I recently installed the Corsair Dominator Platinum 16GB (4x4GB) DDR4 PC4-29000C18 3600MHz Quad Channel Kit - Silver (CMD16GX)

My CPU is an i7 6700K on Intel's spec page it states

"Memory Types - DDR4-1866/2133, DDR3L-1333/1600 @ 1.35V"

Does this mean in my XMP profile I need to set the DDR4 speed to 1866/2133 at 1.35v just to have the basic designed speed/setting for this RAM?

The Ram states 3600Mhz - I presume that's its MAX OC'ing potential.?

excuse the stupidness, I'm new to XMP/OC'ing etc.
 
Usually out the box the Memory will run at lower clock speeds, normally 2133 Mhz and that will be at 1.2 volts or something there about by default IIRC

XMP is a profile that comes with the memory that ups the voltage to 1.35 volts usually and changes some timings to get things running at 3600mhz. Usually XMP is a simple matter of going into the BIOS and selecting the pre-made profile with the kit.

The ram stating 3600 Mhz means its been screened to work at that frequency. You could in theory manually push things a bit further, but essentially the XMP profile has been set up for 3600 Mhz.

One thing to keep in mind, its not independent and in part depends on your motherboard and CPU's Internal Memory Controller (IMC), so getting 3600 Mhz may not be possible if you got a poor IMC.

I suggest easiest thing to try, go into BIOS, enable XMP and see what happens

thanks I enabled XMP and left everything as default/auto.

Boots into windows 10 but its getting stuck now and again when doing anything freezing for few ms then fine?
 
As your board looks solid, its heavily dependent on the quality of the memory controller on your CPU.

I have just completed 3 days of testing with a few DDR4 kits on my new 6700k rig.

What I would do is start at DDR4 3000 with default volts on everything. Once you hit around DDR4 3400 you will more than likely need to increase the voltage on the CPU memory controller and possibly the PCH bus. These settings are VCCSA and VCCIO. I needed to raise them both to 1.1v to get beyond DDR4-3400, I cannot get beyond DDR4-3700 on my CPU and MB. The peeps getting DDR-4000 on the 3600 class kits are running 1.26v on the CPU memory controller (VCCSA) and 1.2v on the VCCIO.

I would strongly recommend not using XMP and manually entering the values in the bios for the timings but granted, this takes time and research to do.

The litmus test will be the Intel XTU benchmark (free download), don't bother with the RAM stress test tool on it, the benchmark test is the one you need.

Typically 3600 requires in excess of 1.2v VCCSA for stability, you can set IO voltage to the same as this. Also might be worth updating the UEFI as Stulid has suggested.

Test memory stability with HCI Memtest Pro. One instance per thread covering 90% of memory. The Formula will be great with 4 sticks, but 16GB at 3600 may require some tuning as in the former part of this post.

It takes 1.2 and 1.15v on vccsa and vccio respectively to get my dominator ram to run at 2800 mhx even though its rated at 3200. You'll be lucky to get yours running at 3600. You can push the imc up to 1.35v apparently and my xmp profile does set yhis value but i just cannot boot
