The Kingston memory module KTD-WS670/1G is a DDR2 module with a memory capacity of 1 GB, specifically developed for use in servers and PCs. It is a 240-pin DIMM module designed for systems requiring a buffered memory architecture (Registered, buffered). The module configuration is 128M x 72, indicating a memory interface width of 72 bits. The memory voltage is 1.8 V, and the CAS latency is 3, ensuring efficient data access time. The bus clock rate is specified as 400 MHz, defining the maximum transfer rate of the module.

Applications
This module is designed for use in specific server and workstation systems, particularly in Dell systems such as PowerEdge 1800, 1850, 1855, 2800, 2850, 6800, 6850, SC1420, SC1425, as well as Precision Workstation 470/470n and 670/670n. Compatibility has been tested in these systems, ensuring 100% functionality. The module number KTD-WS670/1G is part of Kingston's System Specific Memory product family, developed for specific hardware configurations.

Features and Specifications in Detail
The module features ECC error detection (Error Correcting Code), which detects and corrects errors during data transfer and storage. This is particularly important in server environments, where data integrity and system stability are critical. The buffered memory architecture (Registered) enables stable memory control in systems with multiple memory modules by regulating data transfer through a register buffer stage. The memory layout specification of 1 x 1 GB means the module is configured as a single 1 GB unit.

Technology Explained Simply
The DDR2 technology (Double Data Rate 2) enables higher data transfer rates compared to previous memory technologies by transferring data on both the rising and falling edges of each clock signal. The CAS latency of 3 indicates the number of clock cycles required to access a memory cell, which is relevant for system responsiveness. The memory voltage of 1.8 V is standard for DDR2 modules and ensures efficient power supply. The 72-bit interface includes 64 bits for data and 8 bits for ECC error correction.

Compatibility and Accessories
The module is specifically designed for the mentioned Dell systems and has been tested in them. Compatibility is documented with model numbers A0374933, A0374937, A0377943, A0380698, A0395465, A0396705, A0396708, A0422904, A0428480, A0466926, and A0466927. It is not suitable for general PC systems without specific requirements for buffered memory architecture and ECC functionality.

Installation and Mounting
Installation is performed by inserting the 240-pin DIMM module into the corresponding memory socket of the system. The connector is designed so that the module can only be inserted in the correct orientation. No additional tools are required, as the module is secured in the socket by pressure. Physical fit and electrical compatibility are ensured by the specific development for the mentioned systems.

Operational Advantages
Using this module in compatible systems ensures high system stability and data integrity, particularly through the ECC function. Kingston Technology's lifetime warranty provides additional security for operation in critical environments. The specific development for the mentioned systems minimizes the risk of compatibility issues and ensures reliable performance in server and workstation applications.
