  • Dual-module kit enables dual-channel bandwidth on supported platforms
  • Kingston engineering validated for reliable desktop compatibility

Kingston 4GB DDR2 Kit

This kit provides four gigabytes of DDR2 memory across two matched 2GB modules. It is intended for desktop systems that use 240-pin DIMM slots and run at 800MHz bus speed. The pair suits older office PCs or light home rigs needing a simple capacity boost. ||

Sustained Load Behaviour

Running at PC2-6400 rating, the modules maintain their 800MHz data rate during extended sessions such as long document editing or background backups. Standard JEDEC timings keep latency predictable without voltage increases. Heat output stays modest because the chips operate at stock DDR2 voltage. ||

Compatibility Check

Verify that the motherboard accepts 240-pin DDR2 DIMMs and supports the PC2-6400 speed grade. Confirm the board has at least two free slots and that the BIOS can run memory at 800MHz without manual timing changes. Systems limited to lower DDR2 speeds or proprietary form factors will not work with this kit.

Questions about this item

How much heat and power draw can I expect from these DDR2-800 DIMMs running 24/7?

DDR2-800 modules at standard JEDEC voltage run cool enough for passive airflow in a typical desktop case; no active cooling is required on the memory itself.

What must my motherboard provide for this 240-pin kit to function?

A desktop board with DDR2 slots keyed for 240-pin DIMMs and a chipset that accepts PC2-6400 speeds.

Will these PC2-6400 sticks downclock automatically if paired with slower DDR2 modules already in my system?

Yes, the memory controller will negotiate the lowest common speed so all installed DIMMs run stably together.
