So Ive got a multi GPU setup, running on Asus P8Z68-V PRO + 2500k. Currently its got two AMD 380s and a 980ti. One of the 380 is on the top PCI-e slot and another one is on the last PCI-e slot using a USB riser. The 980ti is on the second PCI-e slot.
The first 380 and 980ti work perfectly using genoils, on two seperate instances of ethminer, but the moment Ive put in the second 380 using a USB riser my PC freezes a lot. Im currently testing the 380s without the 980ti mining over the next few hours to see if I can mine without anything crashing.
Ill also try various opencl local and global settings. Is it possible that the opencl local and global settings are causing my computer to freeze?
Do you think it could be my PCI-e slots? Should I try forcing all the cards into PCI-e 1x to see if that might help?
Appreciate any help.
