Two green 240-pin DDR2 desktop memory modules with black chips

Micron Technology, Inc.

Micron Technology, Inc. MT16HTF25664AY-800J1 4GB 2x2GB DDR2 800 CL6 desktop RAM

SKU CH-X05R-1ESTP

A 4GB desktop memory kit with two 2GB DDR2 modules running at 800MHz with CL6 latency

  • Capacity4GB (2 x 2GB)
  • CAS LatencyCL6
  • 4GB total capacity for multitasking headroom with two 2GB modules
  • CL6 latency reduces access delay at 800MHz bus speed
  • PC2-6400U rating matches 800MHz DDR2 bandwidth specification
  • 240-pin DDR2 form factor fits standard desktop DIMM slots
  • Micron-built components deliver consistent reliability for everyday workloads

Memory kit for legacy DDR2 systems

This Micron kit provides four gigabytes of DDR2 memory in a matched pair of two‑gigabyte modules. It is intended for desktop computers that use 240‑pin DDR2 slots and require PC2‑6400U 800 MHz operation with CL6 timing.

Thermals and power in daily use

Standard DDR2 modules run at low voltage and generate modest heat during typical office or web workloads. The memory draws little power, so system fan curves remain quiet and case temperatures stay stable without extra cooling.

Build and connector implications

Each stick uses the 240‑pin DDR2 form factor, so installation is a simple press‑into‑slot action on compatible motherboards. The non‑ECC design suits consumer desktop boards, and the matched pair enables dual‑channel bandwidth where the platform supports it.

Questions about this item

How do I install the 240-pin DDR2 modules and what step is often missed?

Align the notch on each 240-pin stick with the motherboard slot key, press down firmly until both side clips click shut, then verify the BIOS reports 800 MHz operation.

What maintenance or replacement will this DDR2 kit need later?

Dust the gold contacts with compressed air if the system becomes unstable; the modules have no moving parts or batteries, so replacement is only needed if a stick fails.

What limit appears first under sustained load with these CL6 800 MHz modules?

The CAS latency of CL6 at 800 MHz sets the timing ceiling; prolonged heavy workloads will hit this latency bound before bandwidth saturates.
