Electrical Specifications
of the other components is capable of accepting an input of the appropriate voltage. Similar
considerations must be made for TCK, TMS, and TRST#. Two copies of each signal may be
required with each driving a different voltage level.
2.9
Mixing Processors
Intel only supports and validates dual processor configurations in which both processors operate
with the same front side bus frequency, core frequency, VID range, 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 [Note: Processors within a system must operate at the same
frequency per bits [15:8] of the IA32_FLEX_BRVID_SEL MSR; however this does not apply to
frequency transitions initiated due to thermal events, Enhanced Intel SpeedStep technology
transitions, or assertion of the FORCEPR# signal (see Chapter 6)]. Not all operating systems can
support dual processors with mixed frequencies. Intel does not support or validate operation of
processors with different cache sizes. Mixing processors of different steppings but the same model
(as per CPUID instruction) is supported. Please see the 64-bit Intel Xeon Processor with 800
MHz System Bus (1 MB and 2 MB L2 Cache Versions) Specification Update (see Section 1.2) for
the applicable mixed stepping table. Details regarding the CPUID instruction are provided in the
Intel
Processor Identification and the CPUID Instruction application note. Low-voltage (LV),
mid-voltage (MV), and full power 64-bit Intel Xeon processors with 2 MB L2 cache should not be
mixed within a system.

Absolute Maximum and Minimum Ratings
Table 2-7 specifies absolute maximum and minimum ratings. Within functional operation limits,
functionality and long-term reliability can be expected.
At conditions outside functional operation condition limits, but within absolute maximum and
minimum ratings, neither functionality nor long term reliability can be expected. If a device is
returned to conditions within functional operation limits after having been subjected to conditions
outside these limits, but within the absolute maximum and minimum ratings, the device may be
functional, but with its lifetime degraded depending on exposure to conditions exceeding the
functional operation condition limits.
At conditions exceeding absolute maximum and minimum ratings, neither functionality nor long-
term reliability can be expected. Moreover, if a device is subjected to these conditions for any
length of time then, when returned to conditions within the functional operating condition limits, it
will either not function, or its reliability will be severely degraded.
Although the processor contains protective circuitry to resist damage from static electric discharge,
precautions should always be taken to avoid high static voltages or electric fields.
