Repaired a Galax RTX2070 I received, which apparently had an initial defect

Hello, I'm Incompetent.

*I haven't studied any specialized fields in school or anything, and I'm just an amateur doing this by myself, so please don't try to imitate it.

This time, I tried to repair the RTX2070 I received from Kome-kun.

What's more, I also received two working GTX1080s and a Logitech mouse!

It's a secret just between us that I said the broken RTX2070 was what I was most interested in.

The initial operation test was done from HiveOS, and I thought it would work normally with "recognition OK", but then it stopped being recognized. Even after restarting, the display showed "MALFUNCTION".

Yeah, it's definitely broken.

So, let's start by disassembling it.

My first feeling was being intimidated by the number of parts, wondering if I could really do this.

First, I started inspecting the MOSFET part, which is responsible for power control and often fails, but there was absolutely no suspicious part...

It clearly worked fine at first and then stopped working, which didn't seem like a failure of the GPU core or NAND memory itself during that time, so I decided to look at the board around the power circuit coming from the PCI-E 8PIN.

Hmm.

Huh.

Huh?

Oh?

Doesn't this thing clearly sit in a way that deviates from the pattern?

Oh, it was you!!!

So, with this chip capacitor in place, it probably creates a short circuit, which would naturally lead to strange behavior, even for a chip capacitor.

Especially since it worked a bit during the initial test, then stopped, and then worked again after being left alone and reconnected, only to stop again, I thought there might be something wrong with the capacitors, but I never imagined a chip capacitor would be sitting in such an impossible position...

I used to wonder if initial defects really exist in this day and age, so seeing something like this made me realize they truly do (I'm convinced now).

So, I removed only the problematic chip capacitor and tested it again!

And so, it's working successfully! ＼(^o^)／

I believe the 0°C display is just because the memory temperature isn't being shown, so it should be fine.

So, being able to fix an initial defect junk item that I would have definitely given up on in the past feels really good and I'm in the best mood.

It's usually easier to understand when someone has used it normally and it breaks, as those are common failures, but with initial defects, I always thought it was entirely possible for something to be broken from top to bottom while looking perfectly fine... This incident has given me another boost of confidence.

Thanks to Kome-kun.

So, currently, I'm hooked on machine learning and plan to gratefully use it with CUDA in OpenCV.

However, I want to turn my unused Windows machine into a GNU/Linux machine, but not being able to use Adobe software is too painful, so I'm thinking I'll just have to build another one... (Due to my philosophy, I don't use Wine because it's not eco-friendly and I don't want to specifically run Windows software with it.)

I'd like to put a custom-built PC in the room with the sofa, but I can't run a LAN cable there, so thinking about buying a Wi-Fi card and all that makes it quite troublesome, and it keeps getting postponed.

And somehow, the SSDs I thought I bought quite a few of in 2023 are not enough (´；ω；｀).

There's still so much to do... Or rather, I think it's just right to have an endless list of things I want to do, so I'll take it easy and do what I want when I want to.

Well then.

I plan to post a New Year's greeting article later, but I wish you all the best for this year as well.
