Can you mix brands of RAM?

[fireXtract]

It has probably been asked before but i want to make sure these types of ram will be compatible...

Newegg.com - CORSAIR XMS3 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMX8GX3M2B1600C9 at timeings of 9-9-9-24 at DDR3 1600

and this AMD branded ram
Newegg.com - AMD Entertainment Edition 4GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model AE34G1609U2 at timeing of 9-9-9 and 1600
I would probally buy 2 of the AMD ram or is there a better option?

Any feedback is appreciated!
PS: i live in america so it would have to be at newegg.com not .ca

yes but size are differrent amd is one stik 4gb and corsair is 2x4gb stik of 8gb for dual channel mode if MB supports it

also check your MB spec's on total ram

[techman95]

it could if you had the timings, amount of ram on dim, and voltage the same. i would not buy that amd ram b/c it is loose timings, rather high volts, and well cheaply made. i would just go with another set of xms3 i have two kits of that and love it

Thank you i saw it on sale and i wanted to see if it was worth while. SO thank you again and you said to just go with another kit of XMS3?
Also can i ask what the timings on RAM are about?
If there is a ram with
9-9-9-24
9-9-9-24n
and 9-9-9
what are the differences and what to the numbers mean?
