Agreed, i had 16gb of corsair vengeance lp. It even made clocking the cpu alone a bit trickier. Dropped down to 8gb, cpu clocked fine to 4.5ghz, the vengeance lp wouldnt clock diddly squat, it needed 1.575 vdimm to do it's rated 1600mhz 9-9-9-24. Sold the remaining 8gb and got some sammy green, 2133mhz, 9-10-10-22 with a little bit of tweaking, same voltage as the vengeance.That memory is not designed for overclocking mate. So I would just leave it at stock as timings would need relaxing too much to be worth it.
