2GB DDR2-800 system memory upgrade

This 240-pin DIMM adds 2GB of DDR2 memory at 800 MHz (PC2-6400) with CL6 timing. It is built for desktop systems that require unbuffered, non-ECC modules operating at 1.8V. The single-module kit suits owners of compatible legacy platforms needing a direct capacity increase.

Fits standard 240-pin DDR2 slots without extra power

The module plugs into any desktop board accepting unbuffered DDR2 DIMMs at 1.8V and runs at the slowest speed among installed memory. It requires a 64-bit operating system to address more than 4GB total system memory. Matched-pair installation is recommended by the manufacturer for optimal dual-channel throughput.

Replaces slower or smaller DDR2 modules in older

Swapping out lower-capacity or lower-frequency DDR2 sticks raises the memory ceiling for multitasking on period-correct hardware. The jump is worthwhile when the platform supports 800 MHz operation and the user needs more than the existing amount. It does not serve systems limited to earlier DDR generations or those requiring ECC or registered memory.

Questions about this item

What is the operating voltage of this DDR2 module under sustained load?

The module runs at 1.8 V, the standard voltage for DDR2 memory, and maintains this level during continuous operation.

How much heat or noise does this memory produce when running all day?

As an unbuffered, non-ECC DIMM with no active cooling, it generates minimal heat and makes no audible noise during extended use.

What must my motherboard provide for this 240-pin DIMM to work?

A DDR2-compatible 240-pin DIMM slot supporting 800 MHz (PC2-6400) operation at 1.8 V is required for this module to function.
