Designed specifically for mobile computing environments, this memory features a 200-pin SODIMM form factor that fits standard notebook memory slots. The dual-rank architecture and unbuffered signal processing provide stable data handling without the overhead of error-correcting code, making it a cost-effective solution for general-purpose computing tasks. With a low 1.8V operating voltage, it helps maintain energy efficiency while delivering the performance needed for everyday applications.
Technical Overview
This memory kit delivers 4GB of total capacity through two identical 2GB modules, each operating at 800 MHz with a data bus speed of 400 MHz. The DDR2-800/PC2-6400 standard ensures backward compatibility with systems designed for DDR2 memory, while the CL5 latency timing provides balanced performance for sequential and random access patterns. The dual-rank design allows for efficient memory bank interleaving, which can improve throughput in supported systems.
The electrical specifications include a 1.8V operating voltage, which was standard for DDR2 memory and helps reduce power consumption compared to earlier memory technologies. The unbuffered signal processing means the memory modules communicate directly with the memory controller without intermediate buffering, resulting in lower latency for most operations. This configuration is ideal for notebooks where space and power constraints are primary considerations.

FAQ
What is the total memory capacity of this kit?
This memory kit provides 4GB of total capacity, achieved through two identical 2GB modules. This configuration is designed as a matched pair to ensure compatibility and stable operation in systems that benefit from dual-channel memory configurations when supported by the notebook's chipset and memory controller.
What type of systems is this memory compatible with?
This memory is specifically designed for notebook computers that use DDR2 memory technology with 200-pin SODIMM slots. It is compatible with systems that support the DDR2-800/PC2-6400 memory standard and operate at 1.8V. The memory is unbuffered and non-ECC, making it suitable for consumer and business notebooks from the DDR2 era that don't require error-correcting memory.
What does DDR2-800/PC2-6400 mean?
DDR2-800 refers to the memory technology (Double Data Rate 2) operating at 800 MHz, while PC2-6400 indicates the theoretical peak transfer rate of 6400 MB/s. This memory standard was common in notebook systems from the mid-to-late 2000s and represents the performance ceiling for DDR2 technology in most consumer and business applications.
What is the difference between unbuffered and registered memory?
Unbuffered memory, like this AddOn kit, communicates directly with the memory controller without intermediate buffering, resulting in lower latency for most operations. Registered memory includes a register between the memory modules and controller to improve signal integrity in systems with many memory modules, but adds latency and cost. This unbuffered design is standard for notebook memory where space and power constraints prioritize direct communication.
What does dual-rank architecture mean for performance?
Dual-rank architecture means each memory module has two independent sets of memory banks that can be accessed separately. In systems that support rank interleaving, this allows the memory controller to access one rank while another is refreshing, potentially improving memory bandwidth utilization. For DDR2 systems, dual-rank modules were common for higher-capacity memory like these 2GB modules.
Is this memory compatible with desktop computers?
No, this memory uses a 200-pin SODIMM form factor specifically designed for notebook computers. Desktop systems typically use 240-pin DIMM modules with different physical dimensions and pin configurations. Attempting to install SODIMM memory in a desktop system would not be physically possible without an adapter, and even with an adapter, compatibility would be unlikely due to different electrical requirements and form factor constraints.
