In short, try the following for a 50-51 MH/s setup:

1) Set clocks to core clk 1075 MHz, mem clk 1107 MHz, voltage at 850
mV. Your card may need to clock down the mem clk to 1050-1080 MHz
to be stable with no hw errs.

2) Use the following modded timings:

--CL 20 --RAS 30 --RCDRD 14 --RCDWR 12 --RC 44 --RP 14 --RRDS 3
--RRDL 6 --RTP 5 --FAW 12 --CWL 8 --WTRS 4 --WTRL 9 --WR 14
--REF 17000 --RFC 249

3) Hopefully it runs stable and you should observe a hashrate around
50.5-50.9 MH/s. If your GPU can't handle the timings, you need to
relax them to less aggressive variants available in the AMD mem
tweak thread on Bitcointalk, or come join the TRM discord for
further suggestions.

4) For better efficiency (but lower hashrate), tune down your core clk
and try to further lower voltage while remaining stable.

5) We reiterate: _blast_ your fans and monitor your HBM temperature.

thanks man your setting helped me to get it at least stable at 50.8 mh/s after 3 days of trying Cheesy

but still I'm on around 1100w per 5x vega64 system I think it can get lower
