Comments

The Stilt commented on own score:

– FX-9370... On FX-9 series standards = Ultra low leak On FX-8 series standards = Ultra high leak Real core voltage = ~ 1.93V (1.475V + 0.45V offset) under load, UD7 does not seem to report anything accurate for CPU voltages or temperatures. Mods on board: - Slow Mode (a physical switch, check the picture), took 1.5 hours just to find the trace... - NCC PSE (560uF) series polymers in VRM loop 2 (CPU) replaced with FPCAP 10K 820uF caps. The additional 2600uF of bulk seemed to help...

Congrats! You're the champion. Had a lot of problems, otherwise could eventually beat you at AM3 32M, but only there...

I'll post some pictures when I have rested a day or two.

The "Slow Mode" is quite simple as you only need to connect a switch between PROCHOT and Vss.

It was a struggle to find the soldering spot for it thou, took around 1.5 hours.

I think the UD7 could do even more after the VRM switching frequency is raised.

There is no public datasheet for the ISL6330 so I don't know which pin sets the fSW or what it currently is set to. Usually GB boards have a very low fSW, on 990XA-UD3 for example the VRM operates at 263kHz.
