A-Tech 1GB DDR2 800MHz Desktop Module

This A-Tech module is a 1GB unbuffered DIMM built to the DDR2 800 standard (PC2-6400). It runs at the standard 1.8V voltage with CL6 latency and uses the 240-pin form factor for desktop motherboards. The kit contains a single stick tested at 800 MHz and carries no ECC or registered buffering.

Suits legacy DDR2 desktops.

The module targets older AMD and Intel desktop platforms that accept non-ECC DDR2 memory at 1.8V. Builders repairing or upgrading such systems can install it directly. Systems that require ECC, registered modules, or a different voltage cannot use this part.

The deciding spec is DDR2 800 at 1.8V on a 240-pin

Before buying, confirm the motherboard supports DDR2 800 (PC2-6400) unbuffered memory at 1.8V with 240-pin slots. If the board calls for a different DDR generation, ECC, registered DIMMs, or another voltage, this module will not fit or function.

Questions about this item

How do I install the 240-pin DDR2 DIMM and which orientation step is most often missed?

Align the notch on the module with the key in the slot, press straight down until both side clips click locked, and verify the clips have fully engaged on each end.

What maintenance or replacement will this 1.8V DDR2 module need over time?

No scheduled maintenance is required; if errors appear, reseat the module or test with a memory diagnostic before considering replacement.

At what speed ceiling does this PC2-6400 CL6 kit hit its limit during sustained workloads?

The module is rated for 800 MHz operation; sustained loads will not exceed that validated frequency.
