Electrical Specifications
Notes:
1.
For functional operation, all processor electrical, signal quality, mechanical, and thermal specifications must be satisfied.
2.
Overshoot and undershoot voltage guidelines for input, output, and I/O signals are outlined in
. Excessive
overshoot or undershoot on any signal will likely result in permanent damage to the processor.

Flexible Motherboard Guidelines
The Flexible Motherboard (FMB) guidelines are estimates of the maximum ratings that
the processor will have over certain time periods. The ratings are only estimates as
actual specifications for future processors may differ. The processor may or may not
have specifications equal to the FMB value in the foreseeable future. System designers
should meet the FMB values to ensure that their systems will be compatible with future
releases of the Intel® Itanium® processor 9300 series.

FMB Voltage Specification values apply to both the 130W and 155W/185W processor
