I did not do any changes to PBO. Just Memory Clock/Timing/Voltages
Maybe it's time, PBO Limits to AUTO not Motherboard, scalar 2x not 10x Curve negative - Allcores, maybe your cpu can't handle Motherboard settings, see what happens next.

From what Memory Clock/Timings you posted last time, it seems CL30 with RCD 36 from CL36 & RCD 38 Expo from fabrics, were way to much enthusiastic to work, why are you not tried first CL32-38 GearDisable
Yeah, cuz lazzier Gear Enabled from BZ it won't work

Also keep in mind not all Expo fabrics work well out of the box.
Don't be surprised, why not to work better on pure
1T GearOFF? 🤔
Of course you have errors.
Thats was more than clear from the beginning, if you build your foundation with GDM ON.
GDM Enabled hides issues. Always. Too much. Failures was expected, soon or later coz of that.
Gear ON act close
2T like putting a bandaid over them
GDM enabled does everything 2T would do, if 2T could be set with GearOFF like back times in Zen3 era, now you can't, plus makes it impossible for CS/CAD to land on odd clocks.
Start removing that GDM, you are just fine 6000C36 if you better focus stabilizing it, but if it was so easy, you would have already found it suggested from Luxx'ers.
Don't pick up the easy give-up route Enableing.
Accepting defeat tho GDM Off, won't make your issues go away.
Its not tooo hard. Come on. Please work harder ~
