just got my son's computer, its has the fx8350 cpu, r9-280x gpu and a gigabyte ga-970a-d3p mobo. it has adata xpg v2 4gb ddr3 1866 mhz x2 but the bios is telling me its running at 1333? i can't select the frequency to change it. the mobo states that it supports ddrs 2000(oc), 1866, 1600, 1333 with the 1866 and higher only achievable when using a am3+ cpu which the fx8350 is.
is there something i have to change to make it work or should it have been plug and play?
 
Solution
yep. sounds like the system isn't using the XMP numbers... IF that ram is even in that bios's XMP database. Just input the numbers by hand. it isn't that hard.

Thank you. Found my pc at 1600 with 2133 ram. After enabling xmp it went up to 2100.
