This an old spare server I use for a Minecraft server and a web server.
It current has 2.5GB of RAM. I recently purchased 4GB (4x1GB) of new RAM and when I installed them, the server would not boot. The fan starts, and there are no non-green lights on the motherboard, but it doesn't actually boot.
The current RAM is PC3200 400MHz ECC CL3, and the RAM I purchased is the same, as far as I can tell. Is there anything I can do to get the server to boot? I've tried only using 2 of the new chips, and I've tried different combinations, but none of them have been successful.
Edit: I've just noticed that one of the current pieces of RAM is PC3200U and the rest just say PC3200, whereas the new RAM is all PC3200R. Is this a problem?

According to HP's documentation on the ProLiant ML110 G2 it doesn't support Registered ECC RAM, which is what you bought and are trying to install. You need to use Un-buffered ECC RAM, which is what you previously had in there.
