Hi,

I just need to verify something about the amd beta blockchain driver.
I have a rig 8 GPU RX580 Gaming 8 Go (Hynix), in june i got 242 MH/s.
Actually in august i obtain 233 MH/s, in order to solve this drop MH/s, i installed this beta blockchain driver i got 248 MH/s, but i met issue with GPU clock speed frequency alternatively jumping 1000 to 1300 MHz.
Is somebody here met the same issue and find solution to solve this?

Thank you for help.

Had the same problem with my RX570, also befor kernel update. I flashed only 1 clk level to the RX570, after that they run fine.
With the RX4X0 i had no Problems to set the clk with rocm-smi, they run stabel

I have no issue with official driver, i only meet this issue gpu clock frequency jumping alternatively non stop from 1000 to 1300 MHz with the beta blockchain driver.
I dont see what you mean, you flashed only 1 clk level to solve this issue?

Can you undervolt with the blockchain driver?

Yes, but only with Afterburner version beta 4.4.0.16, i found it on the link below, i tried to undervolt it was ok for consumption, but jumping issue always there.

I can report that undervolting via Trixx is working, without the jumping issue.
