As I have no experience to share on Nano, I would do what I did when making ROM for @ENTERPRISE
on his 295X2.
I am explaining as your +20% using Overdrive / MSI AB.
I first increased TDP same as say stock +20%, as clocks still dropped I upped MPDL by stock +20% as well, clocks still dropped, I then modded TDC only by little amount as well, my first effort on TDC was successful
Do it in stages like above and you will be fine IMO, just don't do TDC +20% straight away. Also be aware as these new values will become starting point, if you add "PowerLimit" using Overdrive/MSI AB, etc you will be going higher.My Vapor-X 290X has all these mods in ROM (Click to show)
- Stock GPU/RAM 1030/1325 boosted to 1100/1525.
- GPU Freq. DPMs 2 to 7 boosted per % as in OP heading Making OC bios like factory pre OC'd card/ROM.
- VRM Controller reprogrammed to remove +31.25mV VDDC offset and - 6.25mV VDDC/VDDCI offset.
- 3 States VDDCI (150MHz@0.850mV 1250MHz@0.925mV 1525MHz@1.000mV).
- GPU Clock 2 matched to DPM 2 GPU Freq.
- Mem Freq. DPM 1 & 2 @ 1250MHz.
- All DPMs manually voltage fixed and tested.
- Efficiency @ idle table matched to DPM0.
- 390/X Memory Controller Timings.
- Timings improved for straps 1250MHz & 1375MHz to Stilt's AFR.
- Timings improved for straps 1500MHz & 1625MHz to Stock 1250MHz AFR.
- Standard fan mode Profile improved for clocks/voltage being run.
- TDP 238W MPDL 238W TDC 229A
Recently I did a 70hr+ continuous f@h run, no errors
, it was in my Q6600 rig. I lowered OC on CPU due to a) increased temps in case from VX290X vs HD5850 b) in a cheap Fractal Design case, it used to be in my modded SilverStone but now i5 in that.
Average column in HWiNFO will show drops due to when CPU/GPU idle when finish unit and upload/download occur.Main f@h screen with HWiNFO (Click to show)

I sort of understand you calling it bug but they are maintaining that value as it was in past (I hope I make sense).
What I think should occur is:-
a) better description of value in Overdrive, say like a helper balloon or something relevant to bios/GPU
b) they should show the new value as well, with perhaps another title / description.

, I only got better profile when I added at least 150% to it and also changed the new value.
