Acer Aspire DDR2 667 kit

This 2 GB kit contains two 1 GB unbuffered DIMMs built to the DDR2 667 standard. It is designed for owners of Acer Aspire E600, E650, E700 and E571 desktops who need to restore or expand system memory.

Matched pair for dual-channel

The two modules share identical 5-5-5 timings and 1.8 V operation so the memory controller can run them in dual-channel mode without manual configuration. No heat spreaders are fitted, keeping the profile low for tight chassis clearance.

Simple 240-pin installation

Each stick inserts into a standard 240-pin DDR2 slot; the keyed notch prevents backward insertion. The only common issue is mixing these non-ECC modules with registered or ECC memory already present, which will prevent the system from posting.

Questions sur cet article

Will the 240-pin DDR2 modules need any cleaning or contact maintenance over time?

No routine cleaning is required; the gold-edge contacts are designed for the life of the module, and the unbuffered, non-ECC design has no moving parts to service.

What limits sustained throughput on these PC2-5300 667 MHz sticks?

The 667 MHz clock and CL5 5-5-5 timings set the maximum bandwidth; the memory controller in the Acer Aspire E600, E650, E700 or E571 will not push data faster than the DDR2-5300 rating.

How much heat and power do the two 1 GB DIMMs draw when the system runs all day?

Each module operates at 1.8 V without a heat spreader, so total power stays low and the sticks run cool enough for the standard chassis airflow in the compatible Acer desktops.
