8GB DDR2 DIMM kit for desktop upgrades

This kit provides eight gigabytes of DDR2 memory in four 2GB modules. It suits owners of older desktop systems that use 240-pin DIMM slots and require PC2-6300 or PC2-6400 speeds. The unbuffered, non-ECC design matches standard consumer motherboards from the DDR2 era.

Straightforward 240-pin installation

Each module keys into a standard 240-pin DDR2 slot at 1.8 volts. Problems usually arise when mixing these sticks with modules of different voltages, speeds or ranks, which can prevent the system from posting. Installing all four identical modules together avoids timing mismatches.

PC2-6300/PC2-6400 speed rating decides fit

The kit is rated for 800 MHz operation under both PC2-6300 and PC2-6400 specifications. If the motherboard only supports lower DDR2 speeds, the memory will not run at its rated frequency. Buyers needing ECC, registered or lower-voltage DDR2 should choose a different product.

Questions about this item

How can I confirm the DDR2 kit is running at 800MHz after installation?

Enter the BIOS or use a tool such as CPU-Z and verify the memory frequency reads 800MHz with PC2-6400 or PC2-6300 timings shown.

What exactly ships in the box and is anything else required to use the 8GB DDR2 kit?

The package contains four 2GB DDR2 DIMMs; no extra cables, brackets or software are needed — just open DIMM slots on a desktop motherboard.

The listing shows PC2-6300 and PC2-6400 — which one should I pick for my system?

Both ratings refer to the same 800MHz modules; the kit will operate at whichever speed your motherboard supports, so no separate version choice is required.
