2GB DDR3 1066MHz SODIMM for eMachines

This 2GB DDR3 SODIMM module is built for specific eMachines notebooks including the E442, E527, E528, E640, E642, D440, D528, D640 and D730. It suits owners of those models who need a direct memory replacement or a simple capacity increase. Buyers with laptops outside this compatibility list should look elsewhere.

PC3-8500 CL7 204-pin specification

The decisive specification is the PC3-8500 1066MHz rating with CL7 7-7-7 timings at 1.5V on a 204-pin unbuffered non-ECC stick. Only systems that accept this exact DDR3 SO-DIMM profile will POST correctly; faster or slower modules, different voltages or registered DIMMs will not work.

Single-stick upgrade for listed notebooks

The kit contains one 2GB stick using 256x8 major-brand chips in a 1Rx8 configuration without a heat spreader. It occupies a single SO-DIMM slot, leaving any second slot free for additional memory if the notebook supports it. Systems requiring ECC, registered memory or a different DDR generation cannot use this module.

Questions about this item

What does the PC3-8500 1066 MHz rating mean once the module is installed in my eMachines notebook?

The module runs at 1066 MHz with CL7 timing, delivering the standard DDR3-8500 bandwidth your chipset expects, so the system recognises the full 2 GB capacity without down-clocking.

Is the 204-pin SODIMM interface the only fitment requirement for these eMachines models?

Yes, the 204-pin DDR3 SO-DIMM form factor matches the memory slots in the listed E442, E527, E528, E640, E642, D440, D528, D640 and D730 notebooks.

Does the stick need a heat spreader or any extra clearance to fit in the D640 or E642 chassis?

No, the module has no heat spreader and uses the standard low-profile SO-DIMM height, so it fits the factory memory compartment without modification.
