You may have a weak IMC but I would say your biggest problem is the Gigabyte MB and it's crap BIOS.
See if you can find someone who has posted a high frequency RAM OC on that MB and try copy there sub timings exactly.
To find out if the RAM is faulty test one stick at a time if one stick can hit it's rated speed and the other can not you know you have a dud.
