Sounds like a power issue to me.
I have three 280x in one machine with a Seasonic bad ass 400 dollar 1250 watt PSU and it cannot max all three out.
Topic: System freezes when mining with more then one GPU (Read 872 times)
Is it possible your power supply isn't powerful enough for both at the same time?
I'm having a similar issue. My rig runs fine with 2x GPUs but when I install the second card sgminer recognizes all 4 GPUs (one 7990 is seen as two GPUs) runs for about 30 seconds with the GPU #0 showing 0.0KH/s before it freezes.
Hello fellows!
I hope to move this to the support forum when i'm "trusted"^^
I have a severe Problem with mining.
I use CGminer and whenever i use both of my R9 280X in any way at the same it will mine for 1-5 seconds unti my system freezse completly. I know the GPUs aren't working while this happens because i only use 150W while it is frozen.
I'm using a brand new 64-bit win7 ultimate with ATI Catalyst Suite 13.12 and cgminer-3.7.2-windows.
I'm starting just by double clicking on the miner, since i have it all configured in the cgminer.conf. I get the same error, when i use a *.bat with the configs in it.
My cgminer.conf
When i add a "device" : "0" or "device" : "1" everything works fine with just the one GPU in use, i also tried running 2 instances of cgminer--> no sucess
My System + Hardware:
I would really appreciate any help!
PS: I'm sorry if there are any grammar or spelling mistakes. It's not my first language have mercy
But if you finde a mistake feel free to shoot it!
