2-7 2.3.1 Installing the CPU To install a CPU: 1. Locate the CPU socket on the motherboard. Make sure that the socket lever is lifted up to a 90º angle; otherwise, the CPU will not fit in completely. 2. Unlock the socket by pressing the lever sideways, then lift it up to a 90º angle. 2.3 Central Processing Unit (CPU) The motherboard comes with a 940-pin AM2 socket designed for the AMD Athlon™ 64 X2/Athlon™ 64 FX/Athlon™ 64/Sempron™ processor. Socket lever The AM2 socket has a different pinout from the 939-pin socket designed for the AMD Opteron™ processor. Make sure you use a CPU is designed for the AM2 socket. The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU! M2N32 WS PRO ® M2N32 WS PRO CPU Socket AM2

3. Position the CPU above the socket such that the CPU corner with the gold triangle matches the socket corner with a small triangle. 4. Carefully insert the CPU into the socket until it fits in place. 5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked. 6. Install a CPU heatsink and fan following the instructions that came with the heatsink package. Gold triangle Small triangle

2-9 2.3.2 Installing the heatsink and fan The AMD Athlon™ 64FX/Athlon™ 64/Athlon™ 64 X2/Sempron™ processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. To install the CPU heatsink and fan: 1. Place the heatsink on top of the installed CPU, making sure that the heatsink fits properly on the retention module base. Retention module base CPU heatsink CPU fan Retention bracket lock Retention bracket Your boxed CPU heatsink and fan assembly 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. • The retention module base is already installed on the motherboard upon purchase. • You do not have to remove the retention module base when installing the CPU or installing other motherboard components. • 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. Make sure that you use only AMD-certified heatsink and fan assembly.

2. Attach one end of the retention bracket to the retention module base. 3. Align the other end of the retention bracket (near the retention bracket lock) to the retention module base. A clicking sound denotes that the retention bracket is in place. 4. Push down the retention bracket lock on the retention mechanism to secure the heatsink and fan to the module base. Make sure that the fan and heatsink assembly perfectly fits the retention mechanism module base, otherwise you cannot snap the retention bracket in place.

2-11 5. When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN. Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector. M2N32 WS PRO ® M2N32 WS PRO CPU fan connector CPU_FAN GND CPU FAN PWR CPU FAN IN CPU FAN PWM

2.4 System memory 2.4.1 Overview The motherboard comes with four 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 figure illustrates the location of the DDR2 DIMM sockets: Channel Sockets Channel 1 DIMM_A1 and DIMM_B1 Channel 2 DIMM_A2 and DIMM_B2 M2N32 WS PRO ® M2N32 WS PRO 240-pin DDR2 DIMM sockets DIMM_B1 DIMM_A1 DIMM_B2 DIMM_A2

2-13 2.4.2 Memory configurations You may install 256 MB, 512 MB, and 1 GB unbuffered ECC/non-ECC DDR2 DIMMs into the DIMM sockets. Important notice on installing Windows® XP 32-bit version If you install Windows® XP 32-bit version Operating System (OS), the limitation of this OS version is that it may reserve a certain amount of memory space for system devices. We recommend that you install less than 3 GB system memory if you would like to work under Windows® XP 32-bit version OS. The excess memory installation will not cause any usage problem, but it will not give users the benefit of manipulating this excess memory space. Visit the ASUS FAQ site for further explanation: http://support.asus.com/faq/faq. aspx?SLanguage=en-us Under General Search, make the selections as shown, then click Search. Click the article titled “4GB memory installed but less memory size detected.” You also may check the URLs below for third party comments on this issue: http://dlsvr01.asus.com/pub/ASUS/mb/4GB_Rev1.pdf http://www.intel.com/support/motherboards/server/sb/cs-016594.htm • 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, we recommend that you obtain memory modules from the same vendor. Visit the ASUS website (www.asus.com) for the latest Qualified Vendors List. • When using only one DDR2 DIMM module, install it into slot DIMM_A1 only. • For single-channel memory configuration, start installing the DDR2 DIMMs from slot DIMM_A1 or DIMM_B1. • For dual-channel memory configuration, install the DIMMs in slots DIMM_B1 and DIMM_A1 (yellow slots); install another pair of DIMMs in slots DIMM_B2 and DIMM_A2 (black slots).

The DIMM might get damaged when it flips out with extra force. 1 2 1 DDR2 DIMM notch Unlocked retaining clip DDR2 DIMM notch 1 2 3

2.5 Expansion slots In the future, you may need to install expansion cards. The following sub‑sections describe the slots and the expansion cards that they support. 2.5.1 Installing an expansion card To install an expansion card: 1. Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings for the card. 2. Remove the system unit cover (if your motherboard is already installed in a chassis). 3. Remove the bracket opposite the slot that you intend to use. Keep the screw for later use. 4. Align the card connector with the slot and press firmly until the card is completely seated on the slot. 5. Secure the card to the chassis with the screw you removed earlier. 6. Replace the system cover. 2.5.2 Configuring an expansion card After installing the expansion card, configure the it by adjusting the software settings. 1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 4 for information on BIOS setup. 2. Assign an IRQ to the card. Refer to the tables on the next page. 3. Install the software drivers for the expansion card. Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that the cards do not need IRQ assignments; otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable.

2-25 2.6 Jumper Clear RTC RAM (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. Remove the onboard battery. 3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2. 4. Reinstall the battery. 5. Plug the power cord and turn ON the computer. 6. Hold down the key during the boot process and enter BIOS setup to re-enter data. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure! • Make sure to re-enter your previous BIOS settings after you clear the CMOS. • You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values.
