Asus ROG Crosshair X870E Hero - is it possible to have 2 x PCie5.0 SSD's, without taking lanes from the GPU?

If so, what should the configuration be? The manual seems a bit confusing to me.


*I asked this question on Tom's Hardware Forum, and got the usual nonsense from the moderators wanting to be King-Of-The-World, all while without answering the question and asking for Links/Additional info. I think the question speaks for itself.
 
Ouch! Indeed.
Theoretically, the number of PCIe5.0 lanes of the architecture support x16 for the GPU, and 2 x4 for SSD's?
M.2_1 and M.2_3 might work?
My head hurts. Probably blinded by it all, might be an idea to step back from it for a few days.
Appreciate your input.
 
I think you are correct.

This is why I asked the question, as I'm not sure it's possible. Same for Intel on their newer platform too.

I ask, as in February next year I'm going to be building a new rig, primarily for Gaming, but other production work too. If I could get a motherboard that fully supported 2 x M.2 SSD's at PCIe5.0, then I could have one for OS / Gaming, and one for Production Apps.

However, it does look like both platforms (AMD and newer-Intel) only allow for one PCIe5.0 SSD.

This is fine - it's just something I'd like to be clear on, before I invest in one platform or the other.

I'd really like Motherboard manufacturers to be much clearer on their specifications, explicitly saying what can be supported, as an optimal maximum.

For example: 'This SuperDuper Motherboard supports 1 x PCIe5.0 M.2 SSD and 4 x PCIe4.0 SSD's without sharing bandwidth with other components.', in order to save us all confusion and guess-work.

Certainly, if I was a marketing director, I'd be insisting upon it.
 
I'm happy to run the OS and Gaming drive on the single Gen5 SSD, and use a couple more Gen4 for other drives I will need (Apps, slower-games, mass-storage).

My intention was to see if this motherboard, or the architecture in general, supported 2 x Gen5 SSD slots. As then I could have had my OS/Games and Apps on separate, but fastest slots.

Seems not. No issue with Gen5/Gen4 combination, but had to check if 2 x Gen5 was possible (without taking).
 
Yes, I specced-up 11 motherboards in total of X870E, and made an Excel spreadsheet of what they 'contain'. In general, they contain less M.2 slots than their LGA1851 Intel counterparts - which also only offer 1 x Gen5 SSD; but multiple Gen4.

I will need a motherboard, of whichever manufacturer, to contain (at least) 1 x Gen5 and 2 x Gen4. Without sharing.
 
For Intel it is all very possible.

If I choose Intel for an LGA1851 build, it seems the MSI MEG Z890 Ace would be the one I would pick, after checking some 20+ boards, and seeing a half-dozen that would 'do the job'.

Fast CUDIMM memory, plenty of M.2 (only 1 Gen5 of course), lots of higher-end USB connectivity, with 10GB LAN too.

I looked into AMD as it's CPU's rout Intel for gaming performance; and the 9950X3D due out early next year will probably fly even faster. But gaming isn't everything I need.
 
I agree - as I understand it, while each iteration of PCIe is double the rate of before, to the human eye, it's pretty much the same.

I'll be running MSFS2020, and eventually MSFS2024, so will be putting this on the Gen5 SSD, to stop any potential for stuttering while flying.

Gen4 is fine for everything else.
