hello i have a i7-4790k and when reading the specs online it says it only supports duel ram at 1600hz. now dose that mean i cant have 4 sticks of ram and run them at 2133hz?
right now i have 2 sticks of ram @ 1333hz can go to (2133hz) bc i am not sure if my i7 can handle more. and would it support ddr4?
 
Solution
the i7-4790k and Z87/Z97 chipsets only support DDR3.

1333/1600 are the "supported" RAM frequencies. Anything over those frequencies is considered overclocking. Intel basically sets the support numbers just to cover their asses.

Your i7-4790k should be able to handle 2133 easily.

4790K is dual channel regardless of 2 or 4 sticks.
Generally 2 sticks is better and easier for the cpu to manage.
DDR3 only, never DDR4.

4790K specs are the default values. You can usually set the speed to anything with a XMP profile.
Your 1333 sticks are really 667 speed that gets 1333 in dual channel mode.
The intel ram controller is so good that it makes little difference what speed ram you use. More ram trumps faster ram.
You are looking at a real difference in the 2%range between slow and fast ram.
