Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for
the Intel® Pentium® 4 and Conroe processor in the 775-land package.
•
Your boxed Intel® Pentium® 4 processor package should
come with installation instructions for the CPU, heatsink, and the
retention mechanism. If the instructions in this section do not match
the CPU documentation, follow the latter.
•
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.

Memory configurations
You can install 256 MB, 512 MB, and 1 GB DDR2 SDRAM DIMMs into the
DIMM sockets using the memory configurations in this section.
•
Installing DDR2 DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations on the next page.
•
•
Install only identical (the same type and size) DDR2 DIMM pairs
using the recommended configurations.
Make sure that the memory frequency matches the CPU FSB (Front
Side Bus). Refer to the Memory frequency/CPU FSB synchronization
table on the next page.
•
•
This motherboard does not support double-sided 16-bit DDR DIMMs.

Jumpers
Clear RTC RAM (3-pin CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard
button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear
CMOS). Keep the cap on pins 1-2 for about 5~10 seconds, then
move the cap back to pins 2-3.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
