Two green DDR2 desktop memory modules with gold contacts

Patriot Memory

Patriot Memory Signature 4GB (2 x 2GB) DDR2 800 CL6 desktop RAM

SKU CH-21CX-XEA7D

A 4 GB dual-channel kit of DDR2 desktop memory running at 800 MHz with CL6 latency and 1.80 V operation

  • Capacity4GB (2 x 2GB)
  • SpeedDDR2 800 (PC2 6400)
  • CAS LatencyCL6
  • Voltage1.80V
  • ECCNon-ECC
  • Buffered/RegisteredUnbuffered
  • 4GB dual-channel kit expands system memory for smoother multitasking
  • DDR2 800 speed transfers data at 800 MHz for responsive performance
  • CL6 latency reduces command delay for quicker application response
  • 80 V operation lowers power draw and heat output
  • Non-ECC unbuffered design ensures broad desktop compatibility

Kit Capacity and Speed

This 4GB kit contains two 2GB DDR2 modules rated for 800MHz operation at PC2-6400 speed. It is intended for desktop owners who need a straightforward capacity increase on platforms that accept this memory generation.

Platform Compatibility Check

Verify that your motherboard supports DDR2 technology and unbuffered non-ECC modules before ordering. The kit runs at 1.80V with CL6 latency, so the board must be able to supply that voltage and timing combination for stable operation.

Thermals and Power Draw

Standard DDR2 modules operating at 1.80V produce modest heat and require no active cooling in typical chassis airflow. Power consumption stays low during normal desktop workloads, and the unbuffered design adds no extra electrical load to the memory controller.

Questions sur cet article

What comes in the Patriot Signature 4GB DDR2 800 kit and what else is needed?

The box contains two 2GB DDR2 unbuffered non-ECC modules rated at 800MHz CL6 1.80V. A compatible desktop motherboard with DDR2 slots is required separately.

Should I choose this 4GB DDR2 800 CL6 kit or a different capacity for my older system?

Pick this 4GB kit if your board supports DDR2 800 and has two free slots; it provides a matched pair running at PC2-6400 with CL6 timing.

What does the PC2-6400 rating mean once the modules are installed?

It means the memory transfers data at 6400 MB/s at 800MHz with CL6 latency at the standard 1.80V DDR2 voltage.
