Replacing ROM chip

post #1 of 2
Thread Starter 
Hello OCN, due to a recent turn of events I've found myself with a bad flash and a bricked ROM on my 5770. I'd like to desolder and replace it, but my only ROM chips on hand are from a different manufacturer. The sizes are the same (128K), but I'm loathe to experiment with soldering as it becomes exponentially more difficult with each desoldering.

Has anyone experimented with replacing a ROM chip with one by another vendor?

Thanks again, OCN!

Edit: I've confirmed the ROMs are the both 50MHz. Given the similar memory capacity and frequency, is there any reason I couldn't swap them? My main fear is a different set of pin-outs.

If you have another GPU, try Blind Flashing the ROM first.
