Yes, under Advanced -> AMD CBS -> UMC Common Options -> DDR Options -> DDR RAS -> DDR ECC Configuration. Options are Auto, Enabled, and Disabled.Check the BIOS if it has an option to enable or disable ECC functionality.
Also yes, one level above the previous. Options are Auto, True, and False.Check the BIOS if it has an option like "Disable Memory Error Injection" which can be set to "False."
This is in two different places, one is Advanced -> AMD Overclocking -> Precision Boost Overdrive where you can put in manual entries for PPT, TDC, and EDC the other is under Advanced -> AMD CBS -> SMU Common Options where you have "TDP Control", "PPT Control", "Thermal Control", and a few others. Not sure which setting takes priority over the others.Please check the Overclocking section of the BIOS, see if there's a way to cap max power usage, e.g. at 105W, 90W, etc. These CPUs underclock well, so this could make your 12 cores or a 16 core more useable WRT thermals.
Also, to answer my own question from Patrick's article, there is an option for bifurcation of the PCIe x16 slot. This is found in Advanced -> AMD PBS -> PCIe/GFX Lanes Configuration. Options are x16, x8/x8, x8/x4/x4, and x4/x4/x4/x4
EDIT: To keep others from beating their head against this issue as well, there is a BIOS setting that has to be used to keep system output using the BMC VGA port (and the HTML5 console if you're planning to use that) after leaving the BIOS:
Advanced -> AMD PBS -> Graphics Features -> Primary Video Adapter: "Ext Graphics (PEG)"
