I'm not certain that this is precisely the kind of feedback that you are hoping for, but my current RIG has provided me with my first experience with mixing RAM and I thought I'd share. I too have always heard the definitive explanation that one can not expect to mix and match RAM sticks with modern DDR 3 MOBOS. Unfortunately, when I bought my first Z77 MOBO (a Maximus V Extreme), I could not get more than 1 stick of RAM to run, no matter the configuration. Turned out it was a faulty MOBO, but before I realized this I managed to buy/trade for a total of 5 Dual Channel Kits. So when my lovely Girlfriend surprised me with a brand new Maximus V FormulaTFX, I very much wished to somehow make use of more than just 1 of these RAM Kits. Turns out that the experts who say you can't mix RAM are... quite right! At least for the most part. Out of all of the possible pairings of my 5 Kits, I was only able to get one such pairing that would both Boot and run at speeds beyond 1600MHz. My Dominator Platinums 2x4GB 2666 CL11, and my G. Skill RipJaws Z 2x4GB 2400 have been happily co-habitating at speeds up to 2600 MHz with very loose timings and 1.78v. But I run them at 2447MHz with 9-12-11-31 CR1 and a Latency Boundary of 5, which on my MOBO is the setting which determines how tight one's tertiary Timings will be and 5 is pretty damn tight! I can manage these settings with 1.75v, and the Bench scores in Apps like AIDA64E are much higher than 2600MHz w/ loose timings. I consider myself to be lucky as hell to have purchased sticks which can mix like this, especially since they use different ICs. They are very stable, and have been by far the easier half of my Overclocking effort with this generation of tech. I hope this is of some use/interest. Be well!
