I have a rig 4 x 7990 (8 cores total), working with win 7 64 bit.
damnnn thats like 5ghs!!!

rumor has it that 4 7990 dual gpu will work, so thats 8 gpu, but no proof out yet
I have herd the same thing, I don't think anyone is taking the risk of buying four of these cards just to see if it works.
I also heard that it's mainly win OS that has the multi GPU driver problem, Linux is easier to find and work with the hardware, But it is still entirely MOBO dependent.
i run 8 gpu on many of my rigs, but they are all 5k series. 7k are known to have driver and OS related limit of 4-6 gpu depending on driver revision and OS (rumor has it that 4 7990 dual gpu will work, so thats 8 gpu, but no proof out yet).
if you have missing gpus in your device manager, you either screwed up your riser, or forgot to short pci-e presence pins, or some sort of hardware limit with something to do with so many devices per set of pci-e slots (try different slots)
mobo msi z77a-g45

Is it possible to run 8 GPUs (not cards but GPUs) on the same motherboard using Windows 7 Home 32bit?
I'm running 4 cards already: 3x5970 and 1x5830, so it is 7 GPUs total on the same motherboard and I'm wondering if anybody was able to run 4 cards with dual GPU or 3 dual GPU cards and 2 single GPU cards on the same machine.
Assume that power requirement is not an issue. (I'm running 2 PSUs 1200W+650W)
I'm already hitting a limit with my 7 GPUs as only certain combinations of PCIx slots would get the cards recognized and configured.
