ASUS has also demonstrated its support for upcoming HUDIMM DDR5 memory on ROG motherboards, leading to cost-effective PC builds.
ASUS Demos Initial Support For Budget-Aimed HUDIMM DDR5 Memory Sticks On Its Intel Motherboards
Yesterday, ASRock, along with Intel & Teamgroup, announced a new cost-effective memory standard called HUDIMM. This new memory standard enables PC builders to make cost-effective PCs by using "One Sub-Channel" memory designs instead of "Two Sub-Channels". This essentially slashes the DRAM capacity in half of what the modules are actually capable of.
The reasoning behind this technology is simple. 16 GB, 24 GB, and higher capacity memory modules are out of reach for budget PC builders. Hence, rather than using the full "Two Sub-Channel" or 2 x 32-bit layout, why not go for just one sub-channel or 1 x 32-bit layout? This cuts the memory to half, but also offers lower prices.
You can also mix and match HUDIMM with standard UDIMM modules. In one example, an 8 GB HUDIMM module was paired with a 16 GB UDIMM module, and the performance aspect was just as good as a single UDIMM kit.
Now, ASUS's ROG motherboard R&D engineer has demoed HUDIMM modules on the ROG Z890 APEX motherboard. The motherboard was just used for demonstration, and shows that putting tape over the gold fingers can essentially limit a UDIMM to one sub-channel.
Bing used two 24 GB modules, taped them, and you can see how the total capacity of the DRAM shows up as 24 GB (12 GB x 2) instead of 48 GB (24 GB x 2). This is because both DIMMs are running at one sub-channel mode.
Bing also got access to a Teamgroup HUDIMM module featuring 8 GB capacity, one sub-channel, and half of the DRAM banks populated (4 ICs vs 8 ICs). The module booted up in the BIOS without any issues, and are rated at 4800 MT/s which is the baseline speed for DDR5 memory.
For Entry-level PC builders, 16-24 GB DDR5 memory will be more than enough for their needs. Now the HUDIMM standard isn't a permanent solution to the budget PC dilemma. It is just a means to allow entry-level builders with something that makes more sense from a cost point of view until the actual memory prices drop. The memory situation isn't going to get better anytime soon, so in the meantime, HUDIMM might be a decent solution for budget and low-end PC builders.
