The overclocker pushed the memory to a whopping 4351MHz in single-channel mode, more than double the 2133MHz stock clock.

TweakTown reports that it is still unclear what sort of cooling was used, but LN2 is a possibility. The rest of the system included an MSI X99S XPOWER board and a Core i7-5960X processor, working at just 1631MHz in single-core mode, sans HT.

The CPU tweaks and the fact that a single memory module were used suggest the insane clock would be impossible to replicate in a real world scenario, but at least the potential is there.
