Some questions about RAM

[Oldfishy]

I am about to build a new PC.

I selected i5 2500K for the CPU and Intel Desktop Board DP67BA for the mobo, both of which support max 1333MHz. Now does that mean when I buy memory with 1600 MHz, will it not work at all or will the system only squeeze out 1333 MHz?

For example either:

G.Skill F3-12800CL9D-8GBXL PC3-12800 / DDR3 1600 Mhz 2 x 4GB 9-9-9-24 1.5V Ripjaws X

or

G.Skill F3-10666CL9D-8GBXL PC3-10666 / DDR3 1333 Mhz 2 x 4GB 9-9-9-24 1.5V Ripjaws X


Another question: Is it exactly the same, when I buy a set of 2X4GB or exactly the same model only separately?
ie. Ripjaws X 2 x 4GB

or

Ripjaws X 4GB and another Ripjaws X 4GB of the same model


These might be some stupid questions, so apologize in advance

I use gskill ripjaws and it should work fine. But go to the webpage for Intel and check for a qvl listing for the ram. You can probably use 1600 ram, but it will only run at 1333. Haven't used an 1155 board yet. http://www.intel.com/support/motherboards/desktop/dp67ba/sb/CS-031958.htm

Intel doesn't have a ram qvl. I recommend you stick with the 1333 gskill ripjaws.

Okay, thanks for the advice.
