Hi, Got a new GA-P35-DS3P that wouldn't boot. Got 3 beeps, pause, 8 beeps. Would reset then repeat the beep codes. Replaced power supply, video card, RAM (3 sets), nothing worked. Ultimately the cause was the CPU. Intel Celeron D 336 that I had put on to flash the BIOS with before I replaced the Celeron with a quadcore Core 2 G0 stepping. I had assumed the Celeron was old and compatible with anything. The Celeron D 336 works perfectly fine in an older Gigabyte P965-DS3 - and it is listed on the compatibility for both motherboards.

The BIOS beep codes are very poorly documented on the Gigabyte website and owners manual. It does not even describe such a pattern of beep, pause, beep and only describes "long and short" beeps (all beeps were same length). Anyway, hope this helps someone.
