Video Transcoding on Z790-H

[vortex1]

Just transcoded a video (appended subtitles) and was surprised by how my i7 14700K ran at up to 100°C at times, and the m/board Q-LED red CPU light came on for a period. Quite worrying. I just ignored it tho and completed the task. Not sure I'll be doing much more of that however.

Just saw this review that notes it can overheat! 😬 :

4.0 Excellent

Bottom Line

The Core i7-14700K is the best value of Intel's refreshed "Raptor Lake" CPUs, bringing marked improvements at no extra cost. It's an attractive upgrade for older LGA 1700 systems.

Pros Excellent performance Four more E-cores than predecessor Increased cache No price increase Cons Power hungry Overheats with 240mm water cooler

nb. I have a 360mm water cooler btw.

Hello @vortex1 

The CPU will operate within the bounds of the cooling solution. Watch this video for more information on expected behaviour. 

You can disable MCE to maintain within Intel's designated package draw limits.

With PL1/PL2 unlocked CinebenchR20 pulls around 335w on my 14900KF. (DRAM @ 8600MT).
It's also easy to set Long and Short Power Duration to a current draw that's more suitable for your cooling solution [Internal CPU Power Management menu].

Thanks for the reply @Silent_Scone. I have decided to set the PL1 & PL2 to 253W, and I have turned MCE off.
I looked at the possibility of undervolting, but complete novice. I think it fluctuates (according to CPUID ROG CPU-Z) to around 1.3V which I read somewhere was fine.
If i'm not wrong, I think if I were to undervolt at all with Throttlestop, then what you do is having installed Throttlestop and made the changes (which goes into the program's .ini file) - then you have to keep Throtlestop running in the sys tray at the time for those undervolting changes to stay effective(?) I would like to know in what menu in the Asus BIOS you could make those changes permanent, and then get rid of Throttlestop.
But like I said, I don't think I need to undervolt.
I also wondered if you do undervolt and you say, undervolt too far so the system becomes unstable - how do you then recover from that to then slighlty increase the voltage to say, the optimum working level? ie. would the system still be usable when unstable or would it totally stop working?

I need to stress the CPU again by again running a transcode of a film adding subtitles like before, and seeing if the CPU overheats again and sets off the m/board's red Q-LED warning light again.

EDIT: "..then you have to keep Throttlestop running in the sys tray *all the time for those undervolting changes to stay effective(?)"

I must say, that when I ran' Bench CPU' in CPU-Z, HWiNFO64 reported the CPU as having reached 98°C max during that process. It takes the m/board Q-LED to go off when the CPU hits 100°C

@Silent_Scone Came across this in regards to lowering the temps:

• MCE Off

• SVID Behavior -> Trained

• Digi+ -> Load Line Calibration = 4

• Internal CPU Power Management -> Power Level 1 = 253

• Internal CPU Power Management -> Power Level 2 = 253

• Internal CPU Power Management -> IA CEP = Disabled

• Thermal Velocity Boost -> +2 Profile

As stated, I've made those Power Level changes and turned off MCE - Wondering if I need to make any other changes? (I am a novice to this btw). I saw someone commented somewhere to ignore the 'TVB' setting..
