2 GB DDR2 SO-DIMM for eMachines netbooks

This 2 GB DDR2-667 module uses a 200-pin SO-DIMM form factor and runs at 1.8 V with CL5 timing. It is built as a single unbuffered non-ECC stick ranked 2Rx8 and carries major-brand chips. The kit contains one memory module intended for specific eMachines netbook models.

Suits owners of listed eMachines netbooks

The module is validated for eMachines Em250, Em350, Emd727 and Eme625 series netbooks including sub-models 5192, 5305, 5522 and 5712. Each socket accepts up to 2 GB and the system maximum is 4 GB across two sockets. Buyers whose laptops use a different pin layout or voltage cannot use this module.

DDR2-667 (PC2-5300) speed rating

The memory operates at 667 MHz with a PC2-5300 data rate and 5-5-5 timings. This speed grade determines whether the part matches the netbook's memory controller requirements. Verify the system documentation calls for DDR2-667 before purchasing.

Questions about this item

Will this 200-pin DDR2 SO-DIMM fit the memory slot in my eMachines eM250 netbook?

Yes, the 200-pin DDR2 SO-DIMM form factor matches the slot used in the eMachines eM250, eM350, eMD727 and eME625 series netbooks listed for this module.

What is the correct way to seat this SO-DIMM so the laptop recognises the full 2 GB?

Insert the module at roughly a 30-degree angle until the gold edge disappears, then press down firmly until both side clips click; the step most people miss is pressing hard enough to engage both clips.

If a memory chip fails years from now, what replacement options exist for this CM256645300SO stick?

Computer Memory Solutions provides a limited lifetime warranty when purchased directly from them, so a verified failure would be handled through their warranty process.
