Nvidia Control Panel takes 5 mins to initialize


We have a Supermicro SYS-4028GR-TRT with 4x NVIDIA Tesla K80 24GB installed. Running on Windows Server 2012 R2 Standard 64 Bit and our driver version is 377.35. We do not attache a display to this system.

When we try to run Nvidia Control Panel, it takes 5 minutes for it to initialized and ready to be used.

Please advise.
