Primary 6950 stuck at 500 mhz - ideas?

post #1 of 3
Thread Starter 
Well here's what I've figured out. MSI Afterburner reports card 1 as card 2 and vice versa.

So basically, my primary card is stuck at 500mhz at all times. Any ideas? This happens regardless of whether I'm running CF. I've only got one of my displays hooked up right now, the 30".

Second card downclocks to 250mhz and ramps up to proper 3D clocks in CF mode.

Dude, AB doesn't read the cards properly.

Actually AB is reading it properly. Only thing it messes up is which card is which.

First card was stuck at 500 mhz. Confirmed with GPU-Z. Confirmed with ****ty performance.

I restarted the system and that seems to have fixed the problem...for now. Seems like a driver issue.

I hope we get some proper voltage control and better OC headroom on these things (without flashing to 6970 BIOS and risking the health of the RAM by overvolting that specifically).

My temps on water are just silly (~40 C load). On my heavily overvolted 470s, temps were 60C at max load.
