Hi,
I am trying to make my first gpu rig with 6 gpu's, with ethos as OS..
I have:
Ethos 1.2.9
Asrock H81 Pro BTC r2.0 Motherboard
6 Sata to Molex powered PCIE Risers
1x ecopower ii tooq 500W Power supply for mobo, ssd and the risers
6 x gtx 1080 GPU (3x Gainward and 3 Gigabyte)
and a 1200W Server power supply..
the tooq ecopower ii has only 4 Sata cables and 2 molex.. the only working config is to use.. 2 sata -> two gpu's, 1 gpu directly on molex from psu and 1 ssd and one gpu on the other sata cable..
When i try to use more than 4 cards.. it crashes on mining start.. somethimes it doesnt even detect the 5th card..
i tried different risers and pcie slots, i tried also win 10, and also tried sata Y Cables (made the thing worse.. didn't even work with 4 cards anymore or crashed after few hours), tried different bios (1.3B)
with no success at all
what can i try next?
shouldn't be a 500W Suplly enough for 6 risers, mobo and ssd?? or should i try a 650/750W supply??
currently i have no ideas anymore..
thanks for any help
