Nice work. Have you tried it on 5600XTs? Curious if it could pull some extra juice out of it.

Mircons and Samasungs can reach same performance.
You have to use correct timings.

I`m using RedBiosEditor to change straps.
Using TRM B mode i`m getting 53Mhash @100W on the wall.
core-1200@730, mem-880@1300 - All samsung memory.

Microns are different - 56Mhash, core-1400@780, mem-912@1280 - ~135Wat on the wall - depending on brand.

I literally had a crash after this post. Luckily I caught which GPU hung up when I found it. I think that particular card the natural voltage of the silicon is too low. I did see someone on youtube mention 800mv was a nice target with a bios mod. I was adjusting by reducing the core to a desired number, but I will try voltage now.

Boy am I glad I found this thread and gave it a try (so far).

So far I am stable for 10 hours, which has really been my biggest problem with my 5700's running on the stock bios.

I scratched my head for quite some time on this. It wasn't until I mined with lolminer that I saw the memory temperature was over 90C even though the standard temperature reading was about 60. So, I have a situation where I have 2 low end 5700's and then a higher end 5700xt and 5700. The low end GPU have the memory that runs hot. This seems typical of AMD if I recall I had the same issue with Vega. The 2 poor ones limit the system with crashes.

Back to the Bios. So, far it looks like it allows me to undervolt more and still maintain a core clock. I could not undervolt as much in the stock setting. Also, the hash rate went up about 8-10% and power down by 60-70 watts. Max temp of a GPU is 56C, which seems reasonable.

So, with 4 gpu I am at 210MH/s, 470-480 watts. I am not messing with memory at the moment because I have enough stability issues. There is a chance I could OC memory on the better GPU later on.

Anyone has the numbers for modded RX5600XT ? Seems like RX5700 now shortage in market.

did you mod RX5600XT and it is hashing 52mh/s?

I asume you have bricked card with incorrect bios, just reflash back to original.

Thank you very much for this article.

I will try 5600xt to run 52m-eth

Has anyone been successful in lowering the power consumption below 125 watts from the wall (using meter to measure not software) after flashing new straps? 

Hi,
I extracet the 1MB bios of my 5700, mod it with hex editor coping 1550 straps to uppper.

After flashing and reboot I have code 43 Error (unsigned driver?)

Tried atikmdag-patcher.exe, doesn't fix it
Drivers used AMD 15/11/2019 26.20.13031.18002

Any help would be appreciated.
Thank you.

Have anyone tried to mod RX5600, curious to see what are the results?

Appreciate the response.  My mistake was after extracting amdflash tool, I moved the entire extracted folder to C drive flash folder.  I need to pull the files out of this folder into the C drive flash folder  So worked there after

You are trying run amdvbflash but you are probably not with cmd where is your amdvbflash located.

To fix this just open folder where you have amdvbflash and copy path for this folder, go back to cmd and type cd "your path", it will looks something like this "cd C:\Users\Home\Desktop\flash"

then try to run amdvbflash -i and it should work without a problem.

Downloaded all the proper software to complete this flash   when in cmd window I complete the following commands and get this error...

cd/

cd flash

amdvbflash -i

then I get this error:  'amdvbflash' is not recognized as an internal or external command,
operable program or batch file.

How am I messing this up?

Would not pulling the files out of the extracted folder cause this issue?

Yes if you configure it right there is no real power increase, just hashrate.

I'm running 58.8 vs 53.5 at the same total power draw from the wall.

So, I had a 10% bump in hashrate for next o no extra costs.

Mod needs more cclock thats why consumption more. my findings just %2-3 more consumption %7-8 more hash ,so it's good at all.

anyone tried 5500 and 5600 yet?

This mod is only good for those with free electricity like myself, I find the power usage to be way higher which makes the mod not that great, if there is a way to lower the power then please drop

Hi! Great result! What core clock and core voltage? Are you sure "frow wall"?

What i found out seen some guys where getting incorrect shares, this is due to timings are different in different cards.
I replicated this issue with RX5700 MSI evoke http://prntscr.com/rc2j66
To fix incorrect share issue i used 1800mhz straps
Was not able to achieve 58mh with these straps, but 55mhs at 120w from wall stable

I think it is achievable currently running 3 cards and watt meter on wall showing 470w, so it is about 140watts per card +50w cpu
What i see really strange with these timings, is that hashrate increases significantly only when i increase core clock, memory clock does very little changes. I can leave it under 920 and core 1400 they get hash 58mh/s

Mineshop, id be interested in what the console miner shows for your pool side hashrate?

So far, I'm about 10% low but it's a super small sample size.

I've done nothing in terms of power yet - but I can say I've been running for 2.5 hours without a rejected share.

I need to allow it to run over night and see if the pool actual gets what the miner is saying it should get...

I did see roughly 20w increase in power.... But, I also have one card running at 900mv.

I will wait anxious to see if you can reduce the power usage
If you reduce to at least 10% (13w) and with the 10% of speed increase you already achieve, it will be AWESOME, and the card will be the best hashrate per watt

Cool great it worked out, im hashing quite stable. Will try to modify power usage tomorrow http://prntscr.com/rbpoh8 1 incorrect share in nearly 8 hours and 1070 valid

I may have figured it out.

Flashed back and was still getting rejected shares.

Then realized I was still using 4.7, upgraded to 4.9 and so far so good.

try Core 1300
memory 1850

Perfect thanks flashed and mining now 57 mhs

I have all 4 reference 5700 cards flashed to XT and mining around 55mhs. any advice to get them to 57-59?

57/54

What speeds you where getting?
I think you might need different timings , you can try to copy 2nd last to last.

I flashed back as I couldn't control the incorrect shares.

Hi,
I have 731F Navi10 GD25Q80C 113-R_170_XL_NAVI  (5700 non xt) with romsize 1MB, seems RBE can't edit 1MB romfiles. I should edit downloaded 512KB and force flash? or wait RBE update?
Thank you

1850 was bad too... Dropped to 1825.

I dont have any of these gpus wouldn't be able to to tell.

I think there is bug in software , when you save it is actually edited. When you reopen , it shows edited timings but when you click on it it shows previous timing. But the saved file contains actually your edited timings. Tried this myself and replicated your problem. Did you upload edited timings to your gpu. 2nd set of timings was for me that increased performance significantly.

Shappire Pulse 5700xt and Shappire Nitro 5700xt

I recorded a video with the process, and when I reopen the rom with the modified straps, they are the same as those in estock rom, do you know what the problem is?

What GPU do you have?
Invalid shares are usually due to invalid timings on gpus , if you get them after modification.

Woke up this morning to majority of my shares being rejected.

I'm assuming this was because memory was set so high (1900 mhz) I pulled it down to 1850 (925) to see if this helps.

I have 10 pro .
If there is 2 bios on card save after each edit, my did not work also when edited both at once.

How about the power consumption?
How much power are consuming on the wall?

waiting for PBB or SRB The program does not work well.

Video https://www.youtube.com/watch?v=zCs0QqZQmNg

I have followed the steps and is not able to modify the timmings

load the rom. copy 1500mhz to lower 1850 like polaris cards and save the rom.

I open the program again and load the moded bios and.. surprise, the straps have not modified,
It has the same as stock rom.

Works really great, thank you. My cards 70 hashing now 57.5, took me almost 4 hours to modify all of them. Worth every minute.

Settings:
Core - 1400
mem - 930
Volt - 800

I reviewed the rom and found one of the timings didn't save. So, I updated again and flashed it again.. With new drivers, I seem to be hitting 56 mhs now, running memory at 1900mhz, core at 1300.

What are your settings?

I didn't have any affect with drivers, tried Windows and HiveOS . Got same result , about 58 mhs. Check if you are uploading corect bios, and if the timings are edited. Cause the timing edit tool sometimes didn't save my room file properly.

So its safe to say this can also be done on an 5700XT version... Just wouldn't have to download the bios correct?

EDIT*  I just watched the video.  so know my answer now.

Thx

I flashed one of my cards - but no increase in hash. Do the drivers need updated?

Seems like the "flasher" link is broken.

Tested it while back, it's useless. 50% incorrect shares.

try -GT 151 -openclLocalWork 64 or 128 -openclGlobalMultiplier 4096 in PheonixMiner for 65+ mh/s. It's not fully stable but fun to see!

Well every card model is different , rather make your own. Dont want to brick your card...ha

Yes as there is power control tool also available, didnt have enough time to test it . But sure will update if will get some improvments.

Yes XT bios unlocks better OC to the card, seemed more stable and better speed increase.

It's very nice, great improvement, just one thing: do you think that there´s a way to decrease power usage?
It seems very high

Better to share just micron and samsung straps..moded my ref 5700 bios but just increased 1mh, soon will try 5700xt bios.

Come on dude don´t be lazy. I think you have no idea what you have to do 

can you share the customized XT rom with us lazy folks 

Up until now there haven’t been any handy tools which would allow to edit AMD RX5700 graphic card bios timings. Timing editing for AMD has worked very well in past and increased mining speed by 10%. The same is possible now with RX5700 gpu. We have tested this and it is working fine, we have increased mining speed from 52-53mh/s out ff the box up to 57-59mh/s.

This is very important, even more when profitability is very low. Here are the steps we did:

Tools needed :

✔️GPU-Z – https://bit.ly/32LonaI

✔️flasher – https://bit.ly/2TlZlMl

✔️BIOS editor – https://bit.ly/2IcYNSC

✔️GPU BIOS collection – https://bit.ly/3crXCfV

So for test purpose we have had 2x RX5700 non XT version. We have edited timings and also upgraded nonXT version to XT.

Follow the steps:

Download you gpu bios to backup with gpu-z


Extract flasher to your C: drive


Download Original XT version from GPU BIOS collection


Open XToriginal.rom with BIOS editor and edit timing straps and save bios in your flasher folder. Straps edited copy 1500mhz to lower 1850…..etc (similar way as RX570 4gb cards) . These cards does have 2 bios, so edit both of them, after each time editing you need to save. This tool doesnt allow you to edit 2 bios at the same time.


Now you need to upload these to your graphic card. Open command prompt as administrator . Navigate you you flasher folder  (cd => cd flash => amdvbflash -i ) this will give you information of the gpu connected in your system.


Next you need to unlock gpu ROM to upload new BIOS type in cmd( amdvbflash -unlockrom 0 ) 1,2,3 if you have more then one gpu


Last upload new BIOS to you GPU type in cmd ( amdvbflash -p -f 0 newBIOS.rom ) newBIOS is your saved .rom file name


After flashing, the computer must be restarted. We can already admire the new data in GPU-Z. In this case I had set the boost clock a bit higher. Now the value is no longer 1925 MHz, but 2104 MHz. In real terms the card reaches 2050 MHz with the right cooling.



Easy as that, reboot your system and your hash-rate should increase. If you have done everything explained here. Other flasher versions wont work , download links provided on top of the post.
