[Power / Current Limit Throttling - what to try?]

Thank  you for the feedback - very helpful.  Seems like the more I get into this, the more questions I have...

I played around with the PL1/PL2 limits (Turbo boost power max / Turbo boost short power max in XTU).

Even if I drop them both to 85w, I still get Power Limit Throttling (although my temps drop WAY down - as does the performance....)

I set them both to 270w for now as it seems a reasonable compromise between performance loss and high temps - was kind of targeting 90-95c under sustained load as, if I understand it correctly the processor temp throttles at 100c but is supposed to be comfortable running below that.  Please let me know if these temps are too high still - and what I should be targeting if my assumptions are off...

Screenshot below, I am running folding@home on the max settings as it's about the worse case scenario for processing I can think of.  It pegs the CPU & GPU at or very close to 100%, so generating the most thermals and power draw... 

What I notice is that although I set PL1 and PL2 to 270w, the actual package draw is slightly higher.  I am guessing that's why the power limit is kicking in... 

Is there some other setting I should work with to prevent this?

As for undervolting, I have run into something of an issue where the BIOS has a setting for "Undervolt Protection" which is enabled by default.  This setting prevents me from using a negative offset in the software (XTU, ThrottleStop, etc).  Voltage values in the BIOS currently are set to Auto.  I have tried using a negative offset down to the max the BIOS will allow (-100mv), but have not seen any change in the power limit throttling behavior, so I reverted back to the Auto settings...  I also did not see any change in the voltage values while running cinebench etc in HWMonitor, which makes me think that my changes to the offset are being ignored...

 

 Please let me know what I might want to try for next steps & thanks again!

Yeah, I had been playing around with some of the power profiles in the BIOS to try to address the throttling.

Here's a screen shot after I reverted the power profile back while running Cinebench:

is this still too high? 

Any thoughts on the throttling issue?

Thank you!

[Power / Current Limit Throttling - what to try?]

I'm new to overclocking.  Have been using HWMonitor and XTU2 to try and get my new rig set up.

My overclocking goals are:

1. Don't let the smoke out
2. Get something close to maximized, stable performance that won't adversely impact the life of my gear.

When I started, I was getting a LOT of thermal throttling.  I think I have that pretty well under control now, no temp throttling, cores sit at about 98c when at 100% utilization for extended periods.

What I am seeing is Power Limit Throttling and Current/EDP Limit throttling while running benchmarks.

(Cinebench R23 33503 / XTU2 11065)

If I understand it right, the CPU would like more volts, is the correct?

Regardless if I am right or wrong on the voltage - What can I do to try and resolve this?

Guessing I need to do something in the bios but have no idea what...

TIA for any assistance!
