Hello there, I hope you guys are doing well.
I have a couple R9 380 one is MSI and the other is Sapphire both are still with 4GB until now
I'm new to fixing up this kind of stuff, but I'm into learning new things. So i managed to get one card to my machine and did some initial software inspection I got to the conculsion that I have a bad RAM (three chips apparently are faulty) on the MSI which is a Hynix based one,
on the other hand I can control many aspects of the card, like voltage/clock/fan speed etc, but of course with a bad RAM i won't be able to see anything on the screen expect a black screen with some random stripe that is of pinkish/yellowish based color, I dont know if replacing these CH D0/D1/F0 would actually fix the problem of this card or not but i think for the learning experience its worth the trial, I do know that its not an easy peasy job.
or maybe all of what i figured out does make no sense at all and someone can shed some more light.
The Sapphire card is more of a story, which is elpida RAM based, this one gave some hard time to investigate and it barely allows me to talk to it, and once i do say something to it, my machine would hang and then my mother board will be flashing with qcode 8, i also tried all the available bios available on the internet (the ones i could find, maybe 7 of them) all the same result.
All my best,
ok the situation has worsened a bit with MSI card, I did a bad move, I just flashed wrong bios on it, and now its totally invisible for the machine, I cant see it, starting from BIOS up until linux..
I think I would need to short the reset PIN on the bios flash/chip to get the factory BIOS again or it does not even work that way
