Flexible Motherboard Guidelines
The Flexible Motherboard (FMB) guidelines are estimates of the maximum ratings that
the Intel® Xeon® processor 7500 series will have over certain time periods. The
ratings are only estimates as actual specifications for future processors may differ. The
VR 11.1 specification is developed to meet FMB Voltage Specification values required by
all Intel® Xeon® processor 7500 series SKUs.

Reserved (RSVD) or Unused Signals
All Reserved signals must be left unconnected on the motherboard. Any deviation in
connection of these signals to any power rail or other signals can result in component
malfunction or incompatibility with future processors. See
connection of these signals to any power rail or other signals can result in component
malfunction or incompatibility with future processors. See
listing of the processor and the location of all signals, including RSVD signals.
Unused Intel® QPI or Intel® SMI input ports may be left as no-connects.
2.12
Test Access Port Connection
The recommended TAP connectivity will be detailed in an upcoming document release.
2.13
Mixing Processors
Intel supports and validates multiple processor configurations only in which all
processors operate with the same Intel® QPI frequency, core frequency, power
segment, have the same number of cores, and have the same internal cache sizes.
Mixing components operating at different internal clock frequencies is not supported
and will not be validated by Intel. Combining processors from different power segments
is also not supported.

Processor SPD Interface
The processor SPD Interface is used for memory initialization including the set up and
use of the memory thermal sensor on-board the Intel® 7500 Scalable Memory Buffer.
Base board management controllers (BMC) can use the PECI interface to the SPD
engine for access to this thermal data.

Base board management controllers (BMC) can use the PECI interface to the SPD
engine for access to this thermal data.
The SPD master in the processor supports 100 khz operation and the following set of
commands:
commands:
Send Byte and Receive Byte
Write Byte and Read Byte
Write Word and Read Word
The SPD Interface does not support bus arbitration or clock stretching.
