Hi Ken,
one physical cpu modul contains 2 CPU cores, so if your system tools like "ioscan -fnCprocessor" or "/usr/contrib/bin/machinfo" returns you have a number of 4 CPUs, you can add 2 more modules and will have 8 CPU cores.
Hope this helps!
Regards
Torsten.

whooa there!
Yes the rx4640 can have up to 8 CPU 'cores', but it only has 4 sockets.
The only way to get 8 CPUs (cores) is to use HP's mx2 module which combines 2 1.1GHz Itanium 2 processors onto a single socket (note this is 2 seperate pieces of silicon, NOT a dual core processor).
As Ken mentions he has 1.5GHz CPUs, we can surmise that he doesn't have mx2 modules, as they were never available at that speed, which means he has 4 single core modules.
So if he wanted to go to 8 CPUs, he'd have to rip out all 4 processors and replace with 4 mx2 modules. Not cost effective and unlikley to give much of a performance uplift, as the dual processor mx2 module is not that much faster than the single 1.5GHz processor.
At the back end of this year Intel should release true dual core Itanium processors - at that point an upgrade might be worth thinking about, although it would still require Ken to rip out the 4 existing processors.
