DDR3 Overclocking World Record: 2.31 GHz

About a week ago, HWBOT posted a video of a new DDR3 memory clock record which was apparently beaten the very next day after the movie was published. Tom's Hardware reported on the first of the two, allegedly performed by Gigabyte on their Z97X-SOC Force LN2 Motherboard. The Tom's Hardware article also, erroneously, lists the 2nd place overclock (then 1st place) at 4.56 GHz when it was really half that, because DDR is duplex (2.28 GHz). This team posted their video with a recording of the overclock being measured by an oscilloscope. This asserts that they did not mess with HWBOT.
The now first place team, which managed 2.31 GHz on the same motherboard, did not go to the same level of proof, as far as I can tell.
This is the 2nd fastest overclock...
... but the fastest to be recorded with an oscilloscope that I can tell
Before the machine crashes to a blue screen, the oscilloscope actually reports 2.29 GHz. I am not sure why they took 10 MHZ off, but I expect it is because the system crashed before HWBOT was able to record that higher frequency. Either way, 2.28 GHz was a new world record, and verified by a video, whether or not it was immediately beat.
Tom's Hardware also claims that liquid nitrogen was used to cool the system, which brings sense to why they would use an LN2 board. It could have been chosen just for its overclocking features, but that would have been a weird tradeoff. The LN2 board doesn't have mounting points for a CPU air or water cooler. The extra features would have been offset by the need to build a custom CPU cooler, to not use liquid nitrogen with. It is also unclear how the memory was cooled, whether it was, somehow, liquid nitrogen-cooled too, or if it was exposed to the air.
