ATI Radeon 9800 Pro - My Overclocking Results *PIC*

[DohDoh]

I recently purchased a Koolance Exos Al water cooling kit. The video card is now being cooled by the Koolance GPU 180-L06 water block.

Here are my results using ATI Tool:

Chip Type: R350
Engine Core Clock - 430Mhz
Memory Clock - 370/740Mhz

If I go any higher I get random lock ups, artifacts, graphic blurs, etc. So these numbers have been stable after long testing and after gaming.

My question is should I attempt to raise the voltage? Is it even worth it? I seriously doubt raising the voltage will gain any extra speed on this card.

What do you people think? Decent?

Comments are welcomed! :welcome:

My card OC'd very similarly to that one, though it's an R360 core. I did a volt mod using SMD grabbers for the IC legs to eliminate having to solder anything onto the card, and it was actually pretty easy. My gains weren't as good as I would have liked though. The core maxed out at 435 @ 1.69v (stock), and hit 455 @ 1.75v. Beyond that, even up to 1.8v, I got maybe 5MHz or so, so it's pretty much maxed out. I'm on watercooling too, and the card never even felt warm to the touch, so I know it's not heat.

kudos.

Another thought about voltmodding. Your card should respond a little better to voltage, as it's on the R350 core. There's really no way to know without giving it a shot. I'm happy with a 20MHz gain and a little extra voltage over here.

That's pretty decent, because my card did exactly the same clocks. (It was R360 though :))

Thanks for the feedback. What's the difference between my R350 and others (R360)?

I think I am going to pass on the volt modding. I just don't see how it's going to make a dramatic difference from here on out. Going to keep it cool and safe. :cool:

Have to give major props to the Koolance water cooling kit. It's a remarkable kit! So clean and easy compared to custom DIY water cooling setups.
