200-Pin DDR2 SO-DIMM for HP Notebooks

This 64MB DDR2 667 module is built for HP and Compaq business notebooks such as the 6715S, 6720S, 6735S, 6820S, 6910P and 8510P. It uses a 200-pin SO-DIMM form factor and runs at 1.8V with CL5 timing. The unbuffered, non-ECC stick is a direct replacement for original memory in those systems.

Suits owners of listed HP models.

The part is validated only for the notebooks named in the compatibility list. Buyers with different HP series or other brands cannot use this module. Systems that require registered or ECC memory are also unsupported. Anyone needing a higher capacity than 64MB must look elsewhere.

64MB capacity decides fit

The single specification that determines suitability is the 64MB density. If the target notebook accepts this capacity in a 200-pin DDR2 SO-DIMM slot, the module will work. If the machine requires a larger or smaller density, this stick is not the correct part.
