Hey guys, I just purchased some more RAM because I wanted to finally get more then 4gb. I read multiple things that I could use a 1600mhz stick even though my motherboard is saying only 1333mhz. I went in to my BIOS and did the XMP thing and adjusted it to use 1600mhz and upon restart it brings me to a screen that says overclocking failed. So, I just turned it back down to auto just to get it to work. Also, I'm using two different brands of RAM, 1 set is 1600mhz while the other set is 1333mhz, and one is 12800 and the other is 10700. I cannot seem to find an exact answer, some people say this is ok (with setting changes) others say don't mix and match. I'm going to attach some CPU-Z images, and was hoping for a good discussion on what should I do to achieve the best results (although, I don't want to go overclocking crazy because I can't afford anything to screw up.)
