5800x Temps and PBO Settings?

[lost-signal]

So I've had my 5800x since launch, the cooler is a Dark Rock 4 (non-pro) and as I'm sure most of you here have heard many times before, it runs toasty. Stock settings, Idle is around 40-50c, gaming upwards of 70c and cinebench multicore it very quickly hits 90c.

I adjusted my PBO settings in bio as follows:
PPT: 105
TDC: 75
EDC: 90

Idle temps sway closer to low 40's/high 30's, gaming is honestly around the same but closer to high 60's and cinebench multicore hits mid 70's/low 80's. Are these settings ok to use? Is there anything i should be concerned about? My cinebench r20 scores are 5681 multi and 621 single, are they ok scores for such PBO settings?

Try use those settings in conjunction with a curve optimiser negative offset.

How much of a negative offset should I test with? Also, do the double digits refer to mV?

Each -/+1 in curve optimizer reduces or increases voltage by 3-5mv depending on if it's high or low load so at say an offset of -10 the CPU will use 30-50mv less for the same clocks or if it has power and thermal headroom then it will use the same power as it did oringally but will further boost the clocks.

This is where capping the PPT TDC EDC along with curve optimizer helps when trying to reduce temps as it will mean the CPU will just boost back to or slightly higher then original clocks while using less power and less heat.

I would start with -20 and run some stress tests and if it seems stable then use the system for a while to see if you get any random reboots as a lot of the time the crashes can happen at low loads / idle when surfing the net or watching YouTube etc so it can take a while to find the perfect settings.

So i did try a -20 and noticed certain games freezing/crashing after a certain point, so i have it set to -15 and will test that for a while today
