The ultimate way to mod your RX460-590 cards & newer (GUIDE) + consulting with all kinds of rig issues

[Hardcore Games]

Polaris is already as fast as it goes from the factory. If the card is not earnings its keep then replace it.

Shoot me with your RX 580 stock bios, or if it's modded I can try to get more juices off of it. Tell me current average hashrate and power consumption while mining. I'll fiddle around. I can't mod RX 5700 unfortunately.

Hi there,

I tried modding this BIOS for XFX RX 580 8 GB Black wolf 2048 SP edition. The BIOS editor is not recognizing my BIOS. Could you please help me do it.

I am getting 23-24 M/H only

Should be enough if your cards aren't pulling more than 150W per card. Your whole mobo/HDD/ram/CPU combo should pull max 150W so there's even some headroom. Of course, you may try daisy chaining another PSU and rule out the fact that your PSU is capable of running all those cards alone. Or trying bigger one if you happen to have one.

Not really. RX 580s pull more. At peaks, probably more than factory spec 185 watts. No matter what he does to his rig, if he doesn't upgrade that PSU, it's not going to end well.

I think the 580 8gb should run memory at 2000mhz instead of 1750mhz.

How can this be done? I am unable to perform any mod on the BIOS using Polaris editor. Can you please help me mod it?

It should have come from the factory with 2000mhz memory.

It should have come from the factory with 2000mhz memory.

The ram is capable of it but xfx and most others set to 1750 in the bios, I dont know anything about PBE but youtube may have a guide. I just restored his card to a proper working state.

ok I've done the mod. if you're on windows you need pixelpatcher

bios 1 is just moded straps. you need to set memory clocks in settings.
bios 2 is with 2000 memory clock.

also note to everyone... this is SP2048 cards not regular 580.

 

[mohanbrulz]

Thank you @atifsh .. I will flash the bios and revert with results. Meanwhile I was trying OC and UV.. the standard settings of mem2150/850 and core1150/900 doesn't work with this model.. max hash rate I could get was 27 m/h.. I have two cards and found it very difficult to arrive on average numbers for both cards together.. for a single card which is not primary I almost reached core1350/950 and mem2220/900 just to reach 30 m/h. Is this normal ? will my card get damaged at this settings?

Yes it is a RX580(RX570 OC'd)for china, also sub id has C580 in it

Hi @atifsh.. I tried flashing both BIOS one at a time.

BIOS 1 worked fine but with Phoenix miner was giving Incorrect share error initially. Tried tweaking mem to 2000. Max was able to go till 1790 and then GPU crashed. Final Hashrate was 25.5 M/H

BIOS 2 after flashing, the moment i opened the phoenix miner it crashed after few seconds. I didnt try changing mem settings.. was clear that the settings were not going well with the GPU.

Used pixel patcher both times..

Unfortunately both BIOS didn't help to achieve better hash rate. Still stuck with Max 25 M/H.

Flashed the stock BIOS back for now.

ok let me do another one.
forgot to tell you you most probably cant go above 2000 on SP2048 after bios mod.
I have XFX SP2048 580s but all are Samsung memory and they are stable at 30.5 and only on winters they do 31 MHs.
also doing anything other than 900 volts to core they crap out.

first try 1 if still fails try 2.

overclocks to test

1150 core
900 volt
memory 2000

do not try anything else

 

[mohanbrulz]

Hi @atifsh .. I tried all BIOS shared one at a time.

1-strap - Was giving 24 M/H without OC. Moment i changed the OC settings as suggested went upto 28 M/H and it crashed.

1-strap-memvolt900 - Was giving upto 26 M/H. The moment i overclocked to the said settings it crashed.

2-strap - Was giving 24.5 M/H without OC. When overclocked took upto 28.5 M/H but it is not stable and either one of the cards go to 28 M/H most of the times. I have attached screenshot below.

Also some black pixel flickering on the display could be identified and Temp was above 80 C.

Hope the settings is as you suggested.

2-strap-memvolt900 - Without overclock was giving 24.5 M/H. With the overclock comes upto 28.5 M/H but again it is either one of the cards most of the time. CPU temp is above 80C. Screenshot mentioned below for your reference.

Btw just for your info i am using the same BIOS on both cards with the same OC settings u suggested. Let me know if anything else can be done or this is the Max for this GPU.

I would be very happy if it stabilizes at 30 M/H at some point but with all the trials looks like there is no hope.

Thank you for your support.

your temps are the problem.

flash one of the bios with memory 900.
just use amd own tool and set fan to 80%
see what you get.
1150
900
2000

 

[mohanbrulz]

I tried with 80% fan.. Temps have come down but the hashrate is still the same.

I am unable to use the AMD tool once i flash any modded BIOS. The drivers are installed but application doesnt open unless i flash the stock BIOS back.

Hence using the Overdrive tool.

 

[atifsh]

what drivers are you using?
uninstall drivers and do a clean install removing everything. better to use ddu.
get the latest whql drivers from amd.

https://drivers.amd.com/drivers/radeon-software-adrenalin-2020-21.6.1-win10-64bit-june28.exe

download phoenix miner from here
PhoenixMiner 5.6d: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux) (bitcointalk.org)

flash stock bios on both of your cards and use this script in your phoenix bat file and run bat file as admin.

I've uploaded my file just in case. don't forget to change the wallet after testing.

C:\PhoenixMiner_5.6d_Windows\PhoenixMiner.exe -pool ssl://eu1.ethermine.org:5555 -wal 0x008c26f3a2Ca8bdC11e5891e0278c9436B6F5d1E.Rig001 -tt 65 -fanmin 70 -fanmax 90 -cclock 1150 -cvddc 900 -mclock 2000 -mvddc 900 -mt 1 -rxboost 1
pause

Hi @atifsh I tried performing the steps you suggested. I was using the original Radeon drivers which you have shared. I have uninstalled the drivers ran the AMD cleaner utility downloaded from their website from the link below

https://www.amd.com/en/support/kb/faq/gpu-601

Re-installed the drivers using the links which you shared and reflashed all cards with stock BIOS.

Ran the start miner file with the link which you shared but the display crashed and black screen was displayed.

Then i thought it could be coz i didnt switch on to compute mode so changed that and again ran the miner file which you shared. crashed many times at the initial stage but some times used to run and increase hash rate until 29 MH but unfortunately it always crashed in the end.

Running the stock BIOS without any OC for now

ok if its crashing with stock bios than there's something wrong with your setup.

unplug all card's but one and try.

also when you say you use bat file I've shared you mean you put it inside the miner folder correct?
make sure path in the file is according to where you have the Phoenix miner saved
also run it as admin ... right click on bat file and run as admin.

if this doesn't work than I can't help any further.
maybe try without rxboost.

 

[mohanbrulz]

Yes. I Put it in the folder and path everything was updated accurately. May be the way it's setup could be an issue. I will try without rxboost as well. Thanks for all the help

Hi there,

I tried modding this BIOS for XFX RX 590GME 8 GB FATBOY 2304 SP edition. The BIOS editor is not recognizing my BIOS. Could you please help me do it.

I am getting 7 M/H only.

Thank you in advance

first try with stock bios.
install latest whql bios
do compute mode
from amd settings
clocks 1200
volt 900
memory 2000 (or 2100 if runs fine)
Memory timing to 1
fans to 80%

it should be 24 to 28 MHs without memory timing to 1. after memory timing it should cross 30 Mhs.

if flashing bios do pixel patch new one before restarting.

 

[inarush]

@Freshbrewed thanks a lot for this writing up, really useful!

I have one question though: once I have found the optimal undervolt values (clocks and mV), how can I make the changes permanent?

I ask this because I have a Linux partition on my disk and I would also like if it could benefit from the undervolting changes on my RX 580.

 

[MacDe]

Hi Freshbrewed,
could you help me mod my 5600xt ASUS Tuf Gaming OC Cards?
I have one with Micron and one with Samsung memory.

Thank you very much in advance.

 

[EjMining]

I am a newbie at mining.
I bought few xfx 590 8gb(fatboy) Cards.
Are the bioses below modded for mining?
I will be running linux. Which is the best hash rate and can you give me some pointers to achieve this?

THe cards have micron memory.

Nice info.
I tried memory OC on a bunch of 570 (1750 to 2000) cards using the driver cpl and it somewhat worked, eth went from 24MH/s to about 28 until HWInfo started spitting memory errors, setting it at 1950 stops the errors and keeps the hashrate stable but for unknown reasons the cards will, at a random point, simply revert into "Graphics mode" and there's no way to return them to Compute without doing a complete driver reinstall.
I'd edit the BIOSes but honestly I can't understand anything on the OverdriveN window and don't want to start editing random numbers just for the sake of it because I know I'll brick it.

I'm just getting into mining, running 4 590s using the radeon control panel and work just fine, getting around 30-32 MH/s for each with Nicehash. The 570s are 4 as well but I have no case for them, don't want to get an open frame rig because I'm sure the fans will be covered in dust and cat fur in 2 hours.
