If you have empty DIMM slots, and if any of those nonfunctional computers have compatible RAM, you can simply cannibalize their memory sticks for your working computer.

Or, someone else may have leftover DIMMs on their shelves.

So, you -or your friend- need to find out:

[ ] How many DIMM slots does your chassis have?

[ ] Are any slots empty?

[ ] What denomination (capacity) are the DIMMs you have? (They may not all be the same)

[ ] What type of memory do you have (e.g., DDR3, PC3-12800)

[ ] What other types of memory will the motherboard accept? (Note the motherboard model number and check the manufacturer's website)

[ ] What is the memory capacity of the motherboard? (This is determined largely by the main chipset, e.g., X58 or Intel 5520)
