Can i use G skilled Ram with 3200mhz frequency to i7-5820k?

[Dagzz]

i am building new pc so my config are
i7-5830k
x99 deluxe 2 mobo
G skilled 2x8gb (3200mhz) ddr4
1tb hdd
GTX 1060
dual tower air cooler

Again my question is Can i use G skilled Ram with 3200mhz frequency to i7-5820k? beacuse i came to know that i7 5820k support only 2133mhz or lower
but now i got the Ram which is 3200mhz
So what to do ?
please help

You would be leaving performance "on the table" because that CPU is a quad channel memory CPU and you are only giving it half memory bandwidth. Get a matched set of 4 DIMMs for maximum performance.

You don't provide a part number for the G Skill RAM, but for instance look at this page on G Skill website -- http://www.gskill.com/en/product/f4-3200c14d-16gvk Notice that the SPD shows 2133 -- The DEFAULT speed for that RAM is 2133. The MAX tested speed is 3200.

You may be able to run 3200mhz ddr4 with your i7-5820K, but I wouldn't recommend it though. Normally it'll require a blck change to 125mhz, a voltage increase and not all Haswell-E processors can run 3000+ memories.

Generally most people use 2666mhz as max, as it will stay within the blck 100mhz limit and there's not much to be gained above it. See this thread

To have the fastest system you need 4 sticks of ram to take advantage of the quad channel memory system. Four sticks in quad channel at stock 2133mhz runs faster than dual channel at 3200mhz.

I suggest you read some of the oc guides or reviews on Haswell-E, they are quite usefull. And most importantly don't mix up Haswell-E with the skylake or Broadwell-E as they run on a different architecture with different voltages and oc settings.
