ASUS ROG Strix X670E-I Chipset Sits on a M.2 PCB
AMD's high-end X670E motherboard chipset combines two Promontory 21 chips working together to deliver a single solution. With regularly-sized ATX motherboards, having two chips to form a chipset is fine, as there is much room on the PCB. However, with Mini-ITX motherboards, packing two Promontory 21 chips is difficult as the PCB area is limited. To combat this, ASUS introduced an interesting solution to solve the problem and allowed the company to ship the high-end X670E chipset inside a Mini-ITX form factor. Thanks to UNIKO's Hardware's findings, we look at the exciting solution ASUS used to solve this problem.
Instead of two Promontory 21 chips side by side, one is placed on the motherboard directly, while the other stands vertically attached by M.2 PCIe slot. Below, the chipset's pictures and the highlight show how it looks disassembled.

You can compare the bottom end male connector size to the M.2 female connector size at the top. It's the same size. Just differently keyed. Therefore it is M.2 sized, just not M.2 standard.
miniPCIE is abit bigger than M.2. You can easily compare them by looking for M.2 to miniPCIE adapters.
PCIE x4 slot is way too big and takes up too much space for it to be there. You can also just search for M.2 to PCIEx4 addon cards and just see how big the connector is when compared to the M.2 slot next to it.
Of course this is all speculation and Asus might be using something totally custom. Can TPU please get an answer from their PR department? TQ
Southbridge does'nt have that of a special role; other then connecting your avg sata, PCI-E slots, USB ports, audio and what more.
The actual chipset is for years inside the CPU these days.
But if you are stupid enough to do what ASUS has done here, and put a high-end double chipset on the absolutely smallest board that doesn't have enough room to expose the connectivity that is the whole point of the high-end chipset, thus entirely negating the whole point of using that chipset, then you are going to run into space constraints! ASUS have not solved a problem, they've invented one and then come up with a solution to it, to make themselves look smart and their products look good - because they are utterly incapable of innovating usefully, i.e. in a manner that adds value to consumers. Hence my "masturbation" comment.
If ASUS was actually smart, they would place the chipsets on the rear of the board and use a metal backplate covering the entirety of the back side of said board, to dissipate the chipsets' heat. But again, they're intellectually bankrupt, so they'll never do something as simple and effective as this.
You will not be able to change how anything on the board works by changing this.
Anyway, this was left out in the name of profit for the 600 series chipsets. I hope at least in the next 700 series, we have the X770 as some kind of iteration of the X570, but much more modern.
it makes literally zero functional sense to have more than the single chip x670 on an itx board. Edit: brainfart, the single chip one is b650e.
and in this motherboards case, the idiocy is simply super blatantly visible.
It looks like the only thing you gain from the chipset upgrade is a PCI-e x1 slot coming from the riser card. How do you use it, though? :wtf:
Nice effort, but I don't see the point.
