Chapter 1: Product introduction |
1.6Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for the Intel¨ Pentium¨ 4 processor in the 775-land package.
¥Your boxed Intel¨ Pentium¨ 4 LGA775 processor package should
come with installation instructions for the CPU, fan and heatsink assembly. 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 pins are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket pins/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 pins resulting from incorrect CPU installation/removal, or misplacement/ loss/incorrect removal of the PnP cap.
1.6.1Installling the CPU
To install a CPU:
1.Locate the CPU socket on the motherboard.

1.6.2Installling the CPU heatsink and fan
The Intel¨ Pentium¨ 4 LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.
¥ Install the motherboard to the chassis before you install the CPU fan and heatsink assembly
¥When you buy a boxed Intel¨ Pentium¨ 4 processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, make sure that you use only Intel¨-certified multi-directional heatsink and fan.
¥Your Intel¨ Pentium¨ 4 LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.
If you purchased a separate CPU heatsink and fan assembly, make sure that a Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly.
To install the CPU heatsink and fan:
1.Place the heatsink on top of the installed CPU, making sure that the four fasteners match the holes on the motherboard.

1.7System memory
1.7.1Overview
The motherboard comes with four 240-pin Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket.
The following figure illustrates the location of the sockets:

1.7.2Memory Configurations
You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR2 DIMMs into the DIMM sockets using the memory configurations in this section.
¥For dual-channel configuration, the total size of memory module(s) installed per channel must be the same (DIMM_A1+DIMM_B1=DIMM_A2+DIMM_B2)
¥Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. Refer to the DDR2-533 Qualified Vendors List on the next page for details.
¥Due to chipset resource allocation, the system may detect less than 4 GB of system memory when you installed four 1 GB DDR2 memory modules.
¥Due to chipset limitation, DIMM modules with 128 Mb memory chips or double-sided x16 memory chips are not supported in this motherboard.
