Jim,
Yes, it is all on the same hardware.
Yes, there is adequate CPU cooling (there wasn't initially so I installed a new heatsink with thermal compound). Motherboard
monitors and it runs around 45-49 deg C. (MB temp runs about 35 deg C)

It is certainly worth a try (tomorrow) to lower the speed and see if it improves the installation.  Right now, I don't remember the
CPU speed x multiplier settings in use.

thanks for pointing something to try (tomorrow).
