Hello,
I have just done what you said you had done, but I got a nice, correct table of values. You might have discoverd a secret command to clear memory.

Cheers.

This is kinda a weird situation. Because it's usually the other way around. Your ram will clear if your calculator is frozen. So take out all 5 batteries from the back. Even the back up battery. Then reset it again. 2nd then + then 7 then 1 Then 2. Good luck.

These instructions are from education.ti.org, and worked for me.

1) Take out one of the AAA batteries
2) Hold down the CLEAR button
3) Put the AAA battery back in while still holding down the CLEAR button
4) Let go of the CLEAR button and turn the calculator ON
5) Press CLEAR to get rid of the error message.

Then you should be good! All the applications on my calculator were still intact, so despite the error message, the RAM was never actually cleared.
