It might be more of a help to get the rest of the setup though. Many people are having issues geting 6x 290X working, where as 6x 7950 is easy. So its not so much a motherboard problem, as it is a software or BIOS ram problem.

Actually in the case of the MSI Z77A-G45 it's a hardware limitation, confirmed by MSI (check details in the link posted next to the board's name).

Well i dont think windows even supports more than 6 GPUs so buying a 7 pcie slot mobo would be a waste.

Currently doing 3 Sapphire R9 290 Tri-X on all 16x slots due to lack of risers with no problem. Hope to get some within a week.

Good luck burning the board. Stop trying to save every penny on this. 5 to 6 card builds are best. Thanks for the list though.

Keep those cards cooled well. Without risers there is no room for fresh air, the cards will not last very long.

The board won't last long either.

Currently each card seems to pull a max of 25-30W per PCIe out of the board + 240-250W out of the 6/8 pin power connectors, measured at the wall. Temps are 75-85 while mining at about 810 kh/s (underclocked core clock to 900/1250).

Burninj, on the z87 g45, did you have to short any of the pins in the PCI-e slots to get all 7 GPUs to work/be recognized?
