ASRock, Intel, and Teamgroup are teaming up to tackle one of the biggest headaches for budget PC builders right now: rising DDR5 memory prices. Their answer is a new approach to DDR5 module design called “One Sub-Channel” DRAM, arriving under two new standards, HUDIMM and HSODIMM, aimed at making DDR5 more cost-effective without breaking everyday performance.
So what’s changing? Traditional DDR5 UDIMM memory sticks use two 32-bit sub-channels (2 x 32-bit). The new HUDIMM design cuts that in half, using a single 32-bit sub-channel (1 x 32-bit). The idea is simple: many mainstream and budget builds don’t need the kind of high-capacity, fully populated modules that make dual sub-channel designs more expensive. By reducing what’s required on the module, manufacturers can potentially lower production costs—and, ideally, final pricing for buyers.
Intel’s Robert Hallock, Vice President and General Manager for Intel’s Enthusiast Channel Segment, highlighted that innovations like ASRock’s One sub-channel DDR5 technology matter because they help keep desktop computing accessible as DDR5 demand and costs climb. Intel is also backing support for this new memory direction across its 600-, 700-, and 800-series chipsets, expanding the potential user base right away.
One of the biggest takeaways is that this isn’t being positioned as “cheap DDR5 that feels slow.” ASRock has already enabled HUDIMM DDR5 support on its Intel 600/700/800 series motherboards and has shared early performance figures suggesting the experience remains strong. The tradeoff isn’t primarily raw speed—it’s capacity and module population. With HUDIMM, fewer DRAM banks are occupied because the module uses fewer DRAM ICs, which can limit how large a single stick can be compared to fully populated UDIMM modules.
Interestingly, ASRock’s testing indicates HUDIMM can also play nicely with standard DDR5 UDIMM in mixed configurations. In one example, an 8 GB HUDIMM (1 x 32-bit) paired with a 16 GB UDIMM (2 x 32-bit) delivered higher bandwidth than a single 24 GB UDIMM (2 x 32-bit). The practical message here is that budget buyers might be able to reach useful memory capacities at a lower cost by combining a less expensive HUDIMM with a traditional stick, instead of having to buy a larger single module.
Beyond desktops, the same concept is also coming to smaller form factors through HSODIMM. It’s being framed as a budget-friendly alternative to current SODIMM-style memory, with the promise of strong performance, lower pricing, and compact sizing—an appealing combination for cost-conscious laptops and small PCs if it reaches broad adoption.
For budget gamers and practical PC builders, this collaboration is an encouraging sign that the industry is looking for real structural fixes rather than minor discounts. The remaining question is the one that matters most: whether HUDIMM and HSODIMM will translate into noticeably lower DDR5 prices on store shelves. If memory makers roll out a variety of kits quickly and motherboard support continues to expand, these new DDR5 standards could become a meaningful path to more affordable upgrades and new builds in the DDR5 era.
