So it must have something to do with AMD Cards....
I agree, it must have something to do with AMD cards.
I experienced the same thing before on one of my VEGA rigs. I ran 13-GPUs on a G4560 Petium processor with 4GB RAM. GPUs were 4 VEGAs and 7 RX470s. Opening radeon settings took forever too. I reinstalled everything and used blockchain drivers instead, works perfectly even up until today.
Did you ever find out what was the actual issue?
I've reinstalled Windows 2 times now, doesn't seem to make a difference.
Also, just curious did you re-install with all GPUs connected or connect 1 at a time afterwards?
Hi, I am still on it since it occured 2 days ago for me. I need a solution.
So far, reinstalling Windows or drivers did not make a change. Also I will post mor details in my thread, since it has a more open topic. I opened it to get more attention since the problem is not only related to the B250 Mining Expert. I had the same behaviour on a Gigabyte and on a MSI board.
Thanks for mentioning that. Perhaps its a common issue.
Have you tried opening Task Manager to see if anything is eating up the CPU when lag occurs?
For me it seams to be "Windows audio endpoint builder", but not always.. but killing it or stop/disabling the service does not seem to solve it..
