Crossfire with 2 Radeon 4890's benchmarking really low

I just ran 3D Mark 06 on my PC, and it seems like it is benchmarking really low. Here are the main specs of my machine. I did not overclock anything.

Windows 7 64-bit

Core i7 920
6GB DDR3 1600
2 Radeon 4890's in Crossfire

I am only getting a score of 17,697 marks. This is lower than a lot of scores with one card.

CCC detects both adapters (one as primary, and the other as linked). GPU-Z says "ATI Crossfire Enabled (2 GPUs).

Any ideas what the issue could be?

If you didn't overclock your CPU the score is right on the money.
If you did overclock the CPU, I don't know, that score is not possible with a single ATI 4890.

You may find that 3DMark does not utilize CF and thats why you get better scores with a single card.
