Which is what the kid gave me. and that what I was attempting to get my ram set at! So i'm off to return the ram tomorrow morning. Is it worth it to get the 1866 its only like $30 more. Oh and thanks soooooo much for the assistance !
That's not how it works. Most likely your RAM is truly 1600MHz with an XMP profile for 1866. XMP profiles are for intel CPU's. XMP = xtreme memory profile.
First we need a little bit more info about your rig. For instance, what is your CPU-NB frequency? That has every bit as much of an affect on your what frequencies and timings you can pull from your RAM.
Secondly, unless I am mistaken, AMD rates all AM3 CPUs' RAM frequency to 1333MHz. Regardless of what the RAM is rated for AMD only officially
says that your RAM max frequency is 1333MHz. So when you're trying to run it at 1600, you're technically overclocking it.
Third, what is the exact part number for the RAM that you bought? This will help in determining what your sticks are capable of.
Fourth, you can't simply just set your RAM to 1600 and expect it to work. If you do not do any stress testing expect that you will start to get crashes and operating system corruption will soon result as memory is the only thing that can corrupt an OS.
