Default Reverting an overclock

Okay, I've been getting the amdkmdap error for some time now. I have about 20 pages of google results with purple links and no answers. I've gotten help from half a dozen techs with no answers.

I've done all the obvious things, like updating the video driver etc etc blah blah blah. Anything you could find on google, I've done it.

This is what I've got so far:

Disabling windows aero theme makes the error occur less frequently.
The GPU runs at 68*c when under heavy load.
The GPU runs at 55*c when under heavy load, but with the side of the tower taken off. The error occurs about a third as often when the side is off, but 55 is not a dangerous temperature and it still happens a few times a day.

What I recently found out is that the video card I bought was overclocked. This is it.


I'm fairly certain that if I underclocked it back to what it was originally supposed to be, it would stop giving me problems. I assume doing so will void the warranty though? I'm not sure what to do. In any case, here's what's going on:


Tell me what I should do. I need to be babied so that I'm certain it's done right.

ps. Yes I know I haven't listed my other specs or the steps I've taken so far because people will just give me answers that I already know/already tried.

I am never getting an ati card again.


^ That is my PSU btw, if that's relevant.

EDIT: I Think even more important than below, I should ask if your card is still under warranty? If the card is malfunctioning, it might be a good idea to file for an RMA on it before messing with the clocks which may not solve the problem anyways.

Have you used an application called ATi Tool before? Or perhaps one called RivaTuner?

I am asking this to see if these have already been tried from your trials with google results.

Changing the clock speed does not void the warranty like I had thought. I spoke to powercolor customer service, they told me to go ahead and unlock ati overdrive in catalyst and turn it down by 50.

Seems to be working fine now.

I knew how to do it, but I didn't know how much I should turn it down by because I didn't know what the cards natural speed is.
