Intel shared this table with us.
If the motherboard has two memory slots total, then the maximum support is DDR5-4800 in any configuration.
If the motherboard has four memory slots total, then the maximum support is DDR5-4400 when two slots are filled with any memory.
If all four memory slots are filled, single rank memory will support up to DDR5-4000.
If all four memory slots are filled, dual-rank memory will support up to DDR5-3600.
So technically Intel listing memory support on Alder Lake as DDR5-4800 is a bit of a misdirection compared to previous launches. If we were to look at parity, two modules in a four-slot board, then really we’d be quoting DDR5-4400. Funnily enough, all of Intel’s benchmarks presented at this launch were run at DDR5-4400, as per specification. Kudos to the testing team to staying within those guidelines.
