Need help with HP ProLiant ML 150G6

[eth10747]

So I have a HP ProLiant ML 150 G6 server desktop, and its missing some parts- I got it from a friend. I does have a power supply, and it has 2 CPU sockets, one of them is already in there, need to find out the other one, but I don't know what CPU it is. I have no ram whatsoever, So I don't know what kind of ram I need. and there is no hard drives in there, but I can supply that assuming it works with any hard drives to date. I think there is 12 ram slots. Any help would be greatly appreciated.

Google is your friend: "ML150 G6 Quickspecs" -> https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c01710806

You write that you already have one processor inside and you don't know what it is... Why not remove the heatsink, wipe the thermal past away and read the chip type?   :-)
