Intel D850MV Socket 478 ATX Motherboard i850 Chipset RDRAM DDR PC800

Intel D850MV Socket 478 ATX Motherboard i850 Chipset RDRAM DDR PC800

The Intel D850MV is an ATX desktop motherboard built around Intel's i850 chipset, designed to support Socket PGA478B Pentium 4 processors. It features four RIMM slots for Rambus DRAM (RDRAM PC800), an AGP slot for a dedicated graphics card, and five PCI expansion slots — making it a well-equipped board for early Pentium 4 desktop builds. Integrated LAN and audio are also present on the I/O panel.

Applications

The Intel D850MV was designed for early Pentium 4 desktop systems, representing Intel's platform push around 2001–2002 when the i850 chipset and RDRAM delivered the highest memory bandwidth available for the P4 architecture. RDRAM (Rambus DRAM) was Intel's preferred high-bandwidth memory technology of that era, though it was eventually displaced by DDR SDRAM as DDR chipsets matured and became more cost-effective. This board is well suited for restoring or maintaining period-correct Pentium 4 workstations, as a spare for existing D850MV-based systems, or as a collectible example of Intel's early Socket 478 desktop platform. Legacy system integrators and vintage PC enthusiasts working with early P4 hardware will find this a direct replacement or upgrade path for compatible systems.
