Hello and thank you for everything. Currently, I have a 5600XT in which I have flashed the modified bios by Red BIOS Editor. However, the BIOS did not work, the system hangs during POST. This is no problem, I am used to flashing BIOS with SPI Programmer CH341a, I am free to test anything.

I think maybe this did not work due to the fact that my card is dual BIOS, and when I read the BIOS from the memory chip, it comes out with 1024kb, rather than the 512kb saved from GPU-Z. When I try to open this extracted BIOS with RBE, it modifies fine, but does not save by stating "An unknown error occurred when accessing (filename path). This is not a permission issue, I am running admin. It works fine to save the file when I use the GPUz extracted rom. However, even with the 512KB file, it does not work to post the card.

I have tried several things, the last one was to make only a very small change on the GFX Maximum Clock to 1900MHz. It still does not work. I originally made a BIOS with a lot more changes and limits, such as 2100, 1000 memory, more power, voltage, etc, etc. but decided to make a small alteration to see if it would work-- unfortunately it doesn't.

I have also tried to open in HxD the original long file 1024kb and noticed it makes no difference, because after 000FFFF0 it is only 0's anyway. Also, in HxD, I have tried to open the original stock BIOS and overwrite the part, leaving the correct file size, but this also did not work to POST. Stock BIOS still works fine when re-flashed, card is perfect.

So, I am leaving a link to my files, to see if we can figure out why the modified BIOS is not working on my 5600XT.
Here is the URL: http://xonedigital.com/BIOS_etc.zip
on this ZIP file, there are the following:
1 - 5600xt1_gpuz.rom (Original BIOS from the card extracted with GPU-Z)
2 - 5600xt-stock_extract.rom (This is the BIOS file extracted from the Chip with SPI Programmer, it loads on RBE, but fails to save)
3 - mpt-1900_only.mpt (This is an example of a small change I tried to see if it would work, only changing maximum clock to 1900mhz)
4 - 1900-ONLY-BIOS1.rom (This is the final outcome of RED BIOS EDITOR using the GPU-Z BIOS with the MorePowerTool settings of 1900mhz)

I hope this helps, thank you so much for all your work again and let me know if anything else is needed. I am really looking forward to free up the power of this 5600XT :)

Thanks again!

I have tried now bios mod with

- Under Feature Control, set:
DPM_GFX_PACE: Check (Enable)
ACDC: Check (Enable)

and other settings suggested on page 7.

I get exactly the same hashrate than before (43.8 MHs) at same watts power consumption... I can't say anything about stability yet...

Unfortunately as mentioned before, there is a bottleneck set inside the vbios and some cards vendors even set security to prevent modification for mining, I believe AMD do not want the 5600 XT to be used for mining, imagine if we managed to make 5600 XT produce hashrate more than 50 MH/s, what will happen? No 5600 XT on the market anymore and 6000 series sell will fall drastically.

Hi @ricardo
I was looking for a way to fix a RX 5600XT Asrocks Challenger Pro as I bricked it with Red Bios Editor and now the PC doesn't POST. I ordered a SPI Programmer CH341a and I would like to ask what software did you use and how you connect the programmer. I do have the original ROM which I saved before editing the BIOS.
Thanks for helping me :)

Hi and welcome,

I would like to confirm something, did your order the SPI programmer because you do not have a second gpu at hand or your cpu does not have an integrated gpu or something else?

thanks @Mini_Me for unlocking my bios, It's working flawlessly.

memory on my 5600XT clocks really well, I'm running the core @2000MHz and the GDDR6 @1924MHz, using 1.043V.

the boost I neede to keep CP2077 stable on 60fps

THANKS

Hi Mini_Me
Can you unlock my Bios? Is from an Asus Dual TOP 5600XT. I use the GPU for mining. Thanks!

Hi I've been searching and reading this thread and finally was able to get a couple of Sapphire Rx 5600s. Unfortunately I couldnt get it to post after bios modding using amdvbflash and modifying timings at RBE. Both the silent and performance always on black screen after boot up. Tried everything using others bios and from techpowerup too. Can you please help? Much appreciated and Thanks in advance!!

Due to 1x8pin power connector, I believe for 5600 XT and best power table is as below,

- Under Feature Control, set:
DPM_GFX_PACE: Check (Enable)
ACDC: Check (Enable)

- Under Overdrive Limits tab, set:
GFX Maximum Clock 2100 MHz
Memory Maximum Clock 1000 MHz
Power Limit Maximum + 25%

- Under Power and Voltages, set:
Maximum voltage GFX 1100 mV
Maximum voltage SoC 1100 mV
Minimum voltage GFX 800 mV
Minimum voltage SoC 800 mV
Power Limit GPU 180 W
TDC Limit GFX 168 A (or 186 A)
TDC Limit SoC 12 A (or 14 A)

[TDC Limit GFX & SoC of 186 A and 14 A are for those who have power supply unit PSU at least 600 watt gold rated]

- Under Frequency tap, set:
Memory DPM 3 - 900 MHz

When using AMD wattman or any other program use the setting for best stable performance to temperature ratio and it is important when undervolting to not let the ratio between core clock and vdd exceed 2, for an example, 2100 MHz ÷ 1050 mV = 2,

Core clock, VDD
2100 MHz, 1050 mV, for max safe undervolting for max performance,

Memory clock, 1820 MHz (Samsung and Micron) for best temperature to performance ratio,
or 1870 MHz (Micron) for best performance.

Apple Inc. optimized memory timings in the kindly attached link below,

what's the average hashrate?

Hi and welcome,

Are you going to use this vbios for gaming or mining?
