I'm sure you are probably aware but the initial DDR3 P45 boards in general (not just Gigabyte) were not liking Micron at much about 1600 or so. But, there have been several new BIOS' released since I benched last which is why I need to get it going again. Let me know if any of you have good results with Micron based memory and also let me know if you start a new thread on this please Dino
