I recently purchased some 3200mhz ram, mainly because i wanted to upgrade from 16gb to 32gb, but I thought at the same time it was worth getting a decent speed upgrade. I didn't realise until I installed the ram, that my motherboard only supports a max of 2400mhz. Will the speed difference between 2400 and 3200 make it worth buying a new motherboard, or is it negligible?
