H81 PRO BTC 2.0 Windows 10 error 12

how much ram you have ? And to what amount you increased the virtual memory ?

I having trouble to understand you power connection. Could you please explain once again ?

So basically, 2 things i recommended to you.

1. Activate iGPU and Onboard Graphics as primary display adapter - and connect your monitor or whatever to the board not the cards. It slightly reduce load while mining and is better to investigate in errors.

2. So i realy guess, its up to the CPU Or RAM it doesn't have enough capacity. I have this board too in one of my Rigs with 2x 8GB RAM and i7-4770 cpu.

Also: I say, you should rethink your power. 220W is round about a system (please note that primary all connections to the MoBo needs to come from the 1. PSU). 75W per Riser (Sata is crap for it) and another 75W for the Cards. Use if possible 6 PIN directly from PSU to risers and also connect directly from you PSU to Card the 6+2. Please note that the connectors to the MoBo only has to come from 1 PSU never splitt it. An dont forget the molex on the Mainboard, thats extra power for the PCIe's

And by the way: The Board is made for Mining its supporting 6 GPUs from Stock, without 4G decoding and also no need to change the Generation of the ports leave it on auto.
