I recently built a new Ryzen 7 1700 system.

I had been just using the stock speed for a couple of weeks and things were going pretty good. I noticed in Windows 10 task manager the CPU speed would fluctuate in what I assume was a way to reduce power consumption when the CPU wasn't under load.
Today I ran the ASUS auto tuner application and it increased my CPU speed from 3.0 GHz to 3.65 GHz. Nice little bump I thought. However, I notice now that under the task manager the CPU speed no longer fluctuates. It pretty much stays at 3.64 GHz.
Is this normal once you overclock a CPU for it to stay at one speed? Is that a problem?
Also, my motherboard (ASUS Prime B350 Plus) came with a slightly older BIOS date back to 5/2017. I had just been running with that BIOS as it seemed to be working and at the time I didn't want to risk trying to apply a BIOS update it risk it failing.
I have some 64GB G.Skill Ripjaw V 2400 DDR4 (4x16) memory that I had been running at 2400 using DOCP. I had tried to push up the memory speed but kept running into stability issues. I could get 2666 if I pushed the voltage up to 1.35V but I wasn't comfortable doing that so I went back to 2400 @ 1.2V.
Well, I finally updated my BIOS to the latest on the ASUS site and decided to retry increasing the memory speed. This time I was able to increase it to 2666 and am now running at 2800 (so far without issue). This time I didn't have to touch the memory voltage and am still running at 1.2V.
Is that normal? Can a BIOS update make that much of a difference in memory stability or am I doing something wrong and somehow fooling myself that I'm getting a boost at the same voltage without changing any timings just the memory speed?
(Edit: Tried to bump up the RAM to 2933....and there be dragons!....failed to boot into windows....prompted me to reload BIOS from USB....managed to get back into the BIOS and reload optimized defaults...3.0GHz for CPU and 2133 for memory....first time I had ever seen that BIOS reload prompt....normally takes me to an American Megatrends BIOS screen prompting to press F1 to reset BIOS after detecting failed overclocking....anyway, think I'll run with 3.65 GHz and 2800 for the memory for a while)
