Topic: Modified GPU BIOS for Mining - page 12. (Read 31041 times)

The sensor is attached to the GPU but it's the memory that overheats.

I'll be modding some new cards in a few days and I'll do all your bios requests while I'm at it...

Yes if you do like this example below you will do.
1. Download Polaris Bios Editor 1.6.x and above versions
2. Download ATIflash 2.77 latest version, or if there is a new one, download the newest.
3. Download Atipatcher.

How to bios mod with the simple method.
1. Open Atiflash as administrator and save the original bios of the card, name it "original.rom"
2. Open up Polaris Bios Editor as Administrator, click open and load the "original.rom" bios, once loaded click ONE TIMING PATCH
3. Save this new bios with a different name "moddedbios.rom"
4. Fire up again Atiflash as administrator and click LOAD this time, load the "moddedbios.rom" and then click PROGRAM or PATCH(usually is PROGRAM) the command at least in my version is PROGRAM.
5. Wait 2 minutes after is done the flashing of the card and then restart your PC.
6. After restarting your PC run Atipatcher as administrator and patch found values, click OK.
7. Go to MSI afterburner, put core clock 1200 and memory clock 2100, a card with Samsung Memory should even go up to 2250 as memory clock but try slowly starting from 2100 until you have found the limit.

RX 580 8GB Samsung Memory will easily do 29.9-31.6 Mhash on Ethhash.

I would have mod the bios for you but no RX 580 available to use so I can't. Anyway if you follow my above tutorial there is 0 chance of error.

Always Blockchain driver with modded bios cards otherwise MSI Afterburner will not recognize core clocks and memory clocks of the cards.

So is it normal that by the "quick'n'easy way" of bios modding I can only achieve about 29,4 mh/s with those cards on ethash?

Thanks in adv.

I would like some help with my AMD Sapphire RX580 Pulse 8GB to use it ETN mining ( cryptonight algorithm )

Link to my card -> https://www.techpowerup.com/vgabios/191713/sapphire-rx580-8192-170324

Link to my stock bios -> https://mega.nz/#!YmYVhDRa!5syRQ0Z-BCmlhAvSGCBrnWiQCg0UjyydNw_cmR3wCfQ

I would also like to ask you after the flash of my GPU , will be there any consequence in gaming ( spefically pubG ) ??
In addition , if i would like to flash my GPU into default , the only thing i would have to do is to download its BIOS from the official site?
Or i would have to do something else?!
And lastly , overally , what are the risks of flashing that way ( flashing customly ) my bios ?!

Thaanks in advance!! ^_^

Having issues modding my Sapphire RX 480 Hynix 4GB version, can get it to 680 at max but nothing higher.

Able to shine some light on it?

is below 60c

Asus rog strix rx580 8gb Samsung x12
Xfx rx580 8gb Samsung x10

^^^ probably overheating, set fans to 100%

Hi,
Do you have any idea that why hashrate drop once in every few mins and it goes back to normal? im on multi gpu rig 12/10 gpu
Mining eth
will upload my bios for you to take a look later
Thanks

Since there was much talk about AORUS RX580 8GB - Samsung mem. and apparently no modded BIOS. I'd like to request a mod of this original BIOS https://drive.google.com/open?id=0B9Fp674fU1OfRmpweW0xWXkyODZPWnF2ZW5FNlRtcmppaktr

Same stats but it works without needing pixelpatcher.

Hi!

Any chance you take a look at this model and optimize it?

Thanks!

no

@nobatman
I tried your bios for a while and saw the high temperature of 2 cards with 60c and a card with 65c
i set the fan 80-100% and it ran 70% (gpu_z)
Then I tried the tool xmr_stak_amd(of nicehash) and found it ran at 347-350 / s but the temperature was lower than the claymore about 5c for each power card is also lower
And there is something interesting when i try to use msi_ab set core at 1024 speed does not change and the temperature continues to decrease
can you help me again with better bios using with xmr_stak_amd
i'm really sorry to bring you troubles
I have a plan with rx560 so I try to run it as stable as possible, where I'm at rx470, 480, 570, 580 cards are expensive to buy agents and a card that can almost buy 3 rx560 card so i plan to set up the rig with rx560

A good step, and exemplary, by directly practicing it then we will be able to know what obstacles and problems we face when we assemble / modify the GPU BIOS for mining..

i'm doing test your bios
first i'm intall Adrenalin drivers 17.12.2 and use claymore 11 my it run at 364h/s/vga
but i offen use nicehash miner( for vga & cpu E3-1230v2 220h/s) and it can't detec my vga
then i try intall Adrenalin driver 17.11.4 and use claymore of nicehash it run 374h/s/vga
i run it 3h ago, just waiting and hope it run stable
thanks u alot for everythings
p/s: someone say with me use nicehash miner is enable xnsub, if only use tool it don't enable xnsub, that's right?

Do you have a mod for Msi rx 570 gaming x already made?

Cheers.

^^^ Koreans are awesome, Samsung makes the best RAM IMO.

@notbatman.

Thank you very much for the Sapphire RX480-8GB-Samsung Bios! It boosted my hash up to 30MH easily! Awesome work.
I have another old rig with Sapphire RX470-4GB-Elpida, I tried applying your Elpida memory timing but the best i can hit is 26MH.
Elpida supposed to be the best ram available, that is what I read.

Can you please have a look at the bios I tried using your guide? Running 975C/1850M/800mv settings.

Oh that's bad to hear that you need the card at your place to do the mod, but I guess otherwhise it won't be as good.
Thanks anyway
