Overview
- ASRock, Intel and Teamgroup introduced HUDIMM and HSODIMM, which use one 32-bit channel per module instead of the usual two to create cheaper DDR5 sticks.
- An ASUS ROG engineer showed the one-channel mode on a Z890 APEX by taping DIMM contacts, making two 24 GB modules register as 12 GB each.
- Teamgroup built an 8 GB HUDIMM with half the memory chips populated, and it booted at the DDR5 base speed of 4800 MT/s.
- ASRock enabled support on its Intel 600, 700, and 800 series boards and said an 8 GB HUDIMM paired with a 16 GB UDIMM outpaced a single 24 GB UDIMM in bandwidth.
- The approach cuts capacity and bandwidth per stick to lower part count and price, with laptop-size HSODIMMs also planned, but availability, pricing, and full validation are still to come.
