![]() Seeing a <100% PRD just means that the CPU is operating outside its rated PPT that AMD has set for product segmentation purposes. ![]() BECAUSE you keep it on auto/stock setting the internal regulator of the CPU (the silicon FITness controller) is still on and protects the chip by regulating voltage/frequency/current and eventually temp. When the CPU is on auto/stock settings and you see a PRD under 100% when you FULL load your CPU you dont have to fear anything. So the true power draw is 88 - 10% = 79.2WĤ. Hence the true/actual power draw (PPT) is the difference between 100 and 110 =(-10%). This means that the 88W you see during that test is the 110% of the true/actual power the CPU draws. You run R20 multi benchmark and you see a 110% PRD and a PPT of 88W during the test. You have a R5 3600 Ryzen rated at 65W TDP with 88W max power draw (PPT). So the true power draw is 86 + 10% = 94.6W ![]() Hence the true/actual power draw (PPT) is the difference between 90.9 and 100 =(+10%). This means that the 86W you see during that test is the 90.9% of the true/actual power the CPU draws. You run R20 multi benchmark and you see a 90.9% PRD and a PPT of 86W during the test. Any other situation is uncountable and/or irrelevant. Power Reporting Deviation ONLY counts when CPU is on full 100% load. _Using any manual setting on voltage/multi disables any regulator (false or true) that the motherboard introduces and it even disables the ultimate protection of the CPU = The FIT controller that cannot be bypassed by any board regulator (false or true), ONLY IF the CPU is on auto/stock settings.Ģ. Boost is on, with or without PBO (Disabled/Auto/Enabled). Power Reporting Deviation ONLY counts when CPU is on stock settings. this thread is overinflated by unessesary questions and more.ġ. This is a thread, one of those that you tired reading again and again the same questions, as if the answers are not on the OP (by The Stilt) and/or Martin's posts, the author of HWiNFO. but tried everything and 1 ) my motherboards regulators ARE OFF 2) ON AUTO CORRECTED DEFAULT AND EVEN WITH LOWER PPT TDC EDC VALUES with precision boost 2 are hot garbage ![]() temps / clocks and power - from wall- with a simple static multi + "static" low voltage + (btw the later not technically true, ryzen master shows that all cores ALSO go to SLEEP, and vcore goes WAY down to NOTHING with a " static" voltage and multi ( 4.2 ghz) i really like to run things stock. i give up? i just have -insanely- better EVERITHING. ![]() im STILL SEEING CRAZY TEMPS SWINGS from 32c to 47 C vs STABLE 100% locked 32c temps with fixed 4.2 oc in games? all cores DID go to 4.2 ghz with the capped pbo settings. lower cpu tempS on auto! with boost on, running cinebench 20, BAD! SHIT lower overall boost not even reaching 4.2 ghz. "playing" with pbo settings, prime B450M-A / r5 -3600 / eventually just copied the PPT-TDC-EDC values from my FIXED all core 4.2 ghz 1.1v oc and put those MANUALLY on bios ( PBO) (60) PPT (36) TDC (80) EDC > ( also did 45- 35- 70) GOOD. Sorry " The FIT controller regulates frequency and voltage within a few msecs in very short but rapid bursts to keep performance high and silicon stress low, that no static frequency or voltage can match." this is 100% BS. Of course I could've gone for a bigger cooler, but I had the Ultima90 lying around since I retired my Core 2 gear from my 2nd rig, and I wanted to make good use of it, also I figured it would be good enough as I won't be overlocking the 3600, and it is. See here for more numbers on power, temps & clock speed effects vs CPU PPT.Īnyway, I have now finally ditched that POS cooler & have fitted my ancient (but still good) Thermalright Ultima90 on it (using the TR True bolt through kit which is available again atm), that has dropped CPU temp's by about 15+C! It also significantly cut power usage with only a modest lost in all core loaded clock speed of 3-4% (I don't know about single core clock boost). I've got a 3600 and I started with the stock Stealth cooler, I found out within minutes of installation that cooler is a worthless pile of junk! Running (full load to all cores) it went into the high 80s & was thermal throttling! I knew looking at the cooler it wouldn't be much cop (it's tiny & is all Alu), but it is actually incapable of cooling the CPU properly! Note this is with stock Bios settings, and the power deviation for that is ~99% (as I posted previously), and no sign of over-volting.Īs a temporary fix I lowered CPU PPT from default 'auto' (max 88w) to 65w, this dropped loaded temps to about the mid 70s. ![]()
