Capacity and form factor

This 4 GB SODIMM module uses the 200-pin DDR2 layout and runs at 800 MHz with a CAS latency of 6. It is built for laptops or compact desktops that accept DDR2 SO-DIMM memory and need a single 4 GB stick.

DDR2 speed ceiling

The DDR2 interface tops out at 800 MHz on this module, so the memory bus cannot exceed the PC2-6400 bandwidth rating. Any system limited to slower DDR2 grades will clock the stick down to its own maximum frequency.

Upgrade context

It replaces a lower-capacity or slower DDR2 SODIMM in machines that support 4 GB modules and a 64-bit operating system. The jump is worthwhile when the board and CPU can address the full 4 GB and the existing memory is a bottleneck.

Questions about this item

Should I choose a single 4 GB module or add a second one for dual-channel?

The kit contains one 4 GB SODIMM. Installing a second identical module enables dual-channel operation on platforms that support it, doubling memory bandwidth.

What does the 800 MHz rating deliver in everyday use?

At 800 MHz with CL6 timing, the module transfers data at the PC2-6400 rate, keeping older DDR2 notebooks responsive for office tasks and light multitasking.

Will the 200-pin DDR2 interface fit my laptop and what speed ceiling does it impose?

The 200-pin SODIMM fits DDR2 laptop slots only; the memory controller will run at 800 MHz maximum, so faster DDR2 modules would downclock to this speed.
