720be higher OC

post #1 of 3
Thread Starter 
I've managed to get my sig rig up to 3.6Ghz stable, but past that I run into instability, usually a BSOD when running IBT.

Are there some other settings I should be messing with besides vcore and NB (or should I touch NB voltage at all)?

Current settings:
3.6Ghz (18*200) at 1.425v
NB at 1.275v (I forgot what the default was, but right now it's at this)

I'm willing to try anything you think is safe. My temps are good. I'd love to get to 3.8Ghz stable, 4 if possible.

Let's see if we can get you there... But please know that the fact that your chip is a C2 revision will make it a bit harder to OC than if you had a C3 revision.


1. What is your CPU-NB at? Speed/Voltage please
2. Is your RAM configured correctly?
3. Try Prime95 at the settings you have now and see if it holds up and the temperatures are still good. IBT is not as "hard" on the CPU as Prime95 so you may be passing IBT and fail Prime right away.

From looking at your screenshot; I would say that you're on par with what C2 720s will do on air. I have one of them and it runs perfectly at 3600 with about 1.4V (just like yours), but to get it to go higher I have to up the VCore and teh temps shoot up to unsafe territory quite fast.

Reduce RAM speed to 1600; up CPU/NB voltage to 1.3+; try different combinations of HTT+CPU Multiplier to reach higher clocks.
