5700X overheating

locrieth · 19 Apr 2022 at 19:05

Thats while I'm running cinebench single core benchmark

locrieth · 19 Apr 2022 at 19:09

Its a Asus "Feature" I haven't changed it, i think ihad a look and most people seemed to imply you should leave it on auto... after a bit of reading looks like some people are saying to turn it off for Zen3 chips

locrieth · 19 Apr 2022 at 19:17

ok mate i'll do that now and post back, enjoy your dinner

Sorry got a little side tracked trying to fix an ancient laptop for my wife's uncle. So ran a single core cinebench with PBO Fmax Enhancer set to disabled and PBO set to Auto and I got 1495 and temps haven't gone above 54.5C, just running multicore now.

Multicore seems a little low, but temps are still low too

Its difficult to know what the score is supposed to be, the 5600X is also a 65 watt CPU but 6 cores, it scores 11,000, the 5800X is 8 core but 105 watts, it scores around 15,500. So somewhere between that.

Your 12.172 run looks perhaps a little low but temps are excellent and its only drawing 62 watts on the cores.

The 14,579 was a higher? over 100 watts on the cores.

@locrieth what are you getting on yours, stock?

That was mine at stock (12,172), I think the other scores must have been when I had PBO enabled and PBO Fmax Enhancer set to auto. I dunno whether to just reset bios to defaults and turn DOCP on and see what i get, don't think I'd changed anything else but just to see what the defaults should be...

So I've disabled (from Auto) the fmax setting and I did 2 tests one with PBO set to Auto, then set to enabled:

CPU PPT MAX: 76W

CPU PPT MAX: 120W

locrieth · 20 Apr 2022 at 00:37

With the PBO enabled doing Prime 95 smallest FFTs still goes up to 90C and 155W CPU PPT. So my options are leave PBO at auto and sacrifice a bit of performance or leave it on as the Prime 95 smallest FFT test is unrealistic in real world scenarios. I basically use my PC for gaming ...

Thanks for all the replies, so I never really messed around with any of the bios settings for my 3600x, i just stuck DOCP on and done. Looking at my last pic the one with PBO enabled (not just auto)

I noticed that the max was:
PPT = 120W
TDC = 79.7A
EDC = 134A

Are these values anything to worry about, do they need to be limited or are they ok as long as my temps stay reasonable? With the TDP of the chip being 65W, do they relate in any way?

I'm not trying to OC the CPU per say, I just want to get the most out of it and let the BIOS make the correct call on the safety side of it (set it and forget it kind of thing)

Sorry if these are sort of noob questions.

I was just having a look at TDP and from what I can tell its not a power draw, but a heat expelled rating according to Linus:

So does this mean that the PTT is the actual power draw and is there a max limit on the amount it can safely draw?

I have the opposite here... 3700X at 95C but 5700X at 80C

What PBO settings are you using in the BIOS?

humbug said:
Yup, the 142 watts is actually the socket power limit.

So does that mean its a hard limit of the socket? i.e the 120W my PPT is pulling is well within the range for the socket?

I read this bit but the "at Least" confused me a little as that implies its a minimum usage

Default for Socket AM4 is at least 142W on motherboards rated for 105W TDP processors.

No its just the default you can go over it.

Wheres this quote from userbenchmark it should read Default for Socket AM4 is at most 142W on motherboards rated for 105W TDP processors.

To be fair i've seen that same quote, when trying to read up about PBO, PPT, EDC and TDC from multiple sources, albeit formatted exactly the same so they may all originate from the same source...

This was the last one i read:

This is the theory

Package Power Tracking (“PPT”): The PPT threshold is the allowed socket power consumption permitted across the voltage rails supplying the socket. Applications with high thread counts, and/or “heavy” threads, can encounter PPT limits that can be alleviated with a raised PPT limit.

Default for Socket AM4 is at least 142W on motherboards rated for 105W TDP processors.
Default for Socket AM4 is at least 88W on motherboards rated for 65W TDP processors.

Thermal Design Current (“TDC”): The maximum current (amps) that can be delivered by a specific motherboard’s voltage regulator configuration in thermally-constrained scenarios.

Default for socket AM4 is at least 95A on motherboards rated for 105W TDP processors.
Default for socket AM4 is at least 60A on motherboards rated for 65W TDP processors.

Electrical Design Current (“EDC”): The maximum current (amps) that can be delivered by a specific motherboard’s voltage regulator configuration in a peak (“spike”) condition for a short period of time.

Default for socket AM4 is 140A on motherboards rated for 105W TDP processors.
Default for socket AM4 is 90A on motherboards rated for 65W TDP processors.

Right so I working from home today, so I can tinker a bit. The values I had max while running CB R23 today were:
PPT = 125W
TDC = 82A
EDC = 138A

In AMD RM the limits are set to:
PPT = 395W
TDC = 160A
EDC = 190A

So, do you think I should take the max settings I got in CB R23 and add about 20% on then set them manually in BIOS?

I.e.:

PPT = 150W
TDC = 100A
EDC = 165A

locrieth · 21 Apr 2022 at 10:01

I stuck those limits on and ran CB R23 for multicore and single core and they stay happily in low 70s. So i ran Prime95 on Smallest again and it did hit 90C but it took a good 6-7 mins to get there now rather than 5-10 seconds before:

TDC hit 100% of limit and PPT was 144W so 96% limit

sorry for such late replys so i actually just did a test now with pbo fully enabled in my bios. and ran prime 95 with smallest ffts
and i also hit around 90c within a minute.
so it is 10000% an issue with pbo..
so i set it back to auto and my highest temps with smallest ffts is around 66c again very weird

Have you got Ryzen Master installed? If so what does it show your PPT, TDC and EDC values at?

Hey All,

Sorry to Bump this necro thread, but I think my EVGA CLC 280 might be on its way out as I'm having loads of USB disconnect and reconnecting happening in windows. I tried reconnecting it to a different USB header and straight to a USB port same thing happens and my temps jumped up to 106c when it was literally idling at 5% CPU. There's a 5 year warranty on the AIO so I'm trying to see about RMA, in the interim as a temporary work around, do you think the Wraith Spire cooler from a 3600X would be sufficient with no overclocks and if I turn off PBO? I'm working on the thinking that the 5700X is a 65W CPU and the 3600X is a 95W CPU...

Any thoughts?
