Phenom II advice needed

post #1 of 12
Thread Starter 
I bought a Phenom II 955BE a while ago, but i could never OC it due to the high temps: 40~45 °C idle, 55~65 °C full load, everything at stock. Then i changed to a thermaltake V1 cooler, which only decreased my full load temps by 2°. I tried to overlook this cause i could run any game.
But now that im getting another HD5870 to CF, i wanna make sure there is no bottleneck at all. So i want to OC my cpu past the 3.6GHz (as i was recommended).
I beg for any advice, thanks!

also, money is not a problem, i just wanna be able to run a stable system.

Get a better cpu cooler. A CM Hyper 212+ will be fine and get you around 3.8Ghz.
Also note that the max temp for these chips is 62°C.

I agree. The V1 is not a good cooler--I used to have one. The 212+ is great.

I'd look into a used h50/h70 or a NH-D14, they sell for great prices used (around $45) and offer some great cooling performance. To get the most out of crossfire you might have to get a max oc then experiment with HT speeds.

If money isn't an option get a Rasa kit.

Going to run overclocked CPU with two 5870's on a 650W PSU eh? The 955 is not going to bottleneck anything as long as you are at a high resolution. I assume you would be way higher than 1080p if you are even considering getting a second HD 5870.

Overclocked 955 and two 5870's is really going to push that PSU unless it's a really high quality unit. Might want to kick it up to a 750w unit.

You SHOULD be able to do do about 3.4Ghz at least on stock volts. Is yours a C2 or C3? On my C3 965 I can undervolt to about 1.284v and overclock to 3.6Ghz stable.

I can undervolt mine as well and still run at around 3.4-5ish. That will help with temps.

Make sure to get a good TIM and use the proper amount (not too much, not too little.)

I had mine running at 1.42v @ 4.0ghz and hit temps no higher than 53*c in prime with my h50, this was in a room typically around 77*F.

IF you get an H50, make sure to get 2 good fans for a push/pull config. It will help.
