well ur overclock abilities is related to the board u use, so assuming that board cant handle that lower overclock as well as the last board, maybe because lower quality of parts, the board u got, the unheatsinked vrms, but id go with a 8+2 power phase board or one with at least the vrm heatsinks. Im not sure if u wanna replace ur new board just because u lost ur 4ghz oc, but id recommend a asus m5a97 R2 or gigabyte 970a ud3 as the gigabyte one has a 8+2 power phase compared to the last two boards unheatsinked 4+1, and the asus one has the 4+2 but has heatsinks and well asus has always made quality motherboards lol
