2.3 Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed for

the Intel

Pentium

D, Intel

Pentium

4 and Intel

Celeron

processors in

the 775-land package.

This motherboard supports the Intel

Pentium

Processor Extreme Edition,

the latest CPU with embedded dual physical cores and Hyper-Threading

technology, making four CPU threads possible. Refer to the table below for

the operating system support status.

•

Install a chassis fan with at least a speed of 2400 rpm and 8 CFM

turnrate when using a dual-core CPU to ensure system stability.

Overheating can permanently damage the system and/or CPU.

• Install an additional chassis fan to ensure better air flow when

overclocking.

• Upon purchase of the motherboard, make sure that the PnP cap is

on the socket and the socket contacts are not bent. Contact your

retailer immediately if the PnP cap is missing, or if you see any

damage to the PnP cap/socket contacts/motherboard components.

ASUS will shoulder the cost of repair only if the damage is shipment/

transit-related.

•

Keep the cap after installing the motherboard. ASUS will process

Return Merchandise Authorization (RMA) requests only if the

motherboard comes with the cap on the LGA775 socket.

• The product warranty does not cover damage to the socket

contacts resulting from incorrect CPU installation/removal, or

misplacement/loss/incorrect removal of the PnP cap.
