• Various C-States (C0 through C6)
The processor does not support Hyper-Threading (HT).

SoC SATA Controllers
The SoC has two independent integrated SATA host controllers. The SATA2 controller
supports Direct Memory Access (DMA) operation up to four ports and supports data transfer
rates of 3.0 Gb/s (300 MB/s) and 1.5 Gb/s (150 MB/s). The SATA3 controller in addition to
legacy data rates supports data rates of up to 6 Gb/s (600 MB/s). The SATA3 controller is the
legacy IDE controller and has two ports. Both SATA controllers contain two modes of
operation; a native mode and an Advanced Host Controller Interface (AHCI) mode using
memory space. Software that uses legacy mode does not have AHCI capabilities.

Memory
4.2.3.1
DRAM Memory
The Mohon Peak board provides four DDR3 DIMM sockets for a dual channel memory system
(two UDIMMs per channel). The characteristics of the supported memory include:
• DDR3 (1.5V) or DDR3L (1.35V) UDIMMs
• ECC is supported
• 1066/1333/1600 MT/s data rates
• Single or double rank x8 data width (x16 not supported)
• 1/2/4/8/16 GB UDIMM sizes
The blue sockets (DDR3_A1 and DDR3_B1) should always be populated before the black
sockets (DDR3_A2 and DDR3_B2).
The first memory channel is designated as DDR3_A* (one blue, one black socket), and the
second channel is DDR3_B* (one blue, one black socket). When populating memory in both
channels, channel A and channel B must be populated identically.
