Vega 56 and Vega 64 guide

The fact is that ergo needs more juice on the core while eth needs only high memory clock. So you can go down with core which gives you less power consumption. This concerns all non-LHR cards (all AMD plus non-LHR Nvidia cards).
On LHR cards miners must cheat chip and pretend that it is not mining eth. That’s why power usage fluctuates and real power usage is higher than on ergo where miners can just mine with full power.

I made it back to vdd 810

My consumption went from 209w to 225w

Hello,
i dont know what i keep doing wrong. My two Vega 56 still getting invalid shares. I tried a lot different OC and straps. Maybe someone of you have an idea. I’m using Phoenixminer.

hello everyone, i’m new here.

I have a problem with vega 64 and vega 56, I used some settings that I found here on the forum and I got 54 mhs but a valid share appeared and some of the cards were interrupted, now I will tell you which cards are in order:

card “1: vega 56 with vega 64 bios” radeon "
card “2: vega 64 with vega 64 bios” radeon "
card “3: vega 64 with vega 64 bios” asus strix "
card “4: vega 64 with vega 64 bios” radeon "
card “5: vega 56 with vega 56 bios” radeon "

I’ll send you a picture below of my cards and settings in “amdmemtweak”

card 1: amdmemtweak --CL 20 --RC 36 --RP 13 --WR 13 --CWL 7 --FAW 12 --RAS 23 --REF 65535 --RFC 248 --RTP 6 --RRDL 5 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 20 --RCDWR 11

card 2: amdmemtweak --CL 22 --RC 44 --RP 14 --WR 16 --CWL 7 --FAW 20 --RAS 33 --REF 65535 --RFC 248 --RTP 6 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 16 --RCDWR 10

card 3: amdmemtweak --CL 22 --RC 44 --RP 14 --WR 16 --CWL 7 --FAW 20 --RAS 35 --REF 65535 --RFC 248 --RTP 6 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 16 --RCDWR 12

card 4: amdmemtweak --CL 22 --RC 44 --RP 14 --WR 16 --CWL 7 --FAW 20 --RAS 33 --REF 65535 --RFC 248 --RTP 6 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 16 --RCDWR 10

card 5: amdmemtweak --CL 22 --RC 44 --RP 14 --WR 16 --CWL 7 --FAW 20 --RAS 33 --REF 65535 --RFC 248 --RTP 6 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 16 --RCDWR 10

maybe my bios is not suitable for the settings I found on this forum and these are: :worried:

amdmemtweak --CL 20 --RC 36 --RP 13 --WR 13 --CWL 7 --FAW 12 --RAS 23 --REF 65535 --RFC 248 --RTP 6 --RRDL 5 --RRDS 3 - -WTRL 9 --WTRS 4 --RCDRD 20 --RCDWR 11

Mitrabrate, read the initial post and read the thread, you’re doing the opposite of what is recommended vega 64 → vega 56 bios not the other way around. Leave you vega 56 cards with original bios. All your ref cards can be flashed from hiveos with this bios:
016.001.001.000.008771

Also read this thread
Vega 64 - 54MH/s with less than 130w

ALL SAMSUNG REF CARDS CAN ACHIEVE 55+mhs ethash EZ TEBRAAAA

means cards that are vega 56 to leave them the original bios, and vegas that are 64 to put a bios of 56.

vega 64 used bios with 220w and vega 56 bios 160-180w can i put bios from vega 56 on vega 64?

if my reference is sapphire or gigabye do I have to ask for bios from that manufacturer?

also what settings should i use for amdmemtweak?

my first 1 card: sapphite 56,
2 card: 64 xfx
3 card: 64 asus ( asus not referal vega )
4 card: 64 sapphire
5 card 56: gigabyte

can i use this bios that you sent or do i have to find a specific model that i use

I put the same settings and everything as it says, vega 56 with vega 56 bios and I get 45.85mhs

try different straps:
amdmemtweak --CL 20 --RC 37 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 20 --REF 65535 --RFC 248 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 12 --RCDWR 12

also try coreclock:1050, memclock: 1020
Core Voltage, mV: 830 (maybe more maybe less needs testing, all my cards using 780-810)

For BIOS Im not really sure don’t wanna tell you something I’m not sure. AFAIK all reference models with Samsung memory use AMD Bios so it’s all the same, make sure you Subsystem ID is the same on your card as the new bios

Screenshot 2021-10-20 at 19.15.35

|Device Id:|1002 687F|

|Subsystem Id:|1002 0B36|

same number on your and on my bios…

i go testing your settings now …

i use this bios “Sapphire.RXVega56.8176.170811.rom” vega is 56 with 56 bios…
with this settings:
amdmemtweak --CL 20 --RC 37 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 20 --REF 65535 --RFC 248 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 12 --RCDWR 12

and get 49 mhs its first card.

should i change “gen3” my code is now “gen2”

gen 2 should be fine, what miner are you using seems to be problem here.
Use the latest teamreadminer 0.8.6.2, if you’re already on that one I really have no idea what’s going on with that card…
from “run command” run amd-info and check your clocks

remove any display cables if you have connected to the card

I have a problem, I constantly get disabled share, after I put the bios from 56 to 64 …

you mean invalid share ?
from what I known usually people flash to 56 bios for their vega 64 card.
And for your invalid share usually you need to :

  • lower you memory clock
  • increase your RCDRD from 12 to 14 or higher
  • increasing RC it’s also help from 36 to 37 or 38

Hi i put my vega 64 on vega 64 bios now with this settings:

amdmemtweak --CL 22 --RC 44 --RP 14 --WR 16 --CWL 7 --FAW 20 --RAS 33 --REF 65535 --RFC 248 --RTP 6 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 16 --RCDWR 10

And its stable without any invalid share 47,14 mhs

1100 / 850 / 1000 clocks…

can you tell me what settings in memorytweak raise mhs? what could be raised or lowered?

hello !!!
please can you help telling me how the hell you managed to make msi vega 56 hynix to 52 mhs ?
the best i did is 47mhs and i am suffering like a month .

if you vega memory card is samsung then you can use settings below :
amdmemtweak --CL 20 --RC 37 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 20 --REF 65535 --RFC 248 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 12 --RCDWR 12

if it’s hynix usually you can use below settings :
amdmemtweak --CL 20 --RC 37 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 20 --REF 65535 --RFC 248 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 18 --RCDWR 12

play with RC or RCDRD value, for hynix usually the value is much higher , you also can browse this thread from the top, many try to up their hynix memory performance but usually only achive average 47 MHS, 51-52 MHS if your are very lucky.

like I said , most people flash their vega 64 card using vega 56 bios (i also flash my vega 64 card to 56)
