I have heard of similar problems with other miners.
You will be much better off with ONE power unit only (such a nice Corsair or EVGA 1000 W unit). Splitting the power across two units is not really a good idea and you may encounter problems.
Also, I would recommend that you upgrade the OS to Windows 10.
Topic: Limited maximum GPUs? (Read 174 times)
Hello fellow miners,
I've set up a mining rig using the following hardware:
ASUS Prima Z270-P motherboard
Intel Pentium G4400 CPU
4GB RAM
4 x Geforce 1080 Ti GPUs
Seasonic M12II EVO 520w to power 2 of the GPUs
Seasonic M12II EVO 620w to power another 2 GPUs and the motherboard + PCIe risers + SSD
Windows 7
Now, I connected all 4 GPUs, but windows can only detect 3 of them. By playing around a bit and plugging/unplugging cables, I noticed that when the 4th GPU is detected, the other 3 are not. Whatever combination I try, either 1 ore 3 GPUs are detected. Can't make it work with 4.
Any idea why? I would doubt that it's a power issue, because the motherboard alone without any GPUs uses around 80 watts of electricity. Nevertheless, I'd try to underclock them a bit to ~200w, if somebody could give me a hint how to do that with PNY cards.
Tanks in advance!
