Cisco UCS B420 M3 Blade Server

CONFIGURING the SERVER
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 10 on page
19 for supported adapter combinations in 2-CPU systems.
■ For 4-CPU systems, all 48 DIMM slots are functional.
