Hmm, it does seem a little high for an i5/i7. Are there still problems with running high memory voltages on these processors (from the integrated memory controller on chip)?
The range on these modules is 1.7V - 1.9V, which seems pretty high for DDR3.
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)
