Kingston KVR100X64SC2/256 ValueRAM SO-DIMM 256MB PC100 content_copy

The Kingston ValueRAM memory module with manufacturer number KVR100X64SC2/256 is a 256 MB (0.25 GB) SD-RAM module in 144-pin SO-DIMM format, specifically designed for use in notebooks and compact computers. It is based on SDRAM technology with a memory clock frequency of 100 MHz and is designed for systems requiring PC100 memory compatibility. The module is not equipped with ECC functionality, making it suitable for applications where error correction is not required, such as in standard notebooks or entry-level systems. The memory interface has a width of 64 bits, which determines the data transfer rate within the system. The internal memory access speed is 8 ns, influencing the module's response time during read and write operations. The operating voltage is 3.3 V, typical for SO-DIMM modules of the PC100 generation. The module's contacts are gold-plated, ensuring a reliable and long-lasting connection to the memory socket.

Applications
This memory module is primarily intended for notebooks and small form factor computers that support a 144-pin SO-DIMM memory socket. It is suitable for systems that, due to their design or available memory slots, cannot use standard DIMMs. The memory capacity of 256 MB was sufficient for basic operating systems and applications in the past, but is often inadequate for modern operating systems and software today. The modules are designed for systems supporting a clock frequency of 100 MHz, which was common in older notebooks and computers from the early 2000s.

Features and Specifications in Detail
The module features a CAS latency of 2 (CL2), meaning it requires two clock cycles to respond to a memory access. This is a standard value for PC100 modules and corresponds to the performance requirements of that era. Electrical specifications include a minimum CLK cycle time of 10 ns and a maximum row cycle time of 70 ns. Power supply is provided via a single voltage source of +3.3 V, with a tolerance of ±0.3 V allowed. The maximum power consumption is 3.696 W during operation. The modules comply with industry-standard requirements and are designed for use in systems meeting the PC100 specification.

Technical Explanation
SDRAM (Synchronous Dynamic Random Access Memory) is a type of memory that operates in sync with the system clock, enabling more efficient data transfer. The SO-DIMM format (Small Outline Dual Inline Memory Module) is a more compact variant of the standard DIMM, specifically developed for notebooks and small computers. The 144-pin configuration is typical for the PC100 generation and allows connection to corresponding memory sockets. The gold plating of the contacts ensures good electrical conductivity and minimizes oxidation, extending the module's lifespan. The memory capacity of 256 MB corresponds to a 32M x 64-bit layout, meaning the memory cells are organized in 32 million blocks, each with 64 bits.

Compatibility and Accessories
The module is compatible with systems that support a 144-pin SO-DIMM memory socket and require PC100 memory frequency. It is not suitable for systems with higher memory frequencies (e.g., PC133) or other form factors (e.g., 200-pin SO-DIMM). The modules are part of Kingston's ValueRAM series, known for providing a cost-effective yet reliable memory solution. There are no specific accessories included with or recommended for this module. Compatibility is limited to the specifications mentioned.

Installation and Mounting
Installation is performed by inserting the module into the corresponding SO-DIMM socket of the computer. The contacts must be clean and free of contamination to ensure a secure connection. The module is secured in the socket by a retention clip, which automatically locks after insertion. No additional tools or components are required for mounting. The maximum module height is 31.75 mm (1.250 inches), which is sufficient for most notebooks and small computers.

Operational Advantages
The module provides reliable memory performance for systems meeting the PC100 specification. The use of gold-plated contacts and high-quality SDRAM chips ensures long life and stable operating characteristics. Kingston Technology's lifetime warranty underscores the quality of the ValueRAM series. The modules are easy to install and require no additional BIOS settings, as they automatically adapt to the system. Memory performance is sufficient for basic applications, but not suitable for modern, resource-intensive software.
