There's absolutely no reason not to overclock Maxwell cards, they are clocked very low and have tons of overclocking headroom. Should be able to run up to ~1515 Mhz without overvolting. You will also need to do further tuning to set PowerMizer mode, performance level, etc to ensure the most consistent performance.
Thanks for the reply epixoip. I really value the input from someone with your experience.
I didn't mean to imply I'm comparing across brute force and dict... I only meant to say that no matter what I'm trying, performance is lower than what I believe the benchmarks would suggest (using the highly scientific method of extrapolating in my head for various approaches!).
I've done the basic tuning with PowerMizer, etc... the next step is OC to see what happens. I wasn't sure how much I could safely push the cards, so your advice definitely helps. I just need to figure out how to manually set the fan speed on all of the cards before I go too far down the overclocking road. I'm using the nvidia-xconfig util to add the Coolbits option to my xorg.conf and then using the nvidia-settings tool to manually adjust the fan. Unfortunately, I've only been able to get this approach to work with Device0. Anyway, it's a work in progress! Thanks for your advice and input.
