Ok guys i got an issue... I bought the above memory however its 4x4GB sticks to make 16GB... the deafult timing of 2X4Gb sticks is 10-10-10-28-1T however my ram is running the same speed 1866mhz on auto but the timings on auto are different they are 11-11-11-30-2T... Are the auto settings incorrect shall i tighten up the timings to the same amount as the 2X4GB stick or leave them memory is running 1.5v
