W680 boards will work with both DDR5 (up to 4800 MT/s) and DDR4 (up to 3,200 MT/s) ECC memoryW680 looks good, but DDR5 32 GB UDIMM true ECC nowhere to be found, or am I blind?
there is a mainboard that supports both DDR4 & DDR5 but not at same time. separate Slots for each DDR4 & DDR5.EDIT for my bad info
W680 chipset supports both memory standards but they are physically different. Intel is so dumb!
