I added to sticks of 512 MB of RAM in to an HP Compaq and during boot I got the message "219 ECC Memory Module Detected." When I removed the Samsung 512 MB (PC3200) stick the computer booted.

Thanks in advance

I have seen some of the brand name computers that require you to go into the bios, and basically confirm that new memory has been added.  It could be something as simple as that.  It may also be that your system can't handle that size memory stick.  Is this a newer machine or a little bit older?

What it means is that the computer can not use ECC registered memory.  You are going to have to purchace Non ECC or non parity memory.  ECC memory just can not run on an HP computer.   You should go to  This site will make sure that you get RAM that is compatitble with your computer.
