o'clocking Radeon 8500

[Jsnmaj]

I'm looking to o'clock my Radeon 8500 and was looking at this mod here:

I also want to add better cooling to my card and was looking for a place online to get good ramsinks and a better fan for the CPU. Any recommendations?

First I'd overclock the card to see how high it will go with-out the mod if it's a retail card. And I would sit down and watch the entire set of benches in 3DMark2001 to look for any artifacts/corruption so I knew how high it was actually going with out any artifacts.

From what i've read from many different people, that guy was lucky from the start and had a great stock overclocker. Is your card OEM/LE?

The thing that really bothers me about that article is that there are NO before and after voltages recorded. He might be happy now, but next week he might be out an 8500 because of high voltages.

You got to have a voltmeter and know how to use it if you start modding like this.

It's a retail.
I figured i'd start with some ram heat sinks and a gpu fan and see how far I can overclock it from there. I've been told with just those mods I can reach 300/300mhz. If that's true I don't think I would take it any further.

Well, I would add more/better cooling and see how far you can get it with power strip. If you want to add more/better cooling, here are my recommendations.


This is a Orb-style rackmount HSF. Better and cheaper than the orb. It has bigger tin fins than a blue orb.

Socket cooler


This is a rackmount cooler, for a 1U. Notice the small fins. That is good, more surpace area. I would add a bigger fan.

Raqckmount copper cooler


I would epoxy that on the 8500, and some copper ram sinks. They will diosperse more heat, and you want to pencil trick it, and that means more voltage, more voltage means more heat. Yo-u will need to dremmel the HSF's to get them to fit due to the caps. I would also recommend that you lap the heatsinks and ramsnks, along with the chips since it seems you want to push it hard. If it is a OEM card, do not expect to push the ram hard unless it is the 3.6 hynix. Also, you will need to put the 8500 in the freezer to get the HSF off of it and a razor blade and goofoff. ATI uses a crappy hard glue on their products and be careful so you do not cut yourself.
