a 2.2v per the spec. And the ram multiplier set at 2.0 for the 1:1 synchronous mode. I haven't messed with any other ram setting (couldn't find any other setting). Anyway, my RAM is now underclocked at 755 mhz (9*377=3.4ghz, so 2*377=755) instead of the original 800 mrz.
Thoughts?
This is my first build, and first oc. I've tried to do my homework, but don't expect me to be too smart just yet.
