Amidst the flood of new product announcements at Computex, G.Skill was busy hosting an overclocking competition where its memory was used to in a record breaking overclock that saw DDR4 memory clocked at an impressive 5,500 MHz. Professional overclocker Toppc broke his 5,000 MHz record from last year with the new overclock that was accomplished on Intel’s X299 platform.
Toppc used a MSI X299 Gaming Pro Carbon AC motherboard, Intel Core X-series processor, G.Skill DDR4 memory built using Samsung 8Gb ICs, and, of course, copious amounts of liquid nitrogen! Looking at the HWBot page, it appears Toppc specifically used an Intel Core i7-7740K (Kaby Lake X) processor and 8GB G.Skill Trident Z RGB RAM (CL 14-14-14-14 stock). Both the CPU and memory modules were cooled with liquid nitrogen for the overclock. The CPU-Z screenshot shows the processor running 1 cores / 2 threads with a 133.06 bus speed. It also shows an 8x multiplier and core speed of 1064.46 but I am questioning whether or not it is accurately reading the Kaby Lake X part correctly as running at those speeds wouldn’t need such exotic cooling – perhaps it is needed to run at the 133.06 bus speed and to keep the memory controller from overheating (or melting hehe).
G.Skill is currently pushing the envelope on standard air cooled DIMMs with a prototype kit hitting 4,800 MHz. The company's CVP Tequila Huang stated in a press release:
“We are seeing amazing overclocking potential for these newly released hardware and we believe that more overclocking benchmark records will be achieved very soon by professional overclockers worldwide."
I am interested to see if it will have any additional headroom in the memory overclocking department and if so how long the 5.5 GHz world record will stand.
