Have 4 of these, the AMI aptio bios is ridiculously configurable however its as if this motherboard resources is not mapped correctly.
First off, using 560 2gb (non 6-pin powered) fks up everything if you use 580 or 570, many of those 560 won't start.
PCIE 1 to 4, works PERECTLY, but once you use the gigabytes 560 2gb (non powered) in ANY slot (1 to 4 or normal slots) again , similar issue, gpus randomly not startring.
CPU temp sensor is -70 celsuis GOOD luck burning your celeron/pentium stock fan..... it refuses any power management.... (4 motherboards all of them with the same sensor not working) , if you have a solution let me know.
Last, 2 of the motherboards burnt by a USB device short (i fiddle alot with these and with an asus b250 mining expert) all of the 3 had the same thing (probably the chinese 1800 psu, however i tend to experiment/restart/ force shut alot)
Not sure if thats a fuse or what.... but, 3 motherboards dead is too much for any ROI
I have a good multimeter and a soldering sert but really tired with timings custom optimization and other life stuff.
Hope these info helps.
Only solution to run 560 on this motherboard when you have non powered ones, is to have ALL the GPUs 560 of various types.
Otherwise, motherboard works and PCIE settings in an updated bios i barely got from the ALiexpress vendor are huge.
