Green 240-pin DDR2 DIMM with black memory chips

Computer Memory Solutions

Computer Memory Solutions 4GB DDR2 800MHz 2Rx8 DIMM memory upgrade

SKU CH-WZGF-Z9NSQ

A 4 GB DDR2 800 MHz unbuffered DIMM with 240 pins, CL6 timing and 1.8 V operation for compatible desktop systems

  • Capacity4GB
  • SpeedDDR2 800 (PC2 6400)
  • CAS Latency6
  • Timing6-6-6
  • Voltage1.8V
  • ECCNo
  • 4GB capacity expands system memory for DDR2 platforms
  • 800MHz DDR2-6400 speed matches PC2-6400 specification
  • CL6 6-6-6 timing delivers responsive data access
  • 240-pin unbuffered non-ECC DIMM fits standard desktop slots
  • 8V operation reduces power draw and heat

System-specific DDR2 upgrade

This 4 GB DDR2 DIMM runs at 800 MHz with CL6 timing and 1.8 V unbuffered operation. The 240-pin module uses a 2Rx8 rank layout and major-brand chips. It targets owners of legacy desktops or workstations that require DDR2 memory and need a single 4 GB stick to fill an open slot.

Build integration

The stick fits any standard 240-pin DDR2 slot and runs at the slowest speed of all installed modules or the processor limit. Mixing with existing DDR2 memory is possible but will down-clock the entire array. A 64-bit operating system is required to address more than 4 GB of total system memory.

Kit contents

The package contains one 4 GB module backed by a limited lifetime exchange or repair warranty from Computer Memory Solutions. No additional cables, brackets or software utilities are included. The single-stick kit leaves remaining slots free for future matched-pair upgrades if the platform supports dual-channel operation.

Domande su questo articolo

What is the CAS latency limit that appears first when this DDR2-800 module runs under sustained load?

The module operates at CAS latency 6 with 6-6-6 timings, which is the primary timing constraint under continuous operation.

How much heat and power does this 4 GB DDR2 DIMM produce when running all day at 800 MHz?

It runs at 1.8 V unbuffered without ECC, so power draw and heat stay low for a 240-pin DDR2 module at this speed.

What must the motherboard already provide for this 240-pin DDR2 DIMM to work?

A DDR2 memory slot supporting PC2-6400 at 1.8 V, unbuffered non-ECC operation, and 2Rx8 organisation.
