In my case, I recorded the SPI memory, the error persists = Fail

change for:
ID2=0; RC1612=OK
ID3=0;RC1610 = OK
ID4=1; RC1608=FAIL (move RC1607 to RC1608)
ID5=0 ; RC123=FAIL (move RC1606 to RC123)

Hi, friend.I need your help, this laptop has damaged on-board memory.
In addition to the integrated memory, it has a free slot for a memory dimm.

I want to disable the memory by modifying the bios.
You can help me?
