Is it safe to use a 6800k processor with 4.2ghz and 1.31v voltage under 66c?

It appears the distinction between Balanced and High Performance settings is quite noticeable. I’d like to see more frequent boosts. Is there any option to bypass the stock clock? Currently it looks like this:
Balanced mode
*Idle* 1200 MHz
*Start Render* 3400 MHz (Stock)
*Occasional points in the render* Cores 2 and 3, 4200 MHz briefly.
These seem to cause slow rendering.
High Power Mode
*Idle* 4200 MHz but low temperatures/low usage in Task Manager.
*Start Render* 4200 MHz
This results in much quicker renders.
Are the actual render times significantly improved? The issue isn’t about clock speeds themselves, but rather with the software not sufficiently utilizing the CPU.
I would prefer things to be simpler, but yes they are significantly quicker!
It’s a fairly short and heavy render; it takes 7m15s at 4.2ghz High Performance... and over 9m30s in Balanced mode. I gave up around 80%.
In my view, the issue lies with the rendering software in Balanced trying to move slowly. On High Performance, it seems to rush through a fast stream.
I’m considering testing the Balanced setting at lower percentages—like 50% and 100% (currently set to 5% low and 100% high).
It’s odd that despite consistent 4.2ghz clock speeds, voltage stays steady at 1.315v, but the Task Manager shows only 0-5% CPU usage when idle, with temperatures around 25°C. That clearly changes when I render or stress test.
I also ran some benchmarking:
At stock settings:
4221
19627
OC High Performance (constant 4.2):
4753
21993
OC Balanced:
4300
21920
It looks like single-core performance stays at stock, while multicore maintains the correct speed?

The gap between Balanced and High Performance is quite noticeable. I’d like it to increase more often. Is there a way to bypass the stock clock?
Right now it seems like:
Balanced mode
*Idle* 1200 MHz
*Start Render* 3400 MHz (Stock)
*Occasional points in render* Cores 2 and 3, 4200 MHz briefly.
= Slow renders
High Power Mode
*Idle* 4200 MHz but low temps/low percentage shown in Task Manager.
*Start Render* 4200 MHz
= Much faster renders.
Are these really much quicker?
The reason you aren’t reaching higher clock speeds isn’t about the clock itself. It’s more about the software not demanding enough CPU power.
It's odd, I haven't experienced those kinds of performance improvements in high performance mode before.
It's less of an improvement in High Performance and more of a restriction in Balanced. During render load in Balanced, it really has trouble maintaining above 3.4ghz, often staying far below that most of the time. Disappointing! I think I'll just change to a different mode for rendering. For regular use, if I keep Balanced mode but keep CPU usage low—say around 75%—so it consistently runs at least 3ghz instead of dropping to 1.2Ghz, are we considering a shorter lifespan? If so, that’s fine as long as it lasts about 3 to 4 years instead of 20.
When your CPU isn’t running overclocked speeds, it will perform just as long as intended. You can typically expect around a decade from its lifespan. Make sure you haven’t altered anything in the balanced power plan—your 4690K at 4.5ghz maintains full performance even during moderate loads of 40-50%.
