For Toshiba S1800-100, if i insert my default 12MB PC100 SD-RAM memory
to SLOT 1, i can't see anything in CPU-Z's(recognition software-famous)
SPD tab. Only "Toshiba Unique" and 128MB appears.

But if i insert the memory to SLOT 2, i can see everything like CAS-RAS
timings, part number, manufacturer and etc... in "SPD" tab. Why are
these 2 slots behave different for reading SPD chips?

Why can't i read SPD info if i insert memory to Slot 1?

Similiar link to this issue:

Note: Everest Home Edition is cannot read SPD info even my memory is in
Slot 1 or 2.

Thank you.
