Sony Vaio Z40UL MB Faulty onboard RAM
Hello to all.
I have a Z40UL mobo (MBX-278) with faulty onboard RAM (4Gb)
I can't find the schematic to see if it's possible to disable onboard ram.
What happens if I just remove all the onboard ram chips and install a memory module on the empty slot?.
Machine boots fine but gives blue screens.
Memtest86 confirmed the faulty ram
Any advise would be great
