Currently using a Z170A MSI M5 board. Guess it's back to MC to try a Z270 board.
I used the Z170A M5 for my two linux/470/570 rigs. Works flawlessly. But for VEGA was reading it's really finniky with boards. So I broke down and bought the slitghty more expensive (even more so on Amazon) Asrock H110 Pro+ board. I only need 4 of the 13 slots, but people reporting good results for Vega (even though the reviews people complain about it a lot).
Thank you for this. It's available same day shipping for me. It'll be here this afternoon.
In the meantime I grabbed THREE different boards from MC to try them out as well.
Expecting my Onda D1800 any day now, can't wait to start inflicting myself the pain of trying to get 6 Vegas to hash...
Any time I add 6th GPU to a ASROCK Z270 Killer/SLI, windows BSOD. +4g, -audio, -wifi, -serial, -pptp... Not enough PCI lanes I guess. I even tried to shut down unused usb ports.
Going to try PCI-e switch, and also M2/riser to see if I can bogart those pci lanes.
