3. HARDWARE SETUP
3.6 Central Processing Unit (CPU)
NOTE: The following pictures are provided for reference purposes only. The ap-
pearance of your retention mechanism and fan may be different from the examples.
Your motherboard provides a Slot 1 connector for a Pentium
®
III processor pack-
aged in a Single Edge Contact Cartridge (SECC2), a Pentium
®
II processor pack-
aged in SECC2/SECC, or a Celeron™ processor packaged in a Single Edge Proces-
sor Package (SEPP). An ASUS S370 CPU card can allow Socket 370 processors to
be used on any ASUS motherboard with the Slot 1 connector (See 7.2 S370 Series
CPU Cards for instructions on using this card).
3.6.2 Heatsinks
The recommended heatsinks (see 3.6.4 Recommended Heatsinks for Slot 1 Proces-
sors) for the boxed Pentium III / II and Celeron processors are those with three-pin
fans that can be connected to the fan connectors on the motherboard.
WARNING! Be sure that there is sufficient air circulation across the processor’s
heatsink by regularly checking that your CPU fan is working. Without sufficient
circulation, the processor could overheat and damage both the processor and the
motherboard. You may install an auxiliary chassis fan, if necessary.

NOTE: The SEPP fan (for Celeron processors) is
similar to SECC2 fan except that the clamping
design is different.
Your motherboard comes preinstalled
with a Universal Retention Mechanism
(URM). The URM supports Pentium III /
II and Celeron processors.
