I have two R9 290's that are watercooled and I am having trouble keeping the ULPS mode enabled. It seems to turn on and off randomly between restarts. I have disabled ULPS in both msi afterburner and regedit. I also tried in Trixx too and setting each card individually. I am using the latest driver from AMD 17.4.1. There seems to be a bug because my second gpu either stays at 300 MHz (150 MHz memory) or has zero activity. Then randomly I will restart and it will be working for a bit and then cut out. I believe my overclock is stable too.
I can run a benchmark and get one number then run it right after and get a completely different number.
Anyone have a consistent way to keep ULPS active?
