RAM timings and speeds?

I'm planning to order cheap RAM later and I noticed something that some people say don't matter but I would like some professional opinion and I know this is the place so here's the specs:

G.SKILL Ripjaws X Series 8GB
@ 1866 (PC3 14900)
Timing 10-11-10-30
Cas Latency 10
Voltage 1.5V

V.S.

G.SKILL Ripjaws X Series 8GB (2 x 4GB)
@ 1600 (PC3 12800)
Timing 9-9-9-24
Cas Latency 9
Voltage 1.5V

The 1600 is $80 and the 1866 is $70. From what I've been told at these speeds I wouldn't notice any difference but if I'm gaming does that change anything in quality or FPS drops or anything?

If it helps I'll be overclocking a fx-6300 to 4.5GHz and will be using a AMD/ATI 7950 eventually in crossfire if I can get my FX-6300 to 5.0GHz or get a 8350 in the next year (And after the crossfire bugs are fixed VIA drivers)

  1. No doubt get the 1866. Just check to make sure it is supported by your mobo. If you have issues it might run your 1866 at 1600 only.

    Where are these RAM prices from? I checked pcpartpicker and the 1866 and 1600, both CL 9 and at the same price.
  2. You should 100% get the 1866MHz, here is the review and in other hand 1866 is cheaper than 1600mhz, even they are same price. Also high speed RAM is good for your OC the CPU too.

  3. Getting the 2x4 set of ram will have you set, if you purchase the single stick it would be advised that you upgrade to a kit later on to avoid compatibility issues from unmatched sticks.

    my board won't support that speed
  7. Yes, but either you can use unclock speed 1866MHz or OC to <2000Mhz.
  8. Best answer
    The DDR3-1866 kit is a good fit for that motherboard and CPU.

    DDR3-2133 is compatible as well, but it requires some overclocking. If you do not want to overclock, you can also configure the RAM to run at DDR3-1866. So either memory kit will work just fine.

    If you need help configuring settings in BIOS, just post again and we'll be glad to help! =)

    That will be a very fast computer

    Thank you
