The Provost is helping you with what processors are officially supported by HP for Z820 workstations...... note that the two Z820 QuickSpecs are early and late in the Z820's evolution.


As is the case with the Z400/Z600/Z800 series of workstations the ZX20 series also has an original and a version 2 type.  Those two versions can run different processors.  Generally the version 2 workstations can run all the processors that the version 1 could, plus a more advanced group of processors. The way to tell what you have is by going into BIOS and on the first page seeing what your "Boot block date" is.


Then you can look in this forum for what version you have, and use the appropriate QuickSpecs document to see the list dependng on whether you have a version 1 or a version 2 workstation.


The processor you present, the X5660, works fine in the version 2 of the Z600 and Z800 but cannot run in a ZX20 series HP workstation because the processor generations are different (as are the sockets).


My optimized Z600 version 2 workstations use two of the fastest hexacore (or two of the fastest quadcore) processors HP listed in the last version of the Quickspecs for the Z600 (QuickSpecs version 51).  These Z600s can hold their own up against the Z640 workstations we are buying now at work.  Of course, the Z640 has much more headroom for speed if we spend a lot more, but when comparing my souped up home Z600 version 2 workstation to our work Z640 workstations they are near equal in performace.  Quite unequal on net cost, however.
