Introduction The Intel® Core™ i7 processor family for the LGA-2011 socket is the next generation of 64-bit, multi-core desktop processor built on 32-nanometer process technology. Based on the low-power/high performance Intel® Core™ i7 processor microarchitecture, the processor is designed for a two-chip platform as opposed to the traditional three-chip platforms (processor, MCH, and ICH). The two-chip platform consists of a processor and the Platform Controller Hub (PCH) and enables higher performance, easier validation, and improved x-y footprint. Refer to Figure 1-1 for a block diagram of...

System Memory Support • The processor supports 4 DDR3 channels with 1 unbuffered DIMM per channel • Unbuffered DDR3 DIMMs supported • Data burst length of eight cycles for all memory organization modes • Memory DDR3 data transfer rates of 1066, 1333, and 1600 MT/s • DDR3 UDIMM standard I/O Voltage of 1.5 V • 1-Gb, 2-Gb, and 4-Gb DDR3 DRAM technologies supported for these devices: — UDIMMs x8, x16 • Up to 2 ranks supported per memory channel, 1 or 2 ranks per DIMM • Open with adaptive idle page close timer or closed page policy • Command launch modes of 1n/2n • Improved Thermal Throttling...

• Supports receiving and decoding 64 bits of address from PCI Express* — Memory transactions received from PCI Express* that go above the top of physical address space (when Intel VT-d is enabled, the check would be against the translated HPA (Host Physical Address) address) are reported as errors by — Outbound access to PCI Express* will always have address bits 63 to 46 cleared • Re-issues Configuration cycles that have been previously completed with the Configuration Retry status • Power Management Event (PME) functions • Message Signaled Interrupt (MSI and MSI-X) messages • Degraded...

Direct Media Interface Gen 2 (DMI2) • Serves as the chip-to-chip interface to the PCH • The DMI2 port supports x4 link width and only operates in a x4 mode when in DMI2 • Operates at PCIe2 or PCIe1 speeds • Transparent to software • Processor and peer-to-peer writes and reads with 64-bit address support • APIC and Message Signaled Interrupt (MSI) support. Will send Intel-defined “End of Interrupt” broadcast message when initiated by the processor. • System Management Interrupt (SMI), SCI, and SERR error indication • Static lane numbering reversal support • Supports DMI2 virtual channels...

Thermal Management Support • Adaptive Thermal Monitor • THERMTRIP_N and PROCHOT_N signal support • On-Demand mode clock modulation • Open Loop Thermal Throttling and Hybrid OLTT/CLTT support for system memory • Fan speed control with DTS • Two integrated SMBus masters for accessing thermal data from DIMMs • New Memory Thermal Throttling features using MEM_HOT signals Package Summary The processor socket type is noted as LGA2011. The processor package is a 52.5 x 45 mm FC-LGA package (LGA2011). Refer to the processor Thermal Mechanical Specification and Design Guide (see Section 1.7,...

Terminology (Sheet 2 of 3) Term Intel® Virtualization Technology (Intel® VT) Integrated Heat Spreader (IHS) Description Processor virtualization which when used in conjunction with Virtual Machine Monitor software enables multiple, robust independent software environments inside a single platform. Intel® Virtualization Technology (Intel® VT) for Directed I/O. Intel VT-d is a hardware assist, under system software (Virtual Machine Manager or OS) control, for enabling I/O device virtualization. Intel VT-d also brings robust security by providing protection from errant DMAs by using DMA...
