Overview of NQ5000X - Intel 5000X Memory Controller Hub (MCH) Dual-Core Xeon 5000/5100 1432 FC-BGA
The NQ5000X is Intel's 5000X Memory Controller Hub, the workstation-class host bridge of the 5000-series server chipset. It provides the processor interface, a four-channel Fully Buffered DIMM memory controller, PCI Express, the ESI link to the I/O hub, and SMBus, serving dual-processor platforms built on Dual-Core Intel Xeon 5000 and 5100 series processors across two independent front-side buses. It arrives in a large 1432-ball Flip Chip BGA measuring 42.5 x 42.5mm, the full-size member of the family aimed at memory-rich workstations and servers.
Key Features
- Dual independent FSB - two point-to-point processor buses at up to 1333 MT/s, one per socket, for theoretical bandwidth of 17 GB/s at 1066 and 21 GB/s at 1333.
- Four FB-DIMM channels - DDR2-533 and DDR2-667 Fully Buffered DIMMs, up to four dual-rank DIMMs per channel across two branches, for as much as 64 GB.
- PCI Express 1.0a - a high-performance x16-class graphics port plus additional PCIe ports and the PCIe-based ESI link to the I/O controller hub.
- Advanced memory RAS - SEC/DED ECC, Single Device Data Correction for x4 and x8 DRAM, memory mirroring in a RAID-1 branch arrangement, and both patrol and demand scrubbing.
- Integrated data engines - a snoop filter and an integrated DMA engine help sustain throughput under heavy multiprocessor load.
- Management and I/O links - an ESI link to the I/O controller hub and an SMBus port for platform management complete the hub's connectivity.
- 1432-ball FC-BGA - a 42.5mm flip-chip package with 1.092mm ball pitch for dense dual-processor boards.
Typical Applications
- Dual-processor workstations - memory-intensive engineering, rendering, and scientific workstations using Xeon 5000 or 5100 processors.
- Performance servers - DP servers needing the full four-channel FBDIMM capacity and PCIe fan-out.
- Legacy platform support - sustaining deployed 5000X-based systems that still carry production workloads.
Unique Advantages
- Full memory reach - four FB-DIMM channels and up to 64 GB give the 5000X far more capacity than the value 5000V, suiting large in-memory datasets.
- Mirroring for uptime - RAID-1 memory mirroring, available on this workstation MCH, protects against uncorrectable memory failures.
- Scrubbing built in - patrol and demand scrubbing actively correct latent single-bit errors before they accumulate.
Why Choose NQ5000X?
The NQ5000X is the right memory controller hub when a dual-processor Xeon 5000 or 5100 design needs maximum FBDIMM capacity and strong memory reliability rather than the trimmed value configuration. Its four-channel memory, RAID-1 mirroring, SDDC, and scrubbing make it a dependable foundation for workstations and servers, and a necessary part for maintaining installed 5000X platforms.
