what is the highest RAM frequency for 6700hq and 6700k processor?

[jdjinn]

Hi there,

 

I was searching for information to better understand what CAS is and the importance on RAM  when I stumbled upon this document from intel:

https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/xmp-memory-for-core-processors-datasheet-20181116.pdf

 

There it says 6700hq accepts RAM with up to 3000Mhz and the 6700K up to 4300Mhz for Extreme Memory Profile. Does it mean anyone can just buy a new RAM with those speeds and the system will detect those speeds? Or is it just achievable by over- / undervolting  and overclocking?

I learnt from some years ago, that those chips supposedly wouldnt suppor DDR4 over 2133Mhz. I guess this will void any warranty but,is it worth upgrading those RAM from 2133 to those speeds shown in the document?

WITHOUT overclocking (e.g. enabling XMP), the i7-6700HQ and i7-6700K supports up to DDR4-2133.

DDR4 RAM JEDEC fail-safe standard is DDR4-2133 (yes, there are engineer regulations + standards that must be followed).

Anything over that speed is considered overclocking.

 

Overclocking anything will carry the "your mileage may vary" quote.

You MAY or MAY NOT be able to reach such aggressive DDR4 RAM frequencies...like DDR4-3600+.

The CPU's Integrated Memory Controller (IMC) might not be able to handle such aggressive frequency.

The motherboard you have paired with the CPU might not be able to handle such aggressive frequency. 

 

The document you linked to is what Intel has tested in THEIR labs.

Keep in mind, what they test in their labs may/will vary from what YOU will actually achieve.
