Product Description
The IBM 12R9283 is a specialized memory module with a capacity of 256MB, designed to meet the requirements of certain IBM systems that utilize the compact Micro-DIMM form factor. This memory operates at DDR-266MHz speeds, corresponding to the PC2100 standard, and features a 2Rx8 configuration, indicating it is dual-ranked with 8-bit memory chips. The CAS Latency (CL) is rated at 2.5, which is a measure of the delay before the memory module responds to a request. The Micro-DIMM form factor is significantly smaller than standard DIMMs or SO-DIMMs, making it suitable for highly space-constrained devices such as certain laptops, embedded systems, or specialized server configurations where standard memory modules would not fit. The DDR SDRAM technology represents a generation of memory that offers improved performance over older SDRAM by doubling the data transfer rate through its use of both the rising and falling edges of the clock signal. This specific part number, 12R9283, is crucial for ensuring compatibility with the intended IBM hardware. Upgrading or replacing memory in systems that require Micro-DIMMs necessitates using modules that precisely match the specifications, including capacity, type, speed, and form factor, to guarantee proper operation and system stability.
