4 GB DDR2 SODIMM for Toshiba Satellite

This 4 GB DDR2 800 MHz SODIMM module is built for Toshiba Satellite A505 models including the 6960, 6965, 6966, 6967, 6969, 6980, 6983 and 6984. It suits owners of those laptops who need a direct replacement or a single-slot upgrade.

Single stick with guaranteed fit

The kit contains one 200-pin unbuffered non-ECC stick rated at PC2-6400 with CL6 timing. Computer Memory Solutions tests each unit against the listed Satellite models so the module installs without configuration changes.

DDR2 platform ceiling

The Socket 505 platform accepts a maximum of 8 GB across two slots. If a 4 GB stick is installed the system may recognise only 3.5 GB or less depending on memory allocation. DDR2 voltage is fixed at 1.8 V and the interface does not support higher speeds or later memory generations.

Questions about this item

Will the 200-pin DDR2 SODIMM slot or the 1.8V voltage requirement ever need servicing?

The 200-pin DDR2 SODIMM slot and 1.8V voltage are fixed hardware specifications; they do not require maintenance or replacement during the module's service life.

What limit appears first when running the CL6 6-6-6 timing continuously?

The CL6 6-6-6 timing operates within the DDR2 800 PC2 6400 specification; the first limit under sustained use is the platform's maximum memory capacity of 8GB across two sockets.

How much heat does the unbuffered non-ECC module produce at 1.8V during all-day operation?

The unbuffered non-ECC module runs at the standard DDR2 1.8V without a heat spreader; typical DDR2 SODIMM power draw at this voltage is low enough that passive laptop cooling handles all-day operation.
