Compatible upgrade for Acer Aspire One Happy-2Dqpp

This 2 GB DDR2 SODIMM module is built specifically for the Acer Aspire One Happy Happy-2Dqpp notebook. It uses a 200-pin form factor and runs at 667 MHz with CL5 timings. The unbuffered, non-ECC design matches the original system requirements for a straightforward memory increase.

Steady operation at 1.8 V with major-brand chips

The module operates at a standard 1.8 V and uses major-brand chipsets arranged in a 2Rx8 configuration. Without a heat spreader, it relies on the notebook's existing airflow to maintain stable temperatures during extended use. CAS latency of 5-5-5 ensures consistent access times under sustained workloads.

Simple slot installation with capacity limits

Installation involves inserting the single stick into the sole expansion socket, keyed for 200-pin DDR2 SO-DIMMs. The system accepts a maximum of 1 GB with Windows 7 Starter or 2 GB with other operating systems, so exceeding that limit will not yield usable memory. No heat spreader means the module fits tight chassis clearances.

Questions about this item

How much power does the 1.8 V DDR2 module draw when the Acer Aspire One runs continuously?

The module operates at 1.8 V with no heat spreader, so power draw stays low and matches the notebook's original memory specification.

What must the Acer Aspire One Happy-2Dqpp already have for this 200-pin SODIMM to install?

One free 200-pin DDR2 SO-DIMM socket; the system ships with a single slot, so the existing stick must be removed first.

Will this CL5 667 MHz stick work alongside the original PC2-5300 memory already in the netbook?

Yes, it matches the same 667 MHz speed, CL5 timing and 1.8 V voltage, so the system will run both modules at the shared JEDEC profile.
