Can I use curve optimizer and offset undervolt at a same time?

[CodeError]

Last year I bought AMD CPU R5 5600X. I done some test and everything was fine. I don't game too often, this summer I played Helldivers 2 and temperature was going to max 85C. Room temperature was also high, around 34C. Now temperature in Helldivers 2 are in low 70C - room temperature 24C. Yesterday I done some test in 3DMark and I noticed that clock frequency now have lot of oscilation but benchmark score are the same.

Spoiler: Old tests - One Year ago

Spoiler: New tests - Yesterday

1. Why does clock frequency tend to oscilate now but before one year was stable?

2. Curve optimizer increases perfomance but also temperature. Can I use at a same time curve optimizer and offset undervolting? I would try these some combinations and put BIOS settings and benchmark progress here.

I can test stabillity in 3DMark, OCCT or any other program you want.

If this is a stable setup for 1 year, you probably better off NOT making any changes and just enjoy the rig. Minor differences in PBO say 50 to 100mhz increase or decrease won't have a very large impact on benchmarking and gaming 3D.

The fluctuation is the CPU running where it needs to be, probably based on background tasks that may have been implemented through time via windows updates and user installed applications.
Generally to overclock it requires more power and not less. Of course this depends on temps and overhead, PBO only gives 200mhz increase either way, otherwise you run a static overclock.

It looks good, I wouldn't change anything.

Depends of the board though. My Crosshair VII for example can give moar than 200MHz.

CROSSHAIR VII !!! So can give more, but what is the limit? And is that with a 5600, or it doesn't matter what cpu is installed?? My kids 5600G and ROG B450-I only allows 200mhz, but of course that's all I have to compare with.

I'll check on next reboot. Though I use the 200MHz option as it gives up to 5.05GHz on my 5800X.

5600X isn't likely to hit some 5ghz even on that board lol.
