What's the best way to overclock a Radeon?

[Flatline]

I have a Radeon 64 DDR VIVO, and while I have absolutely no problems with the card's performance, I am also not averse to squeezing a bit more out of my card. I'd like to know what the best strategies for overclocking a Radeon would be and how stable the card would run after the OC.

Try the Radeon Tweaker Link. Upon installing it will ask for another program called GTK+ it will automatically direct you to the site for it.

rage3d.com is a good site to discuss ATI vid cards.

Just pump up the core/mem- don't choose asynchronous for the Radeon- at small increments and run some benchmark for it like 3dmark, game demos and check for artifacts and see if it crash or hang up.

There is a option in the overclocking page of the Radeon tweaker that say 'load these settings when windows start' You might want to find the highest stable setting before you enabling that option. If you don't enable that option, the overclocking will reset after restart windows.

Someone asked that question a while back, you might want to talk to him. Radeon VIVO o/c

The Link for the Radeon tweaker is here. I cut and paste from the other thread.

R3DTweak is a good utility. It uses the existing property pages making it a nice clean interface. Also there are alot of the registry tweaks available in a nice GUI interface. My Radeon 32DDR Retail has been running at 183/183 for months now and is rock stable. (Make sure you set it back to defaults and uninstall it before changing your Radeon drivers.)

I like Powerstrip; It's effective, and has some display settings for when I play DVDs.

As for the limits to overclocking the Radeon 64mb ViVo, if it's an older Retail card (clocked default to 184/184), then you should be able to get up past 200/200 with little problem. The core limit seems to be around 220-230mhz for those, and the ram around 210mhz. Recently, a stealth improvement was made to the Retail Radeon 64mb ViVo, with the addition of 5ns ram (down from 5.5ns ram) and an increased clock speed of 198/198. Some of those have clocked past 250mhz core (highest I've seen was over 270), and the memory past 230mhz.
