SKU CH-ES31-056HR

8GB dual-channel DDR2 kit running at 533 MHz with PC2-4200 and PC2-4300 ratings, 240-pin DIMMs at 1.8 V for desktop upgrades

  • Capacity8GB (2 x 4GB)
  • 8GB dual-channel capacity for smoother multitasking with 2 x 4GB modules
  • Tested DDR2 reliability at 533MHz PC2-4200/4300 speeds
  • Non-ECC unbuffered design suited for standard desktop workloads
  • 8V operation matching legacy DDR2 platform requirements
  • 240-pin DIMM form factor fits compatible desktop motherboards

Capacity and purpose

This kit provides 8 GB of DDR2 memory in a matched pair of 4 GB modules. It targets owners of legacy desktop systems that still rely on 240-pin DIMM slots and need a reliable upgrade to extend service life.

Interface limits

The modules operate at 533 MHz and are rated for both PC2-4200 and PC2-4300 standards, so the peak bandwidth is capped by the DDR2 generation. Systems that require higher clock speeds or newer memory types will not be able to use this kit.

Build and daily use

Each stick is non-ECC, non-parity and unbuffered, running at the standard 1.8 V. The 240-pin edge connector fits directly into compatible desktop sockets without adapters, and every module is tested before shipment to reduce the risk of crashes or motherboard damage from defective chips.
