Hey, I have an EVGA 7600gt, I used the coolbits detect optimal frequency, and it gave me 660/800 clocks, can I rely on this, I'm assuming it would be stable because coolbits usually gives a mild overclock. I have stock cooling, the temps are 50c idle and 65c under load, are these safe?
OK, first, I do not think a OC'ed 7600GT will compete with a 7900GS. Ever. But OC'ing definitely gets closer than stock speeds. Your OC is safe now, but try to see if you can get that core up to 700 without crashing. And by doing some reading, don't expect to go much farther than 700/800 without a volt mod.
Now for coolbits, it is simply a regestry entry that allows OC'ing of a nvidia video card. The driver fully supports it, its just locked to begin with. Just Google it, and there is a file you can download and run to use.
This card actually JUST beats a 7900gs in 3dmark06, I compared it to this http://www.nvnews.net/reviews/inno3d_7900gs/page_2.shtm....
I scored about 5 points higher lol, but it if I had the same cpu as they did then I would be getting about 70 points higher. But you have to keep in mind that a overclocked 7900gs would DESTROY a 7600gt.
Now save it as coolbits.reg. Double click it and add it to your registry. Restart your computer, go to properties>settings>advanced, then click on the 7600gt tab, and now you can look at all your new options. OR you could just download rivatuner and use that.
65c at full load sounds like a very safe temperature. My overclocked XFX 7900GS gets around 74c at full load and from the information on all the forums, 74c is safe for most GPU cards. Once you start reaching over 80c is probably when you need to consider a new cooler/fan option.
