Just got my second 2900xt today. GPU-Z won't read the overclock at all on either card. I'm running the HR-03 at 858/1153 and the other 803/1140 (stock cooler). GPU-Z reports both as stock even though I know there overclocked.

I've had some time to play with the latest BIOS and it's let me run at 3.2 Ghz 356 X 9. Only 3dmark tested so far although xp has been running without problems for the last couple of hours but I'm going to leave it fold overnight to test for stability.

Managed to hit 17181 in 3dMark with 2 x 2900xt 1gb with the overclock above :
