I want to buy new version MSI Z270 Gaming Pro Carbon or Asus Prime Z270-A.
Do you think that it will be working with all PCIE slots (6/7 GPUs)?
I've got asus z270-a. 7 gpu works fine
What BIOS settings? How much RAM in your GPUs?
I have same MB and can only run 4 GPUs
pc ram - 4gb
7 x rx480 8gb
I dont know what exactly helped to run 7 gpu, but here what I changed:
above 4g decoding - enabled
pcie switch to gen 1
dmi max link speed switch to gen1
disable all sata, which is not used
disable all usb, with is not used
