Pentium 4 comptability with SD Ram

If you know what mother board you have you could check what RAM it can use.

All RAM is installed in the same way, but different types of RAM are keyed differently. That basically means that one type of RAM (for example SD RAM) will simply not fit into another type of RAM slot (for example a DDR RAM slot).

To install ram on a PC
Please note - do NOT touch the connector side of the RAM, handle it only by holding the side or top edge
1. check that you have the right type of RAM. do this by lining up the RAM above the RAM slot and making sure that the RAM is the same length as the RAM slot AND ALSO that the RAM's key (the little hole or notch in the RAM) lines up with the key in the RAM slot. Note there might be more than one key
2. open both clips of the RAM slot by pushing them down and out from the center of the RAM slot
3. gently insert the RAM into the RAM slot
4. check again that the RAM and the RAM slot's key's line up, if they do, firmly press down on the RAM on both corners until both clips automatically click shut on the RAM

That's it! :-)
