I am wondering if it is okay to install memory modules of different capacity (e.g., 2GB + 4GB) on 770 Extreme3 together. Assuming the memory modules are from the same vendor and have the identical RAM timing latency, and I don't worry about the Dual Channel Memory setting as well. Furthermore, if it is possible to install a 2GB and a 4GB memory modules together, should the modules be installed in the same color memory slots or in the different color memory slots?

Thanks
