Description

The IBM FC1940 is a 1GB Registered DIMM (RDIMM) module, part of the DDR SDRAM family, designed to enhance the memory capacity of compatible IBM server systems. It operates at a clock speed of 266MHz, corresponding to the PC2100 standard, offering a solid level of performance for various server workloads. The RDIMM design incorporates a register chip that buffers address and command signals, reducing the electrical load on the memory controller and enabling systems to support larger amounts of RAM and potentially higher memory speeds. This module is configured as 1Rx4, meaning it is single-ranked with a memory chip data width of x4. Single-rank modules are common and provide reliable performance. The CAS Latency (CL) is set at 2.5, indicating the number of clock cycles required to access a particular memory column after a row has been activated. This timing parameter is a key factor in memory performance. As an IBM-branded component, the FC1940 is built to meet the stringent reliability and compatibility standards required for server hardware. It supports ECC (Error-Correcting Code) functionality, which is essential for maintaining data integrity in critical server applications by detecting and correcting single-bit memory errors. The standard 2.5V operating voltage is characteristic of DDR memory modules.
