8GB DDR2 Kit for Desktop Upgrades

This kit provides eight gigabytes of DDR2 memory in two matched 4GB modules. It is intended for desktop systems that accept 240-pin unbuffered DIMMs running at 667MHz. The PC2-5300 and PC2-5400 ratings cover the same speed grade for broad compatibility.

Straightforward DIMM Installation

Each module slots into a standard 240-pin DDR2 socket and is keyed to prevent incorrect insertion. The 1.8V operating voltage matches the DDR2 specification, so no manual voltage adjustment is required. Problems usually arise when mixing these sticks with modules of different speeds or capacities, which can prevent the system from posting.

Verify Motherboard DDR2 Support

Before ordering, confirm that the motherboard uses DDR2 technology and provides 240-pin DIMM slots. Check the board’s maximum supported memory per slot and total capacity to ensure 4GB modules are accepted. Also verify whether the BIOS requires a specific memory density or rank configuration for stable operation.

Questions about this item

How do I confirm the 667MHz modules are running at the correct speed after installation?

Enter the BIOS or UEFI on first boot and verify the memory frequency reads 667MHz with the voltage set to 1.8V; the POST screen or a utility like CPU-Z will also show DDR2-667 operation.

What exactly ships in the kit and is anything else required to use it?

The package contains two 4GB DDR2 DIMMs (240-pin, non-ECC, unbuffered) for a total of 8GB; no extra cables, brackets or software are needed — just a desktop board with DDR2 slots.

Should I choose the PC2-5300 or PC2-5400 labelled version for my system?

Both ratings refer to the same 667MHz modules in this kit; the memory will run at 667MHz on any board that supports DDR2-5300 or DDR2-5400, so either designation is correct.
