Re: AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly
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!

I have Vega 56 with 64 BIOS, 6xSapphire REF cards with samsung RAM. If I put Mem over 960 teamred is freeze and restart. SocMhz jump from 960 to 1107, but I can't set in HiveOs. I think SocMhz will be max 1028.
Core 970, 840mv
Mem 960, 800mv
I get 45Mhs ~100W
using these timings:
--CL 20 --RAS 20 --RCDRD 11 --RCDWR 12 --RC 43 --RP 14 --RRDS 3 --RRDL 6 --RTP 5 --FAW 12 --CWL 8 --WTRS 4 --WTRL 9 --WR 14 --RE
F 65535 --RFC 248
If I put RC value under 42, ETH MHS growing up, but imediatly crashed.
Any better timings to these REF cards?!
Vega 56 is the bios to run. 64 only uses more power but doesnt provide additional hashing. Most will flash their 64s down to 56.
I tryed, and 45MHS without any memtweak, but if I set some memtweak modifications then teamread is immediatly crash/reboot.
