Downgraded PCIE lane speed/width?

[jeremyy44]

Hi,

So I have been looking at how much lanes each of my pcie cards were using and saw something I am not sure about.
I have 3 cards in my server. 1 Quadro P400 , a LSI 9201-8i and a Realtek 2.5gb/s nic with 2 ports.
My cpu is a Ryzen 5 2600 which has 20 pcie lanes.
My worries is that when looking at the output of lspci -vv for each of my cards I saw this in my quadro and lsi card.

QUADRO P400
            LnkCap: Port #0, Speed 8GT/s, Width x8, ASPM L0s, Exit Latency L0s <64ns
            LnkSta: Speed 5GT/s (downgraded), Width x2 (downgraded)
            LnkCap2: Supported Link Speeds: 2.5-8GT/s, Crosslink- Retimer- 2Retimers- DRS-
            LnkCtl2: Target Link Speed: 8GT/s, EnterCompliance- SpeedDis-
Realtek 2.5 GB/s NIC 2 ports
            LnkCap: Port #0, Speed 5GT/s, Width x1, ASPM L0s L1, Exit Latency L0s unlimited, L1 <64us
            LnkSta: Speed 5GT/s (ok), Width x1 (ok)
            LnkCap2: Supported Link Speeds: 2.5-5GT/s, Crosslink- Retimer- 2Retimers- DRS-
            LnkCtl2: Target Link Speed: 5GT/s, EnterCompliance- SpeedDis-
LSI 9201-8i
            LnkCap: Port #0, Speed 8GT/s, Width x8, ASPM L0s, Exit Latency L0s <64ns
            LnkSta: Speed 5GT/s (downgraded), Width x2 (downgraded)
            LnkCap2: Supported Link Speeds: 2.5-8GT/s, Crosslink- Retimer- 2Retimers- DRS-
            LnkCtl2: Target Link Speed: 8GT/s, EnterCompliance- SpeedDis-

I saw that they were "downgraded".
From what I understand the quadro p400 is working at x8 width even tho it is supose to be at x16. The lsi is a x8 card so idk why it says downgraded.
What am I missing here and should I be worried about wasted performence? Would it be worth upgrading to a plateform that has more pcie lanes?
And from this how can I tell how many pcie lanes are currently in use?

Thanks in advance for any help/

this CAN be a normal behaivior in the case the system just want s to save power. on load the PCIe gen is back to 3 and all 8 lanes will be uses.

This is power saving modes "ASPM"
L0s – A low resume latency, energy saving “standby” state.

You can disable them by changing cpu governor to performance vs OnDemand.
