A neat feature is the 6 temp sensors in various spots on this board. Though I've yet to find software to see them but inside the BIOS.
VRM was ~37C when I first booted and cpu 33C~idling.
I've yet to see any stability issues. My windows sadly needs to be reactivated, windows servers seem down so can't do it right now.
I ran some Memtest in windows and they went through 1 round of all memory without errors, my Corsair LPX 2666C16 works like a charm.
It's late today and this has taken a toll and I'm really tired.
Found gigabyte app that shows the temps
Running some Prime95 blend or smallFFT, VRM reach 60C+
3200Mhz ~1.1volt (all auto settings, not under load 1 cpu constanly boosts 3750Mhz with 1.380volts, so voltage goes down under load...)
