RAM question


I'm looking to pair dual-channel RAMs on my i5-200k and ASRock Z68 Extreme7 Gen3.

I was looking at the Corsair Vengeance 8gb 1600hz or the G.Skill Sniper 8gb 1600hz 1.25v.

A friend told me the i5 is only compatible with "DDR3 - 1066/1333" ? (I looked at the intel site and it said the same thing). Is this true? What are the consequences of putting RAM with higher Hz?

If I'm stuck with 1333hz, then I'll be going for the Corsair XMS ones. Are there others I should be looking at?

  1. Ok, I answered my own question :D

    Searched around a bit.

    I'll go with a G.Skill Sniper 8gb dual-channel 1600Hz 1.25v, and just OC the CPU.

    Edit: The mobo doesn't support this... damn.
    I'll be getting a G.Skill F3-10666CL9D-8GBXL, 1333hz 8gb 1.5v

    You don't NEED to overclock the cpu on a Intel system to run your ram at 1600mhz.

    You simply set in bios your ram speed, voltage and timings manually. It will likely default to 1333, but 1600mhz ram is the performance sweet spot for s1155 cpu's. So you want the 1600's.

    Just make sure your dimms are 1.5v or less.

    You deserve a gold medal.

    Please i don't care if you are overclocking or not. Get 1.5v ram. Save the headache.
    Anymore than 1.575 is too much stress on the CPU.

    These two are great choices,
    Mushkin 1600 1.5v 8GB Kit
    Kingston 1333 1.5v 8GB Kit

    I would pick;
    CORSAIR Vengeance 8GB Kit 1.5v

    Btw i strongly think 1333 does not make a big difference between 1600. But the corsair vengeance is the best because of the low voltage and high speed.

  5. Ah.. ok, thanks guys.

    I've had a look at my motherboard, ASRock z68 extreme7 gen3.

    The ones xPanda listed aren't compatible on the list given at the site :( The one listed at the ASRock site that I've decided on is G.skill F3-10666CL9D-8GBXL

    Unless I can use those (the ones xPanda listed)? :D

    So... just to clarify, I can just use a 1600hz ram, and manually adjust TO 1600hz?

    Yes if you are not overclocking your CPU much.

    No if you are overclocking your CPU a lot, the RAM might go unstable.

    Honestly i wouldnt buy G-skill though, there cheap for a reason.
    Go for a reliable brand.


    But that, IMO is better, but you can get away with cosair, crucial, mushkin ect.

    BTW the ASRock Company can't test EVERY DIMM on the market but if you want to play it safe, go crazy.

    For Gskill i would get this,
  7. Ah.. ok, thank you :D

    G.SKill is cheaper, but I've been told by comp builders that they've got problems.

    I'll go with your suggestion of that Kingston RAM.

    Thank you :D
  8. No matter if your overclocking or not, manually set it to 1600mhz.

    I really don't pay attention to memory QVL's anymore. If the memory is the right speed and voltage it will work 99% of the time.
  9. Ok, cheers :D
  10. If I were you I'd spare the headache and let it at 1333 mhz... On my GAMING pc the motherboard supports maximum 1333 and although I have kingston ram which are capable of 1600, I left them at 1333 and it works like a charm.
    Best of luck.
  11. Ah, ok.

    cheers :D
