Chapter 2: Choose Proper Parts For Your System
Before you installa system with this motherboard, make sure your major system parts meet the
following basic guidelines and requirements:
2.1 –Central Processor Unit (CPU) Considerations
§Process Type and Package
Thunder i7525 (S2676) board supports Intel Xeonprocessors in 604-pin Pin Grid
Array package.
§Front Side Bus (FSB)
The processor host bus, or called Front Side Bus (FSB), always operates at 800 MHz.
Choose Intel Xeon800 MHz FSB processors for Thunder i7525 (S2676) board.
The system will not operate with 400MHz FSB or 533MHz FSB Intel XeonCPUs.
§Single/Dual Processor System
The S2676 will only support a dual CPU configuration where BOTH CPUs have the
same FSB, Core Frequency and internal cache sizes. Using CPUs that do not follow
these guidelines can/would result in damage to the CPUs or the motherboard.
Single Processor System:
When installing only a single CPU, that CPU must be installed on CPU1 socket to
operatecorrectly.
Dual Processor System:
Thunder i7525 (S2676) board 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.
2.2 –Memory Considerations
§MemoryType
The S2676 motherboard supports up to eight 240-pin, 1.8 volt DDR2-400 Reg/ECC
modules. The 8 slots support 256MB, 512MB, 1GB, 2GB and 4*GB memory sticks up
to 32*GB the maximum in total. (*Not validated at the time of release)
DDR-I or Unbuffered DDR memory modules are not supported by Thunder i7525
(S2676) design.
Visit Tyan’s web site for the memory recommendation list.
§Memory Installation
The Thunder i7525 is based on Intel’s e7525 Tumwater chipset which supports a 144-
bit wide dual memory channel in an interleaved scheme. The motherboard requires a
minimum of 2 memory modules installed in order to boot/POST. You must install these
2 memory modules starting in DIMM slots 1 and 2. Do not mix and match different sizes,
brands or speeds for the best performance and stability possible.

Thunder i7525 (S2676)

2.3 –Chassis/Enclosure Considerations
§Motherboardsize
Thunder i7525 (S2676) board is in the board size of12” (W) x13” (L).
§Motherboard and CPU Heat-sink Mounting Holes
There are six motherboard-mounting holes and eight CPU heat-sink mounting holes on
Thunder i7525 (S2676) board design. The motherboard and CPU mounting hole
locations follow SSI EEB v3.51 (AServer System Infrastructure specification for Entry
Pedestal Servers and Workstations) specifications. Ensure that the SSI-EEB chassis
you purchase is designed to accommodate the new Nacona heat sink mounting
process.
NOTE: There are many SSI-EEB chassis, but not all will accommodate the Nacona
design for the direct heat sink attachment to thechassis.Check with your vendor to
make sure thechassis supports the design.
Thunder i7525 (S2676) supports Intel’s CEK (Common Enabling Kit) for securing Intel’s
Xeon800 MHz FSB processors in the chassis. Two CEK springs for the dual
processors are pre-assembled with the motherboard or enclosed in the motherboard
accessory package. The CPU heat-sinks must be mounted down to the chassis base
panwithstand-offs. Any additional chassis standoffs, besides the 6 motherboard-
mounting holes and 8 CPU heat-sink mounting holes, should be removed to preventing
from short-circuit or motherboard damage.
§Others
As a system integrator, the air-flow/thermal, EMI/EMC, shock/vibration, and system
packing should be also considered for choosing a proper enclosure.
2.4 –Power Supply Considerations
§Power connectors
Thunder i7525 (S2676) board supports EPS/12V power supply unit (PSU) with three
power connectors listed below.

§Split processor power planes
Thunder i7525 (S2676) board supports dual Intel’s 800 MHz FSB Xeonprocessors,
which could reach up to 140 Watts per processor. (Check Intel’s web for the processor
specifications.) By following SSI EEB v3.51 specifications, the Thunder i7525 (S2676)
is designed with two separate voltage regulator circuits to provide the power for both
onboard processors in separate power rails. Using a power supply with a combined
CPU power plane from the CPU power connector is not allowed and may causethe
system to fail to power up or damage to the power supply.

Chapter 3: Board Installation
How to install our products right….the first time!
The first thing you should do read this user’s manual. It contains important information that will
make configuration and setup much easier. Here are some precautions you should take when
installing your motherboard:
(1) Ground yourself properly before removing your motherboard from the antistatic bag.
Unplug the power from your computer power supply and then touch a safely grounded
object to release static charge (i.e. power supply case). For the safest conditions,
TYANrecommends wearing a static safety wrist strap.
(2) Inspect the mounting holespattern of the Thunder i7525 (S2676) to match your chassis
standoff locations and remove the additional standoffs.
(3) Hold the motherboard by its edges and do not touch the bottom of the board, or flex the
board in any way.
(4) Avoid touching the motherboard components, IC chips, connectors, memory modules
and leads.
(5) Place the motherboard on a grounded antistatic surface or on the antistatic bag that the
board was shipped in.
(6) Inspect the board for damage.
(7) Check the jumper settings and connector locations as described in next sections.
In last sections of this chapter, we will cover the details on how to install your motherboard into
your chassis, as well as installing the processor, memory, disk drives andcables.
NOTE: Do not apply power to the board if it has been damaged.

3.3 –Mounting the Motherboard
Before installing your motherboard, make sure your chassis has the necessary motherboard
support studs installed. These studs are usually metal and are in gold or silver color. Usually, the
chassis manufacturer will pre-install the support studs. Remove the unused or additional studs,
which may scratch the motherboard or cause short-circuit with the components on the bottom
side. If you’re unsure of stud placement, simply lay the motherboard inside the chassis and align
the screw holes of the motherboard to the studs inside the case. If there are any studs missing,
you will know right away since the motherboard will not be able to be securely installed. Some
chassis’ include plastic studs instead of metal. Although the plastic studs are usable, TYAN
recommends using metal studs with screws that will fasten the motherboard more securely in
place.
3.4 –Installing the Processor and Heatsink
Your Thunder i7525 (S2676) supports the latest processor technologies from Intel. Check the
following page on TYAN’s website for latest processor support:
http://www.tyan.com
The following diagrams will detail how to install your processor:
The diagram is provided as a visual guide to help you install socket processors and may not be an
exact representation of the processors you have.
1. Lift the lever on the socket until it is approximately 90o or as far back as possible to the
socket.
2. Align the processor with the socket. There are keyed pins underneath the processor to
ensure that the processor’s installed correctly.
3. Seat the processor firmly into the socket by gently pressing down until the processor
sits flush with the socket.
4. Place the socket lever back down until it locks into place.
5. Your processor is installed.
Take care when installing the processor as it has very fragile connector pins below the
processorthat can bend and breakif inserted improperly.
Heatsink Installation
After you are done installing the processor, you should proceed to installing the heatsink.
Heatsink will ensure that the processor not overheat and continue to operate at maximum

Thunder i7525 (S2676)
http://www.tyan.com
17
performance for as long as you own them. Anoverheated processor is dangerous to the health of
the motherboard.
DCA (Direct Chassis Attach) is required to install the Intel Xeon processor on the S2676
motherboard. The processor heat sinks need to be Intel’s CEK (Common Enabling Kit) compliant
to attach properly. Each processor heat sink needs to be mounted directly to the chassis via the 4
mounting studs. If your chassis does not have the holes to attach these heat sinks directly, then it
is not the correct version of the SSI-EEB v3.5chassis that supports Intel’s latest design.
-MemoryType:
The S2676 motherboard supports Reg/ECC DDR2-400 memory modules and requires a
minimum of 2 DIMMs to boot/POST the system. Unbuffered or DDR memory isNOT
supported with this motherboard.
