Intel Xeon 5600 Series Processors—

Information Update

Important Information

• Your system requires a BIOS and iDRAC firmware upgrade to support Intel

Xeon 5600 series processor (less than 130 W). You can download the BIOS and

iDRAC firmware for the Intel Xeon 5600 series processor at

support.dell.com

NOTE: A BIOS and iDRAC firmware update only supports a limited feature set of

the Intel Xeon 5600 series processor.

• The following new Dell PowerEdge systems marked with the Roman Numeral

II on the chassis support the complete feature set of Intel Xeon 5600 series

processors:

– R410

– R510

– R610

– R710

– T410

– T610

– T710

– M610

– M710

NOTE: The PowerEdge R410, T410, and R510 systems do not support 130 W

Intel Xeon 5600 series processors.

NOTE: The modular systems, PowerEdge M610 and M710, support the 130 W

Intel Xeon X5680 only in the 130 W processor category.

NOTE: The PowerEdge R610 and M710 systems need specific heat sinks to

support the 130 W Intel Xeon 5600 series processors.

• Mixing of Intel Xeon 5500 and 5600 series processors is not supported.

• Systems with the Intel Xeon 5600 series processors support memory sparing.

Low Voltage Memory Modules (DDR3L DIMMs)

Intel Xeon 5600 series processors

support DDR3L DIMMs enabling a lower

operating voltage (1.35 V) that ensures memory power savings up to 20% per

DIMM. DDR3L memory is backward-compatible to Intel Xeon 5500 series and

operates at standard voltage (1.5 V) without any limitations.

Operating the system memory at a lower voltage may cause restrictions to

additional frequency and memory population capabilities. For example,

populating three memory modules per channel is not supported at 1.35 V.

Systems with

1.35 V DDR3L memory

operates the memory modules at 1.5 V

if any of the following conditions exist:

• Intel Xeon 5500 series processors

• Two 1333 MHz DIMMs per channel

• A combination of both standard and low voltage memory modules

For information on the memory configuration guidelines, see your system’s

Hardware Owner’s Manual at support.dell.com/manuals.

NOTE: BIOS setup options allow the user to control frequency and voltage

configuration within allowable limits.

New POST Messages

The following are the new POST messages for the Intel Xeon 5600 series

processors.

Enabling Dell BIOS Intelligent Turbo Mode

The Dell BIOS Intelligent Turbo Mode feature allows the operating system to set

the processor performance in the turbo mode. Based on the processor utilization,

this feature delays the processor turbo mode initiation for better power

management. When the turbo mode is enabled in the Processor Settings screen

of the system setup, the feature can be enabled or disabled using the following

BIOS setup options:

NOTE: The Dell BIOS Intelligent Turbo Mode is disabled when the turbo mode is

disabled in the processor system setup screen.

Message Description

System Memory Size:
