G.Skill held its annual extreme overclocking competitions (the OC World Cup Competition and OC World Record Stage) at Computex 2018 in Taipei where the overclockers managed to break 13 world records including the two highest DDR4 clockspeeds and the fastest Core i7-8700K clockspeed.

Overclocking teams from around the world using Intel processors, G.Skill DDR4 memory, and motherboards from MSI, EVGA, and ASRock along with extreme cooling methods (de-lidding and loads of LN2) were used to set the world records in 3DMark Fire Strike, SuperPi, Maxxmem, Geekbench 4, GPUPi for CPU, WPrime, and PiFast benchmarks along with hardware records of DDR4 5543 MHz and an Intel Core i7-8700K at 7409.03 MHz.

On the memory front, G.Skill notes that Toppc is now the world record holder with the DDR4-5543 MHz overclock achieved using an Intel i7-8700K, MSI Z370I Gaming Pro Carbon AC, and G.Skill Trident Z RGB memory. Following Toppc’s overclock Kovan Yang managed to achieve the second highest DDR4 clockspeed record at DDR4-5541 MHz on the MSI X299 Gaming Pro Carbon AC motherboard and Intel Core i7-7740X processor which is an interesting feat on the HEDT platform.

Other notable benchmark world records include a 3DMark Fire Strike Extreme Single score of 20,320 (i9-7980XE and EVGA X299 Dark platform), Geekbench4 Single Core score of 9842 points (i7-8700K on an ASRock Z170M OC Formula), WPRIME -32M score of 1.937 seconds, and a SuperPi 32M score of 4 minutes and 8.922 seconds.

Interestingly, G.Skill’s video coverage (embedded below) shows both manual full pot cooling as well as the automated Roboclocker LN2 cooler being used. The video jumps from scene to scene quickly but it does give you some glimpses at the process and the pots/heatsinks used with the RAM and processor to keep things cool even when cranking up the voltage and clocks!

Extreme Overclockers Fill Coffee Lake With Liquid Nitrogen

A new CPU means new overclocking challenges and with it comes a new batch of refreshed Z370 motherboards. At the high end, the current frequency record for the Core i7 8700K is 7,405.1 MHz obtained by Hovan Yang using a MSI Z370 Godlike Gaming motherboard.

He’s not the only one testing the limits of Intel’s new six core processors though. Asus held an overclocking event a few weeks ago where renowned overclockers Alex@ro, elmor, der8auer, Rsannino, and shamino battled it out. Der8auer got a pre-release crack at the i7 8700K at the event and after de-lidding and replacing the TIM with liberal amounts of Kryonaut thermal paste managed to achieve 6.8 GHz using 1.8 volts and a 68x multiplier (and bumping the cache speed up to 6.3 GHz). With these settings on the monster Maximus X Apex motherboard, he scored 299 in single threaded and 2253 in multithreaded in Cinebench R15. Der8auer compared this benchmark result to Skylake X at 5.5 GHz scoring 237 in the single threaded test. Following the benchmark run, he went for the highest CPU-z validated clockspeed he could hit and managed to push the chip to 7300 MHz (100MHzx73). From there overclocker Alex from Romania was able to overclock his i7 8700K to 6844 MHz and scored 2306 in Cinebench R15.

The overclockers broke 10 new records in the six core CPU category and also managed to break a DDR4 clockspeed record by pushing a single 8GB G.Skill DIMM to 5529.2 MHz at 24-31-31-63-3 timings!

Also of note is that Coffee Lake does not depend of FIVR so overclockers are able to use a full pot of liquid nitrogen (or liquid helium) to cool the processor down to much lower temperatures so that they can crank up the voltage and achieve much higher clockspeeds than Skylake-X which cannot boot if temperatures are too low.

While the ASUS team does not hold the clockspeed record anymore (though they might regain it with some Liquid Helium), der8auer has an interesting video and Asus has a blog post with photos talking about the process, setup, and everything that goes into these extreme overclocking sessions including pre-binning the chips, preparing the IHS and motherboard for the super cold (-185°C to -190°C) temperatures, and keeping the processors and motherboards running. For example, and Josh will be interested in this, part of the process of preparing the motherboard involves slathering it in Vaseline!

If you are interested in this extreme overclocking stuff it gives a bit of insight into all the fun to be had!

G.Skill Memory Used In World Record Breaking DDR4 5,500 MHz Overclock

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.
