Make sure the M.2 socket is M keyed. The Predator M.2 card will not work in a M.2 socket that is B keyed (see figure below). This is because only M keyed M.2 sockets support PCIe x4 capability.

The adapter will fit in PCIe x4, x8 and x16 sockets. It will not work in a PCIe x1 socket or a legacy PCI socket.

Try resetting the BIOS to default settings. Check to see that the M.2 socket is enabled. In some cases, the M.2 socket is shared with a PCIe slot. You will have to choose between one or the other. If none of this works, see if there is a BIOS update. You may need to reset the BIOS to default settings again after the update.

Your M.2 socket must be at least PCIe Gen 2 x4 compatible in order to run this card at the maximum speed. The drive will work in a M.2 PCIe x1 or x2 socket, but at a slower speed. Also, make sure that in the BIOS, the M.2 slot is linked to the PCIe bus as a x4 socket.

Yes you can, but you will not be able to use it as a boot drive.

Some motherboards require "Compatibility Support Module (CSM)" be enabled in the BIOS in order to boot from a PCIe SSD. By default, this should be enabled. If it is disabled, please follow the BIOS instructions to resolve the issue or consult your motherboard manufacturer's documentation.

During the OS installation, go to UTILITIES / TERMINAL　

In terminal type:　

diskutil list　

Then press RETURN. Scroll up to top and verify the Kingston SSD disk (i.e. disk0, disk1, etc).

Then type:　

diskutil mountDISK disk0 (or whichever ddisk is the Kingston SSD).　

Then press RETURN. It should show "mounted successfully".

Then type:　

diskutil eraseDISK apfs YOURDRIVENAME disk0 (or whichever disk is the Kingston SSD)　

Warning – This step (eraseDISK command) will delete all data on the target drive. Confirm that you have selected the drive you wish to delete and then continue.　

Then press RETURN. It should show "successful". Then exit terminal and proceed with the normal installation of the OS.

ElectroStatic Discharge, ESD is simply the discharge of built up static electricity.ESD should not be taken lightly as this is one of the few things an individual can do to damage or destroy their computer or hardware components.It is like when you rub your feet on the carpet and you touch something metal.ESD can occur without the user feeling a shock and will occur when only working on the inside of the computer or handling hardware.

How to help prevent ESD
The best method of preventing ESD is to use an ESD wrist strap or a grounding mat or table.However, because most users do not have access to these items, we have included the below steps to help reduce the chance of ESD as much as possible.

• Standing – We recommend that you are standing at all times when working on the computer. Setting on a chair can generate more electrostatic.
• Cords - Make sure everything is removed from the back of the computer (power cord, mouse, keyboard, etc).
• Clothes - Make sure not to wear any clothing that conducts a lot of Electrical Charge, such as a wool sweater.
• Accessories - To help reduce ESD and help prevent other problem, it is also a good idea to remove all jewelry.
• Weather - Electrical storms can increase the ESD risk; unless absolutely necessary, try not to work on a computer during an electrical storm.In very dry areas, the air itself becomes a part of the electrostatic build-up mechanism every time there is an air flow (wind, air conditioning, blower) passing over an insulated surface.Do not let high humidity levels build a false confidence, and beware of corrosion problems with interconnects and other electrical interfaces.
