0.16 final version is causing one of my AMD RX570 to drop Mh/s #1582

Closed jbramsden closed 6 years ago

jbramsden commented 6 years ago

I was previously using 0.16 beta 2 which worked really well and all my cards where stable. I've just upgraded to 0.16 final version and after about 5 mins I have one card that will continue to drop in Mh/s until it hits 0. I used to have this issue prior to 0.15

To run Etherminer I am using:
nohup taskset --cpu-list 1,2 ./ethminer-16-final --farm-recheck 200 -G -P stratum1+tcp://0xb6a169a1421a34af008bc8f0061629fc76c06f25@eth-eu2.nanopool.org:9999/mine1/jason@bramsden.com --cl-local-work 256 --cl-global-work 20480 --api-bind 127.0.0.1:3333 & >nohup.out

For the time being, I'm going to go back to using 0.16 beta 2.

Any ideas what can be causing this.

GPU1 is using a slightly different BIOS where I have clocked the memory to run higher.

Your printed log does not depict the issue.

I have one card that will continue to drop in Mh/s until it hits 0. I used to have this issue prior to 0.15

Which card ? The one with higher OC or the other ?

jbramsden commented 6 years ago

Sorry for not depicting the issue correctly. I will rerun the latest version to show the logs with it going down to 0. The card that this occurs on is GPU1 which is the one with the higher OC. AMD RC570 Strix Gaming OC. The other 2 are almost identical but have are not the OC version of the card.

jbramsden commented 6 years ago

I've been tracking this for running over 300 minutes and GPU1 is showing a gradual downward trend. I'm going to keep this running until GPU1 goes down to 0 Mh/s and I will update you. image

jbramsden commented 6 years ago

The GPU 1 is still going down, but very slowly. During minute 723 and 761 it jumped up in performance and dropped again. image

jbramsden commented 6 years ago

After 24 hours the card has not dropped to 0, so I was incorrect to raise this as an issue. As after 1424 minutes card GPU 1 is still around 28 Mh/s, I'm closing this as a none issue.

jbramsden commented 6 years ago

Just to add to this issue, after 29 hours of running ethminer 0.16 the Mh/s of card0 has jump up to 29.400 Mh/s.
