Hi all, hope everyone is well.

I have a situation with one of my RX480's on GPU0 all of a sudden giving me only 2 mh/s on the latest Claymore miner, as well as during a test using PhoenixMiner.  

A few hours ago I was getting 31 mh/s for quite some time with absolutely no issues at all.

Since I've discovered this problem, I've made sure it was in compute mode (it was), I've properly removed and updated drivers.  

I've even reverted my card back to it's stock bios.   None of this has given me my precious 31 mh/s back, sadly.


Strange thing is, if I disable compute mode, while enabling graphics mode, I get a max of 12 mh/s on that card.   Compute mode only gives me 2 mh/s, no matter what stock/bios modded, tweaks I do.



What do you folks think is the problem here?    If anyone has any ideas, I'd love to hear them.

Perhaps the riser is crapping out on me?


Cheers.
