So I recently built a new computer, and have parts lying around, my dad came and asked me if he could use my ram since it's not being used at the moment. I went and checked and he has 3000 Mhz ram and I my old RAM is 3200 Mhz, they're both Corsair Vengeance LPX so would it be possible to underclock the 3200 and then he can have 32gbs of ram?
