i have these 2 pairs of ddr3 ram and in bios it says the ram is 800mhz , and then i went into OC in MSI bios and let the ram freqency on Auto , and its running 1600mhz which says in CPU-Z and in MSI Bios on top . does it just say that and it rins in 800mhz or what? will the RAM get faulty if i leave it on 1600mhz
