Figure 81. Installing a memory module Next steps 1. Install the air shroud. 2. Install the GPU riser 1 or second drive bay assembly. 3. Install the GPU riser 2. 4. Follow the procedure listed in After working inside your system. 5. To verify if the memory module has been installed properly, press F2 and navigate to System Setup Main Menu > System BIOS > Memory Settings. In the Memory Settings screen, the System Memory Size must reflect the updated capacity of the installed memory. 6. If the System Memory Size is incorrect, one or more of the memory modules may not be installed properly. Ensure that the memory modules are firmly seated in their sockets. 7. Run the system memory test in system diagnostics.
