Intel Nehalem Absolutely Insane -> 975 ^^

[saaya]

I've had at least 5 920's that wouldn't do 4Ghz on water, no matter what. Because some CPUs don't like the 21x/20 multipliers, and they don't run high BCLK either

I agree on that, my 975 doesn't seem to like more than ~1,53V Vcore for example
But it does run higher than 4,6

cpus not "liking" 20/21 multis is a board problem
its when the TDP TDC exceeds the programmed value, then the cpu will become unstable and crash, thats a board problem. on BloodRage you can completely cut the tdp and tdc reading for the cpu, dont know about other boards but id be surprised if they dont do it... i think they adjusted this in the more recent bios files though and at least manipulated the tdp tdc reading of the cpu so you can clock higher.

im sure if youd try those cpus again you could hit 4G easily

whats the max 3d stable bclock pcriminal?
