Hmm, that's Kingston RAM. Are you absolutely sure it is compatible? (I advocate using HP RAM in HP servers)
What was the old RAM configuration?
I'd suggest going back to the old configuration...
To start, please remove power (and power cables) from the system for a few minutes. Plug them back in and try again. Also, is your ILO3 configured? You can use that to review the server's IML log and see why your RAM is giving you an error or any other relevant POST messages.
For the new RAM, please ensure it is seated properly. The DL360 G7 has 18 DIMM slots, so you're filling it up. Weird things happen when you approach the limits of a platform like this. So the best case is to start small and popular one DIMM per CPU and build up from there.
You're using unbuffered RAM. That server will only support 96GB of unbuffered memory... so 12 modules.
Please use the right RAM for the server (500662-B21) if you intend to max the server out.
