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

[Bitock]

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.

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?

No, I completely reworked the timings myself - not basing them on any that were in the VBIOS before. Then I applied those to both 2000 & 2250.

How can I reworke the timings? Where can I read about it?

Nope - this won't help you rework the timings; my owner & I released that part AGES ago. OhGodADecode.

You need the specification because you need to look at the format of the mode registers, and there is where you'll find what you wanted to know.

You're in the right chapter. Now - which one looks likely to be the format for the one you want?

Hey wolfie, can you throw out a 2000 strap for a samsung that easily clears 30 Mh?

I have a strap found in the GDDR5 timings thread but could only go 29.9 and that's the card with the highest quality. Others only do 29.5 or 29.6.

If you would be so kind

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?

When you say beta blockchain drivers do you mean amdgpu-pro 17.40? I'm trying to figure out which kernel/firmware combo you need to run on linux with the dag fix but I keep breaking my install lol :p

Anyone have modded 'edw4032babg' ? (570 4gb elpida)

It's hella common - I've done it several times, but I've not focused extremely hard on it cause it's not one I've got a lot of.

Most of cheap rx 570's come with elpida :-/

My not so cheap Gigabyte Aorus RX580 came with Elpida too...29.7MH/s

No, because you've not specified WHICH Samsung.

Really? You can't hit 30 with THAT? It's not only the most performant of the ones I've worked on, it's also the one most tolerant to whack settings... What clocks you at, and what timing set?

I have the clocks at 1160/20502100/900 and the strap i'm using at 2000 is:

Code:

777000000000000022CC1C00106A5D4DD0571016B90D060C0060070014051420FA8900A0030000001011333DC0303A17

I'm at 2030MHz, and even default straps, with no changes at all, won't go over 2050 without errors in hwinfo


After bad experience with Hynix version of Gigabyte RX560, it wouldn't surprise me if I'd remove cooler and find
6GHz instead 7GHz chips there...and your lucky 31+ MH/s maybe even have 8GHz chips, so don't judge

[ronnylov]

The guides are made for Windows. Can this be done in Linux?

I just bought an used XFX RX 460 2GB single fan and if I mod the bios (maybe using a windows machine) will it work in Linux? I see there is a mod of windows driver to bypass bios signature check but there is mo mod required for Linux? It also seems possible to flash it with a RX 560 bios to unlock shaders but maybe not Worth it? I am mining Intense (cryptonight) so mods for Monero should be useful to me.

Out of 9 500-series cards, 5 of mine have that. You could say I went for cheap ones, but I bought them all no earlier than late June, so none of them were that cheap

I am trying to get a stable hash rate form an rx 470 nitro+ mining edition with samsung memory.


I have 8 cards running with the same bios (1750 straps copied to 2000), but one is getting waay to many incorrect shares. The cards are running at 1900 mem and 1050 core I have tried different frequencies, but could not find a stable one for that one card.

Any tips on what to try next? Should I maybe try a different bios?


Thanks

[bardacuda]

Try the ubermix straps. 1900 seems awfully low for samsung.

You think I need luck to get 31MH/s+? With 8Gbps Samsung, I can clear 34MH/s.

We were talking about Elpida, though...I managed to get 16.3MH/s on RX560 with 7GHz micron, I guess thats close to your
34 on 8GHz Samsung  (relatively speaking, considering is half RX580 in everything)

[bardacuda]

Actually he and greatauror were talking about a specific samsung IC. Although he is no doubt also using a custom kernel whereas everyone else is posting their hashrate reported by claymore in win, so his increases don't necessarily all come from optimized timings.

Like I say I have a few Elpidas and none of mine will even do more than 2020. The lowest 2 only do 1960/1970.

My bad I guess, replied to wrong post a few posts ago

I do benchmarks using Claymore's linux miner for this very reason!

So should I try harder or be happy with 29.7 on elpida?
Card is pretty hot because its in ordinary PC, that probably steals
some hashing power

@Wolf0

Ahh good to know. That makes it easier to compare then.

I remembered I asked you earlier about how to set up Linux and you said any use any recent kernel and amdgpu drivers and not amdgpu-pro, but you need the OpenCL runtime. Is that is still true now that there is a DAG fix? Is 4.10 a recent enough kernel? How do you get the OpenCL runtime? I read a comment somewhere that you are supposed to install the amdgpu-pro drivers with the '--compute' flag. Is that correct?

I really wanna get Linux setup and running so I can move all my rigs over, but unless I can get it hashing on par with Windows it's not worth it. I managed to get it running with amdgpu drivers but I was getting pre-DAG-fix hash rates, and ended up breaking my install trying to mess with it. I think that had something to do with blacklisting the radeon driver though (the primary GPU in the system is an R9 270).

Also are there any publicly available tools to monitor voltage/clocks/temps/fanspeeds, etc? lmsensors doesn't find anything and conky and grkrellm don't seem to be able to see voltages.
