Information Update 3

Important Information

The following new Dell PowerEdge systems support the Intel Xeon processor

E7-2800/4800/8800 product family:

• PowerEdge R810 II

• PowerEdge R910 II

• PowerEdge M910 II

These systems are marked with the Roman numeral "II" on the system

identification panel (PowerEdge R910 II and R810 II) or on the blade handle

(PowerEdge M910 II). See Figure 1.

NOTE: PowerEdge R810, R910, and M910 systems without the Roman numeral “II”

support Intel Xeon processor E7-2800/4800/8800 product family with a limited

feature set.

Information Update 5

Table 2 provides the number and type of processors supported on

PowerEdge

R910, R810, and M910 systems

Table 2. Intel Xeon Processor E7-2800/4800/8800 Product Family Supported on

PowerEdge R910, R810, and M910 Systems

• Mixing of Intel Xeon processor 7500 series and E7-2800/4800/8800

product family is not supported.

• Operating systems with a maximum of 64 cores do not support the

maximum amount of logical cores achievable with four 10-core processors

and logical processors enabled (80 cores). Check with your operating

system vendor for more information.

NOTE: To work around this issue, disable Logical Processors in the Processor

Settings screen of system setup program, or reduce the Number of Cores per

Processor in the Processor Settings screen of system setup program.

* PowerEdge R810 systems support 4 x 130 W Intel Xeon processor E7-4800/8800

product family only if the system has two power supply units. PowerEdge R810

systems do not support 4 x130 W Intel Xeon processor 7500 series.

6Information Update

• If your system does not have the Roman numeral "II" label, it requires

CPLD, BIOS, and iDRAC firmware upgrade to support Intel Xeon

processor E7-2800/4800/8800 product family. You can download the

CPLD, BIOS, and iDRAC firmware at

support.dell.com

NOTE: Update the BIOS with 7500 series installed before replacing with Intel Xeon

processor E7-2800/4800/8800 product family.

Low Voltage Memory Modules (DDR3L DIMMs)

DDR3L RDIMMs enable a lower operating voltage (1.35 V) and save up to 20

percent of memory power per RDIMM. The following are required to support

DDR3L RDIMMs at 1.35 V:

• Intel Xeon processor E7-2800/4800/8800 product family

• Memory riser (PowerEdge R910 II) marked with the Roman Numeral "II"

or system board (PowerEdge R810/M910 II) with Intel 7510 scalable

memory buffer.

Supported DDR3L are 2 GB x8, 4 GB x8, 8 GB x8, and 16 GB x4 DRAM

RDIMMs.

NOTE: RDIMMs rated at 1333 MT/s operate at maximum of 1066 MT/s.

• PowerEdge R810 supports four 130 W Intel Xeon processor E7-4800/8800

product family only with DDR3L at 1.35 V.

• PowerEdge R910 memory riser board marked with the Roman numeral "II"

supports DDR3L RDIMMs.

• PowerEdge R910 does not support mixing memory risers with and without

the Roman numeral "II".

• 32 GB x4, 4 Gb DRAM, DDR3L RDIMMs are supported on PowerEdge

R910 with Intel Xeon processor E7-2800/4800/8800 product family and

memory riser board marked with the Roman numeral "II".

Information Update 7

Systems with 1.35 V DDR3L memory modules operate at 1.5 V if any of the

following conditions exist:

• Intel Xeon processor 7500 series.

• A combination of standard and low voltage memory modules on system

board or memory risers.

• Memory riser (PowerEdge R910) not marked with the Roman Numeral "II"

or system board (PowerEdge R810/M910) with Intel 7500 scalable memory

buffer.

DDR3L memory is backward compatible with Intel Xeon processor 7500

series and operates at standard voltage (1.5 V).

System Setup Updates

Memory Settings Screen

Option Description

System Memory

Voltage

Displays the current operating voltage of the system

memory.

Memory Operating

Voltage

(Auto default)

Sets the system memory voltage selection. When set to

Auto, the system automatically sets the system voltage to

the optimal setting based upon the DIMM capability and

the installed DIMM population. This also enables setting

the system memory voltage to a higher value (1.5 V) if the

DIMMs support multiple voltages and have been auto set

to a lower voltage of 1.35 V.

Redundant Memory

(Disabled default)

Sets the type of memory operation if a valid memory

configuration is installed. When set to Mirror mode,

memory mirroring is enabled, while the Spare mode allows

memory sparing. The DDDC mode option enables double

device data correction.

NOTE: A valid DDDC configuration requires all installed

DIMMs with x4 DRAMs.

10 Information Update

Enabling Dell BIOS Intelligent Turbo Mode

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

set the processor performance to 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, this 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

set to Disabled in the Processor Settings screen.
