Hi Aryana, at this moment these are the only Intel® Core Processors for desktop supporting DDR4 RAM.
However, some recent Intel® Xeon Processors also support DDR4 in case you plan to build a server or workstation system.
You will need to check the SPD clock speed of the memory you have matches the supported memory clock speed for the processor you want to get.
Hi Aryana! You need to select a motherboard specification stating the work with memory at this speed, usually a series of Extreme motherboards or OC, I use X79, where the maximum speed of the declared pamiti processor 1866, and for the motherboard 2400, I had a great use GSkill- 2400 at full speed, but this requires setting parameters in BIOS (UEFI), any modern memory can work at several speeds depending on the settings.
Please let us know if you have any other questions.
Let’s bear in mind that the memory controller is now located in the CPU, so the compatibility is based on processors specifications.
I think the controller is able to detect only the type of the memory (DDR, DDR2-4), otherwise what's the point to make the memory with a frequency of 2400-3000 for DDR3 and DDR4 above 3000?
For i7-3930K frequency stated http://ark.intel.com/products/63697/Intel-Core-i7-3930K-Processor-12M-Cache-up-to-3_80-GHz (1600), but how do you explain this http://s014.radikal.ru/i329/1506/bc/6f00e38eca2d.jpg?
I am not saying it is not possible; it is just that you are overclocking the CPU’s memory controller.
The BIOS should read the SPD from the memory and operate accordingly; however, you are free to set up the memory clock speed manually or use XMP (Extreme Memory Profile) but we only recommend using the memory within the processor specifications.
Unfortunately, most computer users are not satisfied with the recommended memory speed, so the memory that is specified Aryana single processor with support for DDR4 will not be enough, we need a motherboard that has the overclocking functionality, in other words, the memory will not be able to reach their potential in the normal budget motherboard. As to the CPU, I think you can use any series i7-5*** (K,X).
