the ryan z 7 5800x does not maintain its optimal operating frequency
So in short, I adjusted my Ryzen 7 5800X manually to 4.6 at 1.36V, but it didn’t cause any issues during Cinebench R20 tests or games. However, when gaming or using CPU-Z, the readings jump from 4549 to 4556—not the expected 4.6. I’ve noticed this inconsistency with other CPUs; in my past experience with CPU-Z or Rivatunner monitoring, the correct overclock values were visible. What’s going on with the voltage limits?
What you are observing is "Effective clock" and it means identical to a single-core processor. That's how Ryzen operates, once one core approaches full capacity, another contributes to the workload. Only when you run at maximum single-core performance will you notice the peak frequency.
What you observe is "Effective clock" and it means identical to a single-core processor. This is the principle behind Ryzen, where once one core approaches its maximum capacity, another core contributes part of the workload. Maximum frequency will only become apparent when running applications designed for a single core, which are typically benchmark tests. Another factor might be related to BCLK (FSB) not maintaining a full 100MHz but fluctuating slightly below that level.
Use a suitable monitoring tool to observe the actual situation...suggest HWINfo.
I would not run that high voltage. To figure out your max voltage, do the following (paraphrasing ShrimpBrime but it's also recommended by Buildzoid):
'In BIOS, Enable PBO, everything else on auto. Run Prime95 128k (both boxes) FFT with in-place unticked. (torture test) The SVI2 TFN (v-core) reading in HWInfo 64, what that reads, that is your fitness voltage.
The FIT voltage is your chip's safe voltage. Manually overclock frequency to this only. Going above is when you risk degradation.'
With a static overclock, the safe voltage you want to hit will be the same in Prime95 128k FFT.
