Maddening Audio dropouts are back Cubase 9.0.3

The audio dropouts are back…

Is there anyone who can help interpret Latencymon results for me? Most of it is Greek to me. Again it suggests I disable CPU throttling. I have power management set to high performance mode, and am pretty sure there is no SpeedStep or any other kind of CPU throttling enabled.

It also warns me that CPU speed “Reported” is 3109 MHz, but “Measured” CPU speed is only 1 MHz

I ran CPU-Z and it shows core speeds jumping back and forth between 3108 MHz (x 31.00) and 1604 MHz (x 16.00). What does this mean, and is it relevant?

This is driving me crazy (and costing me a lot of business). I’m thinking about getting a new computer, but if I don’t know what’s wrong with this one, how can I be sure I won’t just recreate the problem with a new one?
