Should I risk OCing this 955? - Page 5

post #41 of 54
Thread Starter 
I dropped the Vcore from 1.4V to 1.325V because the blokes in the AMD - General section said that should be fine - it now loads at 54C after 10 mins of LinX. Ambients are a little lower today but the idle temps were similar, so I'm happy

Might have a little headroom now.

Sorry for triple post :S

I bumped multi to x17 (3400MHz) and put the NB multi to x11 (2200MHz) - is that correct, or does the NB need to be higher/lower?

HT Link is at 2000MHz ie stock

NB will go between 2600 to 3000 depending on how good you NB is but you will need to turn you cpu/nb volts up at some point which will add heat to your cpu because the the NB you are overclocking is on the chip.

Yeah I'm not going to the point of overvolting this time around - so I'd need an NB of 2600 at that clock of 3400, is that what you're saying?

I'm confused :S

Couldn't get it stable at 3.6, even with a voltage bump, which seemed odd, is that because the NB was too low?

Might need 2 bumps. What was your CPU volt set at?

AMD Temp wall rule: You will not be stable or gain a higher OC easily past 55C. Their fab-tech fixed coldboot bugs but sets a pretty low and annoying temp wall.

Don't like to go much further, I was getting the same load temps at stock w/ 1.4v as I'm getting at 3.4 with 1.325v :S

keep it @ 3.4GHz. Temps will go higher.
Try 3.4(CPU) and 2600(CPU/NB)

After some gaming 3.4/2.4 was slightly unstable. I've removed the OC for now, just too limited by heat to do anything about stability.

Thanks again for the help.
