Performance

ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more Energy Saving Features for operating systems that support OS Direct Power Management (OSPM) functionality. With these features employed in the OS, PCs can be ready around the clock but comply with energy saving standards. To fully utilize the ACPI benefits, use an ACPI-supported OS such as Windows 98/ME/2000. PC99 Compliant: Both the BIOS and hardware levels of ASUS smart series motherboards are PC99 compliant. The new PC99 requirements for systems and components are based on the following high-level goals: Support for Plugn-Play compatibility and power management for configuring and managing all system components, and 32-bit device drivers and installation procedures for Windows 98/ME/2000. Color-coded connectors and descriptive icons make identification easy as required by PC99. High-Speed Data Transfer Interface: Support for UltraDMA/100 through the onboard IDE bus master controller. doubles the UltraDMA/33 burst transfer rate to 66.6MB/s. UltraDMA/100 is backward compatible with DMA/66, DMA/33, and other existing DMA devices to save the need to upgrade current EIDE/IDE drives. (UltraDMA/100/66 requires a 40-pin 80-conductor cable). Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master busses to the memory and processor. VCM/SDRAM Optimized Performance: This motherboard supports the new generation memory, NEC 64Mb Virtual Channel Memory (VCM) Synchronous Dynamic Random Access Memory (SDRAM), that is compatible to the industry standard SDRAM. The VCM core design provides up to 50% higher SDRAM speed at reduced power consumption of about 30%. This motherboard also supports the standard SDRAM for a the data transfer rate of up to 1.067GB/s using PC133-compliant SDRAMs and up to 800MB/s using PC100-compliant SDRAMs. Power Saving Feature: Suspend-to-RAM (STR) provides maximum power savings as an alternative to leaving the computer ON. STR allows QuickStart when you get back , so you dont have to go through the long boot process. (NOTE: This motherboard does not support the Suspend-to-RAM (STR) feature when you install a DIMM into the DIMM4 socket.)

2. FEATURES Features

Intelligence
Auto Fan Off: The system fans powers off automatically even in sleep mode. This function reduces both energy consumption and system noise, and is an important feature in implementing Silent PC systems. Dual Function Power Button: Pushing the power button for less than 4 seconds when the system is in the working state places the system into one of two states: sleep mode or soft-off mode, depending on the BIOS or OS setting (see PWR Button < 4 Secs in 4.5 Power Menu). When the power button is pressed for more than 4 seconds, the system enters the soft-off mode regardless of the BIOS setting. Fan Status Monitoring and Alarm: To prevent system overheat and system damage, the CPU and system fans can be monitored for RPM and failure. All fans are set for its normal RPM range and alarm thresholds. Power LED (requires ACPI OS support): The power LED indicates the system status. Remote Ring-On (requires modem): This allows a computer to be turned on remotely through an internal or external modem. With this benefit on-hand, users can access vital information from their computers anywhere. System Resources Alert: Todays operating systems such as Windows 95/98/ 2000/NT and OS/2, require much more memory and hard drive space to present enormous user interfaces and run large applications. The system resource monitor warns the user before the system resources are used up to prevent possible application crashes. Suggestions provide the user some information on managing their limited resources more efficiently. Temperature Monitoring and Alert: CPU temperature is monitored by the ASUS ASIC through the CPUs internal thermal diode (on Pentium III and Celeron) to prevent system overheat and system damage. Voltage Monitoring and Alert: System voltage levels are monitored to ensure stable voltage to critical motherboard components. Voltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management. Chassis Intrusion Detection: Supports chassis-intrusion monitoring through the ASUS ASIC. A chassis intrusion event is kept in memory on battery power for more protection.

CUV4X-E VIO Setting

WARNING! Using a higher voltage may help when overclocking the processor but it may shorten the life of system components. As much as possible, keep the VIO jumper to its default setting for better system stability. 5) Clear RTC RAM These two solder points allow 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 RAM data in CMOS, that include system setup information such as system passwords, is powered by the onboard button cell battery. To erase the RTC RAM: (1) unplug the computer, (2) short the solder points, (3) turn ON the computer, (4) hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.

WARNING! Make sure that the DIMM you use can handle the specified SDRAM speeds, otherwise the computer does not boot.
3. H/W SETUP System Memory
Install memory in any combination as follows:
3.5.2 Memory Installation
WARNING! Make sure that you unplug the power supply when adding or removing memory modules or other system components. Failure to do so may cause severe damage to both the motherboard and expansion cards (see 3.3 Hardware Setup Procedure for more information). Insert the module(s) into the DIMM sockets as shown. Because the number of pins are different on either side of the breaks, the module only fits in one direction. SDRAM DIMMs have different pin contacts on each side and have a higher pin density than DRAM SIMMs.

88 Pins

60 Pins 20 Pins
CUV4X-E 168-Pin DIMM Sockets
The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type, check the notches on the DIMMs (see the figure below).
The notches on the DIMM shifts between left, center, or right to identify the type and also to prevent the wrong type from being inserted into the DIMM slot on the motherboard. You must tell your retailer the correct DIMM type before purchasing. This motherboard supports four clock signals per DIMM.
3.6 Central Processing Unit (CPU)
The motherboard comes with a ZIF Socket for the supported CPUs listed in section 2.1.1 Specifications. The following illustration shows the CPU socket location on the motherboard and the correct CPU orientation.
Socket 370 CPU (Top) Socket 370 CPU (Bottom)

Celeron

Pentium III CUV4X-E Socket 370

Gold Arrow

Note in the illustration that CPUs have marks (usually a notch or a gold mark on one corner) to help you identify the proper orientation and enable you to correctly install a CPU. It is important that you match the marked corner of the CPU with the corresponding corner on the socket so as not to damage the CPU pins. The CPU picture above is for reference only. Usually, when you buy a CPU, the heatsink and fan are already attached to the CPU. If a heatsink and fan did not come with the package, make sure you obtain one before installing the CPU. WARNING! You must install the proper heatsink and fan to the CPU. Failure to do so will cause the CPU to overheat and may damage both the CPU and the motherboard. Install an auxillary fan, if necessary. CAUTION! Be careful not to scrape the motherboard when mounting/unmounting a clamp-style processor fan to avoid damaging the motherboard.
Proceed to the next section for the steps on how to properly install a CPU.

3. H/W SETUP CPU

3.6.1 CPU Installation
Follow these steps to install a CPU. 1. Locate the ZIF socket on the motherboard. 2. Unlock the socket by pressing the lever sideways then lifting it up to a 90-100 angle.
3. Position the CPU above the socket such that its notched or marked corner matches the socket corner near the end of the lever, while making sure that the CPU is parallel to the socket. 4. Carefuly insert the CPU into the socket until it fits in place.

3. H/W SETUP CPU Installation
CAUTION! The CPU fits only in one orientation. Do not force the CPU into the socket to prevent bending the pins and damaging the CPU. If the CPU does not fit completely, check its orientation or check for bent pins.
5. When the CPU is in place, press it firmly on the socket while you push down the socket lever to secure the CPU. The lever clicks on the socket indicating that it is locked. 6. Attach the heatsink and fan to the CPU, if they were not pre-installed by the vendor. Refer to the installation instructions that came with the heatsink and fan. NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency multiple setting is available only on unlocked processors) for the processor to avoid start-up problems.

3.7 Expansion Cards

In the future, you may need to install expansion cards. The motherboard has six PCI expansion slots to support these cards. Follow the steps in the next section when installing expansion cards. WARNING! Unplug the system power cord when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both the motherboard and expansion cards.
3.7.1 Installing an Expansion Card
1. Read the documentation that comes with the expansion card and make any necessary hardware settings for the card before installing it. 2. Remove the system unit cover and the bracket plate on the slot you intend to use. Keep the screw for later use. 3. Align the card connectors with the slot and press firmly until the card fits in place. 4. Secure the card to the slot with the screw you removed earlier. 5. Replace the system cover. 6. Change the necessary BIOS settings, if any. (see section 4.4.3 PCI Configuration to change the settings.) 7. Install the necessary software drivers for the expansion card.
3. H/W SETUP Expansion Cards
3.7.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclusively assigned to one use. In a standard design, there are 16 IRQs available but most of them are already in use, leaving 6 IRQs free for expansion cards. IMPORTANT: If using PCI cards on shared slots, make sure that the drivers support Share IRQ or that the cards do not need IRQ assignments. Conflicts arise between the two PCI groups that makes the system unstable or cards inoperable. The following table lists the default IRQ assignments for standard PC devices. Use this table when configuring your system and for resolving IRQ conflicts.

3.7.4 Audio Modem Riser (AMR) Slot
The AMR slot support a specially designed audio and/or modem card called an Audio Modem Riser (AMR). Main processing is done through software and controlled by the system chipset. There are two types of AMR, one defined as primary and another defined as secondary. You can only use primary AMRs with this motherboard. (NOTE: The motherboard package does not include the AMR card.) IMPORTANT The AMR slot shares the same expansion slot with PCI Slot 6. Because of space limitation, the AMR slot can support only specially designed AMR cards. The components of a standard AMR card and its bracket face toward the edge of the motherboard, while those of a specially designed AMR card face the expansion slots.

No sound

Is the MIDI driver correctly installed? Is the tone generator set correctly? Is volume set to zero in the XGstudio Player or XGstudio Mixer panels? If you are using an external tone generator, is the serial or MIDI cable and the audio cables connected correctly? Are the volumes of your tone generator, audio playback system, and application raised? If you have connected an external tone generator via a serial cable, is the rear panel select switch set correctly? (For the name of the select switch, refer to the owner's manual for your external tone generator.) If you are using a Soft Synthesizer, is it set so that the computer sound output is heard correctly?
