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.
