    Hey guys,

    I decided to upgrade my current hardware with an X99 motherboard and Haswell-E processor (which also involves DDR4 memory). The DDR4 memory I bought is exactly this;

    BLS8G4D240FSA, 8GB DDR4 2400 MT/s (PC4-19200) CL16 DR x8 Unbuffered DIMM 288pin

    Translated: Crucial Ballistix Sport 1x 8GB DDR4-2400 CL16

    At the moment I have 2x4GB sticks of DDR3 RAM. Is there a difference between 2x4GB of RAM DDR3 versus 1x8GB RAM of DDR4? My instinct was that it shouldn't matter, but I just wondered what you guys think. Oh and DDR4 is very expensive, buying two sticks of 8GB would have been even more awesome, but not for my money.

    Thanks.

    A bit confused..

    DDR3 is not compatible with X99.

    Secondly, you will want 4 sticks of memory. better get 4x4GB kit.

    I meant to say that I now have a Z77M board with 2x4GB of DDR3 and I'm getting a X99 board with 1x8GB of DDR4. Was not planning on installing my DDR3 on a X99 board. :D

    2x4GB vs 1x8GB; does it matter?

    CURRENT rig; check my profile info on the left.

    I'm keeping the GPU, PSU and etc.

    It matters bigtime.

    1 DIMM = single channel
    2 DIMMs = dual channel
    4 DIMMs = quad channel

    Each added channel multiplies your memory bandwidth.

    e.g. 1 DIMM could offer 15 GB/sec, two 30 GB/sec and quad channel 60 Gb/sec.

    At the very least you want to use 2 DIMMs

    2 DIMMs were basically too expensive for me to buy. Will I notice it performance-wise?

    Yes ... go with 2x 4GB DIMMs at the very least.

    2x 8GB, will that also work? Maybe I can buy a second Crucial stick.

    Of course 2x 8GB is good. But honestly if you can afford 2x 8GB .. then just go for a 4x4 DIMM kit ? That would get your the best memory bandwidth. I mean your are upgrading to X99 / Haswell-E for enthusiast class performance I hope ?

    BTW I'll write this down and prepare an article on this topic in the near future.

    It is a common misconception that you could use just one DIMM to get quad-channel activated.

    Great kit, I have used this memory in all our X99 reviews. Just flick on XMP in the BIOS and it's configured. The Corsair kits are excellent as well.

    Ok, thanks a lot. My choice is clear.

    Hey guys,

    Proud to say I bought these..

    Corsair 16 GB DDR4-2800 MHz Quad-Kit, RAM
    Corsair Vengeance LPX Series (Black)

    :)

    The availability of DDR4 is very marginal in The Netherlands. I could've also chosen the G.Skill Ripjaws 4 3000 MHz Quad-Kit, it's cheaper, but it wasn't available fast enough for me to pick them (out of stock, or week(s) waiting).

    Second reason, this:
    SRC - http://hexus.net/tech/reviews/ram/73865-gskill-ripjaws-4-3000mhz-cl15-ddr4/?page=6

    Well that's it, thanks for helping me out people!

    Was bit baffled on you picking X99 but skimming on the memory. Good you made the right choice ;)

    Yes indeed. It's delivered tommorow, so does the web shop say. :)

    Forgot to update thread. Build is stable and works great! :)

    Thanks for all the help people.

    Maybe need to test it more for stability :)bonk:), but from what I have done, it works great.
