No it is tweaked for their own workstations. So in theory to get the best out of a HP P600 you would use it in a HP workstation specified for the model.
Generally speaking a PNY would work fine but you may not get support for it in a HP workstation or vice a versa = why is it not working? well you should have bought the HP version / or is this hp p600 card is not working in my workstation? well you should have bought the PNY non specific version.
