DDR2 1066MHz dual-channel kit

This A-Tech kit provides 4GB of DDR2 desktop memory in two matched 2GB modules. It is built for systems that accept 240-pin DIMMs running at PC2-8500 speed. The modules are unbuffered and non-ECC, making them suitable for standard desktop motherboards. Compatibility spans a wide range of AMD and Intel platforms that support DDR2 1066MHz.

Standard voltage and tested frequency

Each module operates at the DDR2 standard voltage of 1.8V and has been tested at 1066MHz. The dual-channel configuration allows the memory controller to access both modules simultaneously for improved bandwidth. Quality assurance testing is performed on every module to verify reliable operation under normal desktop workloads. The kit is designed for straightforward installation in compatible desktop computers.

1066MHz tested frequency

The single specification that determines fit is the tested frequency of 1066MHz, labelled PC2-8500. Your motherboard and processor must support DDR2 at this exact speed for the kit to run at its rated performance. If the platform only supports lower DDR2 speeds, the modules will typically downclock automatically. Always verify the supported memory specification of your system before purchase.

Questions about this item

Does this kit require a motherboard with DDR2 1066 support?

The modules are tested at 1066 MHz and will run at the highest speed the motherboard allows, so they will operate in DDR2 1066 slots and downshift if the board only supports lower DDR2 speeds.

What voltage do these modules use and is it standard for DDR2?

They run at 1.8 V, which is the standard DDR2 voltage, so no special voltage settings are needed.

Are the modules ECC or registered?

They are non‑ECC unbuffered DIMMs, the typical type for desktop PCs.
