Woohoo! We're back. Thanks to @xkm1948
, I'm back in my happy place (that is, a 4.375 OC, 125 x 35) at DDR4-3000 using BIOS 2101.
Here's what worked for me thanks to the guys above:
1. Power off, pull power cable
2. Move the CLRTC over
3. Wait 10 secs
4. Move the CLRTC back
5. Power up, enter BIOS
6. Set overclocking to XMP, select the only profile I have (DDR4-3000, 1.35v)
7. Set ram voltage to 1.36 (may not be needed)
8. Set VCCIN to 1.905 (the board rounded it to 1.910)
9. Change SA from Auto to 1.18 (I chose dead in the middle from the numbers m0n4g3 posted)
10. Save and exit
At this point the machine powered off instead of rebooting but that's back to the way it was before I moved to 2101 so I'm used to that.
Ran Prime95, no problem,
Ran RealBench and came up with 100,641. That'll do for now until I can get back to pushing the OC.
Glad you guys and this forum are here!
