An eBay seller included an unverified manual claiming the board supports 8GB of RAM. The verified manual clearly states 4GB max (due to the NVIDIA MCP73 memory controller limitation). The buyer wasted money on 4GB sticks that wouldn’t POST.
was a workhorse for mid-range desktops in the late 2000s. It supports processors using the LGA 775 socket. Its primary constraints stem from its OEM nature:
Move the plastic jumper cap from to Pins 2-3 (Clear CMOS) . Wait 10 to 15 seconds. Move the jumper cap back to Pins 1-2 .
The board will install using generic Microsoft WHQL drivers. However, the legacy onboard GeForce 7100 graphics processor does not have official Windows 10 drivers. To run a modern OS smoothly on this motherboard, installing a dedicated, low-power PCI Express graphics card (such as an NVIDIA GT 730 or GT 1030) is highly recommended. acer mcp73tad motherboard manual verified

Once you have the correct, verified document, here are the most critical sections you need to bookmark:
Because it is an OEM board, it lacks a traditional retail manual (such as those provided by ASUS or Gigabyte for consumer boards). Instead, documentation is typically limited to the "User Guide" provided with the computer tower or service manuals found in Acer’s corporate service channels. This report aggregates verified specs and functional details.
Because this board is from the LGA775 era, finding a manual is crucial for upgrades or repairs. 1. Verified Technical Specifications (MCP73TAD)
