Product Description
The IBM 09P8156 is a 256 Megabyte (MB) SDRAM (Synchronous Dynamic Random-Access Memory) module, specifically identified with a PC-100 speed rating. This indicates that the module is designed to operate at a clock speed of 100MHz, which was a common standard for SDRAM in the late 1990s and early 2000s. SDRAM was a significant advancement over older asynchronous DRAM, offering synchronized operation with the system clock for improved performance. This module is a DIMM (Dual In-line Memory Module), the standard form factor for desktop and server memory during the SDRAM era. The 'IBM' branding suggests it was either manufactured by IBM or intended for use in IBM's server or workstation product lines from that period. With a capacity of 256MB, it would have been a typical upgrade component for systems of its time, allowing for increased multitasking capabilities and the ability to run more demanding software. Given its PC-100 specification, this memory is only compatible with motherboards and chipsets that support SDRAM at this speed. It is not compatible with modern DDR, DDR2, DDR3, or DDR4 memory standards. The IBM 09P8156 is a component relevant for maintaining or restoring older IBM systems that require this specific type of memory.
