1.5 Processor
✏ NOTE
Refer to Thermal Considerations (Section 2.12, page 90) for important information when using an
Intel Pentium 4 processor operating above 2.80 GHz with this Intel desktop board.
The board is designed to support the following:
• Intel Pentium 4 processors in an mPGA478 processor socket with a 400/533/800 MHz system
bus
• Intel Celeron processors in an mPGA478 processor socket with a 400 MHz system bus
See the Intel web site listed below for the most up-to-date list of supported processors.
For information about…Refer to:
Supported processors for the D865GRH board http://www.intel.com/design/motherbd/rh/rh_proc.htm
CAUTION
Use only the processors listed on web site above. Use of unsupported processors can damage the
board, the processor, and the power supply.
# INTEGRATOR’S NOTES
• Use only ATX12V-, SFX12V-, or TFX12V-compliant power supplies with the Desktop Board
D865GRH. ATX12V, SFX12V, and TFX12V 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, SFX12V, and TFX12V power supplies to the corresponding connectors
on the desktop board, 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.
• Refer to Table 4 on page 21 for a list of supported system bus frequency and memory speed
combinations.
For information about Refer to
Power supply connectors Section 2.8.2.3, page 76
