Z600 CPU support and motherboard revisions

Good day! Reread all the posts about the version of HP Z600 Mb, but could not understand exactly what version of my Mb. On Mb 2 CPUs are installed: Intel Xeon E5606, 2.13 GHz/8M/4.80. Will two Intel Xeon x5675 processors be able to run on this Mb? Photo site Mb attached. I ask for help from specialists. Thank you!
