Corsair Memory, a leading supplier of high-end memory modules, has managed to set a new DDR3 memory clock-speed world record. The company used its Dominator GTX6 memory modules as well as AMD FX-8150 "Zambezi" microprocessor. Unfortunately, Corsair managed to set the record in single-channel mode, which makes it rather useless for the real world.
In a bid to reach 3467.8MHz (1733.8MHz), Corsair utilized Asus Crosshair V Formula mainboard as well as AMD FX-8150 microprocessor and Dominator GTX6 1GB DDR3 memory module cooled by liquid nitrogen. The chip operated at 4045.6MHz in single-module/dual-core mode and after numerous attempts its integrated memory controller managed to run Corsair's DDR3 memory in single-channel mode at 3.468GHz clock-speed, which is less than 10MHz higher than the previous record of 3.460GHz.
While it is remarkable that some of AMD FX-8150 "Zambezi" microprocessors may not only set records in internal clock-speeds, but also renew world's DDR3 frequency records with Corsair Dominator GTX 1GB modules, it should be kept in mind that the effect of such overclocking has little or no practical value.
"Breaking overclocking world records requires skill, ingenuity, and the right equipment. I have broken several records using Dominator GT memory. It is reliable, it has amazing headroom, and it's never let me down," said Jake Crimmins, a champion overclocker and an employee of Corsair.
AMD's FX microprocessors have dual-channel memory controller and therefore enthusiasts are trying to overclock memory in dual-channel mode. Memory bandwidth provided by single-channel memory at 3.468GHz is 27.74GB/s, whereas in dual-channel mode even 2.4GHz modules can achieve 38.4GB/s even without liquid nitrogen. In addition, 1GB of memory is not enough to run modern benchmarks, so the actual advantage of extreme memory speed cannot be measured.
Despite of little practical effect of extreme memory overclocking in single-channel mode, Corsair Memory regains DDR3 memory clock-speed crown from G.Skill.
