Speed DDR2 533 (PC2 4200)

  • 2GB dual-channel kit expands desktop memory capacity
  • 533MHz DDR2 speed matches PC2-4200 system requirements
  • 8V standard voltage ensures broad motherboard compatibility
  • 240-pin unbuffered DIMM form factor fits DDR2 desktop slots
  • Rigorously tested modules deliver reliable non-ECC performance

Kit Configuration

This A-Tech kit provides two gigabytes of desktop memory as a matched pair of one-gigabyte modules. The sticks are unbuffered non-ECC DIMMs that run at the standard 1.8 volts for DDR2 platforms. They are designed for straightforward installation in compatible desktop computers.

Intended Use

The dual-channel kit suits owners of older desktops that accept DDR2 533MHz memory and want a simple capacity increase for everyday tasks. Systems requiring error-correcting code, registered modules, or a different DDR generation will not be compatible with this kit.

Deciding Specification

The modules operate at a tested frequency of 533 megahertz, corresponding to the PC2-4200 designation. This speed rating is the single figure that determines whether the memory matches the motherboard's supported specification.

Questions about this item

What speed limit will I hit first when the A-Tech DDR2 533 modules run sustained workloads?

The tested frequency is 533 MHz, so the memory bus will top out at that rate before any other component becomes the bottleneck.

How much heat or power should I expect from the kit once it runs all day?

Each DIMM operates at the standard 1.8 V DDR2 voltage, so power draw and heat output stay at typical DDR2 levels for continuous operation.

What must my desktop already have for this 240-pin kit to work?

A motherboard with DDR2 DIMM slots that accept 1.8 V unbuffered non-ECC modules and can run at PC2-4200 speeds.
