Description
The IBM 7039-4490 is a memory upgrade kit designed to enhance the performance of compatible systems. This kit provides a total of 4GB of Random Access Memory, distributed across four individual 1GB Micro-DIMM modules. The memory operates at a speed of 266MHz, offering a balance between performance and compatibility for systems that utilize DDR memory technology. Each module in this kit is configured as 1Rx8, indicating a single rank with an 8-bit data width per chip. This configuration is important for system compatibility and performance optimization. The modules also feature a CAS Latency (CL) of 2.5, which specifies the delay between the memory controller requesting data and the data being available. Lower CAS latency generally translates to faster response times. The Micro-DIMM form factor is a smaller form factor compared to standard DIMMs, often found in compact or specialized computing devices such as certain laptops, small form factor PCs, or embedded systems. The IBM 7039-4490 kit is intended for users who need to expand or replace memory in systems that specifically support DDR-266MHz Micro-DIMMs with these particular specifications.
