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

[jaykavathe]

Do you have Custom memory strap for new Micron memories in MSI cards? I heard these can push beyond 30-31 on RX470 Mining Edition but cant find the straps.

I can pay if it works.

You can try my strap from rx560 maybe, if its the same micron memory

Well looks like there are these new micron memories capable of pushing RX470s past 30. I am ready to pay if one can find the right strap for these new mem. I am getting 29.7 MH/s out of RX470 mining edition.

My bios is here

https://bitcointalk.org/index.php?topic=3052745.0

you can extract 2000MHz strap and try in your card...since it has twice as wide bus, you should be able to get more than 32MH/s
if you manage to run it at 2240MHz memory speed...that probably mostly depend on your 470 card cooling (and some luck)

I tried it and it didnt run at all I appreciate your help though. I am working with the OP here, seems very helpful and I bought the software. Seems no brainer if you are new to tuning and stuff.

What do you mean by "didn't run"?

Card stuck at "0" MH/s after restart which other cards were showing hashrate.

I don't have any Micron, but I've got info from testers that it works only with some cards seems so. Good job anyway!

No worries, you have helping a lot giving me multiple options.
Great job man, I will spread the word with my bulk GPU buyers. I am also tied up with few rig builders and will recommend them. Already shared license with one of them. I can be your tester too and can help.

Card stuck at "0" MH/s after restart which other cards were showing hashrate.

At what frequency? Mine work up to 2240, but with very good memory cooling, most other cards fall into
2050-2150 range

Ahh, that could be one reason. Let me try one more time then.
I was going at 2275. Let me retry with say 2200

Edit - Same issue. Card shows 0 MH/s even at 2200 and 2100.

Amazing Guide ! Thank You for share.

I Need DGB Coin Guide . How to mine with amd gpu  ?

Thank You.

Digibyte is a multi-algorithm coin so you can select which miner and associated algorithm you prefer to use.
I have mined DGB in the past and liked to use the Skein algorithm.

To mine with Skein I've used CGminer and SGminer-GM-5.5.5:

Here's what I understand how to do it:

plug in individual card
install drivers
Back up BIOS with ATI flash  <---- call it last 3 serial with "backup"
open BIOS with PBE
One click timing patch
Save As   <----- call it last 3 serial with "modified"
Flash BIOS with ATI flash
uninstall with DDU
reboot
install drivers
install pixel clock patch
reboot
set to compute
reboot

Can the compute setting be done before the 2nd last reboot?   saving some time

If I'm doing multiple cards can I return to beginning after uninstall with DDU?

[big al]

Figured it out, compute setting only requires a reboot of the AMD software.   Duh.

I've got two MSI rx580 v1s running.  Unfortunately only single fan.   One is 1130/2200 and the other is 1130/2150.  Haven't played with voltage much but I am lower than stock around 930 cpu and ram.  It's very nice to be able to set the voltages, speeds and fan profile right in the BIOS.  I used the one click timing, then used the other software to fine tune things.

Getting a little over 31 each on claymore.

I find some of the naming on the utilities and the AMD software to be a bit weird.  They tend not to match each other.  So if you want to "program" a card to do something, you have to check to make sure it is doing what you want.

I am not reinstalling drivers. I flash one card at a time. At the end I connect all 13. After 13 is connected I run pixel clock patch.

Not sure what I'm doing wrong.  Can't get undervolts to work, lowest I can get is .925.  BIOS, wattman, MSI, and TRIxx.  One card I believe is toast sometimes I get 8 mhs.   The second cards hashrate has dropped to 22 or so set at 1100/2150. 

Tried the blockchain specific drivers that didn't seem to help so I switched back.  I havent seen a single GPU memory error in HW. 

[big al]

Got the volts thing solved.   Static volts is better in the BIOS and for some reason my GPU and GPU RAM volts are locked together.   So you can drop the core volts all you want if you don't also drop the ram volts nothing happens.

Another odd thing is if I flash say 900 mv for the ram it will always be 950 when I start.  Nothing I can do.  Since they're locked together the core will also be 950.  I'm guessing wattman changes it.  What I did was reduce the volts to minimum on all the core fields then just keep lowering the ram field 5 mv at a time.

Both cards are undervolted to  .806 for both the core and ram.  Zero memory errors and no mining problems.

One is 1050/2200 and 28.3/850   66c at 3100 rpm  110 watts
Other is 1100/2100 and 28.3/850   59c at 2600 rpm   108 watts

Is there any way to split the volts?  I could probably up the ram on the one card if that could be done. 

These are MSI rx 580 v1 reference cards with a single fan and Micron ram.   The store where I bought it has more.  But I'm not sure if they're the best?

I am in doubt which of these RX 580 GPUs should i buy that gives the most hashrate for ETH and or ETH dual mining with decred, or it doesent matter which RX 580 GPU i will take they all have very similar hashrate (30-32) with Pro Performance Settings ?? MSI Radeon RX 580 Armor 8G OC , ASUS Dual Radeon RX 580 OC , POWERCOLOR Radeon RX 580 Red Dragon V2 , XFX Radeon RX 580 GTS Black Edition , XFX Radeon RX 580 GTS XXX Edition , GIGABYTE Aorus Radeon RX 580 8G , ASUS ROG Strix Radeon RX 580 TOP , ASUS ROG Strix Radeon RX 580 OC , all gpus are 8GB memory.

It depends on memory type if you can get Samsung memory type you are lucky it can give you a better hashrate and stable with low temp base on what I experienced any brand can have Samsung memory.

Don't try the powercolor brand I had old experienced with that brand it gives me higher temp than the other cards. Try Asus or MSI mostly Samsung memory is in this 2 brand.

It appears I'm not really gaining anything with the timing straps.  Micron ram.

You're doing something wrong, then

[Mattthev]

You also need OC the memory, do you have compute workload?

[big al]

Yes compute on all 3.  Here's my data:

Card #1 NO BIOS mod just clocks and voltages in wattman

1100/2145   
28.1 mhs

Card #2 BIOS mod  (yours)

1100/2000 <--- unable to overclock ram much without errors, maybe not enough volts?
27.5 mhs

Card #3 BIOS mod

1100/2150
29 mhs

Is this typical?  Maybe card #1 will go over 30 with a BIOS mod?   The cards are MSI V1.  The 3 are within 7 numbers of the serial (663,668,670) with the same Micron ram.

Is there a way to split the voltages? I always check to make sure the BIOS is properly applied.

Probably timings problem. If you bought bios from my store, contact me via e-mail.
I've never had problem with same voltages for Vcore and Vram. You should use Overdriventool instead of Wattman.

I will play with voltages a bit more and a few other things, get more data then email you.  I just don't want to waste your time until I've covered all my bases.

Should I uninstall Wattman?  How would I do that?  It is an annoying program.

[big al]

email is sent!

For the one card yes it did respond to more volts.  But none of the 3 cards respond to any memory speeds above 2000. 

The non flashed card is running 27.7 currently, the two flashed cards 28.9 and 29.0.

Am I wrong to assume there is more to tweak here or is this expected?

[big al]

Happy to report much success!

One card can go to 2250 and another 2270.  I find you take the GPU memory clock rate and divide by 1.81 that gives you the optimal GPU clock.  Clock rate less than optimal affects hash rate, clock rate above optimal causes you to increase voltage or risk stability.  Also I was using claymore 10.6 and 11.2 is faster for hashing but seems unstable if you're pushing the cards hard.

One card max is 32.9/986 but that's really pushing it hard at 1254/2270 and 143 watts.  I'm happy with both at 1215/2200 and 129 watts.    The better card does 32.1/965 there. The cards seem to behave the same regarding voltages but their output/efficiency is different and max GPU memory speed is different.   Silicon lottery.

edit: It makes sense economically to run it at max speed but these are single fan units and they're already screaming.  Does running at max clocks affect GPU life or is that strictly heat?  130 watts, 61c and 2800 rpm fan.

edit again:

32.2/966 card 1
30.6/920 card 2

Both are set at 1215/2200 and 880 mv.  125-130 watts
