Asus prime z270-p ???
If any one heve working rig with 13 -14 or more GPUs on asus prime z270-p please upload bios profil file .CMO
General instructions for this motherboard is 4g enabled. 13-14 gpu setups really depend on m2 extenders or pcie splitters.
BIOSTAR BTC 250 PRO (12 GPU) does not work with PCIe splitters.
Tested and confirmed by me…
How many gpu can you run with the z270-p you have?
