The DDR5-12052 memory overclock speed is achieved by "saltycroissant", an extreme overclocker from Canada, using the Intel Core Ultra 7 265K desktop processor and ASRock Z890 Taichi OCF motherboard. Meanwhile, the DDR5-12054 memory overclock speed is achieved by "speed.fastest", an extreme overclocker from Indonesia, using the Intel Core Ultra 9 285K desktop processor and ASUS ROG Maximus Z890 Apex motherboard.

While earlier records were usually broken with extreme sub-zero LN2 or dry ice cooling, reaching over DDR5-12000, the two latest ones were done on water cooling and air cooling, which is definitely an impressive result. Both overclocking records were achieved by using a single module from the G.Skill's Trident Z5 series DDR5-8000 CL38 2x48GB (F5-8000J3848F24GX2-TZ5K) memory kit.
