HP Dl380 G7 HP NC382i DP Multifunction Gigabit Server speed problem

Hi,

I have installed windows 2012 on a DL380 G7 and I have a problem with nic ( NC382i DP Multifunction Gigabit Server) the max speed is 100mb and not 1gb as should be.

I have also installed the last firmware and driver from hp website. The switch is ok.

Any advice ?

Thanks
