Hallo all,
Unfortunately, AMD does not provide all the information about the PCIE Lanes of the Ryzen 5 PRO 4650G on their site.
I use this CPU in combination with an ASROCK X570M PRO.
If I understand correctly, pcie slot_1 and slot_3 run on X16 when used alone.
if both slots are in use, slot_3 will still have x4 available and slot_1 will continue to run at x16.
These PCIE x16 slots are directly connected to the CPU.
My mobo has 2 m.2 connections. 1 of these is also directly connected to the CPU via 4 lanes.
Maybe a stupid question but I can't find anywhere in the documentation which of the 2?
In addition, the CPU communicates with the chipset through 4 lanes.
The 2nd m.2 slot is connected via this chipset and also the 8 sata ports and the last PCIEx1 port.
If I have also understood this correctly, not all 8 sata connections are available anymore when I use the 2nd m.2 slot.
Again I can't find anywhere which ports are blocked.
As indicated, not all information about the number of PCIE lanes is listed on AMD's site, but I read somewhere that 20 lanes are available.
In my current setup:
* Silverstone CS381 case.
* All 8 drives connected to the backplane via LSI HABA card.
* m.2 120 gbit as boot drive.
Since I only use this setup as a nas, this works fine.
What I would like:
* adding a 2 port 10gbe network card in the 2nd X16 slot.
So it runs at 3.0x4 which is sufficient as far as I've read
* Add 2nd nvme for temporary files (e.g. the
extracting downloaded files via NZBGet).
* Add 2 internal SSD through the sata ports for using
Docker.
My simple mind then tells me that this won't work because I don't have enough lanes available from my CPU.
PCIE slot_1 = 16 lanes
PCIE slot_2 = 4 lanes
NVME_1 = 4 lanes
Motherboard connection to the chipset = 4 lanes
This is a total of 28 lanes which I do not have available.
Am I completely missing the point and are you laughing at me? Or is it correct as I think?
I hope there is someone who can give me a clear explanation.
Thank you very much!
