Nowadays, the clock-rate of dynamic random access memory no longer plays a crucial role in PC performance. Nonetheless, enthusiasts are still trying to set DDR3 DRAM clock-rate records and find the best memory modules available. This week G.Skill, a leading supplier of enthusiast-class DIMMs, announced that enthusiasts had managed to boost clock-speed of its TridentX 3.0GHz modules to whopping 4.40GHz.
Using the new-generation Intel Core i7-4770K “Haswell” microprocessor (en engineering sample), Asus Maximus VI Impact mainboard and a custom LN2-based cooling system for both central processing unit and memory module, professional overclocker James “YoungPro” Trevaskis from TeamAU was able to push the G.Skill TridentX DDR3 3000MHz C12 4GB stick to unprecedented 4404MHz with CL13 31-31-45 latency-settings.
Just like in previous cases, the world’s memory frequency record was set in single-channel mode. While modern microprocessors with integrated memory controllers can handle rather extreme memory clock-rates in dual channel mode (e.g. 3.0GHz and upwards) or even quad-channel modes, to reach the unparalleled frequency one must use only one memory module. As a consequence, there is no practical meaning in using 4.404GHz single-channel memory sub-system (with 35.232GB/s peak bandwidth) since it will be outperformed by dual-channel memory sub-system running at 2333MHz (with 37.3GB/s) and simply smashed by quad-channel memory sub-system operating at 1866MHz (59.712GB/s).
Despite of lack of practical meaning, G.Skill’s TridentX DDR3 3.0GHz has reclaimed world’s fastest DDR3 module title for the manufacturer.
