2GB DDR2 SO-DIMM for Asus Eee PC 1001Px

This 2GB DDR2 667MHz SO-DIMM module is built for the Asus Eee PC 1001Px and compatible Seashell series netbooks. It uses a 200-pin unbuffered non-ECC design with CL5 5-5-5 timings at 1.8V. The kit contains one stick to fill the single memory slot in these systems.

Upgrading the single slot on Atom N450 netbooks

Owners of an Asus Eee PC 1001P, 1001Px, 1002HA or 1002HAG with an Atom N450 processor can use this module to reach the 2GB maximum. Buyers who need more than 2GB of memory or who are repairing a different laptop platform should look elsewhere because this module is validated only for the listed models.

DDR2 667MHz speed matched to the Atom front-side bus

The Intel Atom N450 runs the memory bus at 667MHz so this PC2 5300 module operates at the processor's native limit. Faster DDR2 modules will downclock to this speed and offer no advantage in these netbooks.

Questions about this item

What comes in the box and do I need anything else to install this CMS CM256645300SO module in my Eee PC 1001Px?

The package contains one 2GB DDR2 667MHz SO-DIMM stick. No extra parts or tools are required; the module fits directly into the single 200-pin memory socket of the Eee PC 1001Px.

Should I choose this 2GB PC2-5300 CL5 kit or a different capacity for my Asus Eee PC 1001Px?

The system maximum is 2GB and there is only one memory socket, so this single 2GB module is the only upgrade that reaches the full supported capacity.

The headline says 667MHz, but the Atom N450 runs the bus at 667MHz — will I actually see 2048MB in Windows?

Yes, after installing the module you must enter BIOS (press F2 on boot) and verify Installed Size shows 2048MB; saving the BIOS update lets the OS recognise the full 2GB.
