Hi all,
I noticed an interesting thing since a few version updates ago of BOINC, but I don't know if it is a BOINC bug or WU bug or what but, these are the symptoms:

Let's say I have BOINC running 100% CPU time and 100% core utilization for many days. I check in HWInfo64 (and can hear from my fans spinnings loudly) that everything is crunching away. Tdie temps of 73-78 C, CPU power draw is reported as 310-340W. Okay nice :)

Now, let's say I need a reboot of my machine, perhaps Windows update or I installed som driver/software, whatever reason. Back in Windows 10 after reboot I start BOINC and now I can see that while all 64 tasks are still running, the increase in percentage of most tasks is very slow. Mostly this seems to affect OPN WUs, but I am not 100% certain on this.

I hear on my fans that they are not ramping up very high so I go to HWInfo64 again and while CPU usage is 100% on all cores, the temperature (Tdie) is 58-63 C and the reported wattage is 220-230W "only".

Now, here's the really interesting part:
If I leave it crunching this way, then as WUs finish (which takes a long time since they progress slower) and new ones start, I gradually see that the power draw of the CPU increases: 240W->260W->285W->etc up to the usual 320-340W. This process takes many hours. As it progresses, the fans ramp up and temps rise etc until it is back to steady-state at full-steam ahead.

Has anyone else notices this? I currently crunch OPN1, MCM1 and some ARP1.

The system is overclocked and is stable, producing valid results only and no crashes.
