x800GTO^2 Overclocking.

[Borgschulze]

Just need to confirm something, or even get help with it.

I recently aqquired a Maze 4 GPU block for my Birthday, and I love it, never over 40c load.. I used to idle at higher than that.

But now I want to overclock this video card more.

The problem is... it doesn't artifact in ATiTool, but instead it locks up...

I had it all the way up to 659mhz on the Core and it locked up, and 651mhz on the Memory, which also locked it up.

I did Core and Memory in seperate runs.

Is this a Voltage issue? Or can a GPU BIOS flash help this?

This card seems like a champ to me, it gets 590mhz Core and 590mhz Memory Quake 4 stable, probably one of the harshest games on a Video Card, and that's with the stock cooler hitting nearly 70c.

Thanks for reading my post, any help is appreciated.

Played an hour of Quake 4 at 621/621 with zero artifacts or lockups.

did you unlock the pipes?
that will make the most significant performance differnce then a couple mhz..

Of course, I laugh at the fool who doesn't.

And gaining 220mhz on the Core of a video card is quite a difference.
