x1950xtx and crossfire problems

post #1 of 7
Thread Starter 
OK, I have an odd problem and it's killing me. I just got my x1950xtx back from RMA and plugged it into the first PCI-E slot to test it out alone (removing the crossfire edition card that was there.) Anyway, it does the same thing as the crossfire card...
It automatically puts the VPU Clock at 506MHz and the Memory clock at 594. They are supposed to be at 648 and 999, respectively. Does anyone have any experience with this? One workaround was to use ATItool, but I'd rather a permanent solution and not a workaround.

Thanks.

The lower clocks are 2d clocks.

The 3d clocks (648/999) kick in when a 3D app starts.

I use Ati Tool to create a profile that loads on startup. Whenever I log into windows it loads 735/2142, appropriate voltages and 100% fan.

BTW, that Opty must be one hell of a bottleneck! I had an X2 4400 and when I got my C2D I noticed a huge gain in GPU power

OK, so this is normal and I shouldn't worry? Thanks for the quick reply.

I have the Opty clocked to 2.8Ghz... you think that's a huge bottleneck still? I just don't want to switch technologies right now... the cards were expensive enough.

Yeah its normal. Its to save power when at desktop doing nothing.

Create a profile and it will auto load that profile on startup.

I think its a bottleneck for sure. I only had one x1950xtx with my x2 400 and it wasn't until i got the C2D that i realised the old cpu was bottlenecking it. I noticed big gains in FPS in games and scores in benchmarks.

I'm sure having two XTX's through a 2.8 ghz Opty will be a bottleneck, not a small one either.

Gotcha, and thanks for all of the advice. I've been kicking around the idea of just returning the CF card... it's not super necessary, and if my CPU can't even handle it's full power, maybe I'll just wait for a full upgrade, either to C2d or AMD's next gen stuff.

It's not unnecessary. You will still see a benefit with the 2 cards but a 3.5 ghz oc'd C2D will unleash those puppies

Dual core optys at 2.8ghz a bottleneck are you insane? C2Ds are great sure but thats far from any bottleneck except in CPU limited situations (800x600 resolution or lower, CPU dependent game).

90% of all games right now are GPU limited, the speed increase you saw from going C2D is just the faster CPU doesn't affect the graphics.
