Hey guys. Sorry to necro.
I have a Tri-X OC R9 290X.
I flashed both bios chips with a bad bios and now the card is not detected in atiflash. Yes I made a big mistake, it sucks.
I have just tried the 4 and 7 pin method and the 5 and 6 pin, on the 4 and 7 pin method, my motherboard would not start up with the bridge in place (regardless of the bios chip switch position).
I then tried 5 and 6 on either switch position (I have no idea which direction the switch is in corresponds to what chip on the board, if anyone knows that would be a big help), booted to atiflash dos, amd -i, adapter not found still.
I have yet to try the chip on the bottom (front) of the board, it's possible I have fried the chip on the back already because at one point last night (I was up 2 nights in a row trying to fix this.) I saw a spark as I was stupidly adjusting the bridge while it was powered on.
So, if it is burnt out, thankfully there's still the other chip, I just need to figure out a way to bridge them and keep the bridge in place what with it being upside down there. I'm not quite ready to try soldering yet, especially if the first chip is not burnt out and the bridge method is just not working for me.
These are my chips:
I know I have one of the pins wrong here, I corrected it before the attempt, but this is how I've been doing it:
Can anyone help or offer advice?
I have a ch341a programmer but not the right clip for these small chips on hand.
Someone on discord suggested this:
"so I think you will need to disable both roms with cs, then make sure the switch is in position for the one you want to flash / remove the bridge"
so do you think I might have to bridge both chips at the same time, boot up, remove one, flash it, done?
however if that is the case and you need to bridge both at the same time, then I would have to re-do the bridge on the fixed chip in order to get it to be recognized when on the switch for the second chip to be repaired, right?
Thanks again if anyone can help.
