The world record for highest frequency was set by
overclocker "TOPPC" of MSI using a single HyperX Predator DDR4 8G module on an MPG Z390I GAMING EDGE AC.
The latter is particularly interesting-famed
overclocker Kingpin had previously taken a GeForce GTX 1080 Ti, stripped off the heatsink and bathed the card in liquid nitrogen (LN2), and overclocked it to 2,581MHz, which resulted in a score 8,642 in the 1080p Extreme preset.
The cables have reportedly been developed with inputs from German celebrity
overclocker der8auer.
Cooling is an also an important factor especially for
overclocker. Money is the next important factor.
8 -- Using Corsair's Dominator GT GTX6 ultra-high performance DDR3 RAM, an extreme
overclocker named Matthias 'Mat' Zronek from www.overclockers.alt managed to break record DDR3 speeds, setting frequencies of 3078.2MHz on CL8-11-8-31 (CAS 8), 1T, and 3059.4MHz on CL7-11-8-31 (CAS 7), 1T.
It's loaded with features designed for the PC gaming enthusiast and serious
overclocker without sacrificing one for the other like so many competing products.
