What does it mean to have the "hw" code triggered for a GPU? My Radeon VII GPU is having almost a 40% "hw" triggering even though the pool is still accepting its share. However, the poolside hashrate for the card is very low. I am using TRM 0.5.2 and running my GPU @1575cclk/975mclk/855mV.

Any ideas what is happening and how to fix this?

Yo Bro
try to play with your clocks and votag and see which one is best for your GPU.
HW means hardware error and it shows that your GPU is not doing well.
40% HW error means you are losing 40% of your hashrate. try to increse your voltage and see if it can fix or not, and be careful to not break your GPU increase bit by bit.

Hi!

+1 for bumping voltage. My experience is that the VIIs react with hw errs when they're starved on voltage, V64/56 and Polaris cards typically crash outright instead. I can't run my VII at 855mV at your clocks, it would produce bad hashes just like for you. I do know other VII owners that are just fine at the same levels though, so silicon lottery/ymmv/etc. Try raising it +5-10mV at the time and observe the error rate. Also, make sure your fan curve is set to provide adequate cooling.

Actually, with my Polaris cards, if the voltage is just a tad lower than needed, it will throw HWs. A 1-2 step increase is enough to fix it.
