Well the Patriot kit arrived, it's single rank unfortunately compared to DR when the SKU was reviewed in the past (2x 16GB SR), with a relatively lax 16-20-20-40, so a little gutted as in some cases I've lost 5-10% performance, but at the same time, the RAM cost less than £130 delivered so I am really not too upset; as I'd have paid another £40 or so for confirmed dual rank and slightly tighter XMP timings, and I'm not sure another 30% price, is worth another 0-10% performance (more commonly closer to that 0%) when CPU bound! Seems to be stable so far; and it's running happily at 3200MHz vs the old 2933MHz included with the machine though (which had worse CL timing also - 21-21-21-47!) so between the amount now in the machine, and the higher speed/lower NS response time; it'll be an improvement either way! 2933/21 = 139.67 3200/16 = 200 Realise that's a VERY rough scale for working out relative memory performance, but still! Can't complain for less than £130 new (and warrantied) for 32GB! Edit: Aaaand typically the kit is faulty. Memory related bluescreen and memory errors in OCCT FFS lol my luck is abysmal atm!
