Guide Wii Trim Resistances

[Lemoncake]

hello everyone

can anyone help me?

Are these values okay?

thank you.

I think something might be wrong with your 1v line, because all of the values it gives are super high. This might not be the right advice, but maybe another round of sanding would solve the issue? Also, did you make sure to tape up the CPU/GPU/other chips while sanding? All the other values look good though, nice work!

Looks good to me

Hello, thank you for your response and the advice.

I used a lot of transparent tape to make sure that no dust or pieces of copper would get in anywhere.

I cleaned constantly at each step of the cut and replaced the tape every time I sanded one side.

this is My second attempt at trimming a Wii so I'm doing it very carefully and leaving more cutting room for errors.

I will try to verify everything again with 200 sandpaper.

I just realized that the cables behind me may be causing false contact, I'll remove them and see what happens.

Thank you.

Hang on, that’s my bad. I just saw “CPU 01” and assumed it was a 6 layer board. Those values are actually look really close. I wouldn’t bother resanding if you haven’t already, so sorry for the wrong advice.

These are my resistance values. when I tested on the points other than ground, they seem to be pretty low as you can see. Did I not sand enough, or is there another issue present.

Hello, I searched on bitbuilit for the resistors of my card, but I did not find them.

here are the results between the tensions of my wii. Is it good?


the model: RVL-CPU-60.


I will also post photos of my cutout below

I'm not sure, but the resistances between rails are definitely much lower than they should be.

I confirm, my motherboard is functional

Hello! I am doing my first wii motherboard trim and I get some weird values on the multimeter. The motherboard is RVL-CPU-50 with a OMGWTF-ish trim (I was a bit scared of going too deep into the board, could this affect the values this much?) Are this values ok-ish? Should I try to hook it up to power? Thank you.

The snags in the trim line are not ideal, but your resistance readings are within acceptable bounds. The board should be safe to use as is, but you can also sand it down smaller if you want to.

How low can i go on the ragged side? I am already pretty close to the trim lines here https://bitbuilt.net/forums/threads/the-definitive-wii-trimming-guide.198/. How much is it safe to sand down?

Also, I hooked up the buck regs to the trim (only the + terminal) and checked the voltage with the multimeter, should it be above 2v on the 1v and 1.15v terminals? (I am guessing the layers might touch or is this normal?)

That is very much the wrong thing to do. If there's no GND path for the voltage to return through, they won't read corrrectly and could damage the trim.

You can check regulator voltage without a load, so disconnect the regs from the Wii and check them that way.

About this close

That set of traces that comes out the side of the NAND chip are the important ones. You can go up to the thick GND stripe separating it from the next set of traces if you need the space.

Could someone tell me if this will work? It was done with the multimeter in automatic mode.

Your trim lines and resistances look good

Thank you very much. I hope I can try it soon
