Given these chips are ATMEGA328P-PU's do I need to change the avrdude.config file or is that just for the ATMEGA328P
You definitely need 22p caps from XTALs to GN
Ok everything has been connecting except the 100uf capacitor, I dont have any at the moment (awaiting to arrive). All i got is a few 10uf.The Mega is powered through the USB serial. Correct me if im wrong.Grd is there to pin 8 (far right white wire)Current errorCode: [Select]avrdude: Device signature = 0xff7fffavrdude: Expected signature for ATmega328P is 1E 95 0F Double check chip, or use -F to override this check.

Wow, good catch. I've never seen a board with split rails like that one.I wonder how many people have been driven to the brink of insanity by those boards?
THE PROBLEM IS WITH YOUR BREAD BOARD!You have Power and Ground (RED and BLACK jumper connected to the the RED and BLUE busses on the top of the Bread board. Do you SEE the RED and BLUE stripes? DO you SEE the VOID (at pin 30) in the RED and BLUE STRIPES? Those stripes mark were the pins are connected. The VOID marks were EACH buss STOPS THERE are FOUR BLUE busses, FOUR RED busses. NOT TWO of each.Either put jumpers over the VOIDS or only connect to the Same segment.Chuck.
PU means only package type DIL (AU, PU, MUR). It is ATmega328P. Do not change config file.You definitely need 22p caps from XTALs to GND. Switch on detailed log in IDE preferences. Check your wiring. It seems to be badly connected something, broken wire etc. Also, you can check the clock signal if it is present, simply with the DMM. The voltage about 2.5V DC on XTAL1 pin indicates that it is oscillating.
