Overview
- ASRock, working with Intel and TeamGroup, unveiled the HUDIMM one‑sub‑channel DDR5 format on Friday, targeting cheaper RAM for entry‑level PCs.
- HUDIMM uses one 32‑bit channel instead of the usual two, which halves per‑stick capacity and peak bandwidth but cuts the number of DRAM chips needed and lowers manufacturing cost.
- An ASUS ROG engineer demonstrated the concept Saturday by taping DDR5 contacts to force one channel on a Maximus Z890 Apex, and a TeamGroup 8GB HUDIMM sample then booted at the DDR5 baseline 4800 MT/s.
- ASRock says BIOS updates on its Intel 600, 700 and 800 series motherboards already recognize HUDIMM, and TeamGroup is preparing compact HSODIMM versions for small PCs.
- ASRock’s internal example shows an 8GB HUDIMM paired with a 16GB UDIMM delivering more bandwidth than a single 24GB stick, though pricing, release dates and independent testing remain unconfirmed.
