actually, now that I think of it... I know why now.
those two latter speeds 1218 and 1370 require you to overclock your BCLK. so that's why it's not choosing those by default. I wonder why g.skill would put those profiles there as "JEDEC" if they are not following the standard spec. (I guess it's designed to be overclocker's RAM)
so, basically... the only valid choice for the motherboard to choose at default is 1066. that's why you're getting 1066. any motherboard would do this with that RAM. you need to overclock to use the specs listed. for example, to get 685 (1370) you'd need a BCLK of 137 with a 1:5 ratio. (5x) if you set the motherboard to 137 I'm sure it would use that 685 profile by default. (or if it doesn't, just manually set it)
or you can underclock the RAM and run it at the overclocked timings. for example, 666MHz (1333) @ 9-9-9-25-34 1.50V will run fine. g.skill gives you a little extra headroom for overclocking.
but if you wanted to use the 800(1600) profile, you should use default 133BCLK with 1:6 (6x) ratio. you should be able to just enable XMP profile 1 and it will utilize the 1600MHz profile. or if XMP isn't working, just set it to 1:6 ratio (1600) with 9-9-9-25-40 with 2T command rate and 1.50V
