Product introduction
Thank you for buying an ASUS® P5QL-VM DO motherboard!
Before you start installing the motherboard, and hardware devices on it, check the items in
your motherboard package. Refer to page ix for the list of accessories.
If any of the items is damaged or missing, contact your retailer.
1.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due to
static electricity
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that came with the component.
• Before you install or remove any component, switch off the ATX power supply and
detach its power cord. Failure to do so may cause severe damage to the motherboard,
peripherals, or components.
Onboard LED
This motherboard comes with a standby power LED that lights up to indicate that the system
is ON, in sleep mode, or in soft-off mode. This is a reminder that you must shut down
the system and unplug the power cable before removing or plugging in any motherboard
component. The illustration below shows the location of the onboard LED.

1.2.1 Motherboard layout
Ensure that you install the motherboard into the chassis in the correct orientation. The edge
with external ports goes to the rear part of the chassis.
Place this side towards
the rear of the chassis.
Place six screws into the holes indicated by circles to secure the motherboard to the
chassis. DO NOT overtighten the screws! Doing so can damage the motherboard.
Ensure that all power cables are unplugged before installing the CPU.
• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the
socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing,
or if you see any damage to the PnP cap/socket contacts/motherboard components.
ASUS will shoulder the cost of repair only if the damage is shipment/transit-related.
• Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA775 socket.
• The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.
This motherboard supports Intel® Hyper-Threading Technology and Enhanced Intel
SpeedStep® Technology (EIST).
1.4 System memory
1.4.1 Overview
This motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Module
(DIMM) sockets. A DDR2 DIMM has the same physical dimensions as a DDR DIMM but
has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched
differently to prevent installation on a DDR DIMM socket. The gure illustrates the location of
the DDR2 DIMM sockets:
1-3ASUS P5QL-VM DO
1.4.2 Memory congurations
You may install a 512MB, 1GB, 2GB, and 4GB unbuffered non-ECC DDR2 DIMM into the
DIMM socket.
• You may install varying memory sizes in Channel A and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• For dual-channel conguration, you can:
- install two identical DIMMs in DIMM_A1 and DIMM_B1; or
- install four identical DIMMs in all four slots; or
- install one identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow slots) and
another identical DIMM pair in DIMM_A2 and DIMM_B2 (black slots).
• Due to the memory address limitation on the 32-bit Windows® OS, when you install
4GB or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do either of the
following:
- Install a maximum of 3GB system memory if you are using a 32-bit Windows
OS.
- Use a 64-bit Windows® OS if you want to install 4GB or more memory on the
motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
• This motherboard supports up to 16GB on Windowsindows® XP Professional x64 and
Windows® Vista x64 editions. You may install a maximum of 4GB DIMMs on each slot.. You may install a maximum of 4GB DIMMs on each slot.
• The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a lower
frequency than the vendor-marked value.
• For system stability, use a more efcient cooling system to support a full memory load (4
DIMMs) or overclocking conditions.
