  • Capacity2GB
  • Type200-Pin DDR2 SO-DIMM
  • SpeedDDR2 667 (PC2 5300)
  • CAS LatencyCL5
  • Timing5-5-5
  • Voltage1.8V
  • 2GB capacity expands Eee PC memory to the 2GB maximum
  • 667MHz DDR2 speed matches the Atom processor bus limit
  • CL5 5-5-5 timing delivers responsive access for netbook workloads
  • 8V unbuffered SO-DIMM installs directly into the 200-pin slot
  • Tested compatible with Asus Eee PC S101, T101Mt, X101, T91 and related models

Direct-fit upgrade for select Asus Eee PC netbooks

This 2 GB DDR2 SO-DIMM is built to the exact 200-pin, 1.8 V, CL5 specification required by the listed Eee PC models. It installs in the single memory socket and is verified for the S101, T101Mt, X101 and T91 families.

Not for systems that need more than 2 GB total

The platform supports a maximum of 2 GB and provides only one SO-DIMM socket, so this module cannot be paired with another stick. Buyers whose laptop accepts higher capacities or dual-channel configurations should look for a different part.

Runs at 667 MHz (PC2-5300) with CL5 5-5-5 timings

The Intel Atom memory controller limits the bus to 667 MHz even if faster modules are fitted, so this speed grade matches the hardware ceiling. The stick is unbuffered, non-ECC and uses major-brand chips in a 2Rx8 organisation.

Questions about this item

How do I install this 200-pin DDR2 SO-DIMM into my Asus Eee PC and what BIOS step must I follow?

Insert the module into the single SODIMM socket, then power on and press F2 to enter BIOS; verify Installed Size shows 2048 MB, save and exit so the system recognises the full 2 GB.

Will this CM256645300SO module need any firmware updates or component replacements during its service life?

No firmware updates are required for the memory itself; the only related action is a one-time BIOS update after installation to ensure the 2048 MB capacity is reported correctly.

What speed ceiling will I hit first when running this DDR2-5300 stick continuously in an Atom-based Eee PC?

The Intel Atom processor limits the memory bus to 667 MHz, so sustained workloads cannot exceed that frequency even though the module is rated for DDR2-5300.
