Sort of. If the RAM doesn't clock well at all, then you can always go 2:6 on the divider for 1333 ram. This would make the max Bclk = 222 (or up to 4.4+Ghz), which is more than enough for the OC you are shooting for. If you want the normal 2:8, then 1600 RAM is better for the 200 Bclk.
There's always been the debate on latency versus speed, so I won't get into that here.
