The board features two 240-pin DDR3 DIMM slots configured for dual-channel architecture. 16 GB (2 × 8 GB modules)

The BIOS on the Pegatron 2AD5 lacks extensive tuning options, but there are still a few key settings you can adjust:

i7-3770, i7-3770K (runs at stock speeds), i7-2600 Intel Core i5: i5-3570, i5-3470, i5-2500, i5-2400 Intel Core i3: i3-3220, i3-2100 Installation Caution

The board also uses an AMI UEFI BIOS, which is common on Ivy Bridge systems. While this is a newer UEFI, it has been described as a "locked bios of the sort that companies like Dell and HP love to use", meaning many advanced overclocking features are hidden or disabled.

One of the most significant aspects of the 2AD5 is its longevity. Because it supports the LGA 1155 socket and features a UEFI BIOS, it has remained remarkably capable well over a decade after its release. Enthusiasts today still utilize these boards by pairing them with the legendary i7-3770K processor, a CPU that continues to handle modern productivity tasks with surprising grace. Furthermore, its support for UEFI allows it to host modern graphics cards that many other motherboards of its vintage simply cannot recognize, bridging the gap between 2012 hardware and 2020s visual demands.

The Pegatron 2AD5 features a central PCI Express x16 slot for high-performance graphics card installation. Because this slot supports when paired with an Ivy Bridge processor, it is technically physically compatible with modern graphics cards, such as the NVIDIA RTX 3060, RTX 4060 Ti, or AMD Radeon RX 7600 XT.

The board is designed for 2nd and 3rd Generation Intel Core processors. The highest supported consumer CPU is the . Ivy Bridge (3rd Gen): i7-3770, i5-3570, etc.. Sandy Bridge (2nd Gen): i7-2600, i5-2500, etc..

| Setting | What to Do / How to Find It | | :--- | :--- | | | To change the boot order, press F10 during startup to enter BIOS. Navigate to the "Boot" or "Startup" tab. | | Integrated Peripherals | Use this section to enable or disable integrated devices like the onboard audio, network card, and USB ports. | | PCI ROM Priority | Located under the "Boot" tab, this setting toggles between EFI and Legacy ROM modes. Switch to "Legacy" for older OS installs or to resolve GPU boot issues. | | Enable Virtualization (VT-x) | For running virtual machines, look for "Virtualization Technology" or "VT-x" in the "System Configuration" or "Security" menu and set it to "Enabled". | | Update BIOS | Flashing the BIOS is risky. Only attempt it if the update specifically addresses an issue you are having. Updates are found on HP's support site, not Pegatron's. |

For techs and builders: the Pegatron 2AD5 typically follows standard Intel H61, H67, or B75 chipset specs.

The main front panel header is typically a 9-pin or 10-pin layout located on the bottom right edge of the board.
