Targeted Acer netbook upgrade

This 2 GB DDR2 667 MHz SODIMM is built specifically for the Acer Aspire One D250-1958 netbook. It matches the single 200-pin slot and 1.8 V requirement of that platform. Owners of other D250 variants or different brands should verify their exact model number before ordering.

Single-stick simplicity

The package contains one unbuffered, non-ECC module rated PC2-5300 with CL5 5-5-5 timing. No heat spreader is fitted, keeping the profile low for the cramped netbook chassis. The stick simply adds 2 GB of capacity; no drivers, software or configuration utilities are included or required.

Straightforward slot access

Installation involves opening the bottom memory door, releasing the side latches and pressing the module in until it clicks. The only common issue is a BIOS that still reports the original capacity — a restart usually resolves it. Buyers needing more than 2 GB total or a second SODIMM slot cannot use this product.

Questions about this item

Will the DDR2 SODIMM need any replacement or servicing after installation?

The module is unbuffered non-ECC DDR2 with no heat spreader, so it has no moving parts or firmware to service; once seated in the 200-pin slot it runs maintenance-free for the life of the laptop.

What limit appears first when the memory runs continuously at 667 MHz?

The CAS latency of CL5 and 5-5-5 timing set the access-speed ceiling, so sustained workloads hit that latency boundary before any thermal or voltage constraint on the 1.8 V DDR2 chips.

How much heat or fan noise does the 2 GB stick add during all-day use?

With no heat spreader and a low 1.8 V operating voltage, the SODIMM contributes minimal extra warmth, leaving the Aspire One D250-1958's existing cooling unchanged and silent.
