I have 8GB of Gskill memory, will this 8GB package be compatible?

Model of the motherboard:BIOSTAR TZ77XE3 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS

Model of the memory:G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-17000CL11D-8GBXL

Model of the CPU:Intel i5-3570K

Newegg is running a deal on G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBRL. If I buy this, will it play nicely with the current RAM that I have? I'm not overclocking or anything. I just want DDR3 1600 to work fine.

There's always a possibility, but I wouldn't try it, even trying to set the 1333 set to 1600 you'd prob want to raise the CL to 10 and DRAM voltage up to 1.55/1.575, and to smoothly run the 2133 set at 1600 you'd prob won't a tight CL9 or looser CL8 and prob down to about 1.45 or so voltage wise....a good deal is hard to pass up, but you'd be stressing the 1333s and actually putting a load on the 2133 sticks dropping them to try and run slower in conjunction with the other
