Drivers for server platforms and operating systems are to be obtained directly by the manufacturer of your server. Please contact them in order to obtain the appropriate driver.
Sorry, but nobody said anything about server systems. The system in question is a workstation, and the E3-1275V3 is a workstation processor with a comparatively high-end INTEL GPU on chip.
If anyone can and should provide a driver for that, it's Intel.
If you are looking for workstation processors, it is still best to get them directly from the manufacturer of your workstation system. However, you have the option of using the Intel® Driver Update Utility to locate your driver as well.
