The administrator has just installed a new memory module into the server. Now, the server is not showing the new memory. Which of the following should the administrator perform FIRST?

A system reboot might be necessary after reseating, but if the memory isn't physically seated correctly, a reboot alone won't resolve the detection issue.

Reseating the memory module ensures it is physically installed correctly and making proper contact with the motherboard slot, which is a common reason for new RAM not being detected. This fundamental physical check is typically the first step before assuming software or configuration issues.

Installing the latest firmware (BIOS/UEFI) is a more advanced troubleshooting step, usually performed after basic physical checks, and is less likely to be the immediate cause of new RAM not being detected unless there are known compatibility issues.

Memory modules do not require specific drivers for detection by the operating system, as basic memory management is handled at the firmware level.
