For the chipset to be able to address memory like this they have to be identical in terms of not only speed but also model and make etc. The "system" sees the two or three RAM sticks as one bank of RAM memory.
On a X58 you have two sets of triple channel memory slots. That's why the banks have two sets of color coding.
You don't need to match your new set of RAM sticks with your existing ones in terms of make and model.. The new set should be matched though so that you can run them in triple channel as well. The bus can not run individual frequency to the different banks, so all memory must run on the same speed and with the same timings. So your "worst" RAM stick will set the mark for all other..
So if i'm getting this correctly, i can buy 3 identical sticks that match each other but don't need to match the previous 3. Then i will have to downgrade my faster set to the speed and timings of the slower one.

Thanks for the input
