MSI adds HUDIMM DDR5 memory support to its Intel 600-800 series motherboards
MSI is fully supporting HUDIMM technology on its Intel DDR5 motherboards
MSI has confirmed that it has completed a “comprehensive rollout” of BIOS updates to enable DDR5 HUDIMM module support across its Intel 600, 700, and 800 series motherboards. This has enabled HUDIMM support with Alder Lake, Raptor Lake, and Arrow Lake series CPUs.
DDR5 HUDIMM memory modules aim to make DDR5 memory more affordable by using only one of each module’s 32-bit memory sub-channels, giving PC builders a more affordable entry-level DRAM option. This allows module makers to reduce the number of DRAM chips required to build a DRAM module, thereby lowering costs.
While HUDIMM modules are more affordable, these modules come with trade-offs. Using only one of DDR5’s two memory channels effectively halves available bandwidth. If your workload is bandwidth-constrained, it will limit your PC’s performance. It also means that two HUDIMM modules will have roughly the same bandwidth as a single standard DDR5 module.
MSI today announced a comprehensive rollout of motherboard BIOS updates for its entire Intel 600, 700, and 800 Series lineups, introducing full compatibility with the newly launched HUDIMM (Single Sub-Channel DDR5, 1 x 32-bit) memory modules. This rapid deployment reflects MSI’s commitment to providing flexible hardware solutions for all users, particularly as global DDR5 memory prices remain elevated due to ongoing supply constraints.
HUDIMM is an emerging DDR5 specification designed to lower the barrier to entry for modern PC platforms. Unlike standard DDR5 UDIMMs, which use dual 32-bit sub-channels, HUDIMM architectures use a single 32-bit sub-channel. By optimizing the DRAM chip count per module, HUDIMM enables memory manufacturers to reduce production costs significantly. This makes the DDR5 ecosystem far more accessible to mainstream users, system integrators, and entry-level builders who were previously constrained by high component pricing.
MSI’s latest BIOS firmware ensures seamless detection, optimal initialization, and rock-solid stability for HUDIMM modules right out of the box, requiring zero manual configuration from end-users.
To take advantage of this new memory standard, MSI encourages users to download the latest BIOS firmware for their respective motherboards. Please visit the official MSI website to download the update and view the full motherboard support list here.

To enable HUDIMM support, MSI motherboard users need to upgrade their motherboards to the newest available BIOS version. This will enable seamless detection and “rock-solid stability” for DDR5 HUDIMM memory modules.
Currently, MSI and no other motherboard manufacturer has discussed DDR5 HUDIMM support for AMD platforms. At present, no AMD AM5 motherboard supports HUDIMM memory modules. This makes HUDIMM support Intel-exclusive, at least for now.
You can join the discussion on MSI adding HUDIMM support to its Intel 600-800 series motherboards on the OC3D Forums.
