1.8 Expansion slots

The A7N8X motherboard has six (6) expansion slots. The following sub-sections

describe the slots and the expansion cards that they support.

1.8.1 Configuring an expansion card

1.7 System memory

The motherboard has three Double Data Rate (DDR) DIMM sockets that supports

up to 3GB non-ECC PC3200/2700/2100/1600 DDR..

1. To enhance system performance, utilize dual-channel feature when

installing additional DIMMs. Install the DIMMs in any of the following

sequence: Sockets 1 & 3 or Sockets 2 & 3 or Sockets 1, 2 & 3.

2. Make sure the memory frequency and bus frequency setting in the

BIOS are the same or set to [Auto] ensure system stability.

3. A DDR DIMM is keyed with a notch so that it fits in only one

direction. DO NOT force a DIMM into a socket to avoid damaging

the DIMM.

4. Visit ASUS website (www.asus.com) for latest DDR400 Qualified

Vendor List.

Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclusively

assigned to one function at a time. In a standard design configuration, 16 IRQs are

available but most are already in use.

1.7.1 Installing a DIMM

1. Unlock a DIMM socket by pressing the retaining clips outward.

2. Align a DIMM on the socket. Make sure the notches on the DIMM exactly match

the notches in the socket.

3. Firmly insert the DIMM into the socket until the retaining clips lock into place.
