Pros: It was fast while it worked and they replace it when it breaks...

Cons: I got 16GB (2x 8GB) of this ram when I built my PC back in March of this year. By Nov. I was having random system freezes and the ram would not run at 1866. I contacted GSkill, they had me try several things and finally they determined I had one bad stick. I sent off the bad stick and got the new stick. I called and got the voltage settings from them etc and set it up at 1866.. a day later the first original stick of RAM went bad. So I have removed it and was about to email GSkill about my first stick from March going bad when my computer froze. I ran memtest86 to find out the stick I just recieved in the mail was also bad. This is horrible ram from my experience and should not have 3 sticks out of 3 one being a fresh replacement go badwhen I am using the settings they recommend in my BIOS. I am currently seeking new RAM and I am going to say forget GSkill all together.

Overall Review: I wouldn't ever buy from them 3/3 is horrible statistics on bad memory..
