Integrated ATI Radeon X300-based graphics with shared memory Audio: Realtek ALC888 8-channel High Definition Audio
The is more than a dry technical document – it is a key to keeping a reliable, vintage AMD platform alive. Whether you need to decipher a beep code, connect a new power supply, or overclock (minimally, via BIOS, though the manual discourages it), this guide and the original PDF will give you the confidence to work on this classic motherboard.
While not in the manual’s specifications, a critical piece of advice for this board: The RC415T-AM was manufactured during the infamous “capacitor plague” (2004-2007). The manual does not mention this, but if your board is unstable, look at the cylindrical capacitors near the CPU socket. If the tops are bulging or leaking, you need a recapping service, not a manual. rc415t-am motherboard manual
