12700k Overclock - Higher DPC Latency Possibly?

[XLEK]

I updated my bios and went to change all my settings back to what I originally had but I came across an issue? When overclocking my CPU to 4.9GHz, which is what I originally had, my DPC Latency was .37 prior to the update but after the update it was around .4 DPC (I know its small but it got me confused). I went to task manager & bios and noticed that my base speed(TM)/frequency(Bios) still shows it at 3.6GHz BUT in task manager it will say the 4.9GHz speed(left side speed above threads), but 3.6GHz base speed(above cores etc.) to the right. So it got me thinking, did my bios update cause the issue or am I overclocking it wrong(I don't think so)? So what's causing the DPC increase? Now this is where it gets more confusing, when I upped the Overclock to 5.0GHz at 1.225v(1.18v for the 4.9GHz), my DPC went back to .37, sometimes .36 DPC, which is was expected since it was a higher clock but it should be lower since I had it already at .37 DPC at 4.9GHZ prior. But I did a stress test using 5.0GHz and checked DPC and it was going below .2 when it was being stress tested, then back up after the stress test? I don't know why it would go down when more is being used by the CPU(maybe someone can explain that)?

So the big question is, If my DPC is higher by .3 after the bios update on 4.9GHz and its only showing 4.9GHZ in one of the 3 areas I described above, could that wrongly displayed base/frequency speed cause some input DPC due to something misreading in bios or registry?

My Setup (All latest drivers, GPU needs latest):
Intel i7 12700k 5.0GHz(current after bios update) - (40c Idle)
ASUS TUF Z690 WIFI D4
Corsair Vengeance RGB Pro 32GB (2x16GB) 3600mhz 18CL E-Die, Timed at 14CL - (33c Idle)
MSI Trio 3090 GPU Overclocked (Core 2025MHz/Memory 9951MHz)-(35c Idle)
Samsung 990 Pro
NH-D15 Cooler
Trio Extension GPU Fan Cooler (Below GPU)
GPU Memory Heatsink + 2 Fans (Top GPU)
Marvell AQC113 NIC 10GB Ethernet Card
All Fan Settings Turbo/Max(GPU, Cooler, Case, Etc.)

All temps when playing Overwatch, Deadlock, etc. are all in safe, cool ranges and games run fine no issues.

Thinking about this for the fifth time still leads me to ask that you find a latency increase from 0.37 to 0.4 microseconds? 0.03 microseconds. Also this forum is blessed with the greatest people from both sides. No question can be made without proper information and no straight answer can be given by some reddit level geniuses but at least here are some nice screenshots of settings that don't show or compare anything relevant. That's how the task manager reads those values normally. At least send sreenshots of what DPC latency you're talking about and what tool you use.

Yeah, I know its very slight and I don't care about that and I know there's room for error etc. I use LatencyMon, which again, I know that isn't reliable as the Microsoft one. But after starting latency mon for multiple consecutive days with the same starting DPC, then I make the bios update, numbers different for frequency and speed, DPC increased (yes slightly), I just thought I'd post to see if there was an error in bios I did or if there was a fix to show the numbers displayed how they were prior to the update to see if that can fix it. I send pictures of comparing anything because these are the same exact settings I was using prior but maybe something that I disabled or enabled needs to be turned on to display the correct numbers I saw before. Again, wasn't that big of a deal, just thought I'd make a post and see if anyone else had similar issues and what their thoughts were.

In short the task manager readings are fine and the thing with the DPC latency increase seems like a very specific thing someone with way more knowledge could take a look. Even then a BIOS update usually makes as much of a difference (usually negative) to increase latency by that much. Maybe save your settings, do a CMOS reset, possibly a Windows wipe and compare.
