Acer IPIMB-AR Rev 1.02a: Comprehensive Technical Manual & Specification Guide
The Acer IPIMB-AR Rev 1.02a (often referred to as the Pegatron IPIMB-AR) is a micro-ATX motherboard frequently used in Acer's performance-oriented desktop lines, including the Predator G3620, Gateway DX4870, and Acer Aspire M1935.
Built on the Intel B75 Express chipset, this board was designed to bridge the gap between late-stage Sandy Bridge and early Ivy Bridge performance. Because it was originally an OEM (Original Equipment Manufacturer) part, finding a formal printed manual can be difficult; this guide serves as a comprehensive technical reference for pinouts, CPU support, and hardware configurations. 1. Key Technical Specifications

CPU Support List
The motherboard supports processors with a thermal design power (TDP) up to 95W. Acer Ipimb-ar Rev 1.02a Manual
3rd Gen (Ivy Bridge): Core i7-3770/K, i5-3570/K, i5-3450, i3-3240, and Pentium/Celeron Ivy Bridge variants.
2nd Gen (Sandy Bridge): Core i7-2700, i7-2600/K, i5-2500, i3-2100, and Sandy Bridge Pentium/Celeron models.
Note: PCIe 3.0 speeds are only available when using an Ivy Bridge CPU. 3. Motherboard Layout & Pinouts
For users moving this motherboard into a new case, understanding the front panel and internal headers is critical. Front Panel Header (F_PANEL)
While Acer uses a proprietary front panel block, the standard pinout for this generation of Pegatron-made boards usually follows this 10-1 pin pattern: Pins 1-3: HD LED (Hard Drive Activity) Pins 2-4: Power LED Pins 5-7: Reset Switch Pins 6-8: Power Switch Pin 9: Reserved/Empty Expansion & Internal Connectivity
PCI Express: 1x PCIe x16 (Version 3.0 with Ivy Bridge) and 3x PCIe x1 (Version 2.0).
USB Headers: Internal headers for USB 2.0 and often one 20-pin USB 3.0 header for front-case ports. Audio: Realtek ALC662 High Definition Audio chipset.
Networking: Integrated Intel Gigabit Ethernet (10/100/1000 Mb/s). 4. BIOS & Troubleshooting
The IPIMB-AR utilizes a standard UEFI BIOS. If you are experiencing boot issues or hardware incompatibility, follow these steps:
Clear CMOS: Locate the CLR_CMOS jumper near the battery. Move the jumper from pins 1-2 to 2-3 for roughly 10 seconds while the power is disconnected to reset BIOS settings. The Acer IPIMB-AR (Rev 1
Memory Configuration: To utilize Dual Channel mode, ensure you populate slots of the same color first (typically slots 1 & 3 or 2 & 4).
Drivers: Official legacy drivers can often be found through the Acer Support Portal by entering the SNID or Serial Number of the original desktop host (e.g., Predator G3620). 5. Rear I/O Panel
The back of the board provides standard connectivity for its era: Video: 1x HDMI, 1x VGA USB: 2x USB 3.0 (Blue), 4x USB 2.0 (Black) Legacy: 2x PS/2 ports (Keyboard/Mouse) Audio: 3x 3.5mm jacks (Line-in, Line-out, Mic)

For detailed diagrams and disassembly, you can refer to the Acer Predator G3620 Service Guide. Drivers and BIOS updates can typically be found by searching your SNID on the official Acer Support site. Acer IPIMB-AR - The Retro Web
I could not locate an official or user-facing manual specifically titled “Acer Ipimb-ar Rev 1.02a Manual” in Acer’s public support databases or general documentation archives. Chipset: Typically AMD 880G / SB850 (supports AMD
Here’s why, and how you can find the information you need.
Based on component and driver references found online, Acer Ipimb-ar Rev 1.02a appears in:
Chipset: Typically AMD 880G / SB850 (supports AMD Phenom II, Athlon II, Sempron 100 series, AM3 socket).
The manual is a slim, black-and-white document. It does not include a full retail motherboard manual (like ASUS or Gigabyte would). Instead, it focuses on:
The Acer IPIMB-AR Rev 1.02a manual does the bare minimum to keep a legacy system running. It is not a user-friendly guide but rather a technical reference for pinouts and basic assembly. If you own this motherboard, download the PDF – because without it, figuring out the front panel header will be a guessing game. Just don’t expect any insights into performance tuning or deep hardware diagnostics.
Recommendation: Print the jumper/header page and store it inside your PC case. Discard the rest.
The Acer IPIMB-AR (Rev 1.02a) is a proprietary motherboard most commonly found in pre-built Acer desktops such as the Aspire M3970, AM3970, and some Predator gaming towers from the early 2010s (LGA1155 socket for Intel 2nd and 3rd gen Core processors). This review evaluates the official product manual provided by Acer for this specific revision.
This is the "gotcha" with the IPIMB-AR. While the board features a standard 24-pin ATX Power connector and a 4-pin CPU power connector, Acer power supplies are sometimes built to slightly non-standard efficiency curves.
However, the good news is that the IPIMB-AR Rev 1.02A generally works perfectly fine with standard ATX power supplies from brands like Corsair or EVGA. It does not require proprietary voltage rails like some older Dell boards. If you are transplanting this board into a standard case, a generic 500W PSU will run it without issues.
The BIOS on the IPIMB-AR is the definition of "locked down."
