I am getting the same error, even after setting the jumper to 2-3.
I am using a Lenovo System-x 3650 server with Windows 2012 R2. Using Dialogic version 6 Su 271.
The PCIe slot is a 16x, 8x, 4x,1x slot rated at 25w.
This is a brand new server. I am an admin of the machine and there is no anti-virus software on it yet.
I have this same problem on two identical servers. Have tried multiple PCIe slots.
