  • Dual-channel 4 GB kit doubles bandwidth for DDR2 800 systems
  • CL6 latency at 1.8 V keeps timing tight on PC2-6400 boards
  • Unbuffered non-ECC UDIMM drops straight into standard desktop sockets
  • Major-brand Samsung, Micron or Hynix ICs deliver proven stability
  • 240-pin DDR2 form factor matches legacy motherboard slots exactly

Kit contents and fit

This kit provides 4 GB of DDR2 memory as two 2 GB modules running at 800 MHz with CL6 latency at 1.8 V. It targets older desktop systems that use 240-pin UDIMM slots and need a simple capacity boost for everyday tasks.

Motherboard checks

Verify that the board accepts DDR2 PC2-6400 unbuffered non-ECC UDIMMs and has two free 240-pin slots. Confirm the BIOS can run the memory at 1.8 V and CL6 timings without manual voltage adjustment. Check the qualified-vendor list for compatibility with Samsung, Micron or Hynix chips.

Sustained load behaviour

Modules are stress tested under load before shipping to confirm stability during extended sessions. The absence of a heat spreader means airflow across the PCB is the only cooling path, so case ventilation should be adequate for continuous operation. Rated voltage and timings remain constant throughout prolonged use.

Questions about this item

Will this kit work in a motherboard that only supports DDR2 800?

Yes, the modules are rated DDR2 800 PC2-6400 and will run at that speed on a compatible board

Is the voltage compatible with standard desktop DDR2 slots?

The kit operates at 1.80V, which is the standard voltage for DDR2 UDIMM desktop memory

Do I need to enable any special BIOS setting for the CL6 timing?

Most boards apply CL6 automatically at DDR2 800; if not, set the timing manually in the BIOS memory options
