[GUIDE][TUTORIAL][XMR,ETH]How To Mod Bios RX470/570/480/580 VEGA Mining 💰⛏

Whats the best way to undervolt my cards?

I have 2 x MSI ARMOR 4GB RX570 and 4 x Aorus 4GB RX570 split across 2 PSU. From the wall i'm pulling 1010kw so very keen to drop this as low as possible. Getting 161mh/s from this rig and at  up 24Kw a day @ .30c per KW for power it's expensive, even with solar.

If you use Claymore miner, it's easy to set -mvddc and -cvddc.

I have 6-card rig as well and pull ~1040w at the wall, but these are 580s dual-mining 177eth 4.2Gh dcr.

I thought 570s are supposed to pull only around 90w eth-only mining?

Thanks you. I have just removed AB and add some commands into claymore config.
Now, my rig is working good, but memory error is still there (a bit).

good tutorial!

Welcome!

Try stepping down a notch on your memory clock, say from 2100 go down to 2075 until it's showing less than 10 errors per minute. The target however is to have zero for maximum rig stability.

What mvddc and cvddc are you using?

Thank for your reply.
Today, I have reduced CC: 1150, MC: 2000, mvddc: 930, cvddc:920, PL: 25. But memory errors have still appeared with minimum (2 errors/ minute).
I will continue.....

I'd be okay with 2 errors per minute, as memory errors doesn't necessarily mean a bad thing. Some mem errors means the card is correcting some stuff.

What you should watch out are thousand errors per minute. Voltage plays a lot of factor too.

is there any differences between the various brands of vega 56/64 in terms of quality?

Hello,

Thanks so much man for this Tutorial !!!!!!!!!


My rig base on AMD NITRO+ RX 580 8G Hynix + Ubuntu 16.04 Server with AMD beta blockchain drivers + Claymore:

Each GPU for "Estash"
30.7 Mh/s
Temp=62C
Fan=36%
120W ( 0.017$ KWh so I don't really work on that ^^)

On Windows the Hash is better 31.4Mh/s but Linux is more stable and...I don't want to work on Windows anyway.


Strange thing is when I start Dual-Mining my hashrate increase to 30.9 Mh/s and 970 for DRE but I will not use Dual mining !! Dual Mining is taking 60W more / Lot more noisy and Fan start to go high...

Someone have the same increasing Hashrate when dual mining?

[Branko]

Someone have the same increasing Hashrate when dual mining?

Only the people that don't know that dcri parameter works in single mining mode too

[clems]

That's a good point and thanks  

 

You could say: RTFM

ETH - Total Speed: ETH: GPU0 30.929 Mh/s

Thanks.

Hi, I made the mod, but the power consumption increased. Could you help ?

Doesn't matter for me ^^ but it can be good to know.

I have msi rx580 8gb with hynix memory. I took timings from here http://indeedminers.czechian.net/timings.html and wrote its to 2:1750, 2:2000, 2:2250. First I tried the first timing, after second. When I run miner my system crashed. What am I doing wrong?

I’m sure his Asic quality is higher than your cards hence the crash.

I suggest doing your own trial-and-error until you find your card’s sweet spot.

[phuocduong]

helpful for miner, i used his 470 4g (hynix), after mod mining ETH about 27 Mhz (claymore)

How can I get about 30mh/s from my card? I get ~27,7mh/s from original bios and writed timings from 2:1750 to 2:2000, 2:2250 without memory errors.
I read a lot of forums and find topics where suggest mod_bios for my card but only with a lot of memory errors.
Help, please!

I cleared 31MH/s stable, and 32MH/s was unstable at the time... but since I only have like one or two cards with that memory, I said fuck it; it's not worth my time to improve it to 32MH/s+, as it can be a *really* picky bitch.

Cool.
Are you write strap 2:2000, 2:2250 or other yet?
Timings take from 2:1750?

I did 2000 & 2250 - and fuck no I didn't use the shitty timings from the 1750 range, lol.

If I understand you right you write timings from 2:2000 to 2:2250, strap 1:2000 and 1:2250 you left unchanged?
