I don't trust GPU-Z, it never reads my clocks correctly.
Open CCC and check for 2 cores.

What do you mean it won't let you do anything?
Is overdrive unlocked, can you move the sliders?
Have you monitored the core speeds while gaming?

What motherboard do you have?

i have the K9A2 motherboard, i unlocked it, i can move the sliders but it wont let me enable the Crossfire of the cores to make it work for one monitor, my card is using 1 core for 1 monitor, so how to i make it use 2 cores for 1 monitor, like look at rusty 100's post his pic of GPU-Z says ATI Crossfire enabled but he is only using 1 3870 x2 card and mine says disabled, and the gaming core does kick out of 2d mode into 3d that i know for a fact
post #8 of 11
I had kinda the same issue with my 2900XTs. One card would ramp up in 3D mode, fan speed ,core speed and temps. The other one nothing would change. I had to RAM that one. Seemed the ATI rep on the phone was very interested in the issue. Course this was like about 3 weeks after they came out to.

As far as the GPU-Z not seeng Corssfire enabled, on my PC it states the its disabled also. Its bug with the program I think. Also my system in 3DMark does not show Crossfire enabled either, under "Linked Adapters"

Try updating your mobo bios, Chaos Prime had issues that a bios upgrade fixed.
