Intel® Xeon® Processor E5-1600 v2/E5-2600 v2 Product Families
Datasheet Volume One of Two
• Static lane numbering reversal support
• Supports DMI2 virtual channels VC0, VC1, VCm, and VCp
1.2.4
Intel® QuickPath Interconnect (Intel® QPI)
• Compliant with Intel QuickPath Interconnect v1.1 standard packet formats
• Implements two full width Intel QPI ports
• Full width port includes 20 data lanes and 1 clock lane 
• 64 byte cache-lines
• Isochronous access support is not available on any CPU model containing two home 
agents.
Note: RAS support depends on processor SKU. For example, Workstation SKUs do 
not support sparing or tagging, lockstep mode, mirroring mode, channel 
mirroring mode within a socket, error containment.
• Home snoop based coherency
• 4-bit  Node  ID
• 46-bit physical addressing support
• No Intel QuickPath Interconnect bifurcation support
• Differential signaling
• Forwarded clocking
• Up to 8.0 GT/s data rate (up to 16 GB/s direction peak bandwidth per port) 
— All ports run at same operational frequency
— Reference Clock is 100 MHz
— Slow boot speed initialization at 50 MT/s
• Common reference clocking (same clock generator for both sender and receiver)
• Intel® Interconnect Built-In-Self-Test (Intel® IBIST) for high-speed testability
• Polarity Inversion and Lane reversal (Rx side only)
1.2.5
Platform Environment Control Interface (PECI)
The PECI is a one-wire interface that provides a communication channel between a 
PECI client (the processor) and a PECI master (the PCH).  
• Supports operation at up to 2 Mbps data transfers
• Link layer improvements to support additional services and higher efficiency over 
PECI 2.0 generation
• Services include CPU thermal and estimated power information, control functions 
for power limiting, P-state and T-state control, and access for Machine Check 
Architecture registers and PCI configuration space (both within the processor 
package and downstream devices)
• PECI address determined by SOCKET_ID configuration
• Single domain (Domain 0) is supported
