4) USB Device Wake-up (USBPWR)

The jumpers are set to +5V as the default to allow wake up from the S1 sleep state (CPU stopped; RAM refreshed; system running in low power mode) using the connected USB devices. Set the jumpers to +5VSB to allow wake up from S3 sleep state (no power to CPU; RAM in slow refresh; power supply in reduced power mode). The default setting for the three jumpers is 2-3 to select +5V (because not all computers have the appropriate power supply to support the other mode).

NOTES:

1. This feature requires an ATX power supply that can supply at least 2A on the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the system does not power up.

2. The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal working conditions or in sleep mode.

3.5 System Memory

NOTE: No hardware or BIOS setup is required after adding or removing memory . This motherboard has four 184-pin Rambus Inline Memory Modules (RIMM) sockets.

These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM technologies.

IMPORTANT

1. The memory configuration of channel A (RIMMA1 and RIMMA2) and channel B (RIMMB1 and RIMMB2) must be identical (see below).

2. C-RIMMs (Continuity RIMM) must be used to complete the sockets that are not populated by RDRAMs. A C-RIMM is necessary to avoid breaking the signal lines, which are a serial connection in a Rambus interface, such as used in this motherboard. This assures the electrical integrity of a Rambus interface.

3. H/W SETUP

CAUTION! The CPU fits in one orientation

and should drop easily into place. Do not force the CPU into the socket to avoid bending the

pins. If the CPU does not fit, check its alignment and look for bent pins.

3. Once completely inserted, press the CPU firmly and close the socket lever until it snaps into its locked position.

4. Install an Intel fan heatsink.

CAUTION! Take care not to scrape the motherboard surface when mounting a

clamp-style processor fan, or else damage may occur . When mounting a heatsink onto your CPU, make sure that exposed CPU capacitors do not touch the heatsink, or else damage may occur! Refer to heatsink/CPU documentation.

NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency multiple setting is available only on unlocked processors) for your Socket 478 processor or else boot-up may not be possible. Socket 478 processors provide internal thermal sensing: a socket mounted thermal resistor is not needed.

Retention Module Base

WARNING! Be sure that there is sufficient air circulation across the

processor’s heatsink by regularly checking that your CPU fan is working. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard.

NOTE: If using a rectangular heatsink, use a model with fin-ends that project and terminate on the longer side of the unit, not on the shorter side.

Step 2: Mount the Fan

Position the fan with the retention mechanism on top of the heatsink. Align and

snap the four hooks of the retention mechanism to the holes on each corner of the module base. Carefully fit the fan and retention mechanism assembly perfectly to the heatsink and module base, otherwise you cannot snap the hooks into the holes. Keep the retention locks lifted upward while fitting the retention mechanism to the module base.

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. If your motherboard has PCI audio onboard, an additional IRQ will be used. If your moth-

erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.
