* For detailed product information, please visit our website: http://www.asrock.com WARNING Please realize that there is a certain risk involved with overclocking, including adjusting the setting in the BIOS, applying Untied Overclocking Technology, or using the thirdparty overclocking tools. Overclocking may affect your system stability, or even cause damage to the components and devices of your system. It should be done at your own risk and expense. We are not responsible for possible damage caused by overclocking.

CAUTION!

1. 2. This motherboard supports Untied Overclocking Technology. Please read Untied Overclocking Technology on page 37 for details. This motherboard supports Dual Channel Memory Technology. Before you implement Dual Channel Memory Technology, make sure to read the installation guide of memory modules on page 16 for proper installation. 3. Whether 1600MHz memory speed is supported depends on the AM3 CPU you adopt. If you want to adopt DDRmemory module on this motherboard, please refer to the memory support list on our website for the compatible memory modules. 4. ASRock website http://www.asrock.com Due to the operating system limitation, the actual memory size may be less than 4GB for the reservation for system usage under Windows XP and Windows VistaTM. For Windows XP 64-bit and Windows VistaTM 645. bit with 64-bit CPU, there is no such limitation. The maximum shared memory size is defined by the chipset vendor and is subject to change. Please check AMD website for the latest information. 6. 1080p Blu-ray (BD) / HD-DVD playback support on this motherboard requires the proper hardware configuration. Please refer to page 11 for the minimum hardware requirement and the passed 1080p Blu-ray (BD) / HD-DVD films in our lab test.

The DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.

Step 3.

Firmly insert the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated.
2.4 Expansion Slots (PCI and PCI Express Slots)
There are 2 PCI slots and 2 PCI Express slots on this motherboard. PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI interface. PCIE slots: PCIE1 (PCIE x1 slot; Green) is used for PCI Express cards with x1 lane width cards, such as Gigabit LAN card, SATA2 card, etc. PCIE2 (PCIE x16 slot; Green) is used for PCI Express cards with x16 lane width graphics cards.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power supply is switched off or the power cord is unplugged. Please read the documentation of the expansion card and make necessary hardware settings for the card before you start the installation. Remove the bracket facing the slot that you intend to use. Keep the screws for later use. Align the card connector with the slot and press firmly until the card is completely seated on the slot. Fasten the card to the chassis with screws.

Step 2. Step 3. Step 4.

2.5 Dual Monitor and Surround Display Features
Dual Monitor Feature This motherboard supports dual monitor feature. With the internal dual VGA output support (DVI-D and D-Sub), you can easily enjoy the benefits of dual monitor feature without installing any add-on VGA card to this motherboard. This motherboard also provides independent display controllers for DVI-D and D-Sub to support dual VGA output so that DVI-D and D-sub can drive same or different display contents. To enable dual monitor feature, please follow the below steps: 1. Connect the DVI-D monitor cable to the VGA/DVI-D port on the I/O panel. And connect the D-Sub monitor cable to the VGA/D-Sub port on the I/O panel.

VGA/D-Sub port

VGA/DVI-D port
2. If you have installed onboard VGA driver from our support CD to your system already, you can freely enjoy the benefits of dual monitor function after your system boots. If you havent installed onboard VGA driver yet, please install onboard VGA driver from our support CD to your system and restart your computer. Then you can start to use dual monitor function on this motherboard.

EuP System

What is EuP?
EuP, stands for Energy Using Product, was a provision regulated by European Union to define the power consumption for the completed system. With the great quantity and the popularly using of the electrical products nowadays and the continuously increasing of the electrical products categories in the following 20 to 30 years, European Union decided to establish an effective strategy to solve the energy consumption problem. That is, according to EuP, the total AC power of the completed system shall be under 1.00W in off mode condition.

ASRock Instant Flash

ASRock Instant Flash is an exclusive and the most userfriendly BIOS flash utility developed by ASRock. It is embedded in Flash ROM which is used to update the system BIOS without having to enter operating systems like MS-DOS or Windows.

Features

Once executing ASRock Instant Flash, the utility will automatically detect all devices such as USB, hard disk or even floppy drive to find the exact BIOS for your system. Instead of giving you all BIOS in your devices, the Instant Flash just list BIOS versions that apply to your motherboard model only. For example, if you have many different BIOS of different motherboards saved in your devices, but you just need to flash your P45 motherboard, the Instant Flash will just list the P45 BIOS versions for you. This unique function allows you to easily select the suitable BIOS version instead of browsing through all data.
Instant Flash just list BIOS versions that apply to your motherboard model.
