dear all,
started of with 1 290x and everything worked fine, second one aswell. so added third one got to mining, then tried to enlarge the miner window and got a BLACK screen, rebooted but now no signal and i cant get it back. Tried to reset switch cables but nothing. When i turn system on, cpu fan is running as are all three card fans..
disconnected the 3th card and tried 2 again, now this sometimes works and sometimes doesn't. I installed teamviewer and there i can see the rig isn't coming online every time. I tried switching PCI ports with no result. For all the cards i use powered riser cables 1x > 16x. Also tried to power directly through mobo via the 2 molex but this doesn't work either.
MOBO: h81 pro btc
pentium g3320
r9 290x
PSU: enermax 1350W
2x 4gb ddr3
60gb ssd
When running the first card I got an error in cgminer concerning the memory since there was only 1x 4 gb ddr2 inside, could this problem have to do with the memory or maybe PSU?
Anything would be welcome, thank you
