You must flash bios to 8g using ch341a or similar supported bios flasher.it will not flash bios on mobo. Get from techpowerup samsung bios. 1st try same brand bios samsung 8g it should work. good luck

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

There is no difference. atiflash you use when your video card is working, If your card is not working, then you use the programmer.
Many programmers have special adapters that allow flashing a BIOS chip without soldering.
If the BIOS firmware does not solve the problem, then you need to look at the jumpers on the video card, which may be responsible for the memory size.

Could be more than changing the memory chip only mate, why engage in such way if you have no idea about it in the first place? It's why I don't listen to people who gave me such idea to buy 8gb memory and insta on 4gb rx570 of mine, the memory are costly and the chances of making it work is very slim

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.

Moving 8gb memory chip to 4gb gpu board of rx580 might not be the only thing to change for the 8gb to start working, gpu manufacturers are not stupid, there might be some limits on the 4gb gpu board, like empty capacitor fields or even resistors

Did you try https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher
Was using this after modding VBios and getting Code43.

Hi hagbase,

done that, no change Sad

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!
