Continued: Repairing RTX2070 GDDR Memory Error by Resolving a Short in the Memory Power Supply Section
Hello, it's the incompetent me.
It was the RTX2070 that I was supposed to have repaired last time, but it was still no good.
The thing is, it worked normally when I first turned it on, but after running it for a while, it would stop working.
This is strange; when I remove and reattach it, there's no memory error only at first, but when I boot the OS, noise appears and then a memory error occurs again.
The RTX 20 series seems to be known for a lot of memory defects, but I'm not convinced. That's because if it only works normally at first, it means the memory is working correctly during that period.
So, I'll hypothesize that there might be a problem in the part that generates the memory power and examine the board.
First, check for memory errors.

My desktop being messy is a usual thing.
Install NVIDIA MODS on a USB drive and boot.
cd 400.184
./mats -e 15 > test.txt
The test starts here.
less test.txt
And, it showed the image above, and when I checked the results, I confirmed that there was a memory error.
Oh, is something wrong here?

I apologize, but the above image is after the replacement has already been made.
While measuring the resistance around here, I found only one that showed continuity. In other words, I judged that if it's a resistor but shows continuity, it must be a short circuit.
Since the resistance values are properly displayed when measuring resistors around here, I embarked on a journey to find a chip with a similar resistance value.
With a multimeter in hand, I looked around at junk boards.

Found it! This one is...


It's the P8Z68-V/GEN3 that served me well until last year.
I'm sorry... But your life will live on in the RTX2070...
So, I removed it with a soldering iron, and while my hands and eyes were almost dying from soldering such a tiny spot.


With this, it is now possible to load the OS successfully.


Yeah, it's working normally!
Done!
