I have no complaints with the deluxe5 except the bios still need a little work. It is almost the same as my deluxe3. I am running at 4mhz/ fsb at 200 / mem set to xmp profile 7/8/7/24/40. these are g skill eco ram at 1.35 volts. 1090 voltage set at 1.4125 and will run with llc 1.46. mem and cpu volts are lower than the deluxe 3. The problem i have now is when i set the fsb to 250 mem volts must be set to 1.475/ cpu nb volts 1.3 I can still run prime stable at 4mhz same as the deluxe3 at fsb 250. The bios will hold my settings when i adjust them and continue. When i shut down and start up it does not like it and will default the cpu to 3.2 mhz. restart and enter bios exit and save back at 4mhz. I have not found a way to solve this problem. May need bios update or i am missing a setting when I adjust. All in all i would rate this board very very good. If i was to buy another board today it would be a deluxe5 or in the future a deluxe6.
