overclocking my video card

[jawknee530]

I want to over-clock the video card in my sig. I'm familiar with over-clocking processors but I've never tried to over-clock a video card. there's an option in my bios to change the pci-e speed; is that what you change to change your video card speed? if i change it from 100 to 110 will that increase the clock speed and memory of my video card by 10%?

No, why would changing the speed of your PCI-E bus change the core or memory speeds of your video card? Use ATI Tool to overclock your video card.

No, not one bit. Don't bother with the PCI-E speed, it won't do a thing in real life performance.

You need a program like ATI Tray Tools to overclock your video card GPU and RAM. Your BIOS has nothing to do in this situation. And try to read some guides on how to do it - search on Google, there's tons of documentation on that.

thanks for answering my question. I've tried to use Catalyst Control Center to up the clock-speed but it won't stick. I'll set it and a few moments later it goes back to defaults. i have a VF900 so I don't think that heat should be an issue.

If you are going to oc that use ati tool it has a autofunction that does everything for you and scanse for artifacts. OC'd my laptop over 13% with atitool and only stopped because I didn't want to fry something because of my laptops crappy ocing. I have heard some programs don't work with the 1900 so check before using. If you are feeling confident you can move up to Riva tuner (which I believe works with all ATI cards) which has tons more stuff than just clock control such as unlocking pipelines in your card. Good luck. Also most programs require you to test for stability before appling settings another good test is 3D mark or a GPU intensive game bench. Finally your PCI express bandwidth is plenty for you card even 8x wouldn't limit it much.
