Overview
16 Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
— UDIMMs x8, x16
— RDIMMs x4, x8
— LRDIMM x4, x8 (2-Gb and 4-Gb only)
• Up to 8 ranks supported per memory channel, 1, 2 or 4 ranks per DIMM
• Open with adaptive idle page close timer or closed page policy
• Per channel memory test and initialization engine can initialize DRAM to all logical
zeros with valid ECC (with or without data scrambler) or a predefined test pattern
• Isochronous access support for Quality of Service (QoS), native 1 and 2 socket
platforms - Intel® Xeon® processor E5-1600 and E5-2600 product families only
• Minimum memory configuration: independent channel support with 1 DIMM
populated
• Integrated dual SMBus master controllers
• Command launch modes of 1n/2n
• RAS Support (including and not limited to):
— Rank Level Sparing and Device Tagging
— Demand and Patrol Scrubbing
— DRAM Single Device Data Correction (SDDC) for any single x4 or x8 DRAM
device failure. Independent channel mode supports x4 SDDC. x8 SDDC
requires lockstep mode
— Lockstep mode where channels 0 & 1 and channels 2 & 3 are operated in
lockstep mode
— The combination of memory channel pair lockstep and memory mirroring is not
supported
— Data scrambling with address to ease detection of write errors to an incorrect
address.
— Error reporting via Machine Check Architecture
— Read Retry during CRC error handling checks by iMC
— Channel mirroring within a socket Channel Mirroring mode is supported on
memory channels 0 & 1 and channels 2 & 3
— Corrupt Data Containment
—MCA Recovery
• Improved Thermal Throttling with dynamic Closed Loop Thermal Throttling (CLTT)
• Memory thermal monitoring support for DIMM temperature via two memory
signals, MEM_HOT_C{01/23}_N
1.2.2 PCI Express*
• The PCI Express* port(s) are fully-compliant to the PCI Express* Base
Specification, Revision 3.0 (PCIe* 3.0)
• Support for PCI Express* 3.0 (8.0 GT/s), 2.0 (5.0 GT/s), and 1.0 (2.5 GT/s)
• Up to 40 lanes of PCI Express* interconnect for general purpose PCI Express*
devices at PCIe* 3.0 speeds that are configurable for up to 10 independent ports
• 4 lanes of PCI Express* at PCIe* 2.0 speeds when not using DMI2 port (Port 0),
also can be downgraded to x2 or x1
• Negotiating down to narrower widths is supported, see Figure 1-3:
