![]() My mission of learning to desolder and resolder would be a complete success at this point.ģ) If that fails, wait for replacement chips to roll in and try to program them, then solder them.Ĥ) If that doesn't work, I'll have to go beyond the scope of my learning adventure and will have to get into "hacking" the programmer. ![]() ![]() If this works, I just need to resolder and repeat the process a few hundred times until I get the right BIOS. I read on this forum someone was able to read the chip only when desoldered. I don't understand it well.Ģ) Try to read it once desoldered. I'm not sure if that'll make it a 3.3v programmer. If I understand it right, I have to desolder PIN 28 from the programmer chip, lift it, make sure it makes no contact with the board, and connect it by wire to 2 other "ends". I also do not understand how to bypass the 3.3v regulator or whatever that was from those articles. On another note, I have no electrical experience, so I don't know how to test for shorts. I'll just be sad I failed at this new experiment, but that's it. Thanks!!Ĭlick to expand.I knew I should've waited for a reply before buying more stuff from Amazon, ROFL!Īnyway, that GPU is useless with its fake Chinese BIOS, so if I destroy it even more than it already is, I don't really care. P.S.: As for the card itself, it seems to be a 768MB card. I always thought I was doing something wrong since I'm not pro at this stuff, but I think at this point I need some help in figuring out why this card immediately burns out my programmers.Īnyone have any clue and how to fix it? Please let me know!! After that, they're not able to ever read again (tried it with the other card that didn't give me such problems). Hands on experience FTW!Īnyway, I lost 5 programmers to this thing, and it seems that as soon as I connect the programmer to the card's chip, the programmer overheats. I had spent a lot of time and programmers on this to gain some experience on the matter. Lately I decided to go back to this card and try to make it work. I was using a ch341a programmer to flash the BIOS, but when attempting to read the chip from the bogus card, the readout would either be gibberish or empty. A long time ago I bought some bogus cards from Ali Express and with the help of this forum I got one of them to run, but I gave up on the other because I couldn't get it to work at all.
