1.6 Processor
CAUTION
Use only the processors listed below. Use of unsupported processors can damage the board, the
processor, and the power supply. See Intel’s World Wide Web site for the most up-to-date list of
supported processors for this board.
The board provides an mPGA478 processor socket. Table 4 lists the supported processors. All
supported onboard memory can be cached. See the processor’s data sheet for cachability limits.

 INTEGRATOR’S NOTES
• Use only ATX12V- or SFX12V-compliant power supplies with the board. ATX12V and
SFX12V power supplies have an additional power lead that provides required supplemental
power for the processor. Always connect the 20-pin and 4-pin leads of ATX12V and SFX12V
power supplies to the corresponding connectors, otherwise the board will not boot.
• Do not use a standard ATX power supply. The board will not boot with a standard ATX
power supply.
For information about Refer to
Processor support Section 1.3, page 16
Power supply connectors Section 2.8.2.2, page 50
