Questions about this item

Will the 200-pin SO-DIMM slot need replacement later?

The 200-pin SO-DIMM is a fixed laptop slot; it does not wear out and only needs attention if physically damaged.

What limit appears first when running the 266 MHz PC2100 module continuously?

Sustained use is limited by the 266 MHz bus speed and PC2100 bandwidth ceiling.
