This was actually yesterday, but I only got to post this today. Finally received the Nichicons, and proceeded to install them on my boards.
First was the ASUS A7N8X-E. It was a tight fit, because the caps are actually shorter and wider than what normally fits in that board, but they got in, and I made sure to put them reversed, because apparently ASUS can't silkscreen for shit. However, the result was actually worse: the CPU fan spins at full speed for 1-2 seconds, and then it shuts down. Weird, at least when I had the wrong caps in the wrong way it stayed on...
Next was the Abit-KD7. The caps fit just fine, but there was no improvement on the board, but I think it stayed on for just a little bit longer. I also noticed that even the PSU Fan had trouble getting to spin when hooked up to this board. I think I'm on to something...
Last was the Gigabyte GA-K8VT800pro. It was a tight fit. but that one worked just fine. It didn't really have any issues with the Samwha RD caps (not yet anyway), but I figured I would do it right, since I got 30x low ESR 6.3V 3300uF Nichicons for that reason. Anyway, I expected it to work after replacing the crappy caps, and sure enough, it did. Unfortunately, I noticed that one of the tabs for the heatsink had broken off, so it's unlikely that I'll be using it any time soon. I just can't have a working AMD system. Shame, because I really want to build an AMD based system, but they never really work properly. It's not even because of AMD! It's usually crappy boards, capacitor plague, fried VRMs, cracked/chipped CPU dies (I once did that myself by accident, I blame that on me) or corrupted BIOS chips (need to get myself a BIOS flasher)
I also found a laptop. A Toshiba Tecra A4 PTA42E. It's a good thing the courier didn't bother to actually send the caps to my home 🤣
Anyway, I proceeded to diagnose and service it. Its HDD is toast, but the GPU is actually fine. I also upgraded the RAM to 2GB and the CPU to a Pentium M 770 from 512MB and Pentium M 750. It still seems to not work properly, but I'll figure it out.
