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

[Mattthev]

Hey Matthev,

Good guide and I've been scrambling around trying to get my speeds over 25MH ETH + 730MH sia per card(dual mining with Claymore V10) but have struggled.

Currently running rig of 6X RX480 Sapphire Nitro+ Elpida. New blockchain driver and and using Anoraks Memshift Bios. When I tried using the Overclock Bios it would trip out my 1200w rig after it started dual mining but it achieved around 27MH.

Also is it important to DDU and reinstall blockchain driver every time? Can't I just run Pixel patcher?

Anorak's bios won't perform very well. You need better timings, you may try those here or I have better one. For Elpida Eliovp should have best timing from what guys telling here.
It's better to use DDU, but if you don't change voltages it should be fine not to do that.

Have you tested an 8-GPU rig?

If so, is the hash rate per card (say 30.1) the same when all 8 GPUs are plugged in?

I've only saw problem with different hashrate on old Intel 900 series mobo. Or you mean like the difference between cards? It's pretty normal, every card is unique and for Hynix it applies two times.

I have eight Gaming X 580 elpidas (4gb). Initially setting the cards up, I put them in pairs then tried the highest hash rate they could get. They easily give 30.1 up to 30.4 with <30 mem errors running +12 hrs. I did these 4 times and out of 8 cards, only one cannot do >30Mh.

But when I put all 8 cards they only manage 29.5 up 29.9 with a total hash around 234ish.

Mobo and CPU? CPU utilization?

G3900
Biostar BTC Pro
CPU utilization is around 20-30% while mining so I'm dead sure it's not the pain point.

Messaged him but he's probably very busy to be interrupted by my query regarding 1 rig Seem to have been able with AB to overclock to 28MH but haven't been able to fully check the accuracy of it. Will also check increase in power draw etc over the weekend.

hi guys
i am totally newbie
i have 11256-35-10G card. sapphire 4gb elpida mining edition
this is my gpu-z screen
and i also attach the original bios rom
it is completely diffrent in timing section
my current hash with blockchain driver is 22Mh/s
can anybody edit the rom?
and expain why timing is not similar to usual

thank you all


ps. why i can not attach my rom to the forum
link to download my original rom:  https://uploadfiles.io/4spcn

Great, I've ordered 3 vega 56.

You need to use other version of PBE, try PBE 1.6 or SRB Polaris. Links are in the first post.

your Polaris Bios Editor 1.6.2 link, stinks.

I have two identical cards, Asus Strix rx580 oc 8gb Samsung memory modded bios with Ubermix 3.1 straps on 2000 and 1750. One is working perfectly fine on stock speeds. Other one getting some memory errors, and after about 1h, hashrate on it slowly begins to drop. When i downclock memory from 2000 to 1950, it works fine, without memory errors, but hashrate is 1 mhs lower compared to the other one without problems. I did try to copy 1750 to 2000 strap, Ubermix less extreme 2.3, same thing happens.

Is there any other way to do something about it? Their memory quality is just different or i'm missing something?

Didn't touched anything about power and voltage so far.

Yep, silicon lottery, you might try Uber-mix 3.2.

I know that  You can always google it.

Can someone please mod my MSI RX 580 8GB HYNIX? - im worried about modifying and killing my gpu

[Tropic]

Hey, I've got gigabyte rx570 4gb gaming card.
I did change the timings with Polaris Bios Editor 1.6.2(it did strap 1750+). When I did strap it myself from 1500+ or 1750+,it only increased to 23 mh/s. Also I am using the blockchain drivers released at 23rd of August.
My hashrate(25 mh/s) doesn't change when I o.c from 1100/1850@150W to 1200/1975@170W. Although amount of shares accepted increases slightly.
This is my bios:https://www.mediafire.com/file/9b2d654xim5d8re/gigabyte_570gd_samsung_25.rom
Can anyone help me? Thanks in advance.

Edit: Somehow I managed to get 27 mh/s@130w with the same rom

Looking to try any new straps for Sapphire Nitro+ RX 580 (11265-01-20G) with HYNIX memory.

Using PE 1.6.1 Good Hynix Mining strap at 2000 and 2250 only gets 765 (stable, no mem errors ever) at 1250/2250 for XMR.

[treanski]

to high core clock, to high memclock and probably crap miner settings...hynix can go easy over 900 with 1130/2050mhz

[arjet]

dear all, i have power color 470 4gb mining edition with elpida memory, i mod bios same like what i did to my 470 4gb gaming edition. but why this mining edition draw more watt when i check in GPUZ? mining edition brown box draw 85watt, and gaming only 65 watt. is there any how i can mod my mining edition so at least 65 watt in gpuz? i mod only strap 1500 up. that is.

thanks, hope somebody might help my. regards

[dragon002]

You don't need to mod the bios for that. Your base voltage is probably just higher on the mining card. Lower it using Afterburner or Overdriventool or Wattman... Or whatever you feel like using.

Well, no thanks to anyone here, but I've managed to mod the ROM and get 833 (stable) at 1210/2180 for XMR with Claymore 10.2.

What Hynix type do you have?

If you only want lower power consumption you can just undervolt the core.
