Troubleshooting 
If the computer displays a memory error after you have 
turned it back on, turn the computer off and unplug the 
power cord. Open up the computer and make sure the 
memory module is inserted all the way into the slot, and 
then press down on it to be sure it is firmly seated. 
Memory compatibility 
The computer uses UDIMMs (unbuffered dual in-line 
memory modules) that must meet the following 
requirements: 
● 240-pin 
● DDR4-2133 
● Unbuffered, non-ECC (64-bit) 
● 1.5 V 
● 32 GB maximum installable memory 
Because the memory uses dual channels, you must use the 
same memory module type for both sockets. 
NOTE: The actual memory transfer speed might vary based 
on the processor used in your computer. 
NOTE: Memory performance might vary due to different 
system configurations. 
Removing the memory module 
1.  Press the power button to turn off the computer. 
2.  Disconnect the power cord and all attached cables 
from the back of the computer.
