The Acer AAHD3-VC is a proprietary Micro-ATX motherboard commonly found in Acer Aspire (e.g., ATC-105-UR11) and Gateway (e.g., DX4380G) desktops. Because it is an OEM (Original Equipment Manufacturer) part, Acer does not provide a standalone retail manual, but the following guide covers its critical specifications and installation steps. 1. Hardware Specifications
Socket Type: AMD Socket FM2+ (supports FM2 and FM2+ processors like AMD A10-6700). Memory: 4 slots supporting up to 16GB DDR3 SDRAM. Expansion Slots: 1x PCIe x16, 1x PCIe x1, and 1x PCI slot. Storage: 4x SATA ports for hard drives or optical drives. Form Factor: Micro-ATX. 2. Component Installation Steps CPU and Cooler Lift the load lever on the Socket FM2+.
Align the gold triangle on the corner of your AMD processor with the triangle on the socket. Drop the CPU into place without force and lower the lever.
Apply thermal paste and mount the CPU cooler, plugging the fan into the header labeled CPU_FAN. RAM Configuration
For optimal performance, the board uses a specific dual-channel priority: Slots: Labeled DIMMA1, DIMMA2, DIMMB1, DIMMB2.
Priority: Install the first stick in DIMMA2. If using two sticks, use DIMMA2 and DIMMB2 to enable dual-channel mode. 3. Front Panel Header Pinout
This is the most common area of confusion since it is not always clearly labeled. If your case uses individual 1-pin or 2-pin connectors, use this general layout for Acer proprietary boards: acer aahd3vc motherboard manual install
Power Switch (PWR_SW): Usually pins 6 and 8. This is not polarity-sensitive.
Hard Drive LED (HDD_LED): Typically red/white wires; polarity sensitive (+ and -).
Power LED (PWR_LED): Typically green/white wires; polarity sensitive. Reset Switch (RESET_SW): Usually pins 5 and 7 or 7 and 8. Acer Aahd3vc Motherboard Manual - Facebook
The Acer AAHD3-VC is a Micro-ATX motherboard commonly found in pre-built systems like the Acer Aspire TC-105. Because it is an Original Equipment Manufacturer (OEM) part, a dedicated retail "manual" is not publicly distributed; instead, technical details are found in service guides or community documentation. 1. Hardware Specifications
Before installation, verify your components are compatible with these standard AAHD3-VC specs: Socket: AMD FM2.
Memory: 4x DDR3 DIMM slots, supporting up to 16GB total (DDR3-1600/PC3-12800). Form Factor: Micro-ATX (mATX). I/O Ports: Includes USB 3.0, D-Sub (VGA), DVI, and HDMI. Expansion: PCIe slots for discrete graphics cards. 2. Pre-Installation Steps The Acer AAHD3-VC is a proprietary Micro-ATX motherboard
Prepare the Chassis: Ensure your computer case has the correct standoffs installed for a Micro-ATX board.
Install the CPU: Carefully place your FM2 processor (such as an AMD A10-6700) into the socket. Lower the retention arm to secure it.
Insert Memory: Open the tabs on the DDR3 slots. Align the notch on your RAM sticks and press down until they click. Tip: Use slots A2 and B2 first to enable dual-channel mode. 3. Motherboard Mounting and Power
Mounting: Align the motherboard’s I/O shield with the case's rear cutout and lower the board onto the standoffs. Secure it with screws.
24-Pin ATX Power: Connect the large power cable from the PSU to the 24-pin header on the right edge of the board.
4-Pin CPU Power: Plug the 4-pin auxiliary power cable into the header near the CPU socket to provide dedicated power to the processor. 4. Front Panel Connector Layout No power: check PSU switch, 24-pin and CPU
The most difficult part of the AAHD3-VC installation is the front panel header (usually labeled F_PANEL or JFP1), which is often not clearly marked on the board. Use the following pinout based on community service guides: Pin Number Polarity Notes 1 & 3 Pin 1 is Positive (+) 2 & 4 Pin 2 is Positive (+) 5 & 7 Reset Switch No polarity (orientation doesn't matter) 6 & 8 Power Switch No polarity (orientation doesn't matter) 10 Missing pin for alignment
Note: Pin 1 is typically located at the corner marked with a small white square or triangle on the motherboard's silkscreen. 5. Peripheral and Driver Setup
Before installing anything, confirm you have the correct board.
Acer does not follow standard Intel front panel pinout. Looking at the board (pins facing down, label "F_PANEL"):
Pro tip: If your case uses a standard 9-pin block, use a multimeter in continuity mode to map the traces, or refer to our pinout diagram below.
It is significantly easier to install the CPU, CPU cooler, and RAM before mounting the motherboard into the case.
