Good evening,
I have a gaming computer that I am currently allocating to mining. My cascade cooler broke down so i figured what the hell.
MSI X99 Godlike Carbon
6900k
RX 480 Powercolor Red devils
WINDOWS 10
Now i currently have the BIOS updated to GEN1 PCI and a latency of 96, however I can still only get 4 GPUs to show up in device manager and one under “unknown device”
The board explorer in BIOS does in fact show 5 “ATI technologies” via the use of the risers and all slots highlighted.
Any thoughts to make my rig see all 5 gpus for the time being?
I have actual rigs coming in (I HOPE) still waiting on a vendor to ship them, but thats another story.
Any help would be great
You may need a jumper pin if the GPU that is not showing is one plugged into a 16x. Determine which slot is not displaying or if the problem is with the 5th, regardless of slot.

About halfway down.

So i think it might be a riser board its either that or its a windows issue.
I swapped things around 45 different ways. All slots work with risers no jumper pin needed, plus on this board they are shielded anyways.
So i think its a just a windows issue. didnt have time to check the only riser possibly malfunctioning, i will that tomorrow. But has anyone had any issues with windows 10 not recognizing 5 -7 gpus? what was the fix?
I know win 7 had a mod, but i thought Win 10 was good to go on this
you could always call MSI and ask
i dont have that board running atm but can’t remenber if it has a setting for pcie speed? like 16x, 16x16x, 16x16x8x? if so maybe try the lowest setting?
