amd 965 oc help

post #1 of 11
Thread Starter 
Hi everyone,

Since I just got my new mobo asrock 990fx extreme9 I tried some oc on it (my old mobo is 3+1 phase, could only reach 3.8Ghz stable).
So far I reached 4.1 Ghz stable by just raising the multipliers at stock voltage (1.475V), but with LLC to 100% the voltage is around 1.414 to 1.464. When I try 4.2Ghz prime 95 shut itself down lol. Attached are my settings, and should I now start to increase HT bus speed?

What are your temps at that speed and voltage? Ive seen Phenom 2s with much more voltage applied to them, so you probably have some wriggle room.

That said, not many will go far above 4.2 Ghz. You might just be pushing the limits of your chip.

Thanks! My temp ranges 52-55, and I'm using hyper 212+...

PHII have a max temp rating of 62*C they tend to get kind of finicky when you get into the mid-high 50's. So if you are trying to achiev an overclock to run everyday I would stop there personally. While running prime95 what is your max vcore reading? And your BIOS pic did not show voltages.

when running prime 95 max volt = 1.464
post #6 of 11
For a 24/7 overclock I would say your at just about max safe voltage. I myself would not go any higher.

Generally anything above 4.2 GHz is a wild goose chase with a 965 unless you have a fantastically binned chip or some space age cooling to go along with it. Mine was a champ at 3.8 Ghz for most of its life but was never stable much past that. Just make sure your temps are solidly below or within the 55C threshold as these chips really hate heat.

Also if you want a nice, measurable performance boost try to get that Northbridge to 2600 MHz and above. Northbridge overclocks make a huge difference on the Deneb architecture. Huge.

Good luck either way

alright, thanks I'm trying to raise cpu/nb voltage and increase the NB...what is a good voltage on cpu/nb? Also, my RAM is 1.5V cl9 at 1333, how could I lower the timing?

Thanks, I'll give it a shot!
