To sum up, if you want the coolest modules on the block and you're feeling flush, the Corsair Xpert is in a niche of its own. Paired with Samsung's TCCD modules, there's a world of performance to be had from them at modest Vdimm. Otherwise, the G.Skill and OCZ both come recommended at around the £200 mark, with Corsair's XL PRO and XL PT under that price, too.
