2-power 2P-CM997 - 4 GB - 1 x 4 GB - DDR2 - 800 MHz

The 2-POWER 2P-CM997 brings a rare combination of high capacity and proven DDR2 reliability to legacy desktop platforms. While most DDR2 modules top out at 2GB per stick, this single 4GB DIMM doubles the memory ceiling of many older systems, enabling smoother multitasking, faster application loading, and extended usability for aging hardware. Built around a dual-rank x8 configuration, it delivers stable performance at 800MHz with CL6 latency, making it a practical upgrade for workstations and desktops that still rely on DDR2 architecture.

Highlights

• 4GB capacity in a single module – maximizes memory density for DDR2 systems
• 800MHz speed with PC2-6400 specification – balanced bandwidth for everyday computing
• 240-pin DIMM form factor – fits standard desktop motherboards
• Non-ECC, unbuffered design – compatible with consumer and business desktops
• Dual rank (2Rx8) organization – ensures broad chipset compatibility
• 1.8V operating voltage – meets JEDEC DDR2 standards
• CL6 latency – responsive performance for legacy applications

In daily use

Installing the 2P-CM997 is straightforward: align the module with the DIMM slot, press firmly until the retaining clips snap into place, and the system will automatically detect the new capacity. Users can expect snappier response when running multiple browser tabs, office suites, or lightweight virtual machines on older desktops. The module's dual-rank design often improves memory interleaving on compatible chipsets, yielding a modest performance boost over single-rank alternatives. For systems with four DIMM slots, pairing two of these modules provides 8GB of total memory – a significant leap for DDR2-era machines.
