Does memory make a difference?

Given everything equal:

Intel Core™ i7-2600K Processor
Asus P8Z68-V PRO Motherboard

does putting in the following memory

PC3-12800 DDR3 1600 (16GB)

vs

PC3-10600 DDR3 1333 (16GB)

really make a difference?

  1. Not a massive realworld one no, but overclocking headroom is obviously higher

  2. Memory has no relation to overclocking the cpu.

    The sweet spot for Sandy Bridge is 1600mhz ram. So that is what I would recommend getting.

    Would you notice a difference? No. But 1333 @ cas8, is pretty much just as fast as 1600 @ cas9.

    Just make sure whatever you get is 1.5v or less.
  3. I meant for pushing the ram Geek, not clocking the cpu

  4. I just said that so you didn't confuse the guy.
  5. Thanks for the responses. I was asking because I can get the PC3-10600 DDR3 1333 (16GB) for quite a bit cheaper than the PC3-12800 DDR3 1600 (16GB) . Both from the same manufacturer.

    Not that I'm cheap, but if I'm not really going to see a difference, and I have no over-clocking intentions, I would just buy the cheaper memory.
  6. no problems then :)
    cheaper and sufficient, you win hehe
    @Geek np man, it just reminded me to post more complete advice mate so thank you :)

    Well you can't just look at the speed, you also need to look at the timings. A cas8 1333 would be as fast or very close to cas9 1600. You also want to make sure you get 1.5v ram, not 1.65v for that cpu. If they are both cas 9 and the 1333 is $10 or more cheaper, go for it. If the difference is $5, I would get the 1600.
