Vcore discrepancy question Z490 10 Series OC guide

For the last several hours I'm making through the NickNs Overclocking Z490 10 Series guide. I set everything exactly as per the guide, I read every word in it. Now I started with the first OCCT:Lin test and stumbled upon a big discrepancy and I'd like to clear it up before continuing with anything. In the guide there's a line: "Real Time Vcore OCCT:LIN 1.190v - 1.195v could be slightly higher or lower". My real time Vcore is mostly at 1.279 and max is 1.288 (when I took a picture I'm attaching it was by chance at 1.288). That's almost 0.1 above what it should be. That probably doesn't fall into "slightly" category, or does it? Also, my temperatures are around 80°C so I guess I lost the lottery big time. Again, this is the absolute first test in the guide for 5GHz no HT. I ran it for 20 minutes without errors but then decided to stop because of this high Vcore number. My question would be what does this mean, is it bad or can I do something about it?

I have not gotten to where you are at yet....so I cant help much.

The correct OCCT version is also important....not the latest...but the correct version!

It would be great of someone here has the same MB as you.

Yes I know....do I sound like I am blaming you?

ok checked.

0Artur0 -- The 1.288 Max VCore is not a problem at this point.  It is well below the 1.48v hard ceiling.  Your Max CPU temps stayed under 80C (79 Max).   At no time should real time Vcore spend anything but a transient second get above 1.40v.  

Understood!

Max voltages don't look too bad...a little high maybe. But there should be moments in LIN where the Vcore drops to 1.2V or so. Might need to check the Load Line Calibration setting? I have no idea if the same one should be used for the STRIX.

You weren't testing with HT back then

I'd have to agree with you here.  But 5.0 on all cores with Hyperthreading enabled is nothing to sneeze at!  That will be a solid performer for whichever sim you plan to use. 0Artur0 wrote: One more question regarding setting the Watts. Do I look at package temperature or a single core temperature? Package Temperature.   Round the 235.44 to 235.  You may still be able to tweak the memory and you still need to verify PCIe video adapter 3D load stability. (Step 9 in the Guide). If you want to go further you will need to address your cooling solution.

Thanks to NickN and the gang for this guide! It was very helpful.

All I meant was that if somebody with Strix motherboard attempts the OC following this guide to report their Vcore temps, so I can see if those discrepancies were due to different motherboards or something else. That's all.

I'm still monitoring the numbers when flying. I noticed that sometimes in HWmonitor the Min Clocks numbers show 800MHz. I didn't see the CPU at that clocks myself but I'm not observing the numbers all the time. When I look at it it's always on 5000 MHz but as I said, sometimes HWmonitor shows some or all CPUs at 800MHz Min - it probably drops for a short period of time. Is this normal behavior? I'm just asking because that's another new thing to me.

I'm not sure there is only a 2% difference between 100MHz clock speeds when a clocked 10900K HT and a higher quality video card such as a 2080ti or a 3080/90 card is properly being deployed with correctly organized NVMe/OS and memory speed/latency.
