Help me oc my 7900gt

post #1 of 10
Thread Starter 
Ok just installed the evga7900gtco last night with the zalman vf900 and its running super cool at 32c. For some reason I can't overclock though. Coolbits won't let me move the slider, or auto detect. Any ideas?

Thanks.

What drivers are you using? There are new releases on the Nvidia website. Did you clean out your prior drivers with Driver Cleaner?

I know I'm a noob, but ATI tools for nvidia? And could my problem be from running xp64? I did use driver cleaner, and downloaded the 84.25 that was released yesterday for xp64.

Hey thanks for the beta tip, It works. My 3dmark05 jumped from 7500 to 9500. But I can't understand why it says the core is 500, and the mem is 375? is there another way to tell what my speed is?

Thanks again...

if you are using ati tool and getting those numbers it is 500mhz core speed and 375mhz X4 to get 1500mhz memory speed. Hope that clears it up

Are you sure you're not looking at the 2D speed? The 3D clock speeds will only go into effect if you have a 3D app running. Otherwise, your card runs 2D speeds while in desktop and 2D apps. (much lower clock speeds)

Ya..ATITool divides your ram speed by 4 for the new cards...I dono why.

So, now that you have the zalman. DO THE 1.55V VMOD!!!

Trust me. You'll smile so wide that you might start crying....it's THAT amazing. Insane clcks, here you come!

Just look it up man...my load temps with the same cooler are 63C...same as stock volts and stock cooler...actually like 2-3C cooler.
