Tested memory
End of Interactive Support
Intel is announcing the end of interactive support for the Intel® CA810 Motherboard. See the End of Interactive Support Announcement for details.

Important Notes System Memory Combinations

The motherboard has two, dual inline memory module (DIMM) sockets. Minimum memory size is 32 MB (using one 32 MB DIMM or two 16 MB DIMMs); maximum memory size is 512 MB. Due to the video requirements of the Intel CA810 Motherboard, minimum memory for the Windows NT* 4.0 operating system is 64 MB. The BIOS automatically detects memory type, size, and speed.

The motherboard supports the following memory features:

  • 168-pin DIMMs with gold-plated contacts
  • 100 MHz SDRAM
  • Non-ECC (64-bit)
  • 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 CA810 Motherboard 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 CA810 Motherboard must comply with the PC SDRAM Unbuffered DIMM Specification. You can access this document through the Internet at: http://www.intel.com/technology/memory/index.htm See Section 6.2 for information about this SDRAM DIMM specification.

Frequently Asked Questions: Intel® CA810 Motherboard

General Questions

  • Which processors does the Intel® CA810 Motherboard support?
    See the Processor Support Table for details.

  • What is the processor socket on the Intel® CA810 Motherboard called? Is it Socket 7?
    The processor socket on the Intel® CA810 Motherboard 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 Intel® Pentium® III, Pentium® II 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® CA810 Motherboard?
    The processor connects to the Intel® CA810 Motherboard through the 370-pin socket connector. This Zero Insertion Force (ZIF) connector does not require any additional hardware to integrate the processor.

  • The Intel® CA810 Motherboard incorporates the Plastic Pin Grid Array (PPGA) form factor socket connector. Why is Intel switching to the PPGA package?
    Intel develops unique products that meet the specific needs of each market segment. In the Value PC market segment, for example, we work to provide our customers a quality, low-cost platform. Some of the ways Intel works to reduce platform costs in product design and development of industry standards are in:

    • CPU packaging (e.g., Intel Celeron processors in a PPGA package)
    • Motherboard form factor (microATX)
    • Chipset (e.g., Intel® 810 chipset)
    • Power supply (microATX power supply)
    • Integration (e.g., integrated processor/L2 cache; integrated chipset/graphics)
  • How quickly will Intel transition the Intel Celeron processor family to the Plastic Pin Grid Array (PPGA) package?
    Intel is transitioning the Intel Celeron processor product line to the Plastic Pin Grid Array (PPGA) package during the first half of 1999. Future Intel Celeron processors will be introduced in the PPGA package only. Customers are encouraged to transition their Intel Celeron processor-based systems to the PPGA package immediately, as the Single Edge Processor Package (S.E.P.P) is being eliminated.

  • What new features are incorporated into the Intel® 810 chipset?
    The Intel 810 chipset features integrated 3D video graphics that render obsolete the need for a separate add-in card. This chipset integration means that the video drivers have been validated with the rest of the motherboard components, ensuring seamless compatibility. 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 is included in the boxed Intel® CA810 Motherboard for system integrators?
    The boxed Intel® CA810 Motherboard is packaged in a single- pack and in an augmented ten-pack. It includes a motherboard, I/O shield, Quick Start Guide, floppy cable, IDE cable (Ultra ATA/66 capable), adjustable stand-off for backward compatibility to standard ATX chassis, CD-ROM with video driver, audio drivers, Intel® 810 Chipset inf update, warranty information, board manual, Norton AntiVirus* software and several useful Internet utilities. The Intel® 82559 LAN drivers and LANDesk* Client Manager also ships on the CD that comes with the LAN version of this board. The bulk-pack contents differ slightly, as they include only a single copy of the Quick Start Guide.

  • How many expansion slots does the boxed Intel® CA810 Motherboard contain?
    There are four dedicated PCI slots. This configuration allows for a maximum of four add-in cards to be integrated with this board. All PCI slots support bus-mastering devices.

  • Does the Intel® CA810 Motherboard support STR (Suspend to RAM)?
    The Intel® CA810 Motherboard supports STR but the OS 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.

  • Why does the Windows* 95 device manager report a resource conflict with my add-in card and onboard PCI devices?
    Windows* 95 device manager reports a conflict with a "Intel® 82810 Processor to AGP controller" for AGP cards. For PCI cards and onboard PCI devices the Windows 95 device manager reports a conflict with a "Intel® 82801AA PCI Bridge". The "Intel® 82810 Processor to AGP controller" and the "Intel® 82801AA PCI Bridge" are both components of the Intel® 82810 chipset which Windows 95 cannot properly identify. This issue will not affect the functionality of Windows 95, with AGP or PCI devices.

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® CA810 Motherboard?
    The Intel® CA810 Motherboard supports dynamic memory detection for one or two 3.3 V, 168-pin, 4-clock, 100-MHz unbuffered SDRAM DIMMs.

    Note: The Intel® CA810 Motherboard BIOS will support SPD (serial presents detect) 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® CA810 Motherboard?
    The Intel® CA810 Motherboard 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® CA810 Motherboard can support minimum system memory configurations of 32 MB and a maximum configuration of 512 MB. The Intel® CA810 Motherboard 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 CA810 board 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 motherboard 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® CA810 Motherboard tested-memory list, for a listing of tested memory for your motherboard.

  • 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 motherboard 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® CA810 Motherboard tested-memory list.

  • Does Intel qualify memory for use on Intel motherboards?
    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 motherboard'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.

MicroATX/ATX Chassis

  • What is the difference between the ATX and the microATX (µATX) chassis?
    The microATX specification, released in January 1998, is a derivative of the ATX2.01 specification. The purpose behind drafting this specification is to provide a lower-cost platform solution that is backward compatible to standard ATX2.01. The microATX motherboard may be integrated into either a full-size ATX or a microATX chassis that meets the ATX2.01 specification. The Intel® CA810 Motherboard comes with an assembly standoff to allow for backward compatibility to ATX chassis. More detailed information is available on their dedicated Web site at: http://www.formfactors.org.

    Note: A thorough evaluation should be performed by the system manufacturer on the selected ATX or microATX ( µATX) chassis. The system manufacturer is responsible for ensuring adequate airflow and cooling for the processor.

  • Do I need a special chassis for microATX motherboards?
    A microATX motherboard can be integrated into a micro tower chassis and powered by lower wattage power supplies. However, the Intel® CA810 Motherboard ships with a standoff assembly to allow for backward compatibility to ATX chassis.

  • Are there any special thermal requirements for the Intel® CA810 Motherboard?
    Intel recommends that integrators ensure adequate ventilation and cooling when integrating the Intel® CA810 Motherboard with a microATX chassis.


Power Supply

  • Does the Intel® CA810 Motherboard have any special power-supply requirements?
    The Intel® CA810 Motherboard 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 VSB with 720ma of current (see the ATX2.01 or later specification). If the power supply does not provide sufficient current, some system configurations with the Intel® CA810 Motherboard may not power up. Additionally, if the power supply cannot supply sufficient current and does not have overload protection, the power supply may be damaged.

  • What are the power supply requirements if the Wake on LAN* (WOL) capabilities of the on-board Intel® 82559 LAN controller are utilized?
    A power supply that provides at least 720ma on 5 VSB must be used when building a WOL-capable system. If the power supply is not capable of meeting the 720 ma current requirement, the system may not power up. Also, the power supply may become damaged if it does not have any over-current protection. Please contact your system integrator to determine whether your power supply meets the 720ma 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 motherboard. This will prevent the NIC from drawing additional current from the 5 VSB.


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® CA810 Motherboard?
    A single configuration jumper on the motherboard is used to access configuration mode. All configuration options are made available through the BIOS configuration screens.

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 life-like 3D video quality through efficient memory use.

  • What benefits can I expect from the integrated video graphics on the Intel 810 chipset?
    With the inclusion of 3D graphics into the Intel 810 chipset, system builders can now integrate complete Value PCs at an overall lower cost. There is no longer the need for separate graphic add-in cards. This minimizes integration time and eliminates the frustration of component incompatibility. Because the boxed Intel® CA810 Motherboard ships with a complete set of graphic and audio drivers, you can be assured that full certification and testing has been performed. The Intel® CA810 Motherboard is a comprehensive and completely compatible Value PC platform.

  • 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 motherboard 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 motherboard. Refer to your Product Guide on the CD-ROM that ships with the boxed product or refer to the Intel® CA810 Motherboard TPS (Technical Product Specification) for more details.

  • If audio is disabled, does the Intel® CA810 Motherboard consume fewer interrupts?
    Creative Labs* SoundBlaster* audio PCI 128 audio solution 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 Creative Labs SoundBlaster audio PCI 128 audio solution PC98 Logo compliant?

  • Are drivers available for OS/2?
    Intel is not aware of available audio drivers for Creative Labs SoundBlaster audio PCI 128-audio solution running with OS/2.

Input/Output

  • Does the Intel® CA810 Motherboard 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 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.

  • Does the IDE cable provided with the Intel® CA810 Motherboard support both Ultra ATA/66 and previous IDE transfer protocols.
    The 40-pin, 80-conductor cable that is provided with the Intel® CA810 Motherboard is fully backward compatible with all IDE transfer protocols. It will also support 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 the provided cable and that the other drives be attached to the secondary channel using a good quality, 40-pin 40-conductor IDE cable, which is not provided with the motherboard.

    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® CA810 Motherboard?
    Standard (3 volt, CR3032) 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 motherboard BIOS Setup utility. The setting is located in the Advanced screen under Peripheral Configuration. Refer to the Intel® CA810 Motherboard TPS (Technical Product Specification) for more details.

  • Why doesn't my Intel® CA810 Motherboard power-up?
    The Intel® CA810 Motherboard 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 motherboard Web site. In many cases, it is not practical to test all drivers on all motherboards. 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 motherboards, 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® CA810 Motherboard support two serial ports?
    Yes. The second serial port is available via a header on the motherboard and requires an adapter cable to access. A cable can be obtained from FOXCONN, part #FJ09635-00. Other vendors may also stock a compatible adapter cable. A header pinout diagram can be found in the Product Guide located on the installation CD.

  • 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® CA810 Motherboard?
    No. The Intel® CA810 Motherboard 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.

The Intel® CA810 Motherboard 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.

ATA-66 support
The Intel® CA810 chipset supports both Ultra ATA transfer rates (i.e. 33 MB/sec and 66 MB/sec). Hard drives supporting Ultra ATA/100 transfer rates implement higher spindle speeds, such as 7200 RPM, and have a larger onboard buffer size to maximize available bandwidth on the IDE channel.
