  • Capacity1GB
  • SpeedDDR2 533 (PC2 4200)
  • CAS LatencyCL4
  • Voltage1.8V
  • ECCNo
  • Buffered/RegisteredUnbuffered

Capacity 1GB

  • Adds 1 GB of DDR2 memory for smoother multitasking
  • Runs at 533 MHz PC2-4200 speed with CL4 latency
  • Operates at standard 1.8 V JEDEC voltage for broad compatibility
  • Unbuffered non-ECC 240-pin UDIMM fits typical desktop slots
  • JEDEC and RoHS compliant for warranty-safe upgrades

Single-Module DDR2 Upgrade

This OWC module adds one gigabyte of DDR2 memory to a desktop that uses 240-pin unbuffered DIMMs. It is built to JEDEC-standard PC2-4200 timings and runs at the stock 1.8 volt level without ECC or registration. The single-rank 1Rx8 layout keeps the electrical load light for older chipsets.

Passive Cooling and Standard Power

No heat spreader is fitted, so the module relies on normal case airflow and runs silently. Power draw stays at the JEDEC-defined 1.8 volts, matching the voltage the motherboard already supplies for DDR2. There are no LEDs or active cooling components to add noise or extra current draw.

533 MT/s PC2-4200 Speed Rating

The module operates at 533 MT/s with a CAS latency of CL4, the exact speed grade labelled PC2-4200. If your system requires this specific DDR2 frequency and timing, the part will slot in and run at its rated settings; if the board needs a different DDR2 speed grade, this module will not match the required specification.

Perguntas sobre este artigo

Will this module work in a motherboard that only supports DDR2 533?

The module runs at DDR2 533 (PC2-4200) with CL4 timing and 1.8V, matching the motherboard specification exactly.

Does the 240-pin DIMM fit a standard desktop DDR2 slot?

Yes, it uses the 240-pin UDIMM form factor for unbuffered desktop memory.

Is ECC required for this upgrade?

No, the module is non-ECC and unbuffered, which is typical for consumer desktops.
