using Vega 64 flashed to 56

with  --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

Core: 1028
VDD 840
MVDD 800
Mem 1028

i'm getting 47.340 MH/s 114w (on phoenix miner) 54C Mem:75C (average based on 4xGPU)

wonder if that's possible to get even better...

for people interested in the flash I used amdvbflash (the same one i used for rx 5700 xt flash) with the equivalent model to my vega 64 (Nitro+) on https://www.techpowerup.com/vgabios/?architecture=&manufacturer=&model=RX+Vega+56&interface=&memType=&memSize=&since=

Vega64 flashed with Vega56 bios

using theses timings
--CL 20 --RAS 26 --RCDRD 12 --RCDWR 12 --RC 38 --RP 12 --RRDS 3 --RRDL 5 --RTP 6 --FAW 12 --CWL 8 --WTRS 4 --WTRL 9 --WR 13 --REF 24000 --RFC 239

Core 1097Mhz / 825mV
Mem 1028Mhz

you can get 54.5Mh/s solid ethereum hashrate at 115w to 130w depending on your model!
