In light of the persistent surge in DDR5 memory prices, ASRock has teamed up with Intel and Team Group to unveil the innovative HUDIMM standard. This new standard embraces a single-channel configuration, streamlining the conventional UDIMM's dual 32-bit sub-channels into a unified 32-bit channel. This change reduces the number of DRAM chips by half and substantially cuts down on production expenses. Actual tests conducted by HKEPC reveal that the single-channel read bandwidth of an 8GB HUDIMM registers at only 32447MB/s, marking a nearly 50% decline from the 58913MB/s achieved by a 16GB standard UDIMM. Nevertheless, the latency remains consistently stable within the 85-87 nanosecond range. ASRock has facilitated HUDIMM support on its 600/700/800 series motherboards through BIOS updates. Furthermore, it has been confirmed that when 8GB HUDIMMs are paired with 16GB UDIMMs, the resulting bandwidth outperforms that of a single 24GB UDIMM. Intel has announced that this technology will be extended to compact devices, such as laptops, providing a cost-effective solution in the form of HSODIMM.
