Non-Optimal Memory Configurations

The POST may halt when a non-optimal memory configuration is detected

and the following message is displayed:

Non-Optimal Memory Configuration

Press F1 to continue or F2 for Setup

NOTE: Mixing DIMMs of different speeds renders the memory configuration

non-optimal. The system clocks down the performance to the slowest speed

in the DIMM set for the channel.

PowerEdge 2950 III – New System Features

New Performance Features

• Two dual-core or quad-core Intel

Xeon

5400 Series and 5300 Series

processors.

• 8-GB memory module support.

New High-Efficiency Power Supply and Power Monitoring Features

• Higher system efficiency on power conversion across workloads.

• Baseboard Management Control (BMC) power monitoring monitors

current, voltage, and power utilization in the system.

6Information Update

New I/O and Storage Features

• Optional Intel quad-port Gigabit Ethernet NIC, capable of supporting

10-Mbps, 100-Mbps, and 1000-Mbps data rates, and iSCSI remote boot.

• Support for 10-Gb Ethernet cards.

New Security Features

• Trusted Program Module (TPM) support for improved security.

• Optional support for iSCSI boot.

Optional Internal USB Memory Key

The system provides an internal USB connector located on the sideplane

board for use with a USB flash memory key. The USB memory key can be

used as a boot device, security key, or mass storage device. To use the internal

USB connector, the Internal USB Port option must be enabled in the

Integrated Devices screen of the System Setup program. See "Integrated

Devices Screen" on page 20.

To boot from the USB memory key, you must configure the USB memory

key with a boot image and then specify the USB memory key in the boot

sequence in the System Setup program. See “

Using the System Setup

Program” in the

Hardware Owner’s Manual

. For information on creating

a bootable file on the USB memory key, see the user documentation that

accompanied the USB memory key.

NOTE: USB keys that contain multiple LUNs (Logical Unit Numbers) must

be formatted using the format utility provided by the key manufacturer.

CAUTION: To avoid interference with components inside the system, the USB key

must conform to the following maximum dimensions: 11mm thick (0.43") x 23.2mm

width (0.91") x 67mm length (2.64").

Support for 8-GB Memory Modules –

PowerEdge 2950 III Systems

PowerEdge 2950 III systems have added support for the following approved

8-GB memory configurations:

•64 GB — 8 x 8-GB quad-rank memory modules

If 64 GB of memory is installed, the system only recognizes and displays

63.75 GB during POST.

NOTE: Prior to upgrading your system, verify that the latest system BIOS version is on

your system. Loading the latest BIOS version ensures that your system is fully supported.

NOTE: Some operating systems cannot support more than 4 GB of physical memory.

For more information on memory support requirements and restrictions, refer to the operating

system documentation that was shipped with your system.

System Board Replacement –

Safeguarding Encrypted Data

On PowerEdge 2950 III systems using Windows Server®2008, you can use

encryption programs, such as the BitLocker utility, to secure the contents

of the hard drive.

10 Information Update

If you are using the TPM with an encryption application, you are prompted

to create a recovery key during system setup. Be sure to store this recovery key.

If you replace the system board, you must supply the recovery key when you

restart your system before you can access the encrypted files on your hard

drive(s).

System Message Update

Table 1-1 lists new system messages for the PowerEdge 2950 III system and

the probable cause and corrective action when the message appears. System

messages appear on the screen to notify you of a possible problem with the

system.

WARNING: Only trained service technicians are authorized to remove the system

cover and access any of the components inside the system. See your Product

Information Guide for complete information about safety precautions, working

inside the computer, and protecting against electrostatic discharge.

Alert! Node

Interleaving

disabled! Memory

configuration does

not support Node

Interleaving.

The memory configuration

does not support node

interleaving, or the

configuration has changed

(for example, a failed

DIMM) so that node

interleaving cannot be

supported. The system

runs but with reduced

functionality.

Ensure that the memory

modules are installed in a

configuration that supports

node interleaving. Check

other system messages

for additional information

for possible causes.

For memory configuration
