Spent the afternoon cleaning and then repasting a GeForce 4 TI4600 128mb with a new cooler, however the GPU has what looks like a bad memory chip(s) on it, large square patches of corruption on an otherwise clear and viewable picture. Perhaps I need to reflow the memory BGA chips with a hot air gun or replace them. Unless another member has some insight as to other possibilities for failed components.
Either way the GPU is going back into storage till I have the time and patience to reflow it.
Shame too as its a nice looking GPU.
Knowing me ill grab another Ti4600 and this one will stay in storage 🤣.
One of those is buried around here somewhere. Back when they were worth about $5 working, I did a low effort dry reflow attempt with a hot air paint stripper, managed to damage some of the caps, derp, so caused myself more work, thermometer said I shoulda got it hot enough, but when caps repaired and re-installed it was just the same. Definitely the RAM on mine though, I could press on them and have the picture improve. Sometime I'm gonna come at it with a hot air pencil and flood under chips with flux to try again. My other thought is to cut out a couple of thick aluminum plates that fit on the RAM chips and use a small C Clamp to mush them into contact 🤣 (Or find slightly less clumsy way to screw it together and apply a lot of pressure)
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
