If any of you have updated to HiveOS version 210401 or later, it now has the option to put absolute core clock on the OC page of the card. I’ve tried it out but with mixed results.:
Note that whenever you put a number higher than 500 on core clock, this will be interpreted as the absolute core clock frequency that you want for the card. On the image above, you can see that there GPU 3 and 4 no longer need a PL value. GPU 2 is using my older OC settings.
It’s my first time to try it out so there’s more you can check but I hope somebody discovers better setings that can result in lower watts or even a small bump in hashrate.
