Alex has been clocking his DD4 RAM to 3200 Mhz for gaming. But his games keep crashing after about 10 minutes due to memory failure. Leo says that your RAM is either overheating or is defective. Get a temperature monitor program. See how hot they are running. Alex is also saying that at 3000 Mhz, he gets no crashing at all. That leaves Leo to wonder if the power supply is getting flakey.
