Electrical Specifications
82 Intel® Xeon® Product 2800/4800/8800 v2 Product Family
Datasheet Volume One, February 2014
Mixing processors of different steppings but the same model (as per CPUID instruction)
is supported. Details regarding the CPUID instruction are provided in the AP-485,
Intel® Processor Identification and the CPUID Instruction application note.
6.6 Flexible Motherboard Guidelines (FMB)
The Flexible Motherboard (FMB) guidelines are estimates of the maximum values the
Intel® Xeon® E7 v2 processor will have over certain time periods. The values are only
estimates and actual specifications for future processors may differ. Processors may or
may not have specifications equal to the FMB value in the foreseeable future. System
designers should meet the FMB values to ensure their systems will be compatible with
future Intel® Xeon® E7 v2 processors.
6.7 Absolute Maximum and Minimum Ratings
Table 6-9 specifies absolute maximum and minimum ratings. 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.
Although the processor contains protective circuitry to resist damage from Electro-
Static Discharge (ESD), precautions should always be taken to avoid high static
voltages or electric fields.
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
Section 6.12.5. Excessive overshoot or undershoot on any signal will likely result in permanent damage to
the processor.
6.7.1 Storage Conditions Specifications
Environmental storage condition limits define the temperature and relative humidity
limits to which the device is exposed to while being stored in a Moisture Barrier Bag.
The specified storage conditions are for component level prior to board attach (see
notes in Table 6-10 for post board attach limits).
Table 6-10 specifies absolute maximum and minimum storage temperature limits which
represent the maximum or minimum device condition beyond which damage, latent or
otherwise, may occur. The table also specifies sustained storage temperature, relative
humidity, and time-duration limits. These limits specify the maximum or minimum
