It is more targeted than a factory wipe: you pick what to delete instead of erasing every app and program. ## When to clear memory vs reset **Memory clear** targets history, lists, or graph data. **Factory reset** removes apps, programs, and archived files, required before some proctored exams. Use our [TI-84 Plus CE reset tutorial](https://shoutingnow.com/blog/ti-84-plus-ce-reset-tutorial/) for All Memory wipes. Goal Use this Avoid this Fix a blank or weird graph Clear Y= / plots / ZOOM All Memory (overkill) Free space for NoteFolio Mem Mgmt + GarbageCollect Deleting the wrong app Exam with “no programs” All Memory reset Partial list clear only ## RAM vs Archive vs Apps Storage What lives here Typical clear action RAM Variables, lists, history, RAM programs ClrAllLists, DelVar, Reset RAM Archive Archived programs and apps Delete from Mem Mgmt Apps NoteFolio, Cabri, etc. Delete app or full reset ## How to clear calculator history TI-84 Plus On the home screen, scroll to an old entry and press **CLEAR** line by line, or clear RAM variables that store previous answers. For a fresh session before graphing, clear **Y=** lines you no longer need, see the [graphing equations guide](https://shoutingnow.com/blog/graphing-equations-on-ti-84-plus-ce/). ## Clear variables and lists 1. STAT → 4:ClrList → choose L1, L2, etc. 2. Catalog (2nd → 0) → ClrAllLists for everything at once. 3. DelVar X style commands remove single variables from the home screen. ## Clear graph database and plots Open **Y=** and press **CLEAR** on each line. Check **2nd** → **STAT PLOT** and turn off unused plots. If the graph still looks wrong, **ZOOM** → **6:ZStandard**. ## Memory clear TI-84 Plus CE from the MEM menu 1. 2nd → + (MEM). 2. 2:Mem Mgmt/Del… to delete specific files. 3. Run GarbageCollect from the catalog if archive space is fragmented. Freeing space also helps before you [transfer notes to TI-84 Plus CE](https://shoutingnow.com/blog/how-to-write-notes-on-ti-84-plus-ce/) with NoteFolio. ## Common problems after a partial clear - ERR:INVALID DIM, list missing; re-enter data or clear the stat plot reference. - Still no graph, confirm plot is enabled and window fits the function. - Old regression still graphs, clear Y1 if RegEq was stored there.

Clearing memory is the targeted option, it wipes lists, history, variables, or graph data. A factory reset (**All Memory**) is the nuclear option that removes apps, programs, and notes too. Reach for a memory clear during normal cleanup and save All Memory for when an exam demands a genuinely empty calculator (our [reset tutorial](https://shoutingnow.com/blog/ti-84-plus-ce-reset-tutorial/) covers the steps). ### Will clearing RAM delete archived programs? It will not. **Reset RAM** only touches variables, lists, and RAM programs, and leaves archived apps and files alone. Archived content only disappears if you run **All Memory** or delete it manually in Mem Mgmt. ### How do I clear calculator history on the TI-84 Plus? Scroll up through the home screen and press **CLEAR** on each old entry, or clear the RAM variables holding your past results. If you would rather start fresh in one shot, go to **MEM** → **Reset** → **All RAM**. ### What is GarbageCollect on the TI-84? Think of it as defragmenting: it consolidates fragmented archive space back into usable memory. Open the catalog with **2nd** → **0**, run GarbageCollect, and give it a moment to finish before you send over any large NoteFolio files. ### How do I free space for NoteFolio? Start by deleting programs you do not use from MEM → Mem Mgmt, archive the large files you want to keep, and run GarbageCollect before transferring anything new. The [notes guide](https://shoutingnow.com/blog/how-to-write-notes-on-ti-84-plus-ce/) covers the full sequence. ### Why do I get ERR:INVALID DIM after clearing lists? Something, usually a stat plot or a leftover calculation, is still pointing at a list you emptied. Turn off any plots you are not using under **2nd** → **STAT PLOT**, or re-enter your data in **STAT** → **Edit** before you run 1-Var Stats again. ### Should I clear memory before graphing homework? It is a good habit. Clearing out unused **Y=** lines and turning off stale plots keeps a new function from getting buried under old data, and that small step usually saves you from needing a full factory reset. ```json [{"@context":"https://schema.org","@type":"Organization","name":"ShoutingNow","url":"https://shoutingnow.com/","logo":{"@type":"ImageObject","url":"https://shoutingnow.com/wp-content/themes/shoutingnow-theme/assets/images/logo.png"},"sameAs":["https://x.com/makani20","https://www.linkedin.com/in/makani20/","https://post-see.com"],"contactPoint":{"@type":"ContactPoint","contactType":"customer support","email":"support@shoutingnow.com","url":"https://shoutingnow.com/contact/"},"slogan":"Learn.
