I install X520-SR2 card at two dell T5820 workstations whose cpu type is Xeon W-2123. Operation System is WIN7 x64. When I use iperf to test speed with each other, the value is only about 350MB/s.

But when I intall X520-SR2 card at two PC whose cpu type is i5 using WIN7 x64 , the speed can achieve to 800MB/s.

What is the problem? help!
