Matches Acer Aspire One D260 and D257

This 2GB DDR3 SO-DIMM is built for the Acer Aspire One D260 and D257 netbooks. It installs in the single 204-pin slot to restore or expand system memory. The module runs at 1066 MHz with CL7 latency and 1.5V power.

Suits owners keeping a legacy netbook running

Buyers who need more than 2GB of memory should look elsewhere, as the platform and this module cap capacity at this level. The stick is unbuffered and non-ECC, so it will not work in servers or workstations that require registered or error-correcting memory.

Single 2GB stick at DDR3 1066 CL7

The kit contains one 2GB module rated at PC3-8500 with 7-7-7 timing and 1Rx8 organisation. No heat spreader is fitted, matching the slim chassis of the target netbooks. Computer Memory Solutions backs the part with a limited lifetime warranty.
