out of your computer, It is also easy to do. But please follow anti-static precautions as
memory is very sensitive to static electricity.

Notes:
- Here, "memory" refers to Random Access Memory (RAM), not to Hard Disk
Drives. RAM capacities are usually measured in megabytes (MB),
hard drive capacities are usually measured in gigabytes (GB).
- This is a 168 pin stick (approximately 133 milimetres long).
Please check that your motherboard's slot is long enough to accomodate this type of
memory. (If the slot is not the same length then your motherboard supports some
other kind of memory, not SDRAM.)
- There are two notches on the stick. If you look at the picture
above, notice two breaks in gold pins at the bottom of the stick. Please check that
your motherboard has the same number of corresponding ridges. (If there is only one
ridge, and the slot is of around the same length, your motherboard supports DDR memory,
not SDRAM.)
