Compatible 2GB DDR3 SO-DIMM upgrade

This 2GB DDR3-1066 module is built for the Acer Aspire One D255E series, including the AOD255E-13421 and D255E-13421 models. It uses a 204-pin SO-DIMM form factor and runs at 1.5V with CL7 7-7-7 timing. The kit contains one unbuffered, non-ECC stick.

Suits single-slot netbooks at the 2GB limit

Owners of the listed Acer Aspire One models can fill the sole memory socket with this 2GB stick to reach the system maximum. Buyers needing more than 2GB of total memory cannot use this part because the platform caps at 2GB. Systems that require ECC or registered modules are also not supported.

Single SO-DIMM socket caps total memory at 2GB

The Acer Aspire One D255E provides one expansion socket and a 2GB maximum, so this 2GB module occupies the only slot and saturates the platform limit. No additional memory can be added after installation.

Questions about this item

Will the CL7 latency at 1066 MHz bottleneck sustained workloads?

The module runs at DDR3-1066 with CL7 7-7-7 timings and 1.5 V, so latency is fixed by the JEDEC rating for this speed grade.

Does the stick run hot or draw extra power during all-day use?

Rated at 1.5 V with no heat spreader, it operates within standard DDR3 SO-DIMM power limits for continuous operation.

Must the Acer Aspire One D255E have a free 204-pin DDR3 slot to install this?

Yes, the laptop provides one 204-pin DDR3 SO-DIMM socket and supports a maximum of 2 GB.
