Do you really mean the only way to get past 3200 is with BCLK? I've been able to get that at 100 BCLK, as have others.
Ohhps, never mind, just checked his memory:
Dominator Platinum Series — 16GB (4 x 4GB) DDR3 DRAM 1866MHz C9 Memory Kit (CMD16GX3M4A1866C9)
Tested Latency: 9-10-9-27
Actually to me, getting to 2933 MHz with those four sticks seems darn good!
