Four green DDR2 memory sticks with gold contacts

SK hynix

SK hynix 8GB DDR2 Desktop RAM 4 x 2GB PC2-6400 800MHz

SKU CH-9KJ3-YP7GF

Four 2 GB DDR2 modules running at 800 MHz give 8 GB total capacity for older desktop systems

  • Total capacity8 GB (4 × 2 GB)
  • 8GB total capacity from four 2GB modules
  • DDR2 800MHz data rate for responsive desktop performance
  • PC2-6400 bus type matches compatible motherboards
  • 240-pin DDR2 SDRAM form factor fits standard slots
  • Non-ECC unbuffered design with CL6 latency at 1.8V

8GB DDR2 Kit for Legacy Desktops

This kit supplies 8 GB of DDR2 memory in four 2 GB modules built to the PC2-6400 standard at 800 MHz. It is intended for older desktop platforms that accept 240-pin unbuffered non-ECC DIMMs and need a full four-slot population.

Straightforward DIMM Installation

Each module uses the standard 240-pin DDR2 keying so it seats in any compatible desktop slot without tools or cables. The main risk is mixing these 1.8 V sticks with memory that requires a different voltage or ECC function, which can prevent the system from posting.

Four-Slot Capacity with 800 MHz Headroom

The 8 GB total gives ample space for period-correct operating systems and typical office or light multimedia workloads. Bandwidth tops out at the PC2-6400 rating, so memory-intensive tasks such as modern virtualization or large dataset processing will exhaust throughput before capacity becomes the limit.
