A-Tech 2GB DDR2 1066MHz PC2-8500 1.8V CL7 240-Pin Desktop RAM

Desktop DDR2 Upgrade Module

This A-Tech module is a 2 GB DDR2 DIMM rated for 1066 MHz operation at 1.8 V. It targets owners of older desktop systems that require PC2-8500 unbuffered non-ECC memory. The 240-pin form factor fits standard DDR2 slots on compatible motherboards. Installation is a straightforward press-in upgrade for supported platforms.

Capacity and Headroom

The single 2 GB stick adds modest capacity for everyday tasks such as web browsing, office applications and light multitasking. Systems limited to 4 GB or 8 GB maximum will benefit from the extra headroom this module provides. Performance scales with the 1066 MHz data rate, though bandwidth remains constrained by the DDR2 architecture. Workloads exceeding available memory will still trigger paging to storage.

PC2-8500 Speed Rating

The decisive specification is the PC2-8500 rating, which confirms a 1066 MHz tested frequency and CL7 latency at 1.80 V. Motherboards that only support lower DDR2 speeds will downclock the module automatically. Buyers must verify that their system accepts DDR2 1066 unbuffered DIMMs before ordering. No other memory type or voltage is compatible with this part.
