The motherboard features a dual-channel memory architecture with two physical slots.

Because it is an OEM board, finding an official, standalone manual can be difficult. This comprehensive guide serves as your complete manual, detailing hardware specifications, front panel headers, pinouts, and upgrading limitations. 1. Technical Specifications Overview

Before modifying your hardware, consult these baseline limits to prevent component failure:

Always populate the slots starting with the slot closest to the CPU if using a single module. 🚀 Compatible Upgrades

| Feature | Specification | | :--- | :--- | | | Intel H81 Express | | Processor Socket | LGA 1150 | | Compatible CPUs | Intel 4th Gen (Haswell) Core i3, i5, Pentium & Celeron | | Supported CPU TDP | Up to 84W (i7 models tested, likely up to ~88W) | | Memory | 2 x DDR3 DIMM slots, Max 16GB DDR3 | | Expansion Slots | 1 x PCIe x16, 1 x PCIe x1, 1 x PCI | | Storage (SATA) | Typically 4 x SATA 3 ports | | Rear I/O Ports | VGA, DVI, USB 2.0/3.0, Gigabit Ethernet, Audio | | Form Factor | Proprietary / Non-standard (Fits specific Acer cases only) |

: The H81 chipset does not support CPU multiplier overclocking. 3. Memory (RAM) Configuration Guidelines

The most common challenge when working with this motherboard is connecting the front case cables (Power Switch, Reset Switch, Power LED, and HDD LED). Acer prebuilts use a unified proprietary block, but standard cases use separate loose pins.

The is an OEM motherboard manufactured by Elitegroup Computer Systems (ECS) for Acer desktop systems, most notably the Acer Veriton and Aspire series. Built on the Intel H81 Express chipset and utilizing the LGA 1150 processor socket , this board is a reliable choice for budget builds, office workstations, and legacy upgrades.

If the system fails to boot due to unstable hardware configurations or a forgotten BIOS password, you must reset the Complementary Metal-Oxide-Semiconductor (CMOS).

There are two 4-pin fan headers available: CPU_FAN (located near the top edge close to the CPU socket) and SYS_FAN (system chassis fan connector located near the lower half of the board).

The best and most reliable source for the official user manual for any Acer product, including the Veriton systems that use this motherboard, is the Acer Support website. Here is the step-by-step process, as recommended by Acer themselves:

: Provides two SATA III (6Gb/s) ports and two SATA II (3Gb/s) ports. 🔌 Connectivity and I/O

: Two dedicated legacy ports for a keyboard (purple) and mouse (green).
