has anyone made any adjustments to the voltage or frequencies and wish to share them?
And also I seem to be getting a lot of HW Errors is this normal?
I'm fairly new at this so any input will be appreciated

Yes this is normal. The number of hardware errors does not really matter, just keep an eye on the HW % on the top box. Even the best units wont have anything less than .5% errors. As long as its under 2% your fine.
