Hello,
i have got myself a new sager np8180 with dual 6990 and only one gpu can be used (i checked through msi afterburner) even through that gpu the frame rate is low.

Hi Hammad :) 

Here are a few things I would do.

Update the motherboard to the latest bios. If its already up to date, manually clear the CMOS/bios then test one 6990 at a time to be sure one is not faulty.

What make/model is your power supply and what temperatures are you reading ?

edit.. my bad lol.. just noticed the 'm' hahah..

Check to see that you are using the latest drivers and bios updates for the motherboard and gpus.

What does tech support say ?

300W PSU is nowhere near enough. 850W minimum for two 6990's.
