Having asymmetric memory configuration between memory channels will make you lose some performance, the exact amount will vary depending on how sensitive the software is to burst bandwidth. In games, you would be looking at 3-5% worse average fps and possibly 20-30% for 0.1% lows.

Since you already have the 8GB DIMM, you can always swap one of your 4GB DIMMs out and run some benchmarks of your own to see if the loss in peak memory bandwidth performance is offset by other benefits from having 4GB more RAM.

BTW, your CPU can't overclock, so your 2400MT/s memory should be running at only 1600MT/s anyway.
