Title: No signal from PCIe risers Post by: Lumining on November 03, 2017, 03:27:14 PM Hi,
I made a Cmos reset of my motherboard (AsRock H81 Pro BTC) and since then, my miner doesn't recognize the GPU's anymore. I changed PCIe speed to Gen1 and tried with 1 riser connected to the x16 slot. The miner did power up but there was no signal on the screen, mouse and keyboard were not working. Without a riser plugged in, the PC works perfectly fine and boots without problems. How can I fix this problem?

Try plugging the monitor into a card or the onboard graphics port.

Thank you so much, I could've found this solution on my own, but with your help the problem got solved in less than 10min, many thanks again! I set Gen1 in the mobo settings for PCIe speed, is there anything else I should set in the mobo bios settings?

If all of your GPU's is now working with your current setup that would be fine, my advice is, just don't fix thing that ain't broke.

I would setup the primary graphics card to be the onboard in the BIOS so after a restart only the motherboard's hdmi output will work - like it was the case before the reset.
