I don't suppose you could take some pics of your bios options and post them? I still can't get ACC to work and I'm starting to wonder if gigabyte somehow turned it off for the x3's. And incidentally I was having issues running 8GB in all four slots, so after a ton of memtesting where I almost got through multiple passes stable after upping northbridge and DDR voltage, I finally decided to drop to 4GB (2x2) and start playing more with overclocking.
