Radeon 9800 Pro LE o/c'ed too far?

[marinlicina]

Ok, I have a Radeon 9800 Pro LE (basically a 128-bit version of the R300 core). It normally runs 350/350 (core/ram). I jacked off the original heatsink, replaced it with a Arctic Cooling VGA Silencer and here we go, overclockers heaven. At least, I thought so.

I never used an ATi Card before, so forgive my puny ignorance, but i screwed up bad. :evil:

Using the Omega Drivers (newest), I pushed the mem a bit too far, and now the card won't boot. My mobo says, when I attempt to boot: 'g system failed'. I keep resetting but get the same crap over and over again. For those not familiar with the Omega system, it doesn't o/c the card directly (like nVidia), but you supply the clock speeds that the card should boot with the next time the pc is started up.

Can anyone tell me a way to restore the original frequencies, because the card now boots with mem speeds to high.

Thanks to all who help an ATi n00b 😱

Boot into safe mode and uninstall the video drivers. Follow that up with a good scrubbing with Driver Cleaner. That should purge your system of the bad clock speed settings.

Thanks, it at least works.

But does this mean that I will always have to uninstall when I push the clock 1 MhZ too far?

Is there an easier way?

well 1mhz too far will just give you artifacts, so you shouldn't have any trouble boothing like that. however, if you decide to crank it to absurd speeds again you will have to uninstall the drivers again.

If I'm not mistaken, the Omega drivers use Radclocker to give you the ability to overclock your card. I use Radclocker with my standard Catalyst drivers to overclock my card. It's a nice utility to use.

When you are setting up your overclock, before you tell the utility to set your card to boot at whatever given speed you are trying out, play some heavy 3D games for a few hours to test things out. If it works, then set the BIOS to boot at that speed.
