Capacity and Compatibility

This 2GB DDR2 SO-DIMM module is built for specific Asus Eee PC netbooks including the 702, 900, 900A, 900 XP and 1201T models. It uses a 200-pin form factor and runs at 800 MHz with CL6 latency. The unbuffered, non-ECC design matches the original memory specification for these systems.

Bus Speed Limitation

Although the module is rated for 800 MHz operation, the Intel Atom processor in these netbooks runs the memory bus at up to 667 MHz. The stick will downclock automatically to match the processor limit. A BIOS update is required after installation so the system recognises the full 2048MB capacity.

Upgrade Scope

This single module fills the only memory socket in the supported Eee PC models, raising total system memory to the 2GB maximum. It replaces the factory-installed module rather than adding to it. The upgrade is worthwhile when the original capacity restricts multitasking or prevents modern browser versions from running smoothly.

Questions about this item

Should I choose the 2 GB DDR2 800 module or a different capacity for my Asus Eee PC 1201T?

The Asus Eee PC 1201T supports a maximum of 2 GB in one socket, so this single 2 GB stick fills the slot completely.

My Atom processor only runs the memory bus at 667 MHz — will the 800 MHz rating still help?

The module will run at the processor's 667 MHz limit, but the CL6 timing at that lower speed can still feel snappier than a slower-rated stick.

Does the 200-pin DDR2 SO-DIMM interface cap the bandwidth on my netbook?

The 200-pin DDR2 SO-DIMM interface is the physical and electrical limit for these systems; the Atom's 667 MHz bus is the practical ceiling.
