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

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
