ok so a guy i know has just built a super computer with a hd 5970 2gb and he plays wow spread over 3 monitors, win 7 only detects 1GB and oddly enough direct X diagnostic (dxdiag) only detects 750mb. all programs, (windows, pc wizard, ati software, dxdiag) do not mention anything about a secondary gpu. to sum up his frame rate is awful for what he has and i believe its due to wow being in a massive resolution and windows only allocating it the 1gb it detects from the card. any suggestions as to a solution?

rundown on his rig: 1000w psu
ati hd 5970 2gb
8gb ddr3
phenom II

Download and install CPU-Z and GPU-Z and see if they give you the correct values.
If they don't show the correct amount of video RAM I would contact the board manufacturer's support. Try installing the CCC 10.11 drivers. I've had nothing but problems with the 10.12 version.
I don't have a 5970, I have a Sapphire HD 5870 2 GB and the above software does recognize 2 GB of video RAM. The HD 5970, being a dual GPU, is a totally different animal and is why I think you should ask the manufacturer for advice. This might be common with this board or it might be defective.
