Product Description
The IBM 09P3908 is a 256MB memory module that utilizes SDRAM (Synchronous Dynamic Random-Access Memory) technology. It operates at a clock speed of 100MHz, designated as PC-100. This module features a standard 168-pin DIMM form factor, which was common for SDRAM memory used in computers from the late 1990s and early 2000s. It is specified as non-ECC (Non-Error-Correcting Code) and unbuffered, meaning it does not have error detection or correction capabilities and connects directly to the memory controller. The PC-100 rating indicates the module's bandwidth and speed, providing a data transfer rate suitable for the computing platforms of its time. The 256MB capacity offers a basic level of memory expansion, which could improve system performance for tasks such as running basic applications or multitasking with a limited number of programs. This type of memory is distinct from later DDR SDRAM generations, which use different pin counts and signaling methods. This specific part number, 09P3908, suggests it is intended for compatibility with particular IBM systems, likely older servers or workstations. Users looking to purchase this module should confirm that their system explicitly supports PC-100 168-pin unbuffered non-ECC SDRAM DIMMs and that the total installed memory does not exceed the system's maximum supported capacity. It represents a component for maintaining or upgrading legacy IBM hardware.
