With the VUPS.COM procedure modified to

|$ cpu_multiplier = 10 ! VAX = 10 - Alpha/AXP = 40 $ if 
|f$getsyi("arch_name").eqs."x86_64" then $ cpu_multiplier=8

the resultant

|X86VMS$ @vups.com
|innotek GmbH VirtualBox with 2 CPU and 7574MB running VMS V9.2 
|Approximate System VUPs Rating : 225.6 ( min: 224.4 max: 226.2 )

down from 272 "VUPs" reported previously, on a commodity DELL SFF with Windows 10 Pro Version 22H2

Processor	Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz   3.60 GHz
Installed RAM	16.0 GB
