A professional overclocker has set up the world’s highest frequency record of 3900MHz. Using AMD A-series “Llano” microprocessor, G.Skill TridentX memory module and liquid nitrogen, Christian Ney managed to substantially increase the record DDR3 clock-speed from 3600MHz.
In a bid to overclock G.Skill TridentX memory module F3-2666C11-4GTXD (based on Hynix CFR memory chips) to whopping 3.90GHz, the overclocker from Ocaholic.ch used AMD A8-3870 accelerated processing unit that operated at just 2089.57MHz and Gigabyte Technology GA-A75-UD4H mainboard along with special Kingpin Cooling LN2 memory pot.
Using liquid nitrogen, Christian Ney cooled down the APU to -190°C and DDR3 module to -120°C and then managed to register and validate 3900MHz clock-speed with CL14 14-14-36 2T timings.
Unfortunately, the professional overclocker has not succeeded in overclocking the module further and set the new speed milestone of 4GHz. Mr. Ney tried to “push more and tighten the timings, but CPU died after 2x 6 hours benching hard”.
