Hello, I just had to upgrade my mining rig to windows 10 because windows 7 can only have 5 physical cards in it. I was getting to thinking, I'm using a ASROCK H97 anniversary motherboard, and my current setup is one r9 295x2, one r9 290x, and 3 r9 290's. I have another R9 295x2 that I'm running for mining on a separate machine, because I can't figure out how to get the motherboard to accept all of them (6 physical cards, 8 gpu cores) Does anyone know how to do this?
More concerned with my motherboard, I think I tried to boot in the past, and I don't think it will boot if it detects more than 6 gpu's connected. I was in quite a panic yesterday, because I didn't know that windows 7 has a 5 card limit, and I thought one of my GPU's was broken.
Maybe there is a BIOS mod for my motherboard so I can use more than 6 gpu cores.....
It didn't work with my ASROCK BTC board. Max is 6 GPUs, if one of them is dual core, then max is 5 physical GPUs. It will get detected in Windows but once you start mining it will become very unstable.
Windows 7 doesnt have a 5 card limit.. who told you those lies? LOL
My old Windows 7 rigs have run in the past with 6 single GPU cards (6 GPU total in device manager) and 4 dual GPU cards (8 GPU total in device manager) without any issues at all. You just have to run the 6xGPU mod and you can have up to 8 GPUs working without any problems.. Of course, your PSUs have to have enough power for all the cards, and your mainboard has to have enough working PCI Express slots to get it all running together.

Without doing any mods, Windows 7 can only run 5 cards. Any additional cards I put in would give error code 43. I'm asking how to get my motherboard to boot up with 8 GPUS (6 physical cards, 6 pci slots on my motherboard) Whenever I try to boot up, it doesn't even get to the operating screen boot logo. Anyone here know of a way to mod my Motherboard or BIOS for my motherboard, so that I can mine with 8 gpu's on 6 physical cards?

Maybe it's an issue with windows 10 freezing on me

I have a 7GPU setup running on a H81 BTC consisting of 1x reference Sapphire 290x, 4 MSI Gaming 4G 290X and 1 MSI 295X2. Using 3 PSUs, runs stable...

The point is: "in the past". And that's not a lie, win7 has a limit, and solutions also, which wouldn't work with newer amd drivers.
I am confused. You say that you are running 8 GPUs and have only 6 GPUs in the pic. and then talk about 7 GPUs and only have 6 GPUs in the pic. How is this 8 GPUs?

A 295X2 is Dual core 290X operating in 1 slot
Next Story will be a 8 Slot setup on a MSI Gaming 5 Using this:
I'm running 7 cards on same board with a port splitter. 6 rx 480 ref and 1 290x, trick was to not allow amd driver to install with software, but to download it extract the installer then go to device manager and right click the gpu and point update driver by pointing it to the extracted folder. I did one gpu, shutdown, then plugged in all but the 290x and repeated, after the screen flashed 5 times I powered off and plugged in 290x and then did the same thing. All work and all show fine. I just wish I could add the 8th gpu, when I do the system wont boot(black screen), not sure why. Oh also make sure in bios you set pci to version 2 or version 1. that was a key point, I just set mine to version 1 never tried 2.
afaik 8th gpu wont be detected by windows whatever u do. I have seen people posting their trials but never seen a succesful story. Even the mobo it self dsnt recognise more than 7 gpus or graphical processors in my mobo which is msi z97gaming 5. U can see my thread about this.

There are others who already posted with 8gpu succesfully only if they are 3gb cards. NOT the 4gb ones. There must be some relation to total GB of memory of the cards which makes it not possible to be detected by either mobo or windows. Let us know if you have success with 8x 4gb cards being detected. that would be a new invention
@bhanu545 8 cards is the driver maximum for AMD cards... you can absolutely run 8x 4Gb cards, and has been done before. Total VRAM isn't relevent. What is relevent is motherboard support and a CPU with enough pci lanes.

true 8 cards with 3GB RAM works fine or 4 dual gpu (HD7990), but 8x graphic crads with 4+GB not work.

Most cpu supports 16 pcie lanes, most motherboards dsnt have more than 7 pcie slots. Also heard win 10 dsnt recognize more than 7-8gpus as posted by other members. Running 8 cards is a trick n luck now as somebody posted using M2 to pcie adapter. But no real world proofs that will work showing 8x4gb gpus working.

Is there a motherboard out there that can support 8 cards out of the box?

There's dual gpu video cards, like r9 295. One card to one slot, but two gpu device for the system.

I have 7xRx 480 works fine, but 8x Rx 480 not started, black screen
