I believe what peterh meant was "free up memory" not as you have understood "free memory." It would be helpful to know the kind of motherboard you are using so that you can be better helped.
In any case, your motherboard has a graphics chipset integrated into it. It may or may not have video memory as part of the chipset, but when it needs more memory to run higher resolutions, it borrows memory from your RAM. What peterh is suggesting is that if you put in a graphics card with its own video memory into a slot of your PC, it will not need to borrow RAM from your system. In this sense a new graphics card will "free up" the memory that was once used by your inboard graphics on the motherboard.
Here's the problem - peterh has suggested that you purchase an AGP card, but we don't know how old your motherboard is. When you look at the slots on your motherboard, especially on older boards the AGP slot is usually brown. On really old boards, there is no AGP slot. On less old boards there is an AGP slot but it may only support 1X or 2X boards. If this is the case, you would want to buy a PCI card. If it can support 4X, you can use most of the AGP graphics cards available.
Your motherboard has a limit to the amount of memory it can hold and each slot has a limit as to the size (64K, 128K, 256K or 512K) of the stick. If you know the kind of motherboard you have, you can usually find these through a Google search. On old motherboards (BX types), in general there are three slots and each slot can carry a maximum of a 256K stick. Again, while this is typical of an "old" board, each manufacturer configured them differently. There is a difference in the kind of memory DIMMS, SDram, etc. That too is specified per board.
Hope this helped.
