Just done a little flight in the 172 up the east coast of England.  I had HWMonitor app running alongside to monitor cpu speeds and temps.

On completing the flight I was extremely surprised and shocked to see most cores on my AMD 7800x3D hitting max speeds of over 5.5 Ghz with 3 cores showing a whopping 6.907 Ghz.

I do have a negative curve optimiser set in the BIOS at -30 and temps capped which does gain me better performance and higher scores in Cinebench but I have never seen speeds like this before.  I have no idea how long they peaked at these speeds.

 

Any thoughts guys?

these GHz values are definitely fake. I assume your benchmark tool is outdated and not fully compatible with the 7800X3D chip.

if you super cooled a CPU using liquid helium or liquid nitrogen, you can go up to 9 GHz for some 3 minutes, but no way at room temperatures, otherwise we all would be running our 7800x3Ds at 7 GHz. 😀

I suggest using the original AMD Ryzen master tool.

App installed 2 days ago after a system format. Was a fresh download and recognised as one of the leading monitoring tools

ok, lets all trust some fresh freeware tool instead then and enjoy 7 GHz.

AMD's very own Ryzen master tool will show you exactly what your cores are running at, but hey what do they know about their very own 7800x3D CPU max clock rate of some 5 GHz. 😀

there is no way a 7800x3D core would run at 7 GHz at only 63 celsius without some form of super cooling (liquid helium/nitrogen).

You should run it on 3DMARK you will have no problem knocking the pros off top spot. And 3Dmark will authenticate your system if it legit.

HWMonitor definitely isn't a leading monitor tool these days, it is known for being inaccurate and throwing up erroneous readings. Seen multiple threads on Reddit about your situation. 

Use HWiNFO instead.

Normally it shows max core speeds between 5 and 5.2, when the curve optimiser is enabled. I know the figures in my screenshot are crazy. Wasn't sure if perhaps it spiked for a second. Perhaps due to the CPU BLCK figure going to a max 136.8

I’m sure a lot of people will spend some serious 💵 💰 on an air-cooled 7800X3D that boosts up to 7GHz 😀

Haha it is water cooled but clearly there was a mis reading of the core speeds

You can simply crosscheck frequency/temperature and power consumption. That frequency, running so cool even if watercooled, with only 80W of power draw, something is wrong with the reading for sure.
