Intel BX80637G2010 1.2.2 PCI Express*

Introduction

12 Datasheet, Volume 1

• Support memory configurations that mix DDR3 DIMMs/DRAMs with DDR3L

DIMMs/DRAMs running at 1.5 V

• The type of the DIMM modules supported by the processor is dependent on the PCH

SKU in the target platform:

— Desktop PCH platforms support non-ECC UDIMMs only

— All In One platforms (AIO) support SO-DIMMs

• Theoretical Maximum Memory Bandwidth:

— 10.6 GB/s in single-channel mode or 21.3 GB/s in dual-channel mode assuming

DDR3 1333 MT/s

— 12.8 GB/s in single-channel mode or 25.6 GB/s in dual-channel mode assuming

DDR3 1600 MT/s

• Processor on-die Reference Voltage (VREF) generation for both DDR3 Read

(RDVREF) and Write (VREFDQ)

• 1Gb, 2Gb, and 4Gb DDR3 DRAM device technologies are supported

— Using 4Gb DRAM device technologies, the largest memory capacity possible is

32 GB, assuming Dual Channel Mode with four x8 dual ranked DIMM memory

configuration

• Up to 64 simultaneous open pages, 32 per channel (assuming 8 ranks of 8 bank

devices)

• Command launch modes of 1N/2N

• On-Die Termination (ODT)

• Asynchronous ODT

•Intel

® Fast Memory Access (Intel® FMA):

— Just-in-Time Command Scheduling

—Command Overlap

— Out-of-Order Scheduling

1.2.2 PCI Express*

• The PCI Express* lanes (PEG[15:0] TX and RX) are fully-compliant to the PCI

Express Base Specification, Revision 3.0, including support for 8.0 GT/s transfer

speeds.

• Processor with Desktop PCH Supports (may vary depending on PCH SKUs)

• PCI Express* supported configurations in desktop products

• The port may negotiate down to narrower widths

— Support for x16/x8/x4/x2/x1 widths for a single PCI Express* mode

• 2.5 GT/s, 5.0 GT/s and 8.0 GT/s PCI Express* frequencies are supported

• Gen1 Raw bit-rate on the data pins Gen 2 Raw bit-rate on the data pins of 5.0 GT/s,

resulting in a real bandwidth per pair of 500 MB/s given the 8b/10b encoding used
