I'd go with the Crucial Ballistix 3200MHz (BLS8G4D32AESTK) that can be currently had for £29.99 per 8GB stick, Micron E-Die IC's on it so it will do 3600MHz+ if you want to OC it.
Holy cow that is cheap. How tight can you get the timings compared to B Die?
How on earth are these so cheap?
also to add that e-die isn't some cheaper knockoff either. these briefly held the world record.Not as tight, but I've got a pair of 8GB's up to 3733 C16-19-16-16.
They are cheap, because that are made by Micron (they own Crucial) and not a third party vendor who is buying form a manufacturer, then speed binning as creaming people for most profit possible.
and >95% of performance for <50% cost of overpriced b-die gouge ram is a win in my books
