    Do you have the product links for each?

    It depends on the application, but generally you'll be bandwidth starved at such low frequencies so I'd definitely go with the higher frequency at looser timings.

    In one set of i5 tests I got an improvement in Minimum frames by 13fps just by going from 1600MHz 7-7-7-18 to 1866MHz 10-10-10-27 (different kits), then another 10fps from that to 2133MHz 9-9-9-24. It was only 2fps from there to 2400MHz 10-10-10-28, but another 3fps by lowering the timings back on 2133 though. I think in that setup I settled on 2133MHz 8-9-8-21 as the sweet spot.

    The main issue in my opinion is when you are CPU bound, the higher clocked RAM matters much more than the tighter timings in most situations. There are definitely some productivity situations that will be the opposite, but I didn't encounter them.

    Hi Deano,

    It’s for a laptop I picked up here as a spare, Alienware 15 i7 4710hq

    So I guess you are recomending gskill 1866

    The latency is in terms of cycles anyway.

    So if you had DDR3 1600mhz with a 7-7-7-18 setup and compared it against DDR3 1866Mhz 7-7-7-18... The 1866Mhz kit would actually be lower latency.

    Go with the higher clocked memory I say. :thumbup:

    yeah I figured that when I spotted SODIMM ;)

    I am indeed suggesting the gskill 1866 mate.


    @ Pemalite - Great link :thumbup:
