Overheating A10 5800k CPU on a F2A85-M Motherboard

I've noticed a few discussions on this very problem on a number of forums but none really get to the bottom of the problem.  Some people speculate a persons replacement heatsink didn't have the right amount of thermal paste, others suggest all manner of other potentials.

I've been observing this problem for a while, it's been since a few changes in AMD driver updates and a BIOS update.  I think I've finally got to work out where the problem is.  Asus's motherboard tends to try to optimize everything to run at it's fastest, unfortunate when it boosts everything to do that, it both increases heat and destabilises the computer as a whole. 

I'd been humming and harring for a while wondering about which setting to try and I'm pretty sure that I've worked out the solution for this particular CPU and Motherboard combo.

Firstly make sure that you have the most recent BIOS firmware for the motherboard installed.
In the settings of the BIOS there is a DIGI+ VRM setting (Digital Voltage Regulation Module)
The important one here is the CPU Load-Line Calibration, It defaults to [Auto] however it's best to reduce it to [Regular] this will reduce your upper clock speeds but reduce your heat Package/VRM temps and voltage usage.

This will reduce the crashes caused by the Package/VRM temp's spiking from all cores dumping too much heat.

Sounds somewhat reminiscent of circa 5 to 6 years ago when differing answers began to be suggested for solving the quirks of Dell's Optiplex 755. AFAIK, only one difficult-to-find place on the web publicly offered the solution slash nailed the true source of the problem; and unlike here, it's not even presented in a forum thread. May not have originated in any of the many discussions back then that tried unsuccessfully to remedy the 755's issues for good (as largely suggested by experts who didn't actually own that desktop): http://www.rtr.ca/optiplex755/

Just an update on how stable my system has been since the fix I mentioned in the initial post. I've not had any unplanned reboots caused by the CPU over-exerting itself, which meant the fix I worked out did actually work the way it was suppose to.

Further Update:
The system is still stable.  I just need to work out how to reduce the dust intake and stop it clogging up my fans :/

Further update:
System has still been stable ever since that setting change.
