That wouldn’t necessarily be because of the chipset.
I thought it was, because it is a limitation of the number of pcie lanes. X670E boards seem to have far fewer issues as they 'double up' g so hopefully we will see some general consumer level boards with the new chips/chipsets that don't force you into difficult compromises
You choose the board that meets your needs it not like you get a board with a random set of features.It’s a case of paying your money and taking your choice, but the chipset is very much secondary. If you’re looking to add a boat load of 4x NVME then a board that supports bifurcation is probably the way to go.
The chipset has a set amount of bandwidth to the CPU. How the motherboard manufacturers use that bandwidth is on them. In theory you can add almost whatever you want to the chipset, the over all bandwidth limit will determine the performance throughputs.
AMD don’t use an IMC. You can populate all slots. I used 4x8gb since Ryzen 1000 and X370

I have used 4x8 and 4x16 DIMM since Ryzen 2000 series just fine lol. They are not at all as bad as you are claiming here.
have you tried 4 x 32gb or 4 x 48gb? what rated speeds and timings? 5200 and loose timings is best I can hope for with 7950x3d i have and above and its unstable for me.

We use 4x32GB at work fine on the AMD systems we have no problem. Run stock speeds and timings there.

What board and DIMMs are you using? Curious to see what the max validated speed and config is for your setup on the QVL.
Looking at the Hero QVL 4x48GB is rated up to 5200, 4x32GB is rated up to 5600. Seems fairly normal for the max speed to be lower at the higher capacities.
That said, I've seen people on overclock.net running 128GB at 6000Mhz, but it required manual tuning of timings, voltages etc.

Some Motherboard's have an A and B channel where the B channel doesn't support above JDEC speeds, especially those early AM4 boards which lets face it were not always of the highest quality, that is a limitation of the Motherboard, not the CPU.

I have never had a problem using all 4 slots, my old AM4 system all 4 slots filled will no problem at all.
My son's AM5 system has all 4 slots filled (4x16GB 6000Mhz CL32) using Expo II settings and is running great, I wasn't even planning to fill all his slots, but I had a spare identical ram kit.

Nothing iffy about that at all. 1DPC, lots of system boards specified like that at the moment.
The current EPYC chips are 12 channels and 96 cores.

And there are parts that are Zen4c that are 6 channels, also they go up to 128 cores on some SKU's.
Caporegime
Zen 5c goes up to 192 cores (12 X 16) that would have 12 channel memory, motherboard dependant, on that....
