Re: Lenovo Ideapad 330 Onboard Memory Fail

Hi, how can someone identify the particular faulty onboard memory/RAM chip. Definitely going to be just one of the RAM chips and not the entire RAM chips that would be faulty.

THANKS!!! It worked on 320-17IKB Model: 81BJ with board EG521 EG522 EZ511 EG721 NM-B452 Rev-1.0.

Can you share schematic for NM-B452 Rev-1.0?

Stuff RC1631 & 1632 only. Both 10K. This will disable onboard ram and make it sodimm only.

Shift RC1609 to RC1610 if you want to disable graphics.

Thats All.

If the laptop gets flashed again with a different bios it won`t boot.The hardware solution is permanent.

Agree with @smdflea's views. Disabling onboard ram with bios edit is the last option and should be done only on boards where there is no option to disable onboard ram(eg Lenovo NM-D031). Disabling the ram permanently thru Board ID is the best and lasting solution.

If the customer opts for a bios update, you know what will happen with the onboard ram disabled thru bios edit.
