Hi guys,

I can't make my MSI 970A-G43 work with 4x Sapphire 7950. I've tried varies of risers 1x-1x and 1x-16x and Windows 7 x64 doesn't see more than 2 GPUs.

I turned all of the unnecessary gear in bios. I am using 1600W PSU. I also tried to change PCI latency, empower the risers and I checked the system with Sempron 145 and Athlon x2 I am using now - nothing has helped, W7 sees only 2 GPUs.

Is it possible to make this mobo work with more than 2 GPUs?

Best regards,
LG
