I have some older Patriot Gamer 2 pc3-10666 DDR3 memory (8GB) that I am hoping to pair with an i7-4770k that will be on a z87 motherboard.

Is this is a bad idea for system reliability?

Alternatively I also have G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) memory that I can use with the above motherboard/CPU...but I am trying not to, in order to save cost.
