I have the below motherboard, cpu & psu
P8Z77-V LX ASUSTeK COMPUTER INC. (0401 02/14/2012)
4 × Intel(R) Core™ i5-2400 CPU @ 3.10GHz AES
2000w Mining PSU
I have two “4 Port PCIe Riser Adapter Board” with 5 gpus. When I attached the 6th GPU the system won’t start, I have swapped the gpus around to see if one of them was faulty but they all work fine it’s just when all 6 are together.
When I have only 5gpus running I have entered the bios setting on startup to see if there is anything disabled and everything looks like it’s enabled.
Do some motherboards have a limit on the number of gpus you can have installed?
Thanks for reading, if you can help that would be greatly appreciated
