PECI Interface
66 Thermal/Mechanical Specifications and Design Guide
7.1.2.6.6 DRAM Channel Temperature Read
This feature enables a PECI host read of the maximum temperature of each channel.
This would include all the DIMMs within the channel and all the ranks with each of the
DIMMs. Channels that are not populated will return the ‘ambient temperature’ on
systems using activity-based temperature estimations or alternatively return a ‘zero’
for systems using sensor-based temperatures.
7.1.2.6.7 Accumulated DRAM Energy Read
This feature allows the PECI host to read the DRAM energy consumed by all the DIMMs
within all the channels or all the DIMMs within just a specified channel. The parameter
field is used to specify the channel index. Units used are defined as per the Package
Power SKU Unit read described in Section 7.1.2.7. This information is tracked by a 32-
bit counter that wraps around. Note that the channel index in Figure 7-15 is specified
as per the index encoding described in Ta b l e 7 - 7 . A channel index of 0x00FF is used to
specify the “all channels” case.
