System Memory Combinations
The Intel® Desktop Board SU810 has two, dual inline memory module (DIMM) sockets. Minimum memory size is 32 MB; maximum memory size is 512 MB. The BIOS automatically detects memory type, size, and speed.

The desktop board supports the following memory features:

  • 168-pin DIMMs with gold-plated contacts
  • 100 MHz SDRAM
  • Non-ECC (64-bit) memory
  • 3.3 V memory only
  • 100 MHz memory may be either Serial Presence Detect (SPD) or non-SPD memory
  • Unbuffered Single- or double-sided DIMMs in the following sizes:
DIMM Size Non-ECC Configuration
16 MB 2M x 64
32 MB 4M x 64
64 MB 8M x 64
128 MB 16M x 64
256 MB 32M x 64


Note Because the main system memory is also used as video memory, the Intel Desktop Board SU810 require 100 MHz SDRAM DIMMs even though the processor front side bus is 66 MHz. It is highly recommended that SPD DIMMs be used, since this allows the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted.

All memory components and DIMMs used with the Intel Desktop Board SU810 must comply with the PC SDRAM Unbuffered DIMM Specification. See Section 1.3 of the Intel Desktop Board SU810 Technical Product Specification for information about this SDRAM DIMM specification.

Frequently Asked Questions: Intel Desktop Board SU810

General Questions
  • Which processors does the Intel® Desktop Board SU810 support?
    See the Processor Support Table for details.

  • What is the processor socket on the Intel® Desktop Board SU810 called? Is it Socket 7?
    The processor socket on the Intel Desktop Board SU810 is referred to as a 370-pin socket and is not the socket 7. The Intel Celeron processor in the PPGA package is designed specifically for the P6 bus, like the Pentium® III processors, Pentium® II processors and Pentium®Pro processors. As such, it has a different pin-out than the Pentium processor family of products.

  • How do I install and secure an Intel Celeron processor on the Intel Desktop Board SU810?
    The processor connects to the Intel Desktop Board SU810 through the 370-pin socket connector. This Zero Insertion Force (ZIF) connector does not require any additional hardware to integrate the processor.

  • What new features are incorporated into the Intel® 810 chipset?
    The Intel 810 chipset features integrated 3D video graphics. The integrated video utilizes Dynamic Video Memory Technology (D.V.M.T.) to efficiently access main memory to support video display. The benefit is smart integration that reduces overall system cost. In addition, the Intel 810 chipset supports Ultra ATA/66 hard drives, the S3 state of Suspend to RAM (STR) as well as faster I/O hub architecture.

  • What kind of expansion slots does the boxed Intel® Desktop Board SU810 support at the NLX card edge connector?
    The ICH on the Intel Desktop Board SU810 supports a total of five PCI bus masters. If PCI LAN is integrated on the desktop board, there is a maximum of four PCI bus masters available to an NLX riser. If LAN is not integrated on to the desktop board there are a maximum of five. Any additional PCI bus connectors on an NLX riser will not support bus mastering.
    ISA bus signals (as defined in the NLX Riser specification) are not provided on the Intel Desktop Board SU810 at the NLX riser card edge connector.
    For additional information on the NLX Card Edge Connector of the Intel Desktop Board SU810 refer to the Technical Product Specification.

  • Does the Intel Desktop Board SU810 support STR (Suspend to RAM)?
    The Intel Desktop Board SU810 supports STR but the operating system and the applications being used must also support STR. Operating systems and applications that do not support STR can cause problems when coming out of different sleep states.


Memory
  • What is SDRAM memory?
    Synchronous DRAM (SDRAM) improves memory performance through memory access that is synchronous with the memory clock. This simplifies the timing design and increases memory speed, because all timing is dependent on the number of memory clock cycles.

  • What types of memory modules can I install on the Intel® Desktop Board SU810?
    The Intel Desktop Board SU810 supports dynamic memory detection for one or two 3.3 V, 168-pin, 4-clock, 100-MHz unbuffered SDRAM DIMMs.
    Note: The Intel Desktop Board SU810 BIOS will support SPD and non-SPD, 100-MHz SDRAM DIMMs. To achieve optimum performance, SDRAM DIMMs must meet SPD information requirements. For best performance and reliability, using SPD DIMMs listed on the compatible memory list is highly recommended. SDRAM SPD information must be programmed by the memory manufacturer in accordance with the JEDEC MO-161 specification.

  • What memory configurations are supported on the Intel Desktop Board SU810?
    The Intel Desktop Board SU810 has two dual in-line memory module (DIMM) sockets that support 100MHz SDRAM DIMMs. Memory can be installed in one or two of the DIMM sockets. The Intel Desktop Board SU810 can support minimum system memory configurations of 32 MB and a maximum configuration of 512 MB. The Intel Desktop Board SU810 supports memory sizes of 16 MB or 32 MB using 16-Mbit technology; 32 MB, 64 MB or 128 MB using 64-Mbit technology; and 256 MB using 128-Mbit technology.



    Note: The Direct Video Memory Technology Subsystem driver allocates system memory to act as video memory. The size of the memory allocation is dependant upon the size of the display cache. The standard Intel Desktop Board SU810 has no display cache so 10MB allocation is required; 2MB for commands, 4MB for Graphics Surfaces, and 4MB for Display. A minimum of 64 MB of system memory is recommended.

  • I get the message "SERIAL PRESENCE DETECT (SPD) device data missing or inconclusive." when the system is booting. What does this mean?
    If during POST, non-SPD memory is detected or the BIOS cannot determine that the memory installed meets SPD 100-MHz requirements, the desktop board BIOS will display this message:

    SERIAL PRESENCE DETECT (SPD) device data missing or inconclusive. 

    Properly programmed SPD device data is required for reliable operation.  
    Do you wish to continue? Y/N Type [Y] to continue, [N] to shut down
    • Thereafter, while non-SPD memory remains present, the boot screen will display the following message:
    SERIAL PRESENCE DETECT (SPD) device data missing or inconclusive.  
    100 MHz memory assumed.


    SPD 100-MHz memory may not be readily available in some locations. Also, some operators may not have critical data integrity requirements. If SPD 100-MHz memory cannot be confirmed during POST, the BIOS will provide this information to the user and offer the option to run the system with memory that may not meet the full 100-MHz operating requirements.
    If the system will be used in a mission-critical application where data integrity is vital, the system should be shut down and SPD 100-MHz memory installed prior to operation.
    See the Intel Desktop Board SU810 tested-memory list, for a listing of tested memory for your desktop board.



  • What kind of problems might occur in an SDRAM-based system that uses non-compliant DIMMs?
    The most extreme example of memory failure is when the system hangs while booting the operating system. This can happen when the system is unable to communicate properly with the memory. In less extreme cases, the memory may generate intermittent errors or fail during stress.

  • I get a repeating-beep error code and my desktop board does not boot or show any video. What does this mean?
    This beep code may indicate a problem during detection of the DRAM memory device. Check to ensure that system memory is properly installed and that the DIMMs are on the Intel Desktop Board SU810 tested-memory list.

  • Does Intel qualify memory for use on Intel® desktop boards?
    No. OEMs and system integrators are solely responsible for qualifying the memory they include in their systems. Intel performs only limited testing of selected memory modules to verify functionality of the desktop board's design. Intel offers a program for third parties to self-test their system's memory and to report passing results to Intel for inclusion on our Internet-based tested-memory list.


NLX Chassis
  • Do I need a special chassis for NLX desktop boards?
    Yes, The Intel Desktop Board SU810 is a NLX Platform and requires a chassis that is compliant with the NLX 1.2 specification. There are no Power supply, I/O slots or data connectors on the Intel Desktop Board SU810. Power, I/O and data connectors reside on an NLX 1.2 compliant riser card. Riser cards may be specific to chassis style or sold by third party vendors. Reference the NLX web site for vendor information. Note: A thorough evaluation should be performed by the system manufacturer on the selected NLX or microNLX (uNLX) chassis. The system manufacturer is responsible for ensuring adequate airflow and cooling for the processor.


Power Supply
  • What special power supply requirements does the Intel® Desktop Board SU810 have?
    The Intel Desktop Board SU810 is designed to operate with at least a 145 Watt power supply for typical system configurations. A higher-wattage supply may be required for heavily-loaded configurations. The power supply must provide +5 Voltage Stand By (+5VSB) with 720mA of current (reference the NLX Power Supply Recommendation V1.1). If the power supply does not supply sufficient current, some system configurations with the Intel Desktop Board SU810 may not power up. Additionally, if the power supply can not supply sufficient current, and does not have overload protection, the power supply may be damaged.

  • Why do I need a power supply with 720mA of current on the +5VSB power supply for the Intel Desktop Board SU810?
    The Intel Desktop Board SU810 requires a 3.3 volt power supply that complies with the NLX 1.2 specification. In order to utilize Wake on LAN technology capabilities, the Intel Desktop Board SU810 also requires a soft on/off power supply. It must provide a +5VSB with 720mA of standby current to keep the remote Wake on LAN circuit alive. Reference the NLX Power Supply Recommendation V1.1.

  • Why isn't there a power connector on my Intel® Desktop Board SU810?
    With the NLX form factor, the power to the desktop board is supplied through the riser card. This allows the easy removal of the "dockable" desktop board from the chassis. In fact, all power and data cables have been moved to the riser. Thus, an NLX 1.2 compliant riser is necessary to power the desktop board.

  • What power supply requirements does the Intel Desktop Board SU810 have if a WOL capable Network Interface Card (NIC) is installed?
    A power supply that provides at least 720mA on +5VSB must be used when building a WOL capable system. If your power supply is not capable of meeting the 720 mA current requirement, your system may not power up. Also you could experience damage to your power supply if it does not have any over-current protection. Please contact your system integrator to see if your power supply meets the 720 mA current requirement.
    If you are using a WOL capable NIC but are not using the WOL capability you can remove the cable from the NIC to the WOL header on the desktop board. This will prevent the NIC from drawing additional current from the +5VSB.


Jumpers/BIOS Setup Options
  • Why can't I find speed settings in my BIOS configuration mode?
    The processor speed option previously available in configuration mode is not displayed with newer Intel processors and will not affect the processor speed. Newer Intel processors boot with the ratio preset and are tested during manufacturing.

  • How should the jumpers be set on my Intel® Desktop Board SU810?
    A single configuration jumper on the desktop board is used to access configuration mode. All configuration options are made available through the BIOS configuration screens. Refer to the Intel Desktop Board SU810 Configuration Jumpers page.


Integrated Video
  • What architecture does the integrated video on the Intel 810 chipset use?
    The Intel 810 chipset incorporates Intel® 3D graphics. This new video graphic architecture is based on Direct AGP (Accelerated Graphics Port) and utilizes Dynamic Video Memory Technology (D.V.M.T.) to deliver 3D video quality through efficient memory use.

  • What is Dynamic Video Memory Technology (D.V.M.T.)?
    Dynamic Video Memory Technology delivers two key features to this video architecture: Direct AGP (Accelerated Graphics Port) and intelligent arbitration. Direct AGP dynamically and directly allocates and de-allocates system memory for 3D texturing, resulting in more life-like 3D video quality. Intelligent arbitration balances video and data streams between all system components (CPU, graphics subsystem, I/O and system memory), improving overall platform performance through efficient memory utilization.

  • How do I replace the onboard video with an add-in PCI video adapter?
    The primary video adapter can be changed from the onboard AGP to an add-in PCI adapter through the desktop board BIOS Setup utility. The setting is located in the Advanced screen under Video Configuration.


On-Board Audio
  • How can the onboard audio be disabled?
    The onboard audio can be disabled using the BIOS Setup Utility. Select the advanced menu, then the Peripheral Configuration screen. The menu offers options to enable or disable the audio if it is present on the desktop board. Refer to the Intel Desktop Board SU810 TPS (Technical Product Specification) for more details.

  • If audio is disabled, does the Intel® Desktop Board SU810 consume fewer interrupts?
    The Analog Devices ADI 1881 uses a maximum of two shareable PCI interrupts. Enabling or disabling the audio does not affect resource availability as the enabled resources use fully shareable PCI interrupts.

  • Is the audio solution PC98 Logo compliant?
    Yes. The Analog Devices ADI 1881 audio solution on the Intel Desktop Board SU810 platform is compliant to Microsoft PC97, Microsoft PC98, the AC97 interface and Multimedia PC Level II and III specifications.

  • Is the audio solution full duplex?
    Yes. The Analog Devices ADI 1881 audio solution is capable of playing and recording at different sample rates simultaneously. The solution also meets PC97 and PC98 requirements to support videophone operation.

  • Is the audio solution SoundBlaster* and SoundBlaster Pro compatible?
    Yes. Functionally, Creative Labs SoundBlaster audio PCI 128 traps accesses to the SoundBlaster registers and issues appropriate IRQ or SERR commands on the PCI bus. The DMA functionality is handled in a similar fashion.

  • What is AC97 and what does it do?
    The AC97 (Audio Codec 1997) specification defines a high-quality audio architecture that advances the migration to digital audio, while maintaining support for analog interconnects for backward compatibility.

  • Does the Intel Desktop Board SU810 support digital audio?
    Yes. The Intel Desktop Board SU810 supports digital wave files and midi files.

  • Does this audio solution have a hardware wave table? Wave-table add-on? Software wave-table driver available in standard-driver package?
    The Analog Devices ADI 1881 audio solution includes a 128-voice polyphony software wave-table audio solution in the driver package, so a hardware wave-table add-on is not required. The software wave table is compatible with the aureal* API for 3D Positional audio. More than 4,000 sounds are stored in main memory. User selectable wavetable comes in sizes of 2, 4 or 8 megabytes.

  • How many channels or MIDI voices does this solution have?
    The Analog Devices ADI 1881 audio solution provides a 128-voice polyphony wave-table audio solution.

    Drivers are available on the Intel Desktop Board SU810 Web site for the Analog Devices ADI 1881 audio solution to support Windows NT 4.0, Windows 95 and Windows 98. The MS-DOS drivers will be installed as part of the Windows 9x drivers. At this time, Intel has no plans to make audio drivers available for other operating systems.

  • Are drivers available for OS/2*?
    Intel does not provide audio drivers for the Analog Devices ADI 1881 audio solution running with OS/2.


Input/Output
  • Does the Intel Desktop Board SU810 support Ultra ATA/66 hard drives?
    Yes. One of the new features of the Intel 810 chipset is its ability to support both Ultra ATA transfer rates (i.e., 33 MB/sec and 66 MB/sec). To use Ultra ATA/66 features, the following items are required:
    • An Ultra ATA/66 capable NLX riser
    • An Ultra ATA/66 peripheral device
    • An Ultra ATA/66 compatible cable
    • Ultra ATA/66 operating system device drivers
    To realize a true throughput performance difference, a hard drive may need to implement higher spindle speeds, such as 7200 RPM, and a large onboard buffer size to take advantage of the increased bandwidth available on the IDE channel.

  • What kind of IDE cable is needed for the Intel® Desktop Board SU810 to support both Ultra ATA/66 and previous IDE transfer protocols?
    A 40-pin, 80-conductor cable is fully backward compatible with all IDE transfer protocols and also supports Ultra ATA/66 if used with one or two Ultra ATA/66 drives attached. If a drive using a previous IDE transfer protocol is attached to the provided cable, the maximum transfer protocol available to either drive on the cable will be UDMA33. Ultra ATA/66 drives may be used in a system with IDE drives that use older transfer protocols. It is recommended that the Ultra ATA/66 drives be attached to the primary IDE channel using a 40-pin, 80-conductor cable and that the other drives be attached to the secondary channel using a good quality, 40-pin 40-conductor IDE cable.
    Note: Some UDMA cables use a hole in the ribbon cable as a cable detect mechanism to determine if a UDMA IDE or standard IDE cable is installed.

  • What type of battery is used in the Intel Desktop Board SU810?
    Standard (3 volt, CR2032) coin cell is used to supply power to the RTC when power is not available from the power supply.

  • How do I disable the onboard LAN?
    Onboard LAN can be disabled through the desktop board BIOS Setup utility. The setting is located in the Advanced screen under Peripheral Configuration. Refer to the Intel Desktop Board SU810 TPS (Technical Product Specification) for more details.

  • Why doesn't my Intel Desktop Board SU810 power-up?
    The Intel Desktop Board SU810 requires 3.3 volts from the power supply, as well as specific requirements for the power sequencing and limits. A momentary switch should be used for the power on/off switch and the sleep/resume switch. The power supply chosen must meet the ATX 2.01 or later specification.

  • Why are the drivers on Intel's public Web site revisions of those available on some vendor public Web sites?
    Intel performs internal testing on all drivers before posting them on the Intel developer desktop board Web site. In many cases, it is not practical to test all drivers on all desktop boards. For this reason, application vendors may release drivers that have not been tested by Intel. These drivers may be available on the vendor public site, but not on the Intel public site. This does not mean the drivers do not work; it simply indicates that Intel has not validated the drivers.

  • Why doesn't my CD-ROM or second IDE hard drive work with Windows* 95?
    Two known issues involve CD-ROM or secondary hard drives: First, Windows 95 or Windows 98 may not correctly recognize the Intel® 82801AA ICH IDE controller used on Intel desktop boards, causing the BIOS to disable the secondary IDE channel. This can result in IDE devices, such as CD-ROM drives, not being detected or disappearing after the system is rebooted. A utility is available to update the MSHDC.INF file and resolve the issue. As a temporary work-around, the CD-ROM can be installed on the primary IDE channel until the INF update utility has been run. Second, Windows 95 or Windows 98 may fail to recognize a CD-ROM drive that does not comply with the ATAPI specification.

  • Does the Intel Desktop Board SU810 support two serial ports?
    Yes. The second serial port is available via a header on the desktop board and requires an adapter cable to access. A cable can be obtained from FOXCONN, part #F509635-00. Other vendors may also stock a compatible adapter cable. A header pinout diagram can be found in the Technical Product Specification.

  • Why isn't my IDE device displayed during power-up POST?
    All IDE devices must be ATA4 compliant. Cable length is limited to 18 inches. IDE devices not selected as auto-detect in the BIOS setup are not displayed as part of the POST tests.

  • Can I use a second floppy on my Intel® Desktop Board SU810?
    No. The Intel Desktop Board SU810 uses a SMSC LPC47B272 SIO component to support the floppy-disk controller. This component and equivalent components can support a single standard-legacy type FDD, a 2.88 MB Super I/O type FDD, or a three-mode type FDD.
