BH5 regardless old or new will not work well on nF2 if you plan to run it double sided dual channel. Only works best if single sided dual channel or double sided single channel (1t Clocks Per Command drive) and you will need to mess with alpha timings. Best tool would be tictacs nf2 tweaker. I see your using an Ultra Infinity, if you need the modded BIOS (Which do help OC'ing bandwidth) PM me ur e-mail and I'll send to you my whole collection
