mining GPU not active

[d0n4ald]

I have a 1080ti on riser . not mining anything yet, just booted up and after a few mins, sometimes 20-30 mins, the GPU temperature drops to zero and settings are grayed out on MSI afterburner - like it is detected, but somehow it's off. I swapped out with a different GPU (1070ti) and different risers and it does the same. this is on a fresh install of windows pro 10 build 1903. Geforce drivers 436.30 which is the latest. i uninstalled and installed drivers multiple times.

what could be causing the issue?

This belongs in altcoins I asked mods to move it.

But let’s try to troubleshoot it.

When you swapped risers did you swap the riser’s usb cord?

Did you try different pcie ports with the risers?

What is the mobo make and model?

yep i swapped usb cords as well. tried the other 4 different pci-e slots . THe risers were not used for a year - would that cause risers to go bad? all hardware was working and mining before for 6 months straight with no issues. The GPU's definately work as i plug them directly into the mobo pci-e 3x16 slot. the difference is i installed a new ssd and fresh windows 10 pro install. the GPU is detected in device manager,afterburner, GPU-Z, HW monitor. the weird thing is sometimes it appears fine, but 15 mins or 30 mins later (there doesnt appear to be any pattern as to when it turns off) its liek the GPU goes into sleep mode - 0% TDP, 0C temp, afterburner settings grayed out and unadjustable. so i am suspecting windows 10 pro or perhaps a bios setting. i may do a fresh install again to see if that fixes it.

mobo is asrock ab350 fatal1ty

Try another ssd it could be bad.

SSD could be bad even if i was able to install windows on the ssd?

Are you mining when it shuts off? Does it shut off if left idle?
What does it take to bring it back to life? Reboot? Power cycle?

Are the risers powered or do they draw power from the PCIe slot?

It seems like power is being shut off to the card but if it's powered
correctly I see no reason why.

Since you tried all the other PCIe slots (I presume all are x1 and require a riser)
try the GPU in the x16 slot using a riser instead of a direct connection. Since
it works when connected directly it will prove one way or another if it's a riser
problem.

Something else you can do is try to artificially reproduce the same symptoms.
With the card up and running disconnect the power cable from the riser.
Do it again but disconnect the data cable.

no i wasnt mining when it shuts off - idle or not it still shut off. the risers are powerby 6 pin cable to PSU.

anway i did a fresh OS install and knock on wood, it seems to be working now - i have had the risered gpu detected and powered for over an hour now.

what i did different this time : disabled win10 updates after install and did not install any mobo software.also i let windows install all device drivers. so my guess is either win10 updates or the mobo AMD all-in-1 drivers caused the issue.

i did install the latest nvidia 436.30 driver. at first it didnt appear like the risered gpu was being detected, after reboot and reinstall again it finally detected. i guess windows was doing something in the background and finally detected it.
