Hey guys, total n00b here.

How difficult is it to overclock an ATI X800 XL (AGP interface)? Can I expect to bring it up to performance of the higher end models of the X800 family (XT/PE)? Do I need aftermarket heat sinks and fans to avoid overheating the core? Any help in this would be appreciated...

Thanks a ton, guys!!!

It's pretty easy to overclock it, but you can't get very far at all. I happen to have an X800 XL AGP, myself, and after installing a Zalman VF700 and the accompanying ramsinks, I could barely get any kind of overclock.

The reason is that the R430 core that X800 XLs use is optimized for low-cost, not high-quality, according to this wikipedia article:

http://en.wikipedia.org/wiki/Radeon_R420

I'd still recommend replacing the cooler on there with a Zalman or somesuch to cut down on the noise, though.

Dont go with the Zalman if your goal is to lower the temps as well as cut down on noise.

Get this instead http://www.newegg.com/Product/Prod [...] 6835186129

Thanks, guys.

I really am not that concerned about the noise. I just want to overclock my core GPU about 30-50 Mhz without frying it. Do I need aftermarket hardware to do so, or am I ok just loading the ATItools and going with that?

Also, is there a software utility I can use to monitor the status of the GPU fan??? This is my second X800 XL card, the first one crapped out because the fan stopped working.

Then you need to go with the Arctic Silencer as it will make the biggest difference in temps. Not the Zalman.

The Arctic Silencer channels the hot air out the back of your case.

It's not the best overclocker, but with some sort of aftermarket cooling you could expect to get 30-50MHz more from the core. I've OC my X800XL 30MHz core and 15MHz on the mem with stock cooling. My full load temps are around 60-65C.
