1 GB DDR2 desktop DIMM

This Simmtec module adds 1 GB of DDR2 memory to a desktop computer. It is intended for owners of older systems that use 240-pin DIMM slots and want a straightforward capacity increase for everyday tasks.

PC2-6400 CL=6 speed rating

The single specification that determines fit is the PC2-6400 CL=6 rating, which corresponds to DDR2-800 operation at CL6 latency. Your motherboard must support this exact speed grade and timing for the module to run at its rated performance.

Simple slot insertion

Installation consists of aligning the notch on the 240-pin edge connector with the key in the DIMM slot and pressing firmly until the retention clips click. The most common issue is a mismatched speed grade or voltage requirement, which can prevent the system from posting or cause the memory to run at a lower speed.

Questions about this item

What real-world bandwidth does the PC2-6400 rating deliver in a desktop?

The PC2-6400 rating corresponds to a peak transfer rate of 6400 MB/s when the module runs at DDR2-800 speeds.

How does the DDR2 interface and CL=6 latency affect usable performance?

DDR2-800 with CL=6 timing provides a theoretical maximum of 6400 MB/s; actual throughput depends on the motherboard's memory controller and BIOS settings.

Will this 240-pin DIMM fit my desktop motherboard's memory slots?

The module uses the standard 240-pin DDR2 DIMM form factor and requires a desktop board with DDR2 slots keyed for 1.8 V unbuffered non-ECC memory.
