Help with disabling onboard RAM. Lenovo ideaPad 3 17IIL05 ( Board DM-D031 ).

[SonicSkye]

First, I want to thank anyone who has taken the time to look at my post.
I have a Lenovo ideaPad 3 17IIL05. Board ID: GS454/GS554/GV450/GV550/HS750 Rev 1.0 NM-D031. Intel i5 (10th gen) with 4GB onboard SK Hynix modules.

• I've found memtest86 v11.5 is showing the onboard RAM is failing.
• I've attempted to use the following schematic to disable the onboard RAM: nm-d031
  • I moved resistors RC826 to RC839, RC827 to RC840, and RC828 to RC841.

The problem is now the board is identifying the onboard RAM as Samsung modules instead. Meaning I must have goofed something, or horribly misread the schematic.
I've attached photos of the board info, RAM modules, and the current layout of the resistors.
If there is anyone who can lend me a helping hand, I would be extremely grateful.

-Thanks again for your time in reading this.

Wait... Hold up... after walking away for a bit and then looking at the picture I posted, I think I realized where I went wrong. I think shouldn't have moved RC827 to RC840. I'm going to do one last check before I move the resistor back over.

P.S. I've attached the boardview file I've been using here, as I neglected to do-so in the first place. 😅
P.S.S- Thankfully the 15" & 17" are identical boards.

I feel I should clarify that I wish to disable the onboard RAM to make future repairs easier for the next person who may need to repair the laptop. Plus, I don't have enough confidence in my limited tools to replace the failing VRAM.
I know that I could flash a BIOS onto the system that would disable the RAM with far less effort on my part. However, this will not be my laptop after I am finished with it. I'd rather the next person not deal with the problems that would arise from them (or Windows Update) updating the BIOS.

Welp... This is one of those, "this is what happens when you keep pushing yourself with no sleep", kind of situations. I just misread the schematic and swapped a resistor I should have left alone.
onboard RAM is disabled, and I'll be able to donate this guy to our local Community Aid.
