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.

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=

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

Forgot to mention that you will need to use TeamRedMiner to get the 54.5Mh/s

Have you got Samsung or Hynix memory?

I tryed, and 45MHS without any memtweak, but if I set some memtweak modifications (all my working 64bios sets) then teamread is immediatly crash/reboot.

Vega frontier edition water cooled.
just to confirm you can get this to mine on latest windows 10 on latest phoenix miner 5.4c.
the pro drivers are no use cos they lock core at 1600 and hbm at 945 using huge power .
you have zero control with pro drivers and hash arty stuck at 36 mhash.

so do amdcleanup in safe mode then install driver 19.7.1
then you add registry dword KMD_IsGamingDriver
set it's value to 1
reboot
you put it with all the other dword that start with KMD - so search for KMD
we found them in a different subfolder from the one mentioned in other guides

once you reboot the driver will be red (rather than pro blue) and you can control everything with the phoenix config.txt
just like every other rx card.
we went up to 41 mhash and dropped a MASSIVE 100watts at the wall !
our approx config was
core 1040
mem 1060   (this determines hashrate so its up 12% from stock )
core volts 900mv
mem volts 1000 mv
fan
-tt -60  (fixed fan at 60%)
did not wanna push the mem any higher and with this config everything seems fine and dandy
will reduce volts if its stable .

why would you get a vega fe and mine with it?
thats a whole other question.
but it looks amazing its the "golden" child of gpu minings.
rx5600xt draws about half the power of vega fe for same hashrate approx

[dastardlyman12]

RX5600XT top tip.
the bios that famous mining youtubers have made available for rx5600xt
just wont install on rx5600xt using the recommended amdflash 3.04 (ssid mismatch)
you can force it on using amdflash 2.93 even though this is not meant to work - it does.
treat 5600 as 5700 for forcing bios on.
after doing this i got 43 megahash but my vram was getting hot.
i adjusted the fan turn on and off points downward using morepower tool
and flashed that on. all good now. ho ho ho happy xmas

Hey,

i am new to AMD Mining and I got a used ASRock Vega 56.
Right out of the box i get around 35 MH/s.

To improve the rate, I tried some timing settings in this thread for other Vega 56's, but the GPU crashes instantly.

Can someone help me ? What settings should I use, and can I improve my rate by doing sth else?


Mining with RedMiner, see Screenshot below for Scrrenshot of rates and MMIO

Your Core and Memory Control are way out of desired values. Try P7 1150/850 and P3 940/825 first, than try to play with timings.

EDIT: Huh, also decrease temp limits or upper fan curve keeping memory temp in 60-65 degrees range.

Wow, the P7 and P3 settings pushed it to 42 MH/s! Thanks a lot!

I have no idea what to try in timings, as i dont understand the technical background. Any suggestions?

Sounds great, but i dont know which timers i should set. What are yours?

This card is very old Rev 1....i cant keep stable above 1090 /1020...and if i lower volts it hangs.  So its ok with the miles its seen.

Depends on card type and memory manufacturer how far can You go changing timings. You will easy reach 50 MH/s googling about your type of Vega and ETH memory timings.
