Asus X555LD onboard RAM disable
This guide is valid for Asus X555LD board. This board has various revisions and was used in several Asus models. I used X555LD Rev: 3.3 boardview for this guide.
We need this mod when suspect about onboard RAM chips. All onboard RAM chips must be removed. If client requires the onboard RAM, replace the RAM chips and shift back the resistors.
This will list all RAM configuration lines, PCBID1-4.
There are four (4) resistor pairs which need to change position.
Change position for R2141/42.
