I think that I understand a concept, but i'd like to get some validation from you smart people.

 

Here is my hypothetical system:

ASrock X570m Pro4

Ryzen 5 3600

ASUS Hyper M.2 X16 PCIe 4.0 X4 (4x 250gb Samsung 980 pro)(speedy boi data)

ASUS GT 710 X1

1x 250gb Samsung 980 pro(OS)

USB C 10gbps NIC

 

 

According to their respective spec sheets, the X570 motherboard should have "up to 36 PCIe lanes", and the 3600 has 16 PCIe lanes. 

 

I'd like the M.2 card to use the 16 from the CPU, and the video card and the onboard M.2 to come off the chipset. Assuming I put the M.2 card in the top slot, it should run correctly, right? 

 

So with drives/video card/ and M.2 card, i've got 21 lanes used.

 

I'm trying to make sure that the advertised number of lanes isn't a "whichever comes first" sort of situation.

Total number or lanes doesn't mean much, what does is what features/slots are on the board and any notice in the mobo manual about some things being disabled when others are used if any.

For full x16 speed, connect it to the top x16 slot, that's usually connected to the CPU directly

 

The second x16 slot is usually x4 electrically only, so you can connect your gpu there as it's only functioning as display out I assume and doesn't need lots of bandwidth

 

As for m.2 slot, you can connect it to any slots, if you go through the chipset then that's fine, but AMD CPU have dedicated lanes to m.2 from the CPU too, which is usually the top slot and it won't affect the x16 card

Things I need help with: (nothing at the moment)

Spoiler

none atm

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

Spoiler

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

Personal Blacklisted Companies:

Spoiler

Acer: shit tier quality products, shit tier customer service thus far, they "tried" to solve my issue but they arent really doing anything but delaying and delaying. (on-going case since July)

Gigabyte: horrible customer service (gigabyte had literally 0 customer service, asked me to go to retailer with NO WAY to email them about a question) but at least they fixed my shit in ONE MONTH (would probably take me 1 hour to fix if they let me email them)

XiaoMi Phones: built like a tank but the software is buggy as all hell

Seagate HDD: had too many dead seagate drives

Kingston SSD: 300V controller swap thingy

Razer (except their mouse)

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

Also note that this hyper m.2 card requires the motherboard to support PCIe bifurcation, which is supported by ASUS boards marked as compatible but not every manufactuer enables that on ATX boards.

 

That board seems to support it.
