I sold that card. Try amdmemtweak for Samsung and then change RCDRD to 20. Then go down as close to 12 as your card will allow without throwing to many invalids. Keep VDD at 850 till card is stable then you can lower it to get the best wattage setting. Hope this helps. Alan
As soon as I go down the memory clock will turn off immediately.
Vega 56 ASUS
Samsung memory
And what’s even more interesting is that I see this on a monitor. however, these parameters are not specified
Here’s an example of one of my Vega56 config sheet. I think having the MemMhz at 1125 is what is tripping you up. It’s probably too high and the GPU is just crashing because of it.
amdmemtweak --CL 20 --RC 36 --RP 14 --WR 14 --CWL 8 --FAW 12 --RAS 22 --REF 65000 --RFC 249 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 14 --RCDWR 12
My GPU 0 is ASUS the question is Samsung or Hynix memory? Can you post a pic of your OC screen? Try this. Similar to WERT420

Samsung mem
amdmemtweak --CL 20 --RC 36 --RP 14 --WR 14 --CWL 8 --FAW 12 --RAS 22 --REF 65000 --RFC 249 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 14 --RCDWR 12
it works very nicely thanks to these settings!
amdmemtweak --CL 20 --RC 36 --RP 14 --WR 14 --CWL 8 --FAW 12 --RAS 22 --REF 65000 --RFC 249 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 14 --RCDWR 12
Bump the core to 1100 and you’ll hit 55 mh also set your fans to 70. No auto fan.
On your RX 580’s if you do the one click Polaris memory tweak and flash it to your bios you should get 31-32 M/h…Or just try adding the memory tweak in Hiveos for those cards first.

thanks for the help! everything works well at last.

Hi I could not reproduce your results.
I tried it on my ASUS card.
I filled in the MVDD box but it does not show in the OC.
Not sure why.
What version Hiveos are you running?
my tweaks :
amdmemtweak --CL 21 --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 17 --RCDWR 12
Hiveos :0.6-213@220110
TRM 9.0 ; --eth_config=B448
all my vegas are 64 flashed 56 , im not sure if a vega 56 can handle high memory since the vegas 64 are hardware-ly better
Hello everyone, I have installed this vega 56 MSI but I can not bring it up and have no errors, I managed to bring it to 52mh / s but then it goes into continuous restart … can someone help me?
amdmemtweak –CL 20 –RC 36 –RP 13 –WR 11 –CWL 7 –FAW 12 –RAS 23 –REF 65000 –RFC 148 –RTP 6 –RRDL 4 –RRDS 3 –WTRL 4 –WTRS 4 –RCDRD 14 –RCDWR 4

Hello again,
Yesterday i’ve received an odd advice from a long time miner person (and friend).
He was very unconfortable with the memory clock settings of my Vega 56 at 1025mhz. He showed me the Vega’s specs at Techpowerup, as follows:
According his point of view, a “safe” overclock for this memory is 25% over the base clock, which is: 786mhz + 15% = 904mhz. But as you can see in this topic, we all use these settings around 1020,1025 and more!
I said that my card was running well for months (precisely, 4 months!) and he said that it won’t give a longlife for the GPU.
So, I want to hear your opinion and leave a question: how long each of you are running with this settings?
Thanks.
for Hynix 52.50mh 110w stable but can go to 55 with some hw. just put step by step 5mhz on both memory ans core don’t touch SoC.
your core is a bit low and the tweaker is for samsung memory. try my settings 
wait, this one is to restore stock bios right?
Sorry, is any blower model in there?
Is there any focus on getting these cards as efficient at the wall as possible now that electricity prices are shooting up (at least here in the UK)? I have been running my msi airboost vega 56 at 55mh/s for 124w software on hive for a few months now, but having recently taken it off the AMD rig it’s on in order to troubleshoot a pesky temp 511 error (that has reared it’s head since updating the hive kernel). I subsequently found out that it was taking up to nearly 180w at the wall (difference between card on rig and card off rig @ wall). That’s 56 watts higher than software reporting and a 0.300 efficiency level which is pretty poor compared to RDNA, RDNA2 and nvidia turing/ampere etc.
Has anyone experimented running these cards at sub 50mh/s for sub 100w software power consumption? I know that my MSI airboost is a bit of a power hog compared to some other models as I’ve seen 100-105w software on the best vegas (e.g sapphire) but I expect these would still be doing circa 160w at the wall. Genuinely thinking of retiring my Vega given the issues I’ve had and it’s poor efficiency levels
I’ve installed my new Vega 56, hynix memory, and i see 115w from software.
I shocked when i saw the power meter at the wall saying 195w (22w from the motherboard) 
Yeah the software reading ist far off!
Mine was at 57mh@130w butt it was close to 200w from the wall! That’s why I sold that card.
