How to Clear the RAM of Your TI 83/84

Steps

1. Go to the memory screen. You can get to this menu by pressing the 2nd button and then MEM button or the(+).
2. Select the MEM Mgmt/Del. This is should be the second selection from the top.
3. Select "All...". This is the first one from the top. This will show you all your programs and applications.

5. Try to archive all of your programs. To archive put your arrow on the program and press enter. This should archive the program, store it safely, if you have enough ARC. If you can archive all the programs skip the next step.
6. Clear the RAM. To do this go to the MEM menu. Then scroll down to "Reset..." and press enter. Then select "ALL RAM...". This will delete anything not archived and reset the whole calculator to default settings. This should clear up the system and increase RAM and ARC to you maximum amount.

Tips

• If you can not archive all of your programs, you will need to garbage collect some of you programs. To do this press 2nd CATALOG or 0. Then press TAN button. That should bring you to the command GarbageCollect. Garbage collecting gets rid of the "garbage" created by archiving and unarchiving programs. Press enter and then press it again and select yes. Then go and archive all the rest of your programs.
• If you can not archive all the programs after garbage collecting, then you may have to consider deleting unnecessary programs like the languages.
• It is also recommended that you store all your programs in your computer so that you can delete them in your calculator or just in case you accidentally delete a program.
• If a file is archived it will not be deleted by clearing the RAM and with the use of applications such as Mirage OS you can use activate your programs even if they are archived.
• To get out of the MEM menu press clear.

Warnings

• If you do not archive all your programs the unarchived ones will be deleted when you clear the RAM.
