The BIOS affects NB oc/stability very much.

I didn't pay attention to it thinking 1.13B for the MSI was good enough, but above 2083MHz 1.25VID NB it would become unstable after 3-8 hours gaming. So I dropped it down thinking it's a CPU limit. You know, when you test and already find the limit of your CPU, you don't tend to push to it repeatedly, believing that is the actual limit. Hence I always stuck below 2080MHz 1.25VID.

Until, I had the chance to test BIOS P0J. I was at 201HT, so I just changed multiplier up to 11x and... P0J turned out to be 100% stable at even 2211MHz 1.25VID. I did not try more at stock VID.




I know 2375MHz required 1.300VID, so anywhere from 2211-2370 may be possible yet at 1.25VID. Just goes to show the difference between the quality of the BIOS.

It's strange because at nb speed of 2034 it's as stable as a rock yet it locks immediately I try 2052mhz. The 18mhz jump is caused by AOD not having a selection at 227htt.
That's not AOD actually, that'll be a BIOS limitation. AOD can only move and pickup what your BIOS allows.
