Safe OC (voltage) for stock cooler?

post #1 of 10
Thread Starter 
I've read around some and a few people have gotten decent clocks on stock cooling with Athlon II's. What would be a "no no" voltage? I can't seem to find the TDP of my board AND it only has a 4-pin CPU power connection. If I could get to ~3.5 on stock, that would be great. BUT....I don't know what voltage is too much.

I do plan on getting better cooling, but it seems as though I need to OC a bit before I can get my hands on one..... Plus, I would like to see how well these stock coolers actually are.

Note: my apartment is really cold.

It's going to be tough to overclock really high with your setup. I would expect no more than a 20% increase based on your hardware. Try setting the system clock to 220. Add some more voltage to your CPU and CPU/NB. You may have to back your RAM down a step because RAM is the most difficult to overclock. Let us know how you make out.

1.42 volts is the max. and that is kind of iffy. please get something better. a hyper212 lets my X6 hit 1.5 volts without breaking a sweat.

I took my AMD X3 445 to 1.408 on stock cooling. I wouldn't really run Prime95 or anything at that voltage on stock though for very long. It ran pretty damn hot. Like 40 Idle.

That's what I plan on getting.

I'm not expecting much right off the bat and I can supposedly get 20% with the "OC Switch" on the board (yea, we'll see how well that works out. I won't hold my breath.).

Due to (I think) the limitations of the Athlon memory controller, my RAM is already backed way down and I haven't even touched it. It's at 1066 with something like 9-9-9-24 timings.

I'm not going for crazy benches, just something stable. I created another post earlier (I have encountered very poor chip performance....) and it made me realize I need some sort of OC just to not want to punch my rig.....which would be worse.

I was able to get to 3.45ghz via the "Easy OC Switch" alone. That brought my RAM up to something like 1226/8-8-8-19. Seems somewhat better: ~27c idle and ~43 under load. I ran Prime95 for about 15 minutes with no issue. I'll run it overnight and see how it does. The "stutter" isn't as pronounced, I don't think.

Mine is 40-41c on idle. During Prime95, 61c is the highest temp, during OCCT, 65c. However during playing game (Alice Madness Returns, Assasin Creed) while surfing, and downloading and listening to winamp, 45c is the max. OC to 3.6Ghz and having the same result. But now I revert to 16.5 because I'm not gonna OC further until I get a better mobo. I admit air ventilation and temp in my room are not that good cause I depend on fan 24/7 in my room. Do you think it's too hot for my pc. I think it is
