4.7 Processor options
Several Intel Xeon 6500 and Xeon 7500 processor options are available for the x3690 X5, as
listed in Table 4-5.
Table 4-5 x3690 X5 processor options
See 2.2, “Intel Xeon 6500 and 7500 family processors” on page 16 for an in-depth description
of the Intel Xeon 6500/7500 processor family and features.
Most processors support Intel Turbo Boost Technology with a couple of exceptions, as listed
in Table 4-5. When a CPU operates beneath its thermal and electrical limits, Turbo Boost
dynamically increases the processor’s clock frequency by 133 MHz on short and regular
intervals until an upper limit is reached. See 2.2.3, “Turbo Boost Technology” on page 18 for
more information.
With the exception of the X7542, all CPUs that are listed support Intel Hyper-Threading
Technology. Hyper-Threading Technology (HT) is an Intel technology that is used to improve

Clarification:
򐂰 The Xeon E6510 does not support the use of the MAX5 memory expansion unit.
򐂰 The x3690 X5 announcement letter incorrectly reports that the L3 cache of the X7542 is
12 MB.
򐂰 Also, the announcement letter incorrectly states that the E6540 does not have Turbo
Boost mode.
