I7-4790k ram support?

[Soul slayero]

hello i have a i7-4790k and on intel website they say it can only support duel ram at 1600hz.
i want to get up to 16gb of ram that would put me at 4 sticks of ram, and also my ram is clocked at 2133. so dose my i7 not support my speed and more ram sticks?

Yes the 2133 will work fine, providing your motherboard will accept it which in 99.9% of cases it does enjoy.

Your CPU supports upto 1600 and the XMP profile will let you run higher frequency ram i.e. 2133.

how come intel says it dont support it and ill be safe getiong an other set of ram?

It means dual channel operation.
That happens with either two or 4 sticks.
If you can get the capacity you need with two sticks, that is cheaper and better.
As to speed, they are talking about the default speed supported.
You can generally use XMP profiles to go faster.
But faster speed comes with higher latency which negates much of the difference.

As to ram speeds, more trumps faster.

If you are considering adding ram, consider this:
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.
Although, I think the problem has lessened with the newer Intel chipsets. Still,
it is safer to get what you need in one kit.
