4454-7038 - IBM 8GB Kit (4 X 2GB) DDR-266MHz PC2100 ECC Registered CL2.5 208-Pin DIMM Memory

Description

This IBM memory kit, identified by SKU 4454-7038, offers a total of 8GB of memory, distributed across four 2GB Micro-DIMM modules. Each module is specified as 2Rx8, indicating a dual-rank configuration with eight memory chips per rank, which can enhance performance in certain system architectures. The memory operates at a speed of 266MHz, a common specification for DDR memory of its era, and features a CAS Latency (CL) of 2.5, defining the number of clock cycles required to access data. The Micro-DIMM form factor suggests that this memory is intended for compact or specialized systems, such as certain laptops, small form factor PCs, or embedded devices where standard DIMMs might not fit. The DDR designation confirms it is part of the Double Data Rate Synchronous Dynamic Random-Access Memory family, which was a significant advancement over earlier SDRAM by doubling the data transfer rate. This kit is specifically designed to be compatible with IBM systems that utilize this particular memory type and form factor. Users should verify system compatibility before purchase, as DDR memory and Micro-DIMMs are not interchangeable with newer DDR generations (DDR2, DDR3, DDR4, DDR5) or standard DIMM/SO-DIMM form factors. The 4454-7038 provides a straightforward upgrade path for systems requiring additional memory capacity within these constraints.
