Nope. Software doesn't know that much about hardware in this case. NEO2 has no voltage regulation and H5 is fed with 1.1V which limits maximum cpufreq on this board to 812 MHz (maybe 864 MHz). FriendlyELEC learned from a conversation with open source community that with mainline kernel they could make use of DVFS (dynamic voltage frequency scaling), something that still seems not possible with Allwinner's BSP. As a consequenze they dropped Allwinner's software offerings, rely on mainline u-boot/kernel now, have DVFS working and even re-designed a few H5 boards to implement better voltage regulation (eg NanoPi M1 Plus 2, NEO Plus2 or the new NEO Core2 which are both equipped with an I2C accessible voltage regulator).   What limits cpufreq is DVFS (the higher the clockspeeds the higher VDD_CPUX voltage provided). With NEO2 you're out of luck since this board remains at 1.1V all the time. All fixes in software (adjusting cpufreq OPP or thermal trip points) will only result in instabilities, freezes, crashes but not in higher performance. It's slightly larger sibling NEO Plus2 can switch up to 1.3V (~1200 MHz) and M1 Plus 2 as well as NEO Core2 can theoretically be fed with +1.4V which would allow for slightly higher clockspeeds (increasing temperature and consumption a lot).   On small boards like these NEOs this is of course absolutely useless unless since heat dissipation is a huge problem. Without huge heatsink(s) plus additional fan(s) don't think about running any load at 1 GHz clockspeed or above over longer periods of time (read as: few minutes).
