Compatible eMachines W3621 W3622 W3623 W3626 W3629

This 1GB DDR2 667 module is built for the listed eMachines desktops. It uses a 240-pin DIMM form factor and runs at PC2 5300 speed with CL5 timing. The kit contains a single unbuffered non-ECC stick.

240-pin DDR2 DIMM with 1.8V operation

The module fits standard DDR2 slots on the compatible boards and draws 1.8V. Major brand chips are used without a heat spreader. The 2Rx8 rank organisation matches the original specification for these systems.

Single stick upgrade in a 1 piece kit

One memory stick is supplied so you can populate one of the two available sockets. The system maximum is 2GB so adding a second identical module completes the upgrade. Buyers who want more storage or a different memory generation cannot use this part.

Questions about this item

Does the PC2 5300 DDR2 667 standard limit the bandwidth on my Emachines W3621?

The module runs at DDR2 667 with a PC2 5300 rating, so the peak transfer rate is capped at the 5300 MT/s specification of that standard.

Will the 240-pin DIMM fit the two memory slots on an Emachines W3626?

Yes, it is a 240-pin unbuffered non-ECC DIMM, which matches the physical slot keying and electrical requirements of those systems.

What is the correct way to seat the stick so the motherboard recognises the full 1 GB?

Align the notch with the slot key, press down evenly until both side clips click shut, then power on; the BIOS will detect the 1 GB automatically.
