ASRock Develops HUDIMM Memory Standard: DDR5 with Just One Sub-channel

You know we’ve hit rock-bottom with memory affordability when ASRock innovates a new memory standard to lower prices. The new “HUDIMM,” or half unbuffered DIMM, is an ASRock-innovated standard. It calls for UDIMMs with half a rank of memory, populating just one of the two 40-bit sub-channels. Such a DIMM would only offer half its bandwidth even at its rated memory clock, and of course half the density. The HUDIMM standard is targeted at entry-level builds and business desktops that just want a modern platform for everyday tasks, and something to tide over the DDR5 memory crunch. ASRock partnered with Team Group to manufacture the first HUDIMM memory modules, which it tested to work on its Intel 600-series, 700-series, and 800-series chipset motherboards. HUDIMM support probably requires some UEFI firmware-level awareness of the standard, and ASRock is expected to release firmware updates for the same.
