The soaring price of memory has affected all aspects of the technology industry. For PC users with limited budgets, high memory prices are now indispensable for assembling devices. Over time, the prices of other components, including solid-state drives, are also rising. However, ASRock has now joined forces with Intel and TeamGroup to launch single-channel DRAM. This technology is named HUDIMM and HSODIMM. Its main feature is that HUDIMM memory modules only use 1x32-bit channels.

Standard UDIMM memory modules use dual channels, that is, 2x32 bits. Compared with standard memory modules, this single-channel memory is produced at a lower price, so in theory it can be used to deal with the current problem of high prices for traditional standard memory modules.

ASRock 600/700/800 series motherboards support this technology:

Intel said that ASRock's single-channel DRAM technology is critical to the continued popularization of DDR5 memory as the demand and cost of DDR5 memory continue to rise. Intel is very grateful to ASRock for its support in using this technology for Intel 600/700/800 series chipsets, which will allow Intel users to better enjoy the advantages of DDR5 memory in the next few years.

ASRock has enabled support for HUDIMM DDR5 memory on its own Intel 600/700/800 series motherboards. Although the number of sub-channels has been halved, judging from the data released by ASRock, this memory module can still provide good performance.

There is basically no impact on performance:

Pictures posted by ASRock on social media show that using an 8+16GB memory combination in a DDR5 configuration can achieve higher bandwidth and lower latency. The reduction in the number of channels will only reduce the memory capacity, so there will be basically no impact on performance.

The performance data shared by ASRock shows that the overall bandwidth of a single-channel 8GB memory module + a 16GB dual-channel memory module is higher than that of a single dual-channel 24GB memory module, so it is no problem to mix and match single-channel and dual-channel memory modules.

Of course, the key significance is that the production price of single-channel memory modules will be cheaper, so the actual selling price will also be cheaper. Taking a single-channel 8GB memory module + 16GB dual-channel memory module as an example, its price is lower than a single dual-channel 24GB memory module.

However, it is still unknown whether single-channel memory modules can really reduce prices. After all, the biggest problem currently is production capacity. Flash memory manufacturers have moved more production capacity to the more profitable HBM series of memories, so even if single-channel memory production costs are low, they may not be able to obtain sufficient production capacity.
