Need some help with my RAM?

It should work, here is a check list:

Are both the motherboard and RAM DDR3: yes

Is the motherboard compatible with the frequency(1333 mhz): yes a google search for the A55 chipset says it can handle way higher frequencys

Is the motherboard able to handle the RAM capacity: a google search says it can handle 16 gb RAM modules, so yes

Asus is a good motherboard manufacturer and they support basically all RAM sticks.

Btw the RAM stick you have right now is actually 1333 mhz not 667, DDR3 doubles the original frequency hence the name (----->Double<------Data Rate 3) I think Dylan forgot about this which is why he said it will not work. Only DDR2 and DDR1 has frequency's that low(667 mhz)

No, it won't work!!

because your motherboard used a DDR3 2250(O.C.)/1866/1600/1333/1066 MHz

this one will work: http://www.newegg.com/Product/Product.aspx?Item=N8...

your DDR3 Kingston PC3-10700 (667 MHz) won't really work as you expected but try to use it as much as you can!!

and yes, I'm 100% sure!!

~it's better to use brand new stuff than second-hand stuff~

I know that by experience!!
