Based on the timings I can almost certainly say this is Samsung C-die. Commonly misreports as Samsung B-die in Thaiphoon Burner, so if it says B-die it's C-die as the timings are nowhere near B-die. For non-overclockers this is a great kit, for overclocking it's pretty meh and doesn't scale past 1.35V doing 3800CL18. It was $329 so… you're getting roughly 70% off!
It seems G.Skill are starting to mostly use Samsung C-die now in their 3200C16 kits, I have yet to find one on the market that isn't. The main identifier is the 16-18-18-38-56 timings, but also the model number if info is available.
$116 on staticice, far cry from $329
