I am pleased with the ram, it came a few days earlier than Amazon said it will which is a good thing, nicely packaged, not bent or broken or anything. I've also managed to over clock it using MSI's Control Centrer and OC Genie Lite. I don't remember what it went up to, but I'm not willing to try it again as when I restarted my pc it wouldn't power back up, so I reset the BIOS, and i'm keeping it at stock speeds. Haven't had any slow downs in my programs yet, so this is another thing I am very happy with, except for the little "my pc just died moment"
