After purchasing a motherboard, I noticed that pcpartpicker noted that h81 motherboards may need a bios flash in order to use Harwell refresh cups. However, i read that people said the bios is already updated and a flash will not be required in order to run my CPU. I ordered my motherboard in December of 2015, so I do not know whether I need to update my bios using a Has well processor in order to use an i5 4460. If anyone can tell me that would be greatly appreciated!
