What I've been looking for is a board that will allow for 128GBs RAM running at 6000MT/s+
As it is, almost no one even tests 32GB sticks, let alone 4. This keeps me from jumping onto a DDR5 platform.
from what i've seen it sounds like 2DPC boards will clock mem significantly higher on z790. can't say you'll get that w 32GB dimms but there are 64GB (2x32) a die kits available if you know where to look. a die is what you want.
Do you mind sharing a bit more about higher memory clocks with 2DPC and z790? Do you have any links that elaborate a bit more on this as it's the first I've heard of it? Every article i've seen on z790 only references the slight upgrade in pci-e. I'm debating picking up the z690 kingpin while it is still available at a discount for a new 13th gen build and 64GB of ram is my minimum so this seems pretty important. Not that DDR5 64GB ram kits are clocked very high at the moment anyways so maybe it's a moot point?
DDR5 kits come with different ICs, the most common are from Samsung and SK Hynix. For the first year-ish of DDR5, the preferred ICs have been SK Hynix, specifically M Die as this tends to be the best for overclocking/performance. However, the z690 rollout for 2DPC (2 dimm per channel or 4 slot) motherboards was kind of a mess. BIOS can only go so far, and this is why you see pretty much all the world records for overclocking done on 2 dimm boards. While the memory matters, of course, the board topology / memory traces that are used to send and receive signals seems to have been limited in some way early on.
I don't have any links on z790, but I do know some folks who have ES (engineering samples) for z790 and 13th gen (raptor lake) and that is why I say i've heard they have made improvements on this front. Please do not take my word as gospel and go making memory purchases based on rumors and unreleased hardware. It looks promising, but until I have the hardware myself I won't make any promises.
