Crossfire with 3DMark06 (one card not getting 100%)

post #1 of 7
Thread Starter 
I have 2x XFX HD6850 in Crossfire and one thing I noticed in GPU-Z after I ran a few runs in 3DMark06 is that the first card got up to 99% load and max temp was 62c. However, the second card only got up to 25% load and 40c max temp.

Can someone explain this to me?
I'm only using 1 monitor. 3DMark06 score was 21,something with AMD Phenom II 955 @4Ghz and both cards at 850Mhz/1175Mhz.

p.s. I tried this with 3DMarkVantage and almost same results.

Throttling?

What's the usage like during the first run?

It's the same.
I'm using an Asus Crosshair IV motherboard with 2 PCIe X16 lanes.
Both cards are OC'd through Catalyst Control Center.

Which tests in 06, GT or HD runs?

And you're absolutely sure both slots are running at 16x?

And yes I'm sure.

Kill gpu-z, run afterburner in the background to monitor usage.
