Does anyone testing to run more then 7 RX 4xx gpus on B250/H270/Z270 motherboards?
no 7 is the basic limit.
I read on this group people that run 8 with z270 chip, with m2 to pcie or usb extender
yep but that is not a basic setup.
Some have done up to 8 with pcie splitter
But 7 is the basic limit.
And most will tell 5 or 6 makes more sense.
