2GB DDR2 800MHz SODIMM module

This Computer Memory Solutions CM256646400SO is a 2GB DDR2 800MHz SODIMM built for specific Toshiba Satellite laptops. It arrives new as a single 200-pin unbuffered stick rated at 1.8V with CL6 timing. The kit contains one module ready for a straightforward memory upgrade.

Suits owners of listed Satellite models needing

This module suits owners of the compatible Toshiba Satellite L355 models who have a free SODIMM slot and want to add 2GB of memory. It is not for systems that require ECC or registered memory. Buyers needing more than 4GB total system memory or those whose laptops use a different pin count or voltage should look at something else.

DDR2 800 (PC2-6400) 200-pin SODIMM specification

The decisive specification is the DDR2 800 (PC2-6400) 200-pin SODIMM interface. Only laptops that accept this exact DDR2 generation, pin layout and voltage will recognise the module. Check the system manual to confirm the slot type and maximum supported capacity before purchase.

Questions about this item

Does the 1.8 V DDR2 module run hot or draw much power in a Satellite L355-S7905 used all day?

DDR2 at 1.8 V is a low-voltage design; the unbuffered SODIMM has no heat spreader and draws minimal power during continuous operation.

What must the laptop already have for this 200-pin SODIMM to work?

The Toshiba Satellite must provide a free DDR2 SO-DIMM slot and a chipset that supports PC2-6400 800 MHz memory.

Will this CL6 2 GB stick work alongside an older 1 GB DDR2 module in the second socket?

Yes, the system accepts two SODIMMs up to 4 GB total; mixing capacities is supported though both run at the slower module's speed.
