New HUDIMM memory specification debuts with goal of slashing DDR5 prices during RAM shortages — A new, cheaper memory standard with half the bandwidth and half the capacity

DDR5 RAM usually has 2x 32-bit subchannels (single rank), which requires more ICs to populate a 64-bit wide bus. ASRock's new HUDIMM has just 1x 32-bit channel and can work with standard DDR5 in mix-and-matched configs as well. HUDIMM sticks are being made by TeamGroup and are supported on most LGA 1700 ASRock motherboards.
