first profile, then, is officially supported, while the second is not and instead offers a baseline of
what the memory should be able to achieve.
What's the difference between Dominator Platinum DDR4 and Vengeance LPX
DDR4?
Vengeance LPX is our mainstream DDR4, utilizing a standard height PCB and heatspreader.
Dominator Platinum DDR4 adds a larger, more robust heatspreader as well as compatibility with
our Light Bar Kit, Dominator Airflow Platinum fan, and Corsair Link for monitoring voltage and
temperature (Airflow Pro required.)
Is DDR4 backwards compatible with DDR3?
No. DDR4 and DDR3 have key notches in different places on the DIMM to prevent them from
being mixed up, and Haswell-E and X99 are DDR4 only.
Is DDR4 slower than DDR3?
Because DDR4 uses looser latencies than DDR3 does, it can be slightly slower than DDR3 at the
same clock speeds. What makes DDR4 important is that it can easily make up for that deficit by
hitting higher clock speeds than DDR3 can. Getting DDR3 to run at 2666MHz or higher requires
very careful binning of memory chips and can be very expensive, while 2666MHz is the lowest
speed we�re launching DDR4 a
What can we expect from DDR4 in the future?
We're launching DDR4 at up to 3000MHz speeds and 8GB per stick densities, but that's just this
year alone. DDR4 is expected to hit 16GB densities in 2015, allowing your X99 motherboard to
support a staggering 128GB of memory (provided it has eight memory slots). In short, it's gonna
get bigger, and it's gonna get faster.
I'm running at the default 2133MHz speed, but my system still isn't stable.
Double-check to see which memory slots your DDR4 is installed in against your motherboard’s
instruction manual. We’ve found that you have to install your DIMMs in the primary set of
memory channels first, in order, to ensure stability. If this checks out, please contact our tech
support.
