so i recently bought a 16 GB DDR 4 3200 CL 16 RAM and when i installed it it says at the bios that both RAMs are 2133 mhz (intead of 3200) . So i did a bit of a research and did something with XMP . I set it from auto to a Profile (XMP 1) which i set this profile to the 3200 Mhz Speed( There are lots of speed options). And after a restart i opened BIOS setting again and yes it worked, it says that both RAM ( dual Kit 2x8GB ) runs at 3200 mhz) so my question is am i doing the right thing? i dont wanna break my PC. And second question is , i monitored my PC since i install the new RAMs just incase something might happen with the other parts and i noticed that my PC is only using 50 Percent of the RAM the whole time , altough i launched game like GTA V, is it normal here or is there a setting so that i can use more than half like at least 75 - 85 percent of my Total RAM?
