Intel® 5520/5500 Chipset: DatasheetThe Intel® 5520 Chipset I/O Hub (IOH) and Intel® 5500 Chipset IOH components provide a connection point between various I/O components and Intel® QuickPath Interconnect- (Intel® QPI) based processors. The Intel® 5520 Chipset and Intel® 5500 Chipset are combined with Intel® Xeon® processor 5500 series in their respective two socket platforms. The Intel® Xeon® 5500 Platform consists of the Intel Xeon processor 5500 series, the Intel 5520 Chipset IOH), the Intel 5500 Chipset IOH, the I/O Controller Hub (Intel® ICH9/ICH10), and the I/O subsystem. The processor includes an Integrated Memory Controller (IMC) that resides within the processor package. This platform is the first single processing platform that introduces the Intel QPI, Intel’s next generation point-to-point system interconnect interface and replaces the Front Side Bus. Note: In this document the term IOH refers to the Intel 5520 Chipset I/O Hub (IOH) and Intel 5500 Chipset I/O Hub (IOH). Note: Unless otherwise specified, ICH or ICH9/ICH10 refers to the Intel® 8201IB ICH9, Intel® 8201IR ICH9R, Intel® 82801JIB ICH10, Intel® 82801JIR ICH10R I/O Controller Hub 9/10 components.Read the full Intel® 5520/5500 Chipset Datasheet.
