Chapter 2: Hardware information
2.4.1 Overview
The motherboard comes with a surface mount 940-pin Zero Insertion
Force (ZIF) socket. The socket is designed for the new AMD Opteron™
Processor in the 940-pin lidded ceramic micro PGA package. The AMD
Opteron™ processor is a 64-bit server and workstation processor based
on the industry-standard x86 instruction set architecture that can run x86-
based 32 and 64-bit applications. Integrated with the processor is a low-
latency high-bandwidth memory controller and a highly scalable
HyperTransport™ technology-based system bus. Also, the processor
includes Error Correcting Code (ECC) protection for L1 and L2 cache data
and DRAM ECC protection with chipkill.
Additionally, the 128-bit-wide data paths of the AMD Opteron™ processor
run applications faster than traditional processors with only 32 or 64-bit
wide data paths. Current 32-bit processors have a 4 gigabyte memory
addressing cap; the AMD Opteron™ has a 40-bit physical and 48-bit
virtual addressing cap that enable systems to address up to 1 terabyte of
physical memory space and 256 terabytes of virtual memory.
Note in the illustration that the CPU
has a chamfer in one corner. This
mark indicates the processor Pin A1
that should match a specic corner of
the CPU socket.

2.5 System memory
2.5.1 Overview
The motherboard comes with four Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) sockets. These sockets support up to 8GB
system memory using 184-pin PC2700/PC2100/PC1600 ECC DDR
registered DIMMs and allow up to 5.33 GB/s data transfer rate.
The following gure illustrates the location of the DDR DIMM sockets.
Notes on DDR technology
The DDR SDRAM technology evolved from the mainstream PC66, PC100,
PC133 memory known as Single Data Rate (SDR) SDRAM. DDR memory
however, has the ability to perform two data operations in one clock cycle,
thus providing twice the throughput of SDR memory.
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.
Therefore, a DDR DIMM is not backward compatible with SDR, and should
be installed only in a socket specially designed for DDR DIMMs.

may cause memory sizing error or system boot failure. Use any of
the recommended congurations in Table 1.
2. In Dual-channel congurations, install only identical (the same type
and size) DDR DIMM pairs for each channel.
3. Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. See list of Qualied Vendors List on page
2-13.
4. When all four sockets are populated with 1GB DIMMs (total 4GB),
the system may detect only 3+GB (a little less than 4GB) due to
the Northbridge resource allocation.

4.1.4 Using ASUS EZ Flash to update the BIOS
The ASUS EZ Flash feature allows you to easily update the BIOS without
having to go through the long process of booting from a diskette and using
a DOS-based utility. The EZ Flash is built-in the BIOS rmware so it is
accessible by simply pressing <Alt> + <F2> during the Power-On Self
Tests (POST).
To update the BIOS using ASUS EZ Flash:

le for your motherboard. Save the BIOS le to a oppy disk.

following.
4. Insert the oppy disk that contains the BIOS le. If all the necessary
les are found in the oppy disk, EZ Flash performs the BIOS update
process and automatically reboots the system when done.
