Installing Intel® RST VMD Controller (9A0B) vs. Intel® RST VMD Managed Controller (09AB)


Acer Nitro 515-57 Intel® Core™ i7-11800H Processor 1024 GB PCIe NVMe SSD Intel® RST driver version

Windows® 10, 64-bit*


What is the difference between these controllers and which is the right one to choose during OS installation


Installing Windows® 10 on a laptop with 11th Gen Tiger Lake Processor and need to know the recommended driver between the two options shown below when trying to load the Intel® RST driver during operating system installation:

  • Intel® Rapid Storage Technology (Intel® RST)  Intel® Volume Management Device (Intel® VMD) Controller (9A0B) OR 
  • Intel® RST VMD Managed Controller (09AB)?

In the latest Intel platforms, Intel® Volume Management Device (Intel® VMD) is used to manage storage devices with the Intel® RST software.

The Intel VMD hardware generates 'dummy' devices for multi-function devices when mapped, these functions may be visible to the Windows® operating system. 

The correct selection would be the 0x09AB as this will cover these devices and make sure there are no Yellow bands in the Device Manager for the dummy values.

Additional information

Intel® VMD is intended for VMD Platforms, which are supported only for Intel® 11th Generation platforms or newer
