Hynix 4GB DDR2 800 PC2-6400 CL6 240-pin desktop RAM

SKU CH-S0T4-ZZ3AJ

4 GB DDR2 desktop module running at 800 MHz with CL6 latency and 1.8 V operation

  • Total capacity4 GB
  • Rated speedDDR2 800 (PC2 6400)
  • 4 GB capacity extends multitasking headroom on DDR2 systems
  • 800 MHz DDR2 speed matches PC2-6400 bandwidth for responsive legacy performance
  • CL6 latency keeps timing tight for stable desktop operation
  • 8 V non-ECC unbuffered design fits standard 240-pin DDR2 slots

4GB DDR2 800 desktop module

This Hynix DIMM delivers 4GB of DDR2 memory at 800 MHz with a CL6 latency rating. It is built for older desktop platforms that require 240-pin unbuffered non-ECC modules running at 1.8 V. The single stick suits upgrades or repairs on legacy systems limited to the PC2-6400 standard.

Single stick simplifies legacy upgrades

The package contains one 4GB module so buyers can add capacity without purchasing matched pairs. Non-ECC unbuffered operation means it fits standard consumer boards that do not support registered or error-correcting memory. This keeps installation straightforward for machines still running on the DDR2 platform.

Questions about this item

Will the 240-pin DDR2 module need any maintenance or replacement later?

No routine maintenance is required for the DDR2 DIMM; it is a solid-state component with no moving parts and should last the life of the system unless physically damaged.

What limit appears first during sustained use of this 800 MHz DDR2 memory?

The 1.8 V operating voltage and CL6 latency define the thermal and timing envelope; sustained heavy workloads will hit the DDR2 speed ceiling before other bottlenecks emerge.
