Overclocker Hits DDR5 World Record With G.Skill Memory and Intel Inside

Last spring, overclocker Seby took some G.Skill Triedent Z5 memory to new heights using extreme cooling and some skillful overclocking. Now, thanks to French overclocker Bl4ckdot, there’s a new record: DDR5-12872.
“We are proud to see G.Skill Trident Z5 memory once again breaking the boundaries,” said Frank Hung, Marketing Manager of G.Skill, in a statement. “This achievement once again demonstrates G.Skill’s commitment to memory overclocking performance.”
Bl4ckdot pulled off the overclocking feat with a custom liquid nitrogen setup and a single 24GB G.Skill Trident Z5 module. He used an Asus ROG Maximus Z890 Apex motherboard, which is the same model motherboard that Seby used to create a record in the spring. The board is a wallet buster, going for more than $600 on both Amazon and Newegg, but it apparently has the chops to handle more than your usual wear and tear.
The heart of the rig is an Arrow Lake CPU. Bl4ckdot worked his magic on an Intel Core Ultra 9 285K processor and the G.Skill memory, resulting in a 3.6GHz clock speed (versus the stock 3.7GHz) for the processor. Overclockers often use a small number of CPU cores for tests like this, so it’s not surprising that CPU-Z shows two cores running on a processor that would generally have 24 cores in operation.
Most importantly, the system included the record-setting DDR5-12872 for the G.Skill memory. That’s a frequency of 6436.1MHz. The memory’s timings are 68-127-127-127-2 (tCAS-tRCD-tRP-tRAS-tCR), which are higher than you would see in a normal rig. When it comes to overclocks, the target component’s frequency is all that matters.
Bl4ckdot and G.Skill submitted the overclock to CPU-Z and HWBOT, so you can check them out. Frequencies like this aren’t possible in everyday PCs—or even high-end gaming rigs, thanks to the short-lived and inconvenient nature of extreme cooling methods. But overclocking has become something of a sport among tech-savvy hardware enthusiasts, and the best overclockers are even able to land partnerships with major brands.
G.Skill has had a big year (and so has SK Hynix, which makes the memory’s ICs). It put out its lowest-latency memory ever for AMD users, targeting the X870 chipset with Ripjaws M5 Neo RGB memory at CL26-36-36-96 in a 64GB, two-module kit. And the company’s Trident Z5 memory has appeared in multiple overclocking records this year.
