Phenom II 940 overclocking question

post #1 of 6
Thread Starter 
I know the CPU has a serious limit on what it's capable of reaching, but has anyone managed to hit the elusive 4GHz on the Phenom II 940 and had it stable 24/7?

I can go as high as 3.7GHz @ 1.5v but in order to have 3.8GHz stable I need to go beyond the Vcore limit as 1.55v isn't enough.

Would going under water help at all? I heard that these CPUs like lower temps rather than higher volts.

i once had a phenom 940 BE but i couldnt get pass stable 3.66 1.47v and it was watercooled. this chip is very hard to overclock past 3.8 ghz, also the type and amont of Ram you have installed will limit the overclock and the motherboard you have. i saw once this chip reaching more than 4ghz with liquid nitrogen. the Phenoms 955Be and 965BE are better chips to overclock if you want to hit 4ghz and higher, or you could do as me and get Intel I5 760 overclock it past 4ghz and save some money and electricity.

Sounds like we had the same issue, but LN2? Guess that means it has the same problem that the older Athlon X2 and Phenom I tech had.

Alrighty, I guess this is the end of the road for this chip. Time to hunker down and wait for Bulldozer. Thanks!

Well. AMD CPU's need more volt's. On the plus side. AMD Cpu's run much cooler than Intel
