Hi all ,

with reference to this link,

http://wccftech.com/intel-6th-generation-skylake-s-processors-officially-confirmed-core-i76700k-core-i56600k-coming-q3-2015/

Would this mean that all DDR 4 Ram above 2133Mhz will be considered useless?

Ive seen some rams claiming 2800 Mhz 3200Mhz etc, will ths be counter productive and in reality just unnecessary. Even though, the motherboard may allow you to OC the ram etc. It will still be limited by the CPU.

I hope RAM makers are aware of this Intel Skylake compability.

Please feel free to comment and discuss.

Yes, they should work precisely as they did with existing Intel DDR4 motherboards already out. The XMP profiles built into the modules' respective SPDs should allow for those higher speeds to be used without anything that would technically be "overclocking." The same goes for existing Haswell boards with DDR4 support.

There's a few ways to look at it. I might make a guess that it's referring to actual clock rate, rather than transfer rate. (which is more properly measured in MT/s) This would suggest support for DDR4-4266.

It's also worth noting that thus far, I've only found WCCFTech to mention the specific 2133 MHz as what was supported, and not other sites. This could suggest, as well, that they have incomplete information.

Lastly, and most likely, this is the exact same specification speed that Intel has tested and validated for Haswell. In other words, that means that DDR4 support for Skylake is to be identical as it is for Haswell.

no. the processors can support higher speed ram with overclocking and XMP profiles. caution: overclocking voids the cpu's standard warranty.


higher speeds are supported through XMP. more speed is never unncecessary nor counter productive. :)

as long as mobo vendors validate kits for use through QVL, compatibility should be fine.

edit:
intel and amd like to stay within JEDEC's DDR specifications for highest compatibility and stability. this is why most current intel cpus support DDR3 1600, some support DDR3 1866 ram. HEDT cpus can support DDR3 or DDR4 2133 ram. intel wants to help mainstream users pick and choose between DDR3 and DDR4 so that they can save money but opting for cheaper ram as DDR4 is new and still pricey. skylake will support both ram for this reason.
memory vendors sell higher speed ram for enthusiasts or users who'd want to o.c. their memory. those o.c. settings may not always conform to JEDEC standards, hence no assurance of wde range compatibility or stability.

To add onto what I'd said above (and also edited in) The listed DDR3/DDR4 speed is essentially identical to the existing support Intel has capped out at on their existing CPUs. So there is no going BACKWARDS or anything... Just that the situation will remain the same.

Granted, I would expect the specification from Intel to push higher as they test and work more.

So to summarize what you are saying all DDR4 speeds clocks higher than 2133mhz will work with Skylake?
