Ram Compatibility

Hi, I am planning on building a PC in a week or so and just ordering the parts online that are on sale. The motherboard i purchased game with this RAM - http://www.newegg.com/Product/Product.aspx?Item=N82E16820231428. Was wondering if i could buy 16gb more of RAM that would be compatible with the 8gb of ram that came with the motherboard. Could i possibly get this RAM -http://www.newegg.com/Product/Product.aspx?Item=N82E16820231489 and use it with the Ram that came with the motherboard. If not, what characteristics of ram need to be similiar in order to use them together? Thank you for any responses, would be really helpful.

need to be same speed and latency, far as I know

you could prolly drop the CAS of the 16g kit to match the 8g, BEFORE you put it in

It will work but it is not recommended to use mismatched modules as it could potentially cause errors. Those modules are very similar in specifications so it wouldn't really be the end of the world to use them together but are you sure your motherboard supports 24 GB of RAM? It would be better to just buy a single kit with the amount of RAM you want or buy multiple of the exact same kit.

I guess it would support 24gb or RAM, its somewhat high endish. This is my mobo                                                                          http://www.newegg.com/Product/Product.aspx?Item=N82E16813128551&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-

Okay, yeah that motherboard supports up to 32GB. You can go for it, and it will work but if it were me I would let memtest86+ run for quite a few hours before using the computer to test stability. Then if you get errors just run it again with only the 8 GB kit and if no errors come up with only the 8 GB kit in the computer return the 16 GB kit for a refund.
