    (i7-4790k with Gigabyte Z97-D3H) Which RAM for  performance & stability (with XMP enabled): 2133MHz CL9 or 2400MHz CL10 ?




      I'm planning to build a new system from scratch

      so I'm buying an i7-4790k to install it in a Gigabyte GA-Z97-D3H motherboard.


      I'm not planning to do any overclocking to the system.

      And, specifically about the RAM I'd like to use them with XMP profile

      getting the most performance but without sacrificing stability (that's super important to me).


      So, what 2x4GB kit RAM to choose for performance and stability?


      I'm between these two:

      G.SKILL [RipjawsX] 8GB (2x4GB) F3-17000CL9D-8GBXM

      SPD: 1600MHz | 1.5V

      XMP: 9-11-10-28-2N | 2133MHz | 1.65 V


      G.SKILL [RipjawsZ] 8GB (2x4GB) F3-2400C10D-8GZH

      SPD: 1333MHz | 1.5V

      XMP: 10-12-12-31-2N | 2400MHz | 1.65V


      I prefer the 2nd one more.

      Will the system be stable with that?

      Have you tried using similar RAM with XMP profile enabled yourself?
