PCI lane limitation?

[CheesyPete]

Hello, I don't quite know what I'm doing so if someone could help me that would be much appreciated.

 

My PC:

• CPU - AMD Ryzen 5 2600X
• Mobo - MSI B450 GAMING PRO CARBON MAX WIFI
• Storage - 2x Sabrent PCIe SSD 500GB (and a couple SATA HDDs/SSDs)
• GPU - Zotac Nvidia GTX 1070

 

I have recently purchased a PCIe USB 3.0 expansion card (here). Now I when I put this card in my PC it is all fine but it only detects one of the 2 PCIe SSDs. Both in the BIOS and on the OS. Now I presume this is possibly a PCI lane problem, I did not assume this would be problematic and I assume it is on the CPU level? I am nowhere near saturating the amount of PCIe slots on the mobo. But is there a solution to this, buying a new CPU is not an option here, I really don't need an upgrade but I would quite like some more USB ports.

 

Thanks for your help :)

Just some extra info, dual boot one of the SSDs is for Windows, the other Linux and I don't actually access one from the other, so I would be satisfied if I could enable one of them in the BIOS before I switch between them, I don't know if that would be possible?

Ah, thanks, is there any reasonable way to get this same kind of functionality?

Would something like this be a good solution, and do you know if I could boot from it?

well that won't really help you here, as the m.2 slot disables those pcie slots.

 

Your board has 2 m.2 slots. You want to use 2 m.2 drives. It will work fine. You won't need any adapters.

The USB expansion card disables the m.2 slot, I am thinking if I have this I would be able to have the best of both worlds, i.e using 2 of PCIe SSDs as well as using the USB expansion card?

If you just need more usb ports, why not get a usb hub instead?

Yes I suppose, just like the clean setup of it all being integrated, I will look into it.

 

Thanks for the help though!

that is a hilareously terrible pcie layout...

 

your best bet here is an external usb hub, or before mentioned M.2 adapter thingy, that does mean that both the usb card and the SSD will be running at pcie 2.0 1x speeds (500MB/s, essentially the same as one usb 3.0 port)
