5800x (and other Zen 3 chips) PBO settings/Temperature fix

[Ibizadr]

I don't understand but my 5800x with artic liquid freezer 240, stays in gaming never passes 60ºc and on r23 multi 72ºc. And I have my PPT, EDC and TDC at +35% from original and +200mhz. PBO2 - 30 all core, except for 3, best core do - 17 second best - 11 and for some reason core 7 only reach - 20 on curve optimizer. Never have issues or crashes

The quieter my system runs the warmer it runs.. I am only guessing, but many people focus on silence rather than high performance.

I think that too since I have my fan rad at full throttle at 60ºc

So what's the problem?

the liquid freezer/II are literally the best AM4 AIO's on the planet

Low threaded is where mine bounces to the moon at stock settings, i can get 60C multi threaded but 80C bursts dragging minesweeper around

Only a PoV why you quoted?

Yeap the burst on this processor bounce temperature radically. Only open hwinfo and its spikes from idle 3xºc to 4xºc in a second, but after it returns to its normal. This is aio its absolutely nuts, the only mistake I made was buy 240 when 280 its the correct one for me. I buy it to put it on top and then my rams and my case don't let me put it on top so on front 280 was a better deal.

I'd see spikes of 80-85C, while load was at 60C


Half the issue is the motherboards IMO, certain brands do dumb shit to boost performance that you cant disable

I run my 5800X at Eco 65w which is an 87w PPT. This translates to an all-core clock of around 4.2 GHz and about 60C temp.

Without Eco 65w, it would run with an 141w PPT, 4.6 GHz. and 95C temp (with fan screaming bloody murder all of the time).

This is BOINC 100% load. 400 MHz isn't worth nearly doubling the power draw, in my view.

Is anybody getting this kind of boosting on there 5600x? This blows away my 3600 to say the least. It'll stay all core like this for 10-12 seconds.

Yep. And it gets better with a bit of Curve Optimisation...

 

[ntdouglas]

Never messed with that. Care to elaborate?

Semi-automated undervolting, less volts means less heat - so higher boost

Do it too far and it's unstable at idle, usually

 

[thesmokingman]

Yeah, it is indeed the hottest Zen 3 part and that's no surprise given the die layout.

No, look at the TDP divided by the number of cores. The 5800 has more power available to each core vs any other part in its lineup.

Both views are correct
By Die layout, they mean 8 cores in a single CCX - and then it has the high wattage on top.

The newest AGESA might be working on that with the 1.45V VID cap

I don't think so as far as die layout. The 5800 is no different than low core count dies which then get the full TDP classification cpus in other segments like the 3960x which is a 24 core TR which gets a lot more power per core. The fact is each core is getting more power, running at a much higher state. Just guessing that its cuz there's 8 cores in a die is just guessing. You guys do realize that AMD have other chips with 8 core per die as a normal starting base right? And then with the TR Pro lineup they released even more low core count TR with higher TDP. Compare the 5900x vs the 3945x, note the staggering difference in TDP class.

That's not all-core, that's just another application that isn't programmed to read Effective/average/snapshot frequency. If it was actually 4850MHz all-core load you wouldn't be looking at 45C even with your AIO. Run HWInfo on another monitor if you have one, and you can see what the cores are actually doing.

Cores-wise Ryzen 5000 doesn't behave differently at a fundamental level. It just clocks higher with less Vcore and has a bigger CCX to work with.

I've gotten up 4,915mhz on my 5600x with a slight Bus speed bump. You have a golden sample like mine in CTR
Might does that too usually I read HWinfo for the real.

Me thinks that disabling PBO at stock settings and settings the power limit at 105W could be the best combo for performance/temps/acoustics.

 

[Hoper]

none of this oc matters. there is only 2 options to consider.
1. thermal ceiling limit
2. the 200 mhz overboost.

Now that we got that out of the way. We are all stuck with a glaring problem.... Cooling.
If you want better cooling. get a delta fan @ 10,000 rpm.
AIO and Open loops are just too weak to cool any further.
We need an entire new thinking on how to cool these processors and no one has come up with a viable solution.

In bios under advanced you can select curve optimizer and set a undervolt offset pr core. What this does is running the selected core at a lower voltage. Only risk is unstability, but it cannot destroy components.

On my 5600X I currently run C1: -27, C2: -29 and rest on -30 and PBO + 200. In cinebench this ups my boost at 76W PPT from 4.3GHz- avg to 4.6GHz avg at same temp\consumption which boost score by 6%. In SOTTR I got about 5% more fps using this setting vs stock with no CO+PBO. If you wanna try it use core cycler to find the rough scheme, then adjust cores individually after checking event viewer if you get reboots later. Corecycler gets it 99% stable. I had to lower core 1 by 2 more and core 2 by 1 after a few months.

I run my 5800X at Eco 65w which is an 87w PPT. This translates to an all-core clock of around 4.2 GHz and about 60C temp.

This is BOINC 100% load. 400 MHz isn't worth nearly doubling the power draw, in my view.

Try curve optimizer and +200 pbo, you can still run 65W, but you will get +200 single core and about 2-300MHz more allcore if you are lucky with binning, a PPT of around 100W would probably get you to around 80C max and using CO you will probably get allcore of 4.6 then

Keep us in the loop I have the same mobo and was looking at it the only thing that was putting me off flashing it was it's Beta designation otherwise I would have been on it like white on rice

A Delta fan at 10,000 rpm wouldn't make any difference. There's a limit to the heat that can be transferred away from the cpu. The problem is that you have one tiny chip on the corner of the 5800x that produces all the heat. You can't improve that without de-lidding it and since it's soldered on and would break the chip to take the lid off, there's nothing you can do about that. So the viable solution is what this thread is all about: use a great cooler with good contact and thermal paste and limit the power in such a way that it doesn't reduce performance.

the 95-115 range is where i found its sweet spot

The heat issue isnt about the cooler, its about the IHS.
It's like when intel went away from soldering, except users cant fix this one.

AMD needs a re-design, the 3D cache may help work as a heatsink/better IHS contact
