I cannot install driver in windows (error 43 even with patch) in hiveos also unable to see the card ( problem resizing baro -22). tried different bios, programmed with ch341a => same result

card details:
Sapphire pulse radeon rx 580 4G gddr5
sku: 11265-09

original bios here: https://easyupload.io/48phuh

Hi, before answering i have tried to write the flash using CH341a. Flash process was successful, however i had the same issue or gpu initialization. I tried to see if it works using hiveos.

I can post a picture with the card, or i can post original bios here, maybe someone with more experience could take a look.

hi,

is not working, i receive an error on gpu initialization

Thanks bastonxl. I will try this option .
Possible stupid question: is there a significant difference between flaahing using atiflash and using ch341a?

As i stated, it was an experiment. that 580 was getting dust in my closet and the chips i received for free. the only cost was the soldering itself, and was not expensive. I want to make a kind of proof of concept.

From my research i found that in some cases, the board is the same for 4gb and 8 gb versions of 580, hence the testing moving forward.

I also think that the issue could be 50% related with the bios setup (timings and other parameters) and 50% with the hardware (board) itself.

Before the testing, i assumed that something could go wrong, but was a calculated risk. My focus now is to narrow the issue root-cause, and test proposed solution from guys that are having more experience than me on  bios customization and hardware knowledge.

Hi hagbase,

done that, no change

Hello internet ppl,

Let m tell you a interesting story, maybe you could help me somehow:

I did an experiment, replace the memory chips from an rx580 (K4G41325FE-HC25 - 4 GB) with some new one K4G80325FB-HC22 ( 8 GB) aiming to increase the physical memory of my card from 4 to 8 GB. The soldering part was made professionally.

After this procedure, windows is seeing my card however i receive a code 43 error (Windows has stopped this device because it has reported problems. (Code 43))

I thought that this is something normal, since the GPU has now different memory chips.

I tried all the bios found on techpowerup, change the timings, research on the internet, call some friends, but i was unable to receive a valid opinion of a possible solution for this issue.

Below are some print screen from meminfo, gpuz and current bios that is on the GPU.

If anybody did this type of experiment and manage to figure it out how to resuscitate the GPU after the intervention or have any other idea on what should i do, please leave a comment.

cheers!
