UD5H or UD5H..jk all this boards are great ,i have UD5H,UP7,M5G and i just recently sold OCF which i enjoyed very much,out of all of them i would say UD5H is the best bang for your buck and very nice 24/7 board and then some ,for RAM clocking i use M5G and UP7 will go under cold but needs more time for bioses to mature ,..couldn't keep OCF as it was just to bulky but the board was great
