I am recent owner of this board (the D16 WS model) along with dual Xeon E5-2630V4 cpus. Additionally I have installed an Intel 750 1.2TB SSD and a STRIX GTX1070.
My problem is that I cannot get normal 4K SSD performance.
In the previous motherboard that I had the Intel 750, I had around 33MB/s read and 170MB/s write 4K performance in AS SSD benchmark.
After moving the drive to the new motherboard with the dual Xeons, I only get 29MB/s read and 100MB/s write.
The OS is the same in both configurations (Windows 10 Enterprise) with the same firmware and driver for the Intel 750. I am pretty sure that this is because of a power feature in the BIOS (like C-states) but anything that I have changed didn't make any difference.
Any thoughts on which might be the settings for the CPU's in the BIOS that will boost the 4K performance back to normal?
Thanks in advance for your time.
