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

non6Hoptimal. The system clocks down the performance to the slowest speed

in the DIMM set for the channel.

Figure 1-1. Internal USB Connector Location

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.

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

conform to the following maximum dimensions: 11.68mm thick (0.46") x 24.89mm

width (0.98") x 66.8mm length (2.63").

Support for 8-GB Memory Modules –

PowerEdge 1950 III Systems

PowerEdge 1950 III systems have added support for the following approved

8-GB memory configurations:

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

• 48 GB — 4 x 8-GB quad-rank and 4 x 4-GB dual-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 ships with your system.

• If the front of your system chassis is labeled with a "II," your system is

upgradeable to the 5100 series of dual-core Intel Xeon processors and

the 5300 series of quad-core Intel Xeon processors.

• If the front of your system chassis is labeled with a "III," your system is

upgradeable to the 5100 and 5200 series of dual-core Intel Xeon processors

and the 5300 and 5400 series of quad-core Intel Xeon processors.

10 Information Update

System Board Replacement – Safeguarding

Encrypted Data

On PowerEdge 1950 III systems using Windows Server®2008, you can use

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

of the hard drive.

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 1950 III system and

the probable cause and corrective action when the message appears.

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
