. Since it is an OEM board, finding a standalone manual can be difficult; you should reference the original Acer Support documentation for the specific PC model. Core Specifications Intel G41 Express + ICH7 Southbridge. CPU Socket: LGA 775 (Socket T). Supported CPUs:

The G41 chipset cannot address modern high-density memory chips. You must locate older DDR3 RAM modules that feature 8 memory chips on each side of the stick (16 chips total per module). A single 4GB stick with only 4 or 8 chips total will fail to post.

Close the plate, ensuring the lever locks securely into place.

The manual lists FSB support for 800/1333 MHz. However, it fails to document the "FSB Wall" often encountered with the G41 chipset. Through manual BIOS work (overclocking), users often find stability limits around 350-400 MHz FSB regardless of the CPU. The manual provides no guidance on the Advance DRAM Configuration sub-menu, which is critical for locking down the FSB:DRAM ratio to bypass instability.

To boot without a case power button wired up, momentarily bridge on the F_PANEL header using the flat edge of a metal screwdriver. 🔍 Troubleshooting Core System Issues
