Intel X520-DA2 playing cards not getting 10gb in Home windows

[ad_1]

I simply bought an Intel x520-da2 and 4x lenovo x520-da2 playing cards.

All are working to a brocade 7250 however for home windows I’m solely getting 2.5gb speeds. Home windows states playing cards are related at 10gb however iperf3 reveals 2.5gb, file copies present 400-500mb switch.

After I had Mellaxon Connectx-1 and a couple of playing cards, in the identical machines, i did get 10gb. 

I’m switching from mellanox as a result of they’re the previous cx4 plug model and out of date the place esxi, truenas and proxmox don’t see them.

 

I even had points making an attempt to get drivers put in for each the true Intel and the Lenovo ones. Tons of googling, result in prowinx64.exe that a minimum of obtained me began then i discovered drivers to run.

 

I’m operating Driver model 4.1.251.0 (Driver Date:”06/27/2023 12:00 AM”)
from Intel on all the playing cards.

1x Producer:”Intel” Half Quantity:”E68793-000″

4x Lenovo Half Quantity:”G63082-006″ (FRU 49Y7962)

 

 

Now, if I run Linux on two machines, I get 9.4gb speeds thus I’m coping with a firmware problem or driver problem and making an attempt to get this going.
