Hi, 

Like the title says. Though rightfully recognized in BIOS 3101 Samsung Magician shows the drive as 2TB in Migration Target. 

As well as Device Manager Windows 10. The drive is not listed in the QVL. Only 990 Pro 2TB.

Is the BIOS version too old? Anyone else with this issue?

Maybe you created an MBR partition on this drive? Or you cloned such a partition from a smaller drive? Such a partition is limited to 2TB.
Drives with larger capacities require a GUID (GPT) partition.
