The thread hyped my curiosity to run the benchmark. I read the "do's and don'ts" at the beginning, saw no prohibition on tweaked clock settings, and went forward with the screen capture using settings established for stress-testing the SLI setup.
This is not the sig-rig, but a twin with these specs:
i7-2700K @ 4.7 Ghz with 16GB DDR3-1866
2x MSI GTX 970 Gaming 4G cards:
core clock: 1468
memory clock: 7500
I don't have a 1440 -- nor a 4K monitor, but the settings had been tweaked for 1440p. How, why it shows up differently, I can't say.
At this point, I'm clueless why my input is solicited here, but thought I'd contribute to mankind and science. The rig scores very well on 3DMark's Firestrike Extreme, so I had concluded it was "OK."
