3.5 System Memory

This motherboard uses interleaved PC133 Dual Inline Memory Modules (DIMMs).
Six DIMM sockets are available for 3.3Volt (power level) registered Synchronous
Dynamic Random Access Memory (SDRAM) of 16MB, 32MB, 64MB, 128MB,
256MB, 512MB, or 1GB densities with Serial Presence Detect (SPD) and Error
Check and Correction (ECC).

The motherboard supports system memory of up to 6GB in a two-way interleaved
configuration. This configuration requires that you install identical DIMMs (exactly
the same type and size) in pairs. For example, if you installed a 512MB module into
DIMMA1, you must install the same type of 512MB module into DIMMB1. The
same rule applies to pairs DIMMA2/DIMMB2 and DIMMA3/DIMMB3.

The following table lists the DIMM socket pairs and the memory modules you can
install.

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.

3.7 Expansion Slots

W ARNING! Unplug the power supply when adding or removing expansion cards

or other system components. Failure to do so may cause severe damage to both
your motherboard and expansion cards.

In the future, you may need to install expansion cards. The motherboard has four

3.3V 64-bit/66MHz PCI slots and two 5V 32-bit/33MHz PCI slots. The slots support
PCI 2.2 protocol.

3.7.1 Expansion Card Installation Procedure

Follow these steps 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.

3.8 Connectors

WARNING! Some pins are used for connectors or power sources. These are

clearly distinguished from jumpers in the Motherboard Layout. Placing jumper
caps over these connector pins will cause damage to your motherboard.

IMPORTANT: Always connect ribbon cables such that the red stripe matches

Pin 1 on the connector . Pin 1 is usually on the side closest to the power connector
on hard disk drives and CD-ROM drives, but may be on the opposite side on
floppy disk drives.

1) IDE Connectors (40-1 pin PRIMARY/SECONDARY)

These connectors support ATA-100 IDE hard disks. Use IDE ribbon cables to
connect the master and slave devices to these connectors. If you install two hard
disks, you must configure the second drive as a slave device by setting its jumper
accordingly . Refer to the hard disk documentation for the jumper settings. BIOS
supports specific device bootup (see 4.6. Boot Menu).

NOTE: Pin 20 on each IDE connector is removed to match the covered hole
on the ATA-100 cable connector. This prevents incorrect orientation when
you connect the cables.

TIP: You may configure two hard disks to be both Masters with two ribbon
cables – one for the primary IDE connector and another for the secondary
IDE connector.
