Re: Ryzen 9 5950x running very hot 74C

@MisterE 

 

That voltage does seem a bit high for default settings.  If you run OCCT small data set/extreme/continuous, what is your voltage/temps per OCCT at default PPT/TDC/EDC?

Re: Ryzen 9 5950x running very hot 74C

Ok so previous values were -12 on the best core per CCD -20 on the next best and -30 on all other cores.

Now I have -5 on Cores 1 and 7 on CCD0 / -10 on Cores 2 to 6 and 8 on CCD0 / -20 on all cores on CCD1 (9 to 16)
and the scaler on 1x as you suggested.

Still unfortunately seems roughly the same as the previous numbers.

all core:

Single core (somewhat better temps but still no 4.9GHz):

I've spotted something else odd.....
If the EDC is peak current and TDC is sustained current how is the EDC at 100% and TDC at 93-94% given the lower limit of 140 on TDC?

Re: Ryzen 9 5950x running very hot 74C

Damned! I was playing fine, never going over 85°C, totally stock and all of a suddencrash and reboot...

Error 19 Bus/Interconnect Error and 18 WHEA: Cache Hierarchy Error

Any idea on what can cause that?

Why did I move to AMD, why?????

@Fastmikefree 

Maybe this has to do also with the RAM instead of CPU? What settings did you use at last? Are you going to use specific settings for curve optimizer?

Hello

No change on that side, still running RAM at 3800 (in place of 4400) 18 18 18 45 - 1.4V with FCLK at 1900. Did not touch curve as yet since after few hours in use, all cores in CCD1 reach 5025MHz vs 4825 for CCD2.

Note that when gaming (BF5) , freq stay at 4600MHz for all cores with temp now always lower than 80° (only very brief jump to 85°C when in menus between levels...)

@Fastmikefree 

I think you need to find a stable settings for your RAM with a FCLK 1800. Maybe this happening cause of the FCLK. Maybe you can try 4000MHz Ryzen DRAM Calculator but with FCLK 1800. Cause the cache error you mentioned makes me think about that.

@Ero_Sennin 

Might be a good idea! Let me try! This one is a little bit tricky since not easy to reproduce... Thanks!

Re: Ryzen 9 5950x running very hot 74C

My suggestion is you guys just start using CTR 2.0/2.1 and let it do its magic.

It really worked wonders for me. My idle temps went down to high 20 /low 30 from 50+.

Ingame my temps are between 50 to 65 depending on game.

And if u think it will circumcise ur performence just try it. The only thing u have to invest is a little time.

I really recomment it.

You can try the timings I posted at 3600/1800 1.35V.  Honestly 3600/1800 CL16 will give similar performance to 3800/1900 CL18 and be easier on the controller.

Re: Ryzen 9 5950x running very hot 74C

Thanks! That will be my next try if it crashes again. So far, since I change the PSU idle setting to typical, no more problem, but might be to recent to jump to a conclusion...
