2GB DDR2 800 SODIMM for legacy laptops

This 2GB SODIMM module uses DDR2 technology at 800MHz with a CAS latency of 6. It fits 200-pin slots and operates at 1.8V without ECC or registered buffering. The 2Rx8 rank configuration is built with major brand chipsets for broad compatibility.

Suits older notebooks needing a single 2GB stick

This module is intended for systems that specifically accept DDR2 SODIMM memory. It is not for users who need ECC error correction or registered signal buffering. Buyers with platforms requiring a different memory generation, higher capacities per slot, or matched-pair kits for dual-channel operation should look elsewhere.

200-pin DDR2 SODIMM form factor decides fit

The 200-pin SODIMM interface is the single specification that determines whether this module installs in a given machine. Verify the laptop or motherboard manual calls for 200-pin DDR2 SO-DIMMs before purchase. The part number CM256646400SO identifies this exact 2GB 800MHz CL6 configuration.

Questions about this item

Will this DDR2 800MHz 2Rx8 SODIMM run correctly if I keep my existing slower DDR2 modules installed?

Yes, the system will run all memory at the speed of the slowest installed module or the processor limit, so mixing is possible but overall performance drops to that lower rate.

How can I confirm the module is running at its rated 800MHz CL6 1.8V after installation?

Check the memory tab in CPU-Z or your BIOS/UEFI memory information screen; it should show DDR2-800 (PC2-6400), CAS latency 6-6-6, 1.8 V, and single-channel 64-bit width.

Does the box contain only the 2GB SODIMM or are any tools or adapters included for a 200-pin slot?

The package includes one 2GB 200-pin SODIMM only; no tools, adapters, or additional cables are supplied.
