Ethash is even better than cn-trtl wrt being able to drop core clock on vega.  Where you may lose 5+% h/r on trtl by going to cclock p0 (852mhz), I saw zero h/r loss on ethash when doing the same, at least w/ stock timings.  Should allow you to get your voltage down significantly - closer to 800mv.
why do you need such low gpu clocks if vega is perfectly capable of higher clocks with <800mv voltage?

it is vega56 pulse with hynix 20.5kh/s turtle btw
vega56 ref samsung can do the same ...

Wow, with Soft PP or AMD tweaking ?

Great info
19.4.1 drivers allow you to control and disable (grey) all p-states via ODNT! (except mem p2 voltage)
Just set mem P2 voltage to 800 with softpowerplay ))

And make working freq ~1200
Than test stability, than apply timings  -rc 37 --rcdrd 12 --rcdwr 5 --rp 13 --faw 16 --rtp 4 --rrds 3 --rrdl 3 --CWL 6 --WTRS 4 --WTRL 9 --REF 12800

Use --cn_config L22+22 or --cn_config L20+20 for teamred ))

And last but not least - screen of overnight testing no hw errors and h/r on the pool is ok

Greatttt, thanks for the Enlightment
