System-specific DDR2 upgrade for Emachines 250

This 2GB DDR2 667MHz SODIMM is built to match the Emachines 250 Netbook series. It installs in a 200-pin slot and runs at 1.8V with CL5 timing. The single module uses major-brand chips and requires no configuration.

Buyers with an Emachines 250 needing one 2GB stick

The kit contains exactly one 2GB module, so systems that already have two populated slots cannot use it without removing existing memory. Buyers who need ECC, registered memory or a different pin count should look elsewhere.

200-pin DDR2 SO-DIMM at 667MHz

The module follows the PC2 5300 standard with 5-5-5 timings and operates at 1.8V. It is unbuffered, non-ECC and organised as 2Rx8. This pin count and voltage are the deciding factors for compatibility with the Emachines 250 series.

Questions about this item

Does my eMachines 250 netbook need an empty 200-pin SODIMM slot to accept this 2GB DDR2 667 module?

Yes, the module fits a 200-pin DDR2 SO-DIMM socket and each slot supports up to 2GB, so one free slot is required.

Will this CL5 1.8V DDR2 stick run stably if the other slot still has the original factory memory?

The module is unbuffered non-ECC DDR2 667 at 1.8V with CL5 timing; the system will clock both sticks to the slowest common speed and voltage.

How can I confirm the new stick is recognised at 2GB and 667 MHz after installation?

Check the BIOS memory summary or Windows Task Manager — it should show 2GB total for this module running at 667 MHz (PC2-5300).
