Asus has released new UEFI BIOS versions for its Intel 600 and 700-series motherboards that add support for 64GB DDR5 unbuffered memory modules. The new UEFI BIOS also enables systems with 256 GB of memory to be built using Intel's Alder Lake and Raptor Lake processors.
To build an Intel 600/700-powered system with 256 GB of DDR5 memory using four unbuffered DIMMs, one will need to download and install the latest UEFI BIOS version for their specific Intel 600/700-series motherboard from the Asus website.
