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.

 through 

 list the DC specifications for the Intel Itanium processor 

9300 series and are valid only while meeting specifications for case temperature, clock 
frequency, and input voltages.

The following notes apply:

• Unless otherwise noted, all specifications in the tables apply to all frequencies
• Unless otherwise noted, these specifications are based on characterized data from 

silicon measurements.

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 
stock-keeping units (SKUs). Current specifications are identified for each processor 
SKU separately.
