i7 6700K processor Skylake DDR4 RAM of more than 1.2V

[idata]

I read on the internet that the i7 6700K processor Skylake can be damaged if used with DDR4 RAM of more than 1.2V. The DDR4 RAM memory overclocked are all 1.35V, I think. There is risk to install, for example, a RAM DDR4 3400MHz (1.35V) with the i7 6700K Skylake? In the motherboard's specifications, it is stated that it is possible...

I don't think it is true, the memory is receiving more voltage in your example. However using XMP memory speed of 3200 will increase the CPU Vccio Vccsa voltage.

So I can install this memory (http://www.gskill.com/en/product/f4-3200c16d-16gtzb http://www.gskill.com/en/product/f4-3200c16d-16gtzb ) on this motherboard ( http://www.gigabyte.com/products/product-page.aspx?pid=5481# ov) equipped with i7 6700k Skylake?

Yes you can. All you have to do is set it to XMP in Bios to have the 3200 speed and CL timings. Here is the topic on XMP link: http://www.intel.com/content/www/us/en/gaming/extreme-memory-profile-xmp.html Intel® Extreme Memory Profile (Intel® XMP) and Overclock RAM

Hello GHMDV ,

The best way to go while using RAM is to use the tested and recommended RAM type ask per Intel's official statement here: http://ark.intel.com/products/88195/Intel-Core-i7-6700K-Processor-8M-Cache-up-to-4_20-GHz http://ark.intel.com/products/88195/Intel-Core-i7-6700K-Processor-8M-Cache-up-to-4_20-GHz

-DDR4-1866/2133 @1.2V, DDR3L-1333/1600 @ 1.35V

This recommendation is to avoid making the MCH (Memory Controller Hub) inside your Intel® Core™ i7-6700K Processor to be forced to work out of its specs. Which can lead to performance issues.

This configuration could be possible, but please take into consideration comments above.

If any further inquiries come to mind, feel free to contact us back.

I don't see the Memory Controller Hub run faster with overclocked memory. With the memory speed at 3200 Ring Max stays at 3500MHz and system agent stays at 800MHz, where does the memory controller hub run faster?

Hello wingman99 ,

The official statement from Intel is DDR4-1866/2133, DDR3L-1333/1600 @ 1.35V as per compatibility of memory for the Intel® Core™ i7-6700K Processor. Tests have been performed and it is known to work as expected within those specs.

You can work/use with higher frequency RAM and voltage, but taking into consideration it may affect the system.

I have a question does the IMC with a i5 6600k run faster than stock with DD4 2400 speed memory, and if it does what is running faster?

[idata]

Hello wingman99,

Sure no problem.What will run or work faster would be the Memory controller hub inside the CPU, after enabling XMP it can allow the system to work with higher frequency memory.

As advised above, this can reduce the lifespan of the processor and lead to issues in the future, for that reason, it is recommended to use high-quality RAM and motherboard to use XMP.

There is a list of memory modules that have been certified to work with The Intel® Extreme Memory Profiles: http://www.intel.com/content/www/us/en/gaming/xmp-for-core-processors.html http://www.intel.com/content/www/us/en/gaming/xmp-for-core-processors.html

Thanks,Esteban C

What exactly runs fast in the Memory controller hub with DDR4 2400 and i5 6600k?

[idata]

Hi,

The memory controller per se is the one being forced ("working faster") to work out of its specs while using XMP.

GHMDV, hope you can get the configuration desired in your system, if any further questions come to mind, please let me know.

Esteban C

I bought this one: http://www.kingston.com/dataSheets/HX421C13SB_8.pdf http://www.kingston.com/dataSheets/HX421C13SB_8.pdf

Thanks!

That looks just fine, thank you for sharing this information with us :)
