Anyone had a problem with gpu that works on 50% core clock instead 100%,in this case instead working on 1600mhz it works on 800?faulty gpu or something else?
at first notion; it sounds like a damaged gpu; but even a driver can cause this type of problem.... might wanna open up a thread about it....
I had this issue before. I think in worst case its a damaged GPU.
Mine issue was either driver related. Basically had to use DDU and reinstall everything from scratch, even MSI Afterburner. This solved the issues.
Another time I had this was when I had a bad riser and it was annoying because it took me forever to diagnose it.
What you should do is put it in a regular x16 slot and run some Game benchmark using the latest AMD drivers with the stock bios and see if you can get it to work at the stock clock, if it fails this... then its a damaged GPU. However its most likely some driver issue or bad riser in my opinion.
