Phenom II 945 can't reach 4 Ghz? - Page 2

post #11 of 23
I dont recommend you try 1.5v on your board. Also when I had my 945 (C3) it took me 1.51v to get it stable at 4ghz. I dont think your going to be able to do it with a C2.

Ok guys. Thanks for all the advices. One more question regarding the CPU temps, even though i made another topic a few months ago i'm still not sure what are my real temps of the cpu, the cpu core temps being about 10 C degrees lower than the CPU temp. In full load with prime95 the temps are about 40-45 core temps and 50-54 cpu temp. In idle 25-30 and 35-40.

62'c max on the cpu

55'c max on the core

after that it will become instable

I've yet to see a C2 stepping CPU get to 4 GHz 24/7 stable on air. Sorry, dude .

Teehee my B55 is more stable than your 945..

mine wont go past 4.1ghz on this mobo but i can bench at 4ghz NB with ambient temps.
total waste of time due to having 800mhz ram that wont go past 910mhz though!

If i couldnt get 4ghz i would lower the cpu till its stable then give the CPU-NB more attention,by far the most tangible reward for overclocking.

These chips need a lot of voltage I was stable at 3.8Ghz on 1.45v, with timings closest to stock as I could on RAM, but would start getting errors after passing just a few seconds on prime95, even though my temps were only hitting 50C. The higher the OC, the more likely you'll get an unstable chip, even if you were hitting temperatures you were before.

not worth it, just go for whatever clock that max at 1.45v. Unless you're some kind of "enthusiasts" like some of us here, you might risk frying/degrading your cpu.

I hate that my GPU can be overclocked stable till 950/1300 and this CPU can't even reach 4ghz without 1020303432 trials.

Ill give it a go at ~1.45 and see how high i can go on the frequency. Thanks.
