Help Overclocking Phenom 2 x4 955 Black Edition

post #1 of 11
Thread Starter 
Pretty much, I can't get it past 3.6GHz.
I've changed the multiplier x18, put the core v to 1.38...

Anything else I try to do to make it higher doesn't work.

When running Prime 95 for 3 hours, the temp is usually around 40-44C.




Motherboard: MSI NF750-G55
AMD Phenom 2 x4 955 3.2GHz
Corsair 700w PSU
Corsair H50 Cooler
8GB Kingston Hyper X DDR3 1333
DVD Drive
640 GB HD
Video: GTX 560ti

If anyone can help me, I'd like to achieve 3.8 - 4.0GHz, if possible, with my computer.

Thank you.

I wouldn't go too high on that board anyway, but one thing you can try is disable cool n quiet and C1E support.


Shows power phases on AMD motherboards, your board they recommend 125w+ so itll be alright, but dont push too far, probably dont go over 1.45V

me & reflex have listed this as 125W+ recommended because we apparently find this board to be an add one out - as in, doesn't really fail hard like the other MSI boards. Perhaps we're just not seeing it though. I still suggest you be careful... 1.45V limit is a good one to set

I put the voltage on 1.45 and changed the multiplier to x19 and no luck. I can get to the desktop at 3.8ghz but when I start prime 95 it immediately crashes and I get a blue screen. Should I go about it another way? Like changing the fsb or something else?

what bios settings do you use to reach 4ghz stable? I cant even get 3.7ghz.

umm well I used the cpu voltage setting an NB speed to 2600 and then set the multiplier to 20x
post #9 of 11
Did you try disabling cool n quiet? with it on I crash at 3.8, without it I can undervolt at 3.8 and be stable. Also is your 8gb of ram a 4x2gb or a 2x4gb? Having all slots occupied can sometimes cause issues.

And you can also try leaving the multiplier at 18x, then using the fsb from there, just make sure you dont go too high on your memory because then that will be unstable. Good luck
