RAM Help.

Recently I've been slowly choosing my components for my next build.
When I came across RAM I noticed there's a few different specs I hadn't taken into consideration.
These specs include the Latency (8-8-8 and 9-9-9), voltage is also a new spec I noticed (1.5V, 1.65V and 1.35V) and another thing I noticed was that some RAM say different Motherboard Chipsets, and I'm getting a Z77 motherboard and because its rather new not many RAM's include that chipset, does the chipset matter and can you explain Latency and what voltage does.

Thanks alot.

  1. Ivy Bridge is OK with all 3 voltages.

    The lower it is, the cooler the RAM runs.
  2. CAS Latency: Time between the CPU asking for data and RAM releasing it.


    Technically, lower RAM timings are better (example: 8-8-8-21 is better than 9-9-9-24). However, with modern processors the performance increase isn't really worth the cost unless you absolutely must squeeze that last percentage point out of your system. Get the less expensive CL9 RAM and spend the extra on something that matters (for a gamer, that would be a better video card or processor).

    Higher RAM speeds are better (example: 1600 is better than 1333). However, that's true only up to a point. Once you get up to 1866 or so, the timings have to be so loose (so much higher) that there's very little performance improvement.

    Right now, I usually recommend 8GB of DDR3-1600 CL9 RAM for dual-channel systems. If you're getting triple-channel, then I recommend 6GB of DDR3-1600 CL9 as a minimum.
  3. Are u getting the Ivy Bridge CPU?

    Sandy Bridge like 2500K or 2600K needs 1.5V or less.

    Im getting an Ivy Bridge CPU. I want to get 8gb DDR3 1600mhz, but I wasnt sure what difference the latency and the voltage made.

    I'm getting an AsRock Extreme 6 Z77 with an Intel i5 Ivy Bridge 3570k.

    Can you give me a suggestion on a low clearence RAM (so it wont hit the CPU cooler) or least confirm that voltage doesnt matter for my components.

    Greatly appreciated

    I would get one like this and run it @ 1866MHz without any problems : )
