Looks like you have PSU problem. But I can be wrong.
First of all, if you cannot get the signal to monitor then check the bios settings setup for an intended card.
Or you could change the HDMI to DVI adapter because I have the same motherboard and there are no problems with that.
Problem with the "Display driver stopped responding" cloud with the overclocked video card.
Cloud you draw a diagram of your wiring and add some information about devices you have?
What kind of synchronizer do you have?
It had signal for like 3 seconds, after a few restarts, one time. It was a new DVI-D to HDMI adapter, also cheap, so could be faulty or something. Try to find also a better one.
About the overclock: core clock was down to 1150 from 1340 and only memory clock a bit up, to around 2100. Since 2 days I'm testing also with a bit of less voltage for cards,
so running Claymore with 900 mV in the parameters.
About devices:
1 x Intel Celeron
1 X 4 GB DDR4
1 X Biostar TB 250 BTC
2 X 700 Thermaltake PSU
1 x Wazney synchronizer (but I noticed that sometimes after some a bit more forced shutdowns, the second PSU will not start, not sure if synchronizer has something to do with this)
6 x Wazney (I think) Risers
1 x Biostar 120 SSD
6 X RX 580 PULSE
About wires:
Before: 1 SATA cable for 3 x riser and 1 X SDD on one PSU and 1 SATA cable for 3 x riser. And since each PSU has only 2 PCIE connection with split wires, 2 GPU needed to be on same wire. (Also had melting issues with too many things on one SATA cable)
Now: 1 SATA cable for 2 x riser and 1 SATA cable for 1 x riser and on the other PSU 1 SATA cable for 2 x riser and 1 SATA cable for 1 x riser and 1 x SSD. GPUs still connected the same way.
Since Thermaltake PSU has some piece of software that can read some information from PSU (has USB cable connected from PSU to MOBO) I was able to see the some details there.
Yesterday I had only 3 GPUs + risers on one PSU ( reporing almost 400 W ) and MOBO + CPU + SSD on the other (reporting up to 50 W) and:
- for 5 V the PSU software reported 5.3 V
- one of the GPUs hanged at some point and Claymore tried to do a restart.
Before adding the 3rd GPU, while I was away from the rig, it restarted itself and I saw in Windows that it was an unexpected shutdown. :/
