According to your schematic, you need to add (3) 0402 resistors each one is (10Kohm), RC812,RC805 and RC811.
Also you didn't mention your onboard ram type and size.

Hello, thanks a lot for your reply.
Laptop has 4gb ddr4 onboard ram:k4a8g165wc-bcwe.
So i just need to add those 3 resistors and do not need to remove any other components?

Hi, transfer RC823 to RC812 and RC822 to RC805 that's it.

Nope, it didn't work. I'll try couple times this config on this board, bios still read onboard ram. Maybe someone have other config to share ?

Also had no success wits this board, 4Gb Micron RAM located. Desolder it, reball and got it working. One hour of haemorrhoid
