    Default 2 or 4 Sticks of Ram and Does It Matter?

    Whether I pick 8- or 16GB of RAM, should I use only two channels or all four or does it even make a difference?
    Thanks!

    It can make a difference if you're able to bottleneck a dual channel setup. But in all honesty, it's really hard to gauge. You could see about a 10% gain if you were using something that was highly dependent on RAM or doing a ton of multitasking, but for something like a video game, you'd see a marginal if not negligible difference. I'd say for right now, just get the best 2x4GB, 8GB dual channel setup you can get your hot little hands on. And if you feel the need to get 16GB in the future, then you can always stack on two more. As it is right now, I'm able to run a crossfire eyefiniti setup with 5760x1200 resolution, do photoshop, lightroom, play any game on highest settings and am still not bottlenecked or even at limit of my 8GB of ram. I don't do any video editing, so results may vary.

    You don't state what speed in Mhz the ram you're looking at or considering.

    If you're OC'ing that 4790k and looking at above the 1600Mhz ram the IMC is rated,, then I'd say two sticks. If only to keep a 4 stick OC'd load off the IMC.

    #3 - Please use the eXtreme Outer Vision Power Supply Calculator found HERE to determine if it might be your PSU at issue.
    ____Consider your PSU to be the foundation from which all else is built upon. Anything built upon a weak foundation is poorly built.

    Thanks!
    Your i7-4790K's memory controller is only a dual/two channel controller. Your Z97 board has four memory slots for DIMMs, two per channel.

    Your question is still valid, you would think using both slots in one channel would be better than using one slot, given twice the connections to the DIMMs. EmptiMind may be right about the difference being minimal, I don't know either way, which you just made me realize. I must check that out, more later...

    For overclocking, less memory, less stress on the IMC.
