<P>This is a 512MB EDO DRAM Memory Module for your Compaq ProLiant 5000, 6000, 6500 & 7000 series server. RAM enables your computer to complete tasks more quickly, using this memory to hold data for processing instead of using the hard drive, which causes the majority of processing slowdown. The addition of 512MB of RAM means your ProLiant server will be running faster than ever, and able to take on any heavy tasks. </P>
