Thank you for posting at Wired Communities. Version Driver 188.8.131.52 refers to the software package version while version 184.108.40.20602 is the actual driver version. You mentioned the NIC does not seem to work well, can you
provide more information what is the issue?
I've tried to copy from different machines and the speed not goes over 512Mbits and the progress of data while transferring is discontinuous between 50/60 MB/sec to 0.
After some seconds, resume, then again.
Resumes but with this swing always.
I think that this is a strange behavior.
The same behavior is between 10G to 10GB and 1G to 10G nics, between 1G to 1G nics is OK and the speed is stable between 700/900Mbits.
It could be a problem with DELL R610?
For additional information, one machine is Windows 2012 R2 GUI (overheating problem on X540-T2) and other is an Hyper-V core 2012 R2 with X540-T2 always.
All two machines are updated by last Microsoft Updates.
Thank you for the additional information. If the NIC is overheat then this will affect the performance, please ensure the NIC is installed and run in the supported operating temperature range between 0-55 degree celsius.
Have you also checked with Dell* support if this NIC has had any compatibility issue with their system? Normally the system vendor validate which components can be supported on their system.
