According to HWBOT, the components were cooled using liquid nitrogen. The memory “started up” with timings CL45-120-120-127-2 in combination with a Core Ultra 7 265KF processor, which had energy-efficient E-cores disabled. On large P-cores, the chip operated at 400 MHz.

The G.Skill company, in turn, reported slightly more modest memory overclocking results – 12,042 and 12,046 and 12,066 MT/s. Overclocking was carried out by overclockers BenchMarc, OGS, Dreadzone and CENS. The experiment was conducted using the Asus ROG Maximus Z890 Apex motherboard and Core Ultra 9 285K processor. Liquid nitrogen was also used for cooling. In DDR5-12066 mode, the memory worked with timings CL52-92-92-127-2.
