Cisco UCS C24 M3 High-Density LFF Rack Server

CONFIGURING the SERVER

■ By default, all DIMMs run at 1.35 V, which yields 1333-MHz memory speeds. To run the

memory DIMMS at 1600 MHz, you need to go into the BIOS or set the policy with UCSM

(service profile) to run in Performance Mode. This forces the DIMMs to operate at 1.5 V and

yields 1600-MHz speeds, provided:

— The DIMMs are 1600-MHz devices

— The CPUs chosen support 1600-MHz operation.

For more information regarding memory, see CPUs and DIMMs, page 47.

NOTE: 32 GB LRDIMMs run at a maximum speed of 1333 MHz for 1 DPC and 2 DPC

even though their specified maximum speed is 1600 MHz.

NOTE: In this server, 4 GB UDIMMs run slower than their specified maximum speed of

1600 MHz. In addition, the following rules apply to UDIMMs:

■ 1 DPC: 1333 MHz is supported at 1.35 V and 1.5 V

■ 2 DPC: 1066 MHz is supported at 1.35 V and 1.5 V
