Constant, constant troubleshooting.  Can't get anything stable.  Rig will run fine for hours and then shutdown.  When trying to restart, Claymore miner will get to the OpenCL Pool/Solo and crash and burn before generating the DAGs.  I isolated the trouble card by using -di 0.  So it's failing on GPU0 when trying to initialize.  I took all risers out of the mix and plugged card straight into PCI slot.  Card shows up in device manager, appears working fine, and just wont initialize in the miner.  I flashed back to original bios and still no joy.  Sensors look okay in GPUZ.  Do I have a brick?
