A new record has been set for DDR5. Obviously we’re talking about overclocking, and the ceiling exceeded by German overclocker sergmann was achieved on a GIGABYTE Z890 Aorus TACHYON with Corsair Vengeance chips, which he was able to push to a frequency of 6504.0 MHz. This performance was made official on Hwbot, while Saltycroissant also exceeded 13,000 MT/s on the same GIGABYTE Z890 Aorus TACHYON motherboard…but unofficially.
This speed of 13,010 MT/s was achieved with CL68-127-127-127-2 timings. The ratio between the Integrated Memory Controller (IMC) and the memory clock was 3:190, a high ratio crucial for these high frequencies. In detail, the magic recipe for this record is a 24 GB Corsair Vengeance memory module, combined with a GIGABYTE Z890 Aorus Tachyon ICE motherboard and an Intel Core Ultra 9 285K processor. Of course, record-breaking overclocking requires the use of liquid nitrogen cooling. Liquid nitrogen cooling was used for both CPU and memory to support these extreme speeds.
13,000 MT/s: a ceiling for DDR5?
The year 2025 has seen a proliferation of DDR5 records. Many overclockers easily broke the 10,000 MT/s barrier, and several have exceeded 12,000 MT/s in recent months. Progress in frequency, however, had been stagnant for several months, confirming a kind of ceiling that seemed to freeze below 13,000 MT/s. This record is therefore something of a small event in the OC community.
But the performance also raises the question of whether moving from 13,000 MT/s to 14,000 MT/s is not a much more arduous mission than moving from 12,000 MT/s to 13,000 MT/s, due to the increasing complexity of these extreme overclocks. Resistance to the 13,000 MT/s ceiling could mean that we’ve reached the limits of DDR5.
