Gigabyte is introducing what it calls the world’s first CQDIMM, or Clocked Unbuffered Dual In-Line Memory Module, technology at CES 2026, positioning it as a breakthrough for high capacity DDR5 performance on consumer platforms. By combining CQDIMM modules with a CQDIMM-supported motherboard, the Z890 AORUS Tachyon ICE CQDIMM Edition, the company reports that it achieves an industry first record of DDR5-7200 without compromise at full capacity with two 128 GB memory modules.
The announcement targets a long standing limitation in DDR5 scaling, where pushing memory capacity higher has typically caused significant trade offs in frequency and stability. Gigabyte presents CQDIMM as a solution that avoids this compromise, claiming users can run very high frequency memory configurations while still populating large capacity modules, something that has been difficult to accomplish reliably in previous designs.
Gigabyte attributes the result to a combination of hardware design changes and firmware level control. On the hardware side, the company says it has optimized motherboard circuit layouts to significantly reduce memory channel loading, which in turn improves signal integrity and keeps operation stable even under heavy workloads. Complementing those changes is what Gigabyte describes as sophisticated BIOS tuning technology that uses an optimized clock driver architecture so that the BIOS can intelligently manage timing, signal synchronization, and voltage behavior to help unlock this level of extreme performance.
