Chapter 2: 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:

2.1 - Central Processor Unit (CPU) Considerations

● Process Type and Package
Thunder i7525 S2676 board supports Intel Xeon
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 be operational when installing Intel Xeon
processors.
● Single/Dual Processor System
Thunder i7525 S2676 board supports single or dual Intel Xeon
Single Processor System:
When only install a single processor on Thunder i7525 S2676 board, the processor must be
installed on the CPU1 ZIF (Zero-Insertion-Force) socket.
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.
