Radeon 9000 Pro AGP Flashing

So after my card warms up it starts to artifact as well - a sort of fine texture of yellow and blue dots over the whole screen. Very odd.

What happens if you modify the ROM to down clock the VRAM speed a little?

The ROM I’ve used sets the VRAM to 250MHz, and the VRAM is rated at 3.6ns/275MHz. So it’s already clocked conservatively. Don’t you think it’s more likely that one of the chips is bad?

I didn't know how your VRAM was rated sorry, if it is faster than needed it shouldn't be that.

Although my current video card project has some VRAM that is not performing at its rated speed.
