Dell YT583 manual Removing Memory With Optional Memory Riser Cards, 187

19Connect your computer and devices to electrical outlets, and turn them on.

20Press <F2> to enter system setup and check the values listed under Memory Info.

The computer should have changed the value of Installed Memory to reflect the newly installed memory. Verify the new total. If it is correct, skip to step 22.

21If the memory total is incorrect, turn off and disconnect your computer and devices from their electrical outlets.

Return to step 1 of this procedure, but instead of installing new memory, check the installed memory modules to ensure that they are seated properly in their sockets.

22When the Installed Memory total is correct, press <Esc> to exit system setup.

23Run the Dell Diagnostics to verify that the memory modules are operating properly. See "Dell Diagnostics" on page 123.
