3.2.4.1.1
Phase Shedding Configuration Option in BIOS Setup
Intel has added a user configurable option called “Phase Shedding” to BIOS Setup. By default, this option is
configured to “Disabled”, providing maximum VR power which mitigates possible instability issues when using
LRDIMMs greater than 16 GB or 3 DPC memory configurations. This option should only be “Enabled” for
optimized power in 1DPC and 2DPC configurations and when using LRDIMM sizes 16GB and smaller.
Note: The Phase Shedding BIOS setup option can be found in BIOS revision 02.02.0002 and later.
3.2.4.2
Memory Slot Identification and Population Rules
Note: Although mixed DIMM configurations may be functional, Intel only performs platform validation on
systems that are configured with identical DIMMs installed.
Each installed processor provides four channels of memory. On the Intel
®
Server Board S2600GZ
each memory channel supports three memory slots, for a total possible 24 DIMMs installed. On the
Intel
®
Server Board S2600GL each memory channel supports 2 memory slots, for a total possible 16
DIMMs installed.
System memory is organized into physical slots on DDR3 memory channels that belong to processor
sockets.
The memory channels from processor socket 1 are identified as Channel A, B, C and D. The memory
channels from processor socket 2 are identified as Channel E, F, G, and H.
