SKU CH-K8WQ-S80F5

A single 1 GB DDR2 desktop memory module running at 533 MHz with a 240-pin DIMM interface

  • Capacity1GB
  • Adds 1 GB of system memory for smoother multitasking
  • Runs at 533 MHz DDR2 speed for responsive performance
  • PC2-4200 rating matches legacy motherboard specifications
  • 240-pin DIMM fits standard desktop memory slots
  • Single module design allows flexible upgrade configurations

Capacity and use

This Kingston DDR2 module adds 1GB of memory to a desktop that uses 240-pin DIMM slots. It is suited for older systems needing a single stick to reach a required total capacity.

Practical limits of DDR2 533

The module runs at 533 MHz with a PC2-4200 rating, so bandwidth is capped at that speed. Mixing it with faster DDR2 will force the system to operate at 533 MHz, and dual-channel benefit is not available with a single stick.

Compatibility checks

Verify that the motherboard accepts 240-pin DDR2 DIMMs and supports 533 MHz operation. Confirm an empty slot is available and that the board does not require memory in matched pairs.

Questions about this item

Should I pick the 1GB DDR2 533MHz module or look for a different capacity?

This module provides exactly 1GB of DDR2 memory; choose it if your system needs a single 1GB stick at 533MHz, otherwise select the capacity your motherboard requires.

What does the 533MHz rating mean once the stick is installed?

The memory will run at up to 533MHz, delivering a peak transfer rate of 4200 MB/s when the motherboard supports that speed.

Is the 240-pin DDR2 interface compatible with my board and what speed does it cap at?

The 240-pin DDR2 DIMM fits standard DDR2 desktop slots and is rated for 533MHz (PC2-4200); actual speed is limited by the motherboard's memory controller.
