Cisco UCS B420 M3 Blade Server
CONFIGURING the SERVER

STEP 2 CHOOSE CPU(S)
The standard CPU features are:
■ Intel Xeon processor E5-4600 series CPUs
■ Core counts of 4, 6, or 8
■ Cache sizes of 10, 12, 15, 16, or 20 MB
Select CPUs
The supported Intel Xeon E5-4600 series CPUs on the UCS B420 M3 are listed in Table 3.
Supported Configurations
(1) Two-CPU Configuration
■ Choose two identical CPUs from any one of the rows of Table 3. CPUs 1 and 2 will be
populated.
(2) Four-CPU Configuration
■ Choose four identical CPUs from any one of the rows of Table 3.
Notes
■ The system will run at the lowest CPU or DIMM clock speed. For example, when using
1600-MHz DIMMs with an E5-4603 CPU (which can only support up to 1066-MHz DIMMs), the
system will run at the lower speed of 1066 MHz.
■ System speed is also dependent on how many DIMMs are populated per channel.
■ For 2-CPU systems, only 24 DIMM slots are functional (channels A - H). See Table 9 on page
17 for supported adapter combinations in 2-CPU systems.
■ For 4-CPU systems, all 48 DIMM slots are functional.
