Intel X520-DA2 cards not getting 10gb in Windows

[JesterJeff69]

I just purchased an Intel x520-da2 and 4x lenovo x520-da2 cards.

All are working to a brocade 7250 but for windows I am only getting 2.5gb speeds. Windows states cards are connected at 10gb but iperf3 shows 2.5gb, file copies show 400-500mb transfer.

When I had Mellaxon Connectx-1 and 2 cards, in the same machines, i did get 10gb. 

I am switching from mellanox because they are the old cx4 plug style and obsolete where esxi, truenas and proxmox do not see them.

I even had issues trying to get drivers installed for both the true Intel and the Lenovo ones. Tons of googling, lead to prowinx64.exe that at least got me started then i found drivers to run.

I am running Driver version 4.1.251.0 (Driver Date:"06/27/2023 12:00 AM")
from Intel on all of the cards.

1x Manufacturer:"Intel" Part Number:"E68793-000"

4x Lenovo Part Number:"G63082-006" (FRU 49Y7962)

Now, if I run Linux on two machines, I get 9.4gb speeds thus I am dealing with a firmware issue or driver issue and trying to get this going.

Windows 11 iperf3 back to Parted Magic - 949Mbits/sec

Parted Magic on two machines - 9.41Gbits/sec

There are 4 full systems here... all doing the same thing.

The issue is not the systems as I can boot off of a linux distro and get full speeds. it has to do with Windows and drivers for this card.
