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!
