A new DDR5 memory overclocking record was set – 12,666 MT/s on a CUDIMM module

Among manufacturers of RAM, motherboards, and overclockers, the race for leadership in overclocking RAM continues. Each team is trying to overclock modules of the new DDR5 CUDIMM format to record speeds. ASRock boasted of recent successes, announcing the overclocking of the 24 GB G.Skill Trident Z5 CK memory stick to a new record speed of 12,666 MT/s (6333 MHz).

ASRock itself does not produce RAM. However, the company produces motherboards. The latest memory overclocking record was set precisely on its Z890 Tachi OCF board, designed specifically for overclocking. Obviously, when operating at such memory speeds, conventional air cooling cannot be used. Therefore, liquid nitrogen was used to set the record.

The overclocking was carried out by overclocker Allen Matthew, better known under the pseudonym Splave. Its result broke the previous record for overclocking RAM to DDR5-12634 or 6317 MHz, which was announced on November 27. The flagship Intel Core Ultra 9 285K processor was also used for the new experiment. The chip’s energy-efficient E-cores were disabled, and the productive P-cores operated at a frequency of 2088.8 MHz.

Let us remind you that DDR5 CUDIMM memory differs from regular DDR5 DIMM by the presence of a built-in clock generator, which ensures more stable operation at high speeds. It is for this reason that in recent weeks various teams have been announcing new memory overclocking records. It is quite possible that in the future we can expect even better results from DDR5 CUDIMM overclocking. Such speeds have no practical benefit for ordinary consumers, but show the safety margin of new RAM modules.
