Las Vegas, USA, January 6, 2026 — GIGABYTE, a leading global motherboard manufacturer, announced a major breakthrough in DDR5 memory technology at CES 2026. Building on its track record of breaking multiple DDR5 overclocking world records, GIGABYTE has become the first to achieve DDR5-7200 support for 4-RANK CQDIMM (Clocked Quad rank unbuffered DIMM) technology on a motherboard platform, completely redefining the performance ceiling for high-capacity memory.

Industry First: 256GB at DDR5-7200 Out of the Box

The GIGABYTE Z890 AORUS TACHYON (CQDIMM edition) motherboard has achieved an industry milestone—stable boot and operation at DDR5-7200 with just two 128GB CQDIMM memory modules for a total capacity of 256GB. This breakthrough achievement has been verified through professional software including CPU-Z, demonstrating GIGABYTE's deep technical expertise in motherboard design and BIOS tuning.

CQDIMM vs CUDIMM: A New Era in Memory Performance

Traditional CUDIMM (Clocked Unbuffered Dual In-Line Memory Module) memory architecture requires four 64GB memory modules to achieve 256GB capacity, and due to signal integrity and electrical constraints, memory frequency is forced down to DDR5-4400. GIGABYTE's pioneering CQDIMM technology, through optimized clock driver architecture and motherboard circuit design, delivers: 256GB with Just 2 DIMMs: Achieving full 256GB capacity using only 2 modules (2x 128GB), streamlining system configuration and maximizing motherboard compatibility.

⁠

• DDR5-7200 vs DDR5-4400:
  A breakthrough upgrade from DDR5-4400 to DDR5-7200 delivers exceptional performance.
• Enhanced Stability:
  Reduced memory channel load for improved long-term reliability.
• Deep Industry Collaboration:
  By leveraging GIGABYTE’s industry-first support for CQDIMM hardware and BIOS technology, together with optimizations from major memory manufacturers, bringing a new level of advanced performance.

GIGABYTE has established deep technical partnerships with leading global memory manufacturers including Kingston, ADATA, and TeamGroup to co-develop next-generation CQDIMM memory modules. Through collaborative optimization between motherboard and memory sides, CQDIMM frequencies are expected to reach even higher levels, delivering unprecedented memory performance for professional workstations, content creation, and AI computing applications.
