Question on RAM and cpu

[ZacharyH]

So i already have a RAM stick the Kingston HyperX Fury Blue (along with some various other parts) and I am thinking about getting an i7-6700k cpu but this error popped up when i was assembling things together on PCPartPicker:

The Kingston HyperX Fury Blue 8GB (1 x 8GB) DDR3-1866 Memory operating voltage of 1.5V exceeds the Intel Skylake CPU recommended maximum of 1.35V+5% (1.417V). This memory module may run at a reduced clock rate to meet the 1.35V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum.

Is this something that i need to be concerned with?

It's because your RAM stick is DDR3 (higher voltage), while the i7-6700K (Skylake) CPU natively supports DDR4 (lower voltage).

There were some Skylake motherboards that were manufactured with both DDR3(L) and DDR4 way back when the CPU was released then -- but to this date, everything has been DDR4 on Skylake and Kaby Lake motherboards.

My advice is to change your RAM stick(s) to DDR4, depending on which Skylake/Kaby Lake motherboard you will get. Since you are getting an i7-6700K, it's logical to get a Z170 motherboard (supports 2133, 2400, and higher than 2666MHz++ DDR4 RAM).

skylake and kabylake CPU's do not support normal DDR3 ram and would shorten or damage them if you try to use DDR3 ram with it. you will need either DDR3L or DDR4 ram if you are going to use any of these CPU's

DDR3L is just DDR3 running at 1.35V. There is no fundamental technical difference between them.

Thanks for thee info I will sell it the stick i already have to my brother who has ddr3.
I thought that only the board was the important thing that needed to support ddr3 but, THE MORE YOU KNOW
