OTyur, Thank you for posting in the Intel® Communities Support.
Just to let you know, we only provide support in English language and currently, we are using a translation tool.
In reference to your question, the memory controller is integrated into the Intel® Core™ i7-5930K, so the processor is the one that indicates what will be the proper memory RAM configuration to use.
The proper memory RAM for this unit is DDR4 1600/1866/2133 and the processor Base Frequency is 3.50 GHz and it can reach up to 3.70 GHz when Max Turbo Frequency gets activated, which is something that is done automatically. Please verify the next link to confirm that information:
If you modified any of the frequencies described above that will be considered overclocking and altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance. Product warranties may not apply if the processor is operated beyond its specifications, as you can check here:
