Choose Proper Parts for Your System 


Before you installing a system with this motherboard, make sure your major system parts meet the 

following basic guidelines and requirements: 

Central Processor Unit (CPU) Considerations 

● Process Type and Package 

D2568 supports Dual-Core Intel® Xeon® Processors 5200 Series as well as Quad-Core Intel® 

Xeon® Processors 5400 Series in FC-LGA6 package for LGA771 socket. 

● Front Side Bus (FSB) 

The processor host bus, or called Front Side Bus (FSB), auto-operates at 1333 MHz. Choose 

Dual-Core Intel® Xeon® Processors 5200 Series or Quad-Core Intel® Xeon® Processors 

5400 Series with 1333 MHz FSB for D2568. 

● Single/Dual Processor System 

D2568 board supports one or two Dual-Core or Quad-Core Intel® Xeon® Processors. 

Single Processor System: 

When only install a single processor on D2568, the processor must be installed in the CPU0 

socket. 

Dual Processor System: 

D2568 supports dual processor configurations only in which both processors operate with the 

same FSB frequency, core frequency, and have the same internal cache sizes. Mixing 

processors operating at different FSB frequency, core frequency, or cache sizes may cause 

system non-operation or damages on processors and/or the motherboard. 

Memory Considerations 

● Memory Type 

D2568 supports up to eight 240-pin 1.8-Volt DDR2-667 ECC FB-DIMM modules. 

● Memory Installation 

D2568 is based on Intel®’s 5400 Seaburg chipset, which supports 144-bit wide quad memory 

channels in memory interleaved scheme. System requires minimum one memory to boot up 

the system. 

For further information see "Installing the Memory" chapter. 



Power Supply Considerations 

● Power connectors 

D2568 is powered by a split plane PSU with six +12V-rails and 1000W continuous power. One rail is 

for each processor, one for systemboard and three for peripherals (e.g. HHDs, add. 6-pin graphics 

connector). There are three power connectors on this motherboard as listed below.

+12V_CPU1 GND 

24-pin baseboard power connector 8-pin CPU power connector 

(split CPU power planes) 

+12 GND 

10-pin additional baseboard power connector 

By following SSI EEB v3.51 specifications, D2568 is designed with two separate voltage 

regulator circuits to provide the power for both onboard processors in separate power rail. 

Using a power supply with a combined CPU power plane from the CPU power connector is not 

allowed and may cause the system to fail to power up or damage to the power supply.

Installing the Memory 


Before attempting to install any memory, make sure that the memory you have is compatible with the 

motherboard as well as the processor. The D2568 board supports up to eight 240-pin 1.8-Volt 

DDR2-667 ECC FB-DIMM modules. 

Here are a few key points to note before installing memory into your D2568: 

● 256MB, 512MB, 1GB, 2GB, 4GB and 8GB ECC FB-DIMM memory modules are supported 

● All installed memory will be automatically detected - no need to set any jumpers 

● The D2568 supports up to 64 GB of memory 

● Memory modules are organized in pairs. Both modules of a pair must be of same type and 

density, otherwise the memory may not be detected correctly or system instability may be 

caused. 

● For debug mode, one FB-DIMM module can be used plugged into DIMM1 socket 

Please refer to the following table memory configuration:

8 X X X X X X X X 

socket colour black white black white black white black white 

All DIMMS must be the same type and size DIMM. It is also recommended that you 

use all DIMMS from the same manufacturer for improved reliability. 



Memory Installation Procedure 

When installing memory modules, make sure the modules align properly with the memory socket. 

There should be keys (small indents) on your memory modules that fit according to the keys in the 

memory socket. DDR modules and sockets have only one key, which is slightly near the center of 

the module/socket. The method of installing memory modules is detailed in the following diagrams. 

Installing a memory module 

2 

► Push the holders on each side of the memory slot outwards. 

► Insert the memory module into the location (1). 

► At the same time flip the lateral holders upwards until the memory module snaps in place (2).

Removing a memory module 

1 

► Push the clips on the right and left of the memory slot outward (1). 

► Pull the memory module out of the memory slot (2). 

i 

!

When installing memory, a module may require a considerable amount of force to seat 

properly, although this is very rare. To avoid bending and damaging your motherboard, 

place it on its anti-static bag and onto a flat surface, and then proceed with memory 

installation. 

You must unplug the power connector to the motherboard before performing system 

hardware changes, to avoid damaging the board or expansion device. 



Installing the Processor and Heatsink 

Installing the processor 

! 

The processor socket ist covered with a protective cap to protect the spring contacts 

In a warranty case the mainboard can only be taken back by Fujitsu Siemens Computers 

with the protective cap secured! 

Never touch the underside of the processor. Even minor soiling such as grease from the 

skin can impair the processor's operation or destroy the processor. 

Place the processor in the socket with extreme care, as the spring contacts of the socket 

are very delicate and must not be bent. 

► Remove the heat sink. 

► Remove the old processor (3) from the socket.

Hold the new processor between your thumb and 

index finger and insert it into the socket (b) so that 

the marking of the processor is aligned with the 

marking on the socket (a). 

► Fold down the frame (1). 

► Press the lever downward (2) until it is hooked 

in again. 

► Remove the protective cap (3) and keep it. 



Mounting heat sink 

i 

Use only the heat sink supplied with your system! 

Be sure to use heat conducting material between the processor and the heat sink. If a heat 

conducting pad (rubber-like foil) is already applied to the heat sink, then use it. Otherwise you must 

apply a very thin layer of heat conducting paste. 

Heat conducting pads can only be used once. If you remove the heat sink, you must clean it and 

apply new heat conducting paste before you remount it.

► Depending on the configuration variant, you 

must pull a protective foil off the heat sink or 

coat the heat sink with heat conducting 

paste before fitting it. 

► Secure the heat sink - depending on the 

model - with four screws or push it into the 

mounts. 


Installing Add-In Cards 


Before installing add-in cards, please check if they are fully compatible with your motherboard. 

PCI-E X16 (x16) 

PCI-E X8 (x8) 

PCI-E X16 (x16) 

PCI-X 133 

PCI-X 133 

PCI32 

Simply find the appropriate slot for your add-in card and insert the card firmly. Do not force any addin 

cards (or anything else) into any slots if they won’t seat in place. It’s better to try another slot or 

return the faulty card rather than damaging both the motherboard and the add-in card. 

i 

! 

It’s a good practice to install add-in cards in a staggered manner, rather than directly 

adjacent to each other. This allows air to more easily circulate within the chassis, providing 

improved cooling for all installed devices. 

You must unplug the power connector to the motherboard before performing system 

hardware changes, to avoid damaging the board or expansion device. 



Connecting External Devices 

Connecting external devices to the motherboard is an easy task. The standard devices you should 

expect to plug into the motherboard are keyboards, mouse, and printer cables. The following 

diagram will detail the ATX port stack for the following board:

While the ports have been created to accept connectors in only one direction, make sure 

to be careful when inserting connectors. At times, attaching connectors in the incorrect 

orientation can damage, bend and or break the pins. 


Installing the Power Supply 

There are three power connectors on this motherboard: 

● 24-pin P1 baseboard power connector (according SSI 3.51 spec) 

● 8-pin processor power connector (according SSI 3.51 spec) 

● 10-pin additional baseboard power connector (5xGND, 5x+12V) 


The used power supply is a split plane PSU with six +12V-rails and delivers 1000W continuous 

power. One rail is for each processor, one for systemboard and three for peripherals (e.g. HHDs, 

add. 6-pin graphics connector). 

The power supply has: 

● one 24-pin molex-type connector for the baseboard (P1) 

● one 8-pin molex-type connector for the processor power (P17) 

● one 10-pin molex-type additional baseboard power connector (P18) – two yellow wires and two 

black wires (only for use with this workstation) 

● four 6-pin connectors for graphic adapters (P12, P13, P15, P16) 

● two 8-pin connectors for graphic adapters (P11, P14) 

● several HDD-, floppy- and SATA power connectors 

Two onboard switching voltage regulators that are sourced by separate +12V power rails provide 

each CPU’s power. This +12V CPU power source is from the onboard 8-pin square connector. The 

+12V power on the 24-pin baseboard power connector and on the 10-pin additional baseboard 

power connector is for system board and separated from CPU +12V regulator power source. 

Therefore, the CPU will not be powered if you do not connect the 8-pin square 12V power 

connector. 

! 

You must unplug the power supply before plugging in the power cables to motherboard 

connectors. 



Replacing lithium battery 

In order to permanently save the system information, a lithium battery is installed to provide the 

CMOS-memory with a current. A corresponding error message notifies the user when the charge is 

too low or the battery is empty. The lithium battery must then be replaced. 

! 

Incorrect replacement of the lithium battery may lead to a risk of explosion! 

The lithium battery may be replaced only with an identical battery or with a type 

recommended by the manufacturer. 

Do not throw lithium batteries into the household waste. They must be disposed of in 

accordance with local regulations concerning special waste. 

Make sure that you insert the battery the right way round. The plus pole must be on the 

top! 

The lithium battery holder exists in different designs that function in the same way.

BIOS update 

When should a BIOS update be carried out? 


Fujitsu Siemens Computers makes new BIOS versions available to ensure compatibility to new 

operating systems, new software or new hardware. In addition, new BIOS functions can also be 

integrated. 

A BIOS update should always also be carried out when a problem exists that cannot be solved with 

new drivers or new software. 

How does a BIOS update work? 

1. BIOS update under DOS with BIOS Flash Update bootable floppy disk 

► Download the update file from our website to your PC. 

► Insert an empty floppy disk (1.44 MB). 

► Run the update file (e.g. 2568102.EXE). 

► A bootable update floppy disk is created. Leave this floppy disk in the drive. 

► Restart the PC. 

► Follow the instructions on screen. 

2. BIOS update under Windows with DeskFlash utility 

A BIOS update can also be carried out directly under Windows with the DeskFlash utility. DeskFlash 

is contained on the “Drivers & Utilites” CD (under DeskUpdate). 



BIOS Recovery 

i 

All BIOS settings are reset to the default values. 

► Opening the casing as described in the operating manual. 

► Close the jumper RCV (JP23). 

► Close the casing as described in the operating manual. 

► Insert a BIOS Recovery Disk and start the PC. 

► Note the signals issued from the buzzer or loudspeaker. You have successfully restored the 

BIOS if you hear continuously fast repeated beeps.
