the good news is that I've been running them for 2 weeks at 1.63v on a 201 mhz bus (work at 1.6v as well)
somehow anything past 4039 mhz with my cpu makes the IMC voltage shoot way high (currently 1.37v,left at auto in bios)
I have the same kit with my LGA 1156 platform,and it kicks butt !!
here's my specs
i7 860@4002 mhz @ 1.28volts (19 x 210.7)
asus p7p55d evo
Kingston HyperX KHX1600C9D3K2/[email protected],nb 3792mhz,
