The Guru of 3D published a review on the Teamgroup T-Force Night Hawk 3000 MHz 16GB Dual Channel DDR4 memory A quote from the article:

We review a 16GB DIMM DDR4 memiry kit, the T-Force Night Hawk 3000 MHz CAS16 DDR4 memory from Teamgroup. It is high-frequency, it has animated LEDs and runs XMP 2.0 memory profiles on Intel platforms as well. Join us as we review some of the nicest looking DIMM bars of memory your money can get you.

DDR4 memory modules you can choose plenty from, the cheap but dull all green Kingston Value memory for example works absolutely fine. Then the regular mainstream DIMMs, then step it up a little and say high-frequency memory is a hint faster and often cooler looking inside your PC with the fancy designs and heatspreaders. Then there's enthusiast grade memory for the performance enthusiasts, which is what we will look at as Teamgroup has released T-Force Night Hawk memory. The DIMMs we received from them clock in at a 3000 MHz (effective), considering that a lot of you run your memory at 2133 MHz and for DDR3 actually 1600 MHz, that's nearly double the memory frequency. But how will that relate to performance?

Stylish RAM memory for the people that need fast performance, the people that build their own PCs, perhaps customize it a little. In that mindset Teamgroup released an updated SKU based on quality, performance and aesthetics as the T-Force Night Hawk have LEDs that animate.
