Hey peeps,

for tweakers with knowledge, do you trust CPUID HWmonitor to give accurate per core boost clocks. My 7800X3D (running pbo and -5 offset on the 2 fast cores, -10 on the rest of them) regularly records a max on half or more of my cores of 5.6-5.8Ghz which seems comically high. I expect 5-5.1

Can anyone give me a little guidance (or a push to a site with reliable info) on what the per core VID should peak at and perhaps the other 3 VDDCR_VDD, VDDR_SOC, VDD_MISC (current maxes are 1.123, 1.240, 1.100)

I'm not looking for overclocking glory, I'm looking to slightly undervolt the cpu and get a reasonable return on what PBO can give it without stressing it and definitely without cooking anything.

If you have PBO enabled, it's auto overclocking so those numbers are correct. Single core loads will have one core go vroom and the others will hang back. This is normal.

Your best bet is just find what undervolt is stable for you. Not all chips are the same.

HWmonitor is known to be utterly useless, it has been for many years.

Use HWinfo, do not trust HWmonitor.

Mussels - thanks man, I really felt like I was looking at something odd.

Side note, when it loads and it scans the PCI bus it makes everything on the pc stutter for 2-3 seconds. That's a bit of a worry.

That can happen from many softwares, if you have any mechanical hard drives or CD/DVD drives it'll be those waking up that causes the stutter

SSD only, nothing optical and no spinning rust.

7800X3D is hard locked to 5.05 GHz unless you BCLK overclock.

AMD bclk OC can only go a BIT higher, whereas eclk can get much higher. HWBOT.COM is a good starting point for values for a 7800x3d overlocked system. Under ranks for any of the CNE benchmarks, user post validations of cpu-z and hwinfo photos of their settings for voltages and frequencies.

Minutes after this, i saw a post on facebook

11GHz i5


Hwmonitor is indeed, just trash.
