Very nice! Glad to see it went without a hitch! Can't help you on the RAM, I don't know my way round Gigabyte BIOS, but you should just be able to bump up the ram speed somewhere. Or if there is an option, you should be able to choose XMP or something, which should set it automatically.
Also, if your CPU voltage is on auto, take it off. You can probably lower those voltages a lot and overclock a bit higher. You shouldn't need more than 1.3v. Just keep lowering it from there until it gets unstable.
