By comparison, your DS10 is a hot rod vs my two.  I have a "stock" DS10 617MHz and another that is a DS10L 617MHz mainboard I transplanted into a regular DS10 chassis.  Both VUP out below half of your figure.

Stock DS10:

$ @wasd_vups
AlphaServer DS10 617 MHz with 1 CPU and 2048MB running VMS V8.4-2L1
INFO: Preventing endless loop (10$) on fast CPUs

Approximate System VUPs Rating : 331.4 ( min: 329.4 max: 332.8 )

Upgraded DS10:
$ @wasd_vups
AlphaServer DS10L 617 MHz with 1 CPU and 2048MB running VMS V8.4-2L1
INFO: Preventing endless loop (10$) on fast CPUs

Approximate System VUPs Rating : 325.8 ( min: 324.6 max: 327.0 )


I wonder what the difference is.
