Brand: Rambus · SKU: RDRAM-PC800-256MB · MPN: PC800-RDRAM · Category: Components
Rambus Dynamic Random Access Memory (RDRAM) is a high-speed synchronous DRAM technology developed by Rambus Inc. in the late 1990s. This specific module is a PC800 standard RIMM (Rambus In-line Memory Module), featuring a 184-pin form factor and a 16-bit bus. Operating at a clock frequency of 400 MHz, it delivers an effective data rate of 800 MHz through Double Data Rate (DDR) techniques, providing a peak bandwidth of 1.6 GB/s per channel. RDRAM was famously utilized in Intel Pentium 4 systems (specifically those using the Intel 850 chipset) and the Nintendo 64 game console. Unlike standard SDRAM, RDRAM requires a heat spreader due to its high power consumption and thermal output. It also requires a continuity module (C-RIMM) in empty slots to maintain the serial signal loop.

RDRAM was designed to overcome the memory bottlenecks of the late 90s by using a narrow, high-speed serial bus architecture. It was the primary memory standard for the early Intel Pentium 4 era but was eventually superseded by DDR SDRAM due to higher manufacturing costs and licensing fees.
