I just got a new R5 1600 and installed it on my Asus Prime B350M-K motherboard and whenever I try to set the multiplier to higher than 35 and save it the pc reboots at 35x only. Also my voltages are pretty high, I get 1.388 at 3.5 GHz and my peak temps are 75C. My PSU is Corsair VS550 and 16 GB DDR4 at 2666Mhz. Should I get a refund?
