Well I wouldn’t say ‘indeed’. You think 50% more on the wall makes sense? Obviously not, and that’s why I’m saying that when HiveOs says you’re Vega consumes 110W is just Fake. The real consumption for the 12v rail is aroung 165W.
With gigabyte Hiveos says the truth.

Hi,
Any guide on how to set VDD on arch linux? is this the same as core voltage? I am using rocm-smi to undervolt and overclock.
Max I’ve gotten is 40Mh/s, reference vega 56. I dont know what I am doing wrong. Tried everything. Using teamredminer.
Do I need the amdgpu-pro drivers? Those have been removed from arch and only Ubuntu has them now.
thanks for all these informations, i will test it today
but hynix smaller as RCDRD 17 for me normally crashed.
and for my BIOS problem of the VEga 64 AMD/ATI, do you have an idea ?
i have test 5 or 6 different BIOS but nothing , the card don’t restart with an other bios as stock
the 56 hynix and the 56 samsung are normally from MSI model, i have flash the bios with the bios Saphire
Anyone use MSI vega56 air boost(Ram Hynix)?
I can’t reach more than 44MH/s
Any timming suggestion for me?
core 1028 mem 830 on this timming when push mem to 840 alway gpu dead lower than 10 min
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
When used 3 timming below this ram can go only 800-830 can get hast maximum only 43.85MH/s

yeah, i shaved 10mV vrom all vegas and 15 from all my 12x 5xx cards, total consumption dropped a bit, and what was suprising to me is that many gpu´s hash went up a touch with lover vdd.
I think im gonna let rigs just roll on, looks like eth is down and rewards are up for now so - 
I´ll look from the side for a while if u guys come up with some new trick´s with straps

Nice, must be as low u can go! no way i managed to go that low…is that MVDD 1265 that makes that possible?? My hynix died at 815…vega´s! 
, too many factors effecting each others 
good hash, can u please share your straps for reference. i have same card with different vbios, so im gonna give it a try with your vbios…this vbios must be why i havent been able to sqeeze more from that red devil…
If it’s true I shouldn’t have sold my Gigabyte Hynix running stable 52mh

Try these settings of my best MSI Vega64 liquid

Hi. Im going crazy with my vega 56. Ive noticed you have One with the same memory than mine, 113-376XL-UO2.
Every strap ive tried makes the GPU dead after some minutes miming
Can you Share the BIOS and straps you are using for this?
Best regards

I tried several different straps and customized versions, your starps were too tight for this card…same card and same vbios,thats the way it is with gpu´s, u have a good one, mine is good allso but dosent tolerate high mem. Thats max mem and core. This is with different set of straps. im really happy that this samsung is on the same level with others now. Will see if it hold up in long term, i have had similar values on this one before witn 54.8mh, but those were not good for 24/365 ops and got too tight when ambient temp went up…all variables…
im really happy that this samsung is on the same level with others now. many thanks for sharing info 
Perhaps too low voltage? You have to share your settings to let us help.
I’ve got one of those, but can’t get it over 48MH/s for now either.
My mem is higher though, but rcdrd is still high as 19:
core 1080 vdd 840 mem 940 mvdd 1270

I like the MSI Airboost vbios, but not their actual GPU’s 
Thanks this very nice strap now i try on mem900 get 46.33 if stable more than a day i will increase.
once you found your max stable mem, you can try do decrease rcdrd step by step; this should keep you busy for the next few days
