if you are talking about wattman maybe you are undervolting..
and if yes, maybe you are goin "too low"!
Try to rise some mV the GPU voltage CORE/MEM
But i'm not undervolting.. I keep default setting. Same setting that in Win7 work. I think something on Win10, but I dont know what other way try.
if you are able to build a log with some error, why you don't copy and paste some lines of error here...
Another TIP: check your event view... maybe there are some info there.
Tried but nothing, continue to crash...
No PC reboot, only grey screen, freezing.
I tested raisers and gpu on another PC with same Win10Pro 64, and all work fine.
Now i'm thinking about Asrock H81 Pro BTC configuration, because is the only thing different.
I have read a lot of different opinions on powered raisers and extra power on 2 molex on that mobo.
May be that?
I'm trying only with 2 cards. Have I to plug in molex on mobo or not if I have powered raisers?
What you think other?
Thanks
