Here is also how CPU-Z and AIDA64 see the Crucial memory. As you may notice, there is no XMP profile but it is not required as the memory is working at standard SPD profile of 2133 CL15. More details can be seen in the attached screenshots.
The memory arrived from Crucial in four, single stick blister packs. Each of them has exactly the same product numbers so we can use them as a quad channel kit.
The standard packaging is good enough to protect the memory for the duration of transport. We can also see the most important information on the label like basic memory specification, capacity, declared frequency and voltage.
It is hard to say something about the design except that we see a standard looking memory module not much different than DDR3. There are little changes in number of contact pins, 288 instead of 240. The modules are also slightly thicker in the center than on the sides (hard to see that on the photos). Maybe this is to create an easier installation.
Micron used a standard green PCB to build their DDR4 memory. It does not change the fact that the modules are good quality even though we cannot see anything additional like heatsinks. DDR4 does not really need heatsinks as it is not generating much heat. Speaking about heat, the memory chips used here are the Micron D9RGQ, which are specified to work up to 95°C which is more than any consumer DDR3 can stand.
This Crucial DDR4 is based on the already mentioned Micron D9RGQ. The utilized IC is specified to run at 1066MHz (DDR4-2133) and CL15. The maximum voltage for our modules is 1.26V during normal workloads, but the absolute maximum at which they can work is specified as 1.5V. It is not recommended to use such a high voltage for daily work; however it is good to know that there is some headroom in case we wish to overclock it.
