I am planning on building a PC and I saw that the Kaby Lake processors were out so I wondered if the i5 7600K is compatible with DDR4 3200 RAM.
Thank you for helping.
I highly doubt it. I looked at the specs and the highest speed it supports according to the documentation is 2400. Why 3200? I looked at a couple of benchmarks, such as this one http://techbuyersguru.com/gaming-ddr4-memory-2133-vs-26663200mhz-8gb-vs-16gb?page=4 Gaming on DDR4 Memory: 2133 vs 2666/3200MHz & 8GB vs 16GB | The Tech Buyer's Guru, it doesn't seem to make much of a difference, except that the 3200 cause over heating problem. Again, I am curious for technical reasons why you require a 3200?
Nice color choice, it will definitely look nice.
Please check the memory specifications for the processor model Intel® Core™ i5-7600K
Memory TypesDDR4-2133/2400, DDR3L-1333/1600 @ 1.35V
Hope it helps.
Given the specs of any Kaby Lake processor, the maximum supported DDR4 memory speed is 2400. Any memory speed above 2400 is a memory over clock. The Intel specifications for the memory controller in the processor have always been conservative. DDR4 memory at 2400 will only be at 1.2V.
As you know, there are all kinds of models of DDR4 memory sold with speeds over 2400. Speeds up to and beyond 4000 are available. DDR4 at 3200 is a moderate memory over clock for a Kaby Lake 'K' type processor. You should be able to achieve that easily with a good quality mother board, by simply using the XMP profile. The quality of your mother board and its UEFI/BIOS are factors in achieving higher memory over clocks. It is more difficult to use greater amounts of memory (16GB+) at speeds above ~3400. Using 1.35V with good DDR4 memory is standard procedure. I personally won't go beyond 1.35V, but some people do.
I use 8GB of DDR4 at 3600 with an i7-7700K in an ASRock Z270 mother board. You are not required to run your memory at 3200, by default it will usually run at 2133 with the default SPD data. Enabling the XMP profile will set it to 3200, or you can also set it manually to 3200, or several speeds between 2133 and 3200.
I also can assure you that over heating is not an issue at all. The temperature sensors in my G.SKILL TridentZ DDR4 memory at 3600 are currently reading ~25C at 1.35V. They have never been above 30C. This memory does have heat sinks on the chips, and my PC case has good ventilation.
