BIOS modified RX5700 | how to edit timings | 10% speed increase.

[mineshop.eu]

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

55mhs at 120w from wall stable

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

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

anyone tried 5500 and 5600 yet?

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.

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.

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

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?

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.

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

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

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.

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? 

[skygonga]

Thank you very much for this article.

I will try 5600xt to run 52m-eth

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

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

[YourKarma]

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

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.

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.

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.
