Compatibility

Supported processors

The Intel® SE440BX Motherboard supports these processors:

Processor Family	Processor Speed	Notes
Pentium® III processors	450 MHz	requires BIOS P11 or later
Pentium II processors	450 MHz	requires BIOS P09 or later
Pentium II processors	400 MHz 350 MHz 333 MHz 300 MHz 266 MHz 233 MHz

Notes:

Pentium® III processors that run internally faster than 450 MHz are not supported because the maximum Icc current required is greater than what can be supplied by the motherboard's on-board voltage regulator. For processor requirements, see the Pentium III processor datasheet.

While the Intel® Celeron® processor uses the same P6 micro architecture as the Pentium II processor, there are some differences. No qualification or compatibility testing has been performed using the Intel Celeron processor and the BIOS does not contain support for this processor. While the Intel Celeron processor may appear to work in a Intel SE440BX Motherboard, the reliability of operation is not known.

Warning: Processors not specifically listed by type and rated speed may have requirements that are not supported by the motherboard's design. Use of unsupported processors may result in improper operation, damage to the motherboard or processor, or reduced product life.

System Memory Combinations
The motherboard has three dual in-line memory module (DIMM) sockets. Minimum memory size is 8 MB; maximum memory size is 768 MB. The largest DIMM supported at this time is 256 MB unbuffered using 128 Mbit technology parts. The BIOS automatically detects memory type, size, and speed.

The motherboard supports the following memory features:

168-pin DIMMs with gold-plated contacts
66 or 100 MHz SDRAM
Non-ECC (64-bit) and ECC (72-bit) memory
3.3 V memory only
Unbuffered Single- or double-sided DIMMs in the following sizes:

DIMM Size	Non-ECC Configuration	ECC Configuration
8M	1M x 64	1M x72
16 MB	2M x 64	2M x 72
32 MB	4M x 64	4M x 72
64 MB	8M x 64	8M x 72
128 MB	16M x 64	16M x 72
256 MB	32M x 64	32M x 72

Synchronous DRAM (SDRAM) can be installed in one, two, or three sockets. EDO DIMMs are not supported. Memory size and speed can vary between sockets.

Note: Pentium® II processors with 100 MHz front-side bus should be paired only with 100 MHz SDRAM. Processors with 66 MHz front-side bus can be paired with either 66 MHz or 100 MHz SDRAM.

All memory components and DIMMs used with the Intel® SE440BX Motherboard should comply with the PC SDRAM specifications. These include: the PC SDRAM Specification (memory component specific), the PC Unbuffered DIMM Specification and the PC Serial Presence Detect Specification.

Note: It is recommended that SPD memory DIMMs be used with the Intel SE440BX Motherboard; however, the BIOS will allow the use of non-SPD DIMM memory.

DIMM Vendors - SDRAM ECC DIMMs
Error checking and correcting (ECC) memory detects multiple-bit errors and corrects single-bit errors. When ECC memory is installed, the BIOS supports both ECC and non-ECC mode. ECC mode is enabled in the Setup program. The BIOS automatically detects if ECC memory is installed and provides the Setup option for selecting ECC mode. If any non-ECC memory is installed, the Setup option for ECC configuration does not appear and ECC operation is not available.

The following table describes the effect of using Setup to put each memory type in each supported mode. Whenever ECC mode is selected in Setup, some performance loss occurs.

Memory Error Detection Mode Established in Setup Program
	ECC Disabled	ECC Enabled
Non-ECC DIMM	No error detection	N/A
ECC DIMM	No error detection	Single-bit error correction, multiple-bit error detection

The following tables list DIMMs that have been tested. DIMMs that are not listed should also function properly as long as their specifications are compatible with the devices listed below. In general, DIMM devices that are faster than those specified for a given platform will work, although no extra performance will be realized.

Installation and use

Last known issues: Latest BIOS and drivers
Refer to the current drivers and BIOS version for the Intel® SE440BX Motherboard.

Intel SE440BX Motherboard or Intel® SE440BX-2 Motherboard
To determine which motherboard you have, refer to the Altered Assembly (AA) number or the BIOS version string.

Configuring PCI audio drivers
See the instructions for installing the Crystal PCI audio drivers in Windows* 95 or installing the drivers in Windows* 98.

Processors supported
The Intel SE440BX Motherboard supports the 450 MHz Pentium® III processor and Pentium II processors that run internally at 233 MHz, 266 MHz, 300 MHz, 333 MHz, 350 MHz, 400 MHz, and 450 MHz. Also see the additional information processors supported.

Processor considerations
The Pentium II processor connects to the motherboard through the 242-pin slot 1 edge connector and is secured using a Single Retention Mechanism (RM). Several steps must be observed when installing the retentionmechanism to ensure it and the processor stay securely attached to the board.
An active (fan) processor heatsink is recommended, because cooling requirements vary depending on the system configuration. It is the responsibility of the system designer or integrator to ensure that the processor's maximum case temperature (at the thermal plate) is not exceeded. Details on thermal considerations can be found in the Intel SE440BX Motherboard Technical Product Specification.

Will my ATA-66 hard drive work on the Intel SE440BX Motherboard?
The IDE controller integrated into the Intel SE440BX Motherboard supports Ultra DMA modes 0,1 and 2. Ultra DMA mode 2, also known as ATA-33 or Ultra DMA 33, is the highest speed transfer mode supported by the Intel SE440BX Motherboard. The motherboard hardware cannot support the maximum transfer rate of the ATA-66 drives. A drive that complies with the ATA-66 specification will run timings up to Ultra ATA-33 on the Intel SE440BX Motherboard. Please refer to the Technical Product Specification and the Motherboard Specification Update for more complete details on the various transfer modes.

Shutdown issues with Windows* 95

If you are experiencing system hangs or long delays when shutting down from Windows* 95, please try the following:

Verify that you are using the latest system BIOS.
Go into BIOS Setup, press [F9] and select 'Yes' to reset the default BIOS values
Change other Setup options as needed
Go to the Advanced menu and change the "Reset Configuration Data" entry to 'Yes'
Press [F10] and select 'Yes' to save these changes

If you are using Windows* 95, you should also verify that you have installed the Intel® Chipset Software Installation Utility into your system.

The Intel® PIIX Bus Master IDE driver also may be a factor in this issue. Contact the place of purchase to find out if this driver is installed on your system. To determine if your problem is related to the Intel® PIIX Bus Master IDE driver, remove the driver. This removal capability is provided beginning with Bus Master IDE driver v3.02. Depending on your system settings and configuration, a re-install of your operating system may be required.

If you discover that the Intel® BMIDE driver is the source of the hang or delay, there is a workaround for those using Windows* 95 OEM Service Release 2.x. To confirm that your version of the operating system contains this workaround, check your version of Windows* 95 using Control Panel -> System -> General. v4.00.950 B or v4.00.950 C (but not 4.00.950 or 4.00.950 A) have their own built-in Bus Master IDE driver. To enable the built-in Windows* 95 driver, perform the following steps:

Under Windows* 95 System Properties/Device Manager, select the appropriate bus master capable IDE device (example: Disk drives, then GENERIC IDE DISK TYPE01)
Click on the Settings tab
Check the DMA box
Click on OK to save this setting, then OK to close the Device Manager

Using the BIOS CMOS Setup, manually configure any installed ATAPI IDE devices.Common ATAPI IDE devices are IDE CD-ROMs, LS-120 floppy drives,and IOmega*ZIP drives.
