I will get a new batt for my multimeter and do some measureing for you guys.
My S7 is running stable at 4.8 at 600. Power at wall 1180. Using a RM1000 and a RM650
Mine only got to 4.7 at stock speeds. But at 612, it averages 4.8 and is very stable. After increasing the frequency the HW errors went up a bit from 0.0222% to 0.0386%, but that's still fine.
Overall this unit is very stable and predictable. I just wish they could have shipped the rest of units that I ordered before getting plastered on baiju for a week
interesting. on my machine:
600 starts OK (4800), then rumps up slowly over 12 hr to ~4840 <=0.006% error
606 starts good (4900), then slightly declines over 24hr to 4886 and stays there (5 days) 0.0068% error
612 starts super (4990), then decreases to 4915 over 24 hr (maybe would have kept decreasing, basically negating the higher freq) 0.0088% error
strangely, at all frequences board temp are 52-53C (fluctuating between 51C and 55C)
Conclusions:
1. it takes a long time to truly settle (>24hr), so I suggest to not reach a conclusion based even on 1hr as it might change.
2. temp do not depend on frequency much (this is strange), but probably correlate with ambient air temp (mostly).
