Wondering if someone has an easy solution to this new problem.

I've been mining for 1 year with no problems across my 5 rigs.

All of a sudden, the majority of my rigs (using various versions of Claymore) are showing GPU0 as 0.00 MH/s. I can only seem to mine if i plug gpu0 into my monitor, but then my other rigs will stop mining.

When I relaunch claymore, it hangs at POOL/SOLO. Eventually it will get going, but GPU0 will be at 0.00, then it loops.

I'm using various versions of claymore across my 5 rigs. Aug23 blockchain drivers and afterburner.

Please help. My hashpower is useless right now.

If you're using Windows operating system this may be the solution.
Windows doesn't like to operate well without a monitor attached to the primary video card.
But attaching a monitor isn't recommended when mining.
Try buying a Dummy Plug and put it on GPU 0.
They make HDMI dummy plugs in several forms.
That works great for me. Something like this one at Amazon.
I don't know why this would suddenly start, but I think it's worth a try for you.

Thanks for your advice. I'll give it a shot.

I am indeed using Windows. Even though I've done all I can to prevent automatic updates, even with regedits, Windows seems to update my machines. Often I have to DDU and reinstall the blockchain drivers, which is quite the pain. I assume these new issues I've been dealing with are likely related.

Your advice seems like it just may work. I do know that when I login to my rigs via team viewer, the aspect ratio is perfect if I login to a rig that has a cable plugged into a monitor, even though it's off. Otherwise it's 640x480 if there are no cables attached to GPU0.

Thanks again.

Have you done this to try to stop Windows Update ?
Maybe you already did that, but it has worked for me.

run services.msc
Scroll down to Windows Update.
If its shows running, right click and select STOP.
Then right click again and select Properties.
Set Startup Type to Disabled.
Exit the Services Menu.
Reboot.
Then check again to be sure its really disabled.

Actually I have done that about 4 months ago. It's currently set to "manual", so I must have either not applied this tweak properly, or it somehow mysteriously switched. Thanks for the reminder - I have gone ahead and disabled it.

Additionally, thanks to you I tried using a 4-port HDMI switcher that I had laying around to see if it would give me the same result as those dummy plugs you spoke of - and it has indeed solved my problem Cheesy

Cheers!
