Cisco UCS B420 M3 Blade Server
CONFIGURING the SERVER
9
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.
