Question about mixing RAM

[Draydince]

I'm looking to add another 8gb to my build, and I know ideally you want to match your RAM, but sadly I'm unable to do so.

Last year I bought a custom configured pc from cyberpower (I know that word's the devil on these forums, but they had a deal that ended up being significantly cheaper than building my own)

Anyway, the RAM that came with my system seems to be something of an obscurity that I can't find a matching set anywhere: gskill 8gb ripjaw f3-14900cl9-4gbxl

I was looking at adding this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231428 but I'm concerned about the timings being different. my current ram is 11-11-11-28 whereas the newegg ram is 9-9-9-24

Would there be any significant complications by mixing kits?

BONUS QUESTION: Is there a way to disable Tomshardware from giving me a giant "DON'T TYPE IN SHORTHAND" warning every time I go to a different tab and come back? It's annoying having to wait just to see my text again ha. Anyway, I appreciate the help!

What'll happen is your ram will just run at the slower settings, not a big deal in real life. As for the bonus, I have no idea.

Thank you. Would you happen to know a way to find another set of the original ram? (f3-14900cl9-4gbxl) googling it the only results i found were for 2g sticks

All that is listed with those timings is this:

http://www.gskill.com/en/finder?cat=31&series=0&prop_14=DDR3&prop_2=0&prop_4=11-11-11-28-2N

I wonder if it is mis marked or bad SPD info in the ram ? If not, it looks discontinued and ebay may be the only place. I looked but I did not see an exact match.
