Description

The Dell J0201 is a 256MB Unbuffered Dual In-line Memory Module (UDIMM) designed to upgrade or replace memory in compatible Dell computer systems. It operates at a DDR-400MHz speed, providing a noticeable performance boost for everyday computing tasks, multitasking, and applications that benefit from increased memory bandwidth. The module's 1 Rank x 8 Banks (1Rx8) configuration is standard for many desktop and entry-level server applications of its era. With a CAS Latency (CL) of 3, this memory module offers a relatively fast response time for its specifications, contributing to smoother system operation. The UDIMM form factor is common in non-ECC environments, typically found in standard desktop PCs and some workstations where the highest levels of data integrity protection are not the primary concern. Its 2.5V operating voltage is characteristic of DDR memory technology. This 256MB module is a straightforward way to enhance the memory capacity of older Dell systems that support DDR-400MHz RAM. It is particularly useful for systems that may be experiencing performance bottlenecks due to insufficient RAM, allowing for improved application loading times and overall system responsiveness. Ensuring compatibility with the specific Dell system model is recommended before installation.
