Does anyone have any suggestions on what kind of memory it is?

There is a table A1:Z4000, when I select this table and replace $L with $U,
the speed of running through the table is very quick from A1 to B3000, but it
runs very slow from B3000 to Z4000, and pop up a window for enough memory.
Does anyone have any suggestions on what kind of memory it is?
I get 2GB RAM and 4.65 GB free space on HDD.
Thanks you for any suggestions
