Sampling/Polling Interval?

Hi ... due to the much publicized Vmin shift instability for Intel's 13th/14th gen processors, I need to monitor the maximum core voltage or VID to ensure it never exceeds the thresholds I've set in bios or Intels 1.55v recommendation.

Does the displayed Core VIDmax value depend on the window sampling or polling rate? Can the program miss a VIDmax value because the polling rate was too slow or do you internally poll much faster but only display the values as determined by the polling rate? My concern is that the CPU requests a value that could exceed recommendation specs but HWInfo misses it because the polling rate is too slow.

I have currently set the rate to 100ms but it eats up quite a number of clock cycles on 2 P-cores (utilization between 90% -100% on both processors). Is it possible to reduce this overhead somehow (i.e., without using a lower polling rate)?

I have an ASUS z690 TUF-Gaming 128GB DDR4 mobo with 3600MHz ram with a 13900K CPU.

Thanks,
David
 
Yes, sampling of VID/Vcore values depends on software (Windows) sampling rate. And since the hardware change rate is always faster than any software can catch, it can miss several spikes.
You might try to disable unnecessary sensors and use the latest (Beta) version 8.11, which has several improvements for sensor polling and should reduce the load at higher rates.

Another alternative would be higher-end ASUS boards that support the Vcore Latch (VLatch) feature. This is a dedicated voltage monitor embedded in hardware that monitors voltage in real-time and catches all min/max spikes. It's well supported by HWiNFO.
