Your CPU, i7-860, is faster than 2.66GHz so it can handle DDR3-1600 with not much if any problems.
Memory Bus Frequency Mode -> (16 or DDR3-1600MHz)
Memory Remap Feature -> Enabled
DRAM Command Rate -> 2 (same as 2T or 2N)
Configure DRAM Timing by SPD -> Auto ; if CPU-z CAS Timings are wrong per Corsair spec change
DRAM Voltage Setting -> Auto ; IF RAM is 1.65v at Rated -> 1.65v or closet menu value
CPU VTT -> Auto ; problems use 1.20 (1.50v RAM) or 1.30v (1.65v RAM)
