Product Description
The IBM 9111-4443 is a 512MB memory kit specifically designed to meet the requirements of certain IBM systems that utilize the compact Micro-DIMM form factor. This memory module operates at DDR-266MHz speeds, also known as PC2100, providing a solid performance baseline for systems that support this standard. The 2Rx8 configuration indicates that the module is dual-ranked, with each rank utilizing x8 DRAM chips, which can influence how the memory controller accesses data and potentially impact performance in certain scenarios. Key specifications include a CAS Latency (CL) of 2.5, which refers to the number of clock cycles it takes for the memory module to respond to a column address command. Lower latency generally translates to faster data access. The Micro-DIMM form factor is significantly smaller than standard DIMMs, making it suitable for space-constrained devices such as certain laptops, small form factor PCs, or specialized IBM server components where physical dimensions are a critical design consideration. This memory kit is intended for users who need to upgrade or replace memory in compatible IBM systems. Ensuring the correct form factor (Micro-DIMM) and specifications (DDR-266MHz, 2Rx8, CL2.5) is crucial for system compatibility and optimal performance. The 512MB capacity provides a modest but essential boost for systems that may have limited built-in memory.
