3950X - Temp & Performance

[Ecridium]

Hi,

 

What is normal temp for 3950X - with Kraken X62 when idle and under load?

 

Mine is about 60 degree Celcius - I use preapplied thermalpaste for my Kraken X62, the configuration is 4 fan 140mm push pull for the radiator, another 140 mm enter the system, another 140 mm for exhaust at the rear, another 3x 120mm exhaust at the top.  I use the glass panel on the Cooler Master H500M case so I expect temperature will raise around 2-3 degrees.  Should I reapply the thermal paste?  All the fans are controlled by the TT controller.

 

Under load (handbrake conversion H264 to H265 and into 720p) my CPU utilization is around 50% is this normal?  The temperature under such load is around 78 degrees, is this normal?  I turned the PBO on, but not even one of the core reach the advertised 4.7 GHz.  Except for PBO and XMP, I didn't touch any other settings on the BIOS.  I also set the power settings on windows to "AMD Ryzen High Performance"

 

Thank you.

we max out at an average of roughly 70 Degrees C, this is based on Kraken X62 cooling.

 

three wPrime 1024M runs

 

 

so small ffts will probably hit in the 90s

What is your idle temp ?  I was really wondering whether I should reapply thermal paste or is it OK to use pre-applied thermal paste.

idle temps dont matter coz they fluctuate to much, i never use pre applied thermal paste i use arctic silver 5 always

[Ecridium]

So... I reapplied the thermalpaste with Grizzly Kryonaut.

I ran some transcoding from x264 to x265 using Handbrake and it ran for 1 day 13 hour or so...

With CPU Utilization ranging in 50%ish, the CPU Temp is 82 C, it peaked on 93 C.  All of the fans are all maxed out.  I even change the front glass panel into mesh.
The question : is this normal?  Or is it hotter than how it is supposed to be?

 

I was wondering if CPU Utilization is on 50% ish and its already that hot, what if it run 100%.  Will the PC be toast?  Or thermal throttling will just happen?  Before I change the thermalpaste I already see the PC restarted on its own twice, I think this is because the thermal exceeded the barrier.

 

I think I already see thermal throttling happens here.  When I start the process, room is still with AC back then, I got 4.2 Ghz on all core, now on 82 degrees it is mostly 4 Ghz on all cores.  All of this is just using PBO on motherboard not through Ryzen Master and certainly not manual overclocking. I also updated the Aorus Master BIOS to latest ~ F11 and reset the CMOS.

 

For another info:

I live in Jakarta, Indonesia.  The room in which my PC is located might not have a good airflow (closed room with no AC on).  I haven't been in the room since I started that process, so I don't really know how hot it is.  After the reapplication of thermalpaste the idle temp is around 48 - 50 C.

 

If by chance I change the X62 with a custom watercooling (Hydro X) and using two rads (360mm and 280mm) what is the probability for one of the core to reach 4.7 Ghz ? I think I will water cool the CPU and the GPU both.  Will the temp improve ?  Since custom water cooling is very expensive I'm considering the practical benefit first (The PC looking cool is just a bonus).

i forgot where i read this but generally unless you are using a loop the voltage has to be under 1.25v, ur currently running closer to 1.3v 4.3 all core. I plan to run my 3950x around 4.1 (4.2 if lucky) when they are actually in stock.

I didn't mess with the voltage.  It was on auto with PBO turned on from the motherboard, not Ryzen Master.  After I updated the BIOS on Aorus Master to F11, at the beginning of the handbrake process it was automatically 4.2 on all cores.  Gradually through time it was around 4 GHz to 4.1 Ghz on all cores.

try a -.05v offset (this was basically mandatory for the 3900x), it's worked wonders for other zen 2 cpus, the problem is that stock voltage itself is often too high, and with 16 cores, getting rid of a bit of excess voltage that you won't need keeps it cool and cuts down the power bill tremendously.

 

If you are lucky, a -.1v offset can be applied and it'll barely hit performance.

Should I be doing this through the Ryzen Master ?  Its like manually setting up the voltage on the motherboard right?  I will try your suggestion though.  Thank you for your reply.

I apologize for the stupid question, it is my first time messing with an unlocked processor and overclocking friendly motherboard.  Never touch the settings in my life before this.

 

I wasn't actually intending to overclock the processor to do wonder, I was actually hoping to know the normal operating temp on these things.  I also wishes to somehow see the advertised 4.7 Ghz on one of the cores.

So its like setting the Vcore voltage to around 1.250 Volt right ?

not exactly, because that'd probably limit your single core boost, setting a offset of -.05v ensures ur just using less power for the needed clocks, The 3950x stock is in the neighborhood of 4.2 all core 1.3v 165w, while the single core boost could be something like 1.4v 4.6, a -.05v offset could mean 1.25v for all cores and 1.35v for single core, and it solved most of the overheating issues in the 3900x as AMD left some headroom so the cpus doesn't blue screen out of the box.

 

If the power draw is anything like my 9900k, a .05v offset at is like makes it draw 20w~ less power, i'd still watch temps on hot days.

I got it.  Googled about Voltage Offset and found https://www.youtube.com/watch?v=97Bd66dfkXs

Thank you so much for your input.  Will try this ASAP with -0.05 offset.

Just to be clear since the motherboard settings is kind of confusing for me.  I'm supposed to type -0.05 Volt on Dynamic Vcore (DVID) but leave Dynamic VCORE SOC (DVID) to auto right?

soc is the memory controller, for your cpu vcore, see if there's a manual and offset mode, use the offset mode and make it -0.05v

 

on another note, your ram is running at 2133, might wanna enable XMP, but one thing at a time.

[Otto_iii]

dono, but 3950x was binned so much better then 3900x it often had same or better temps

Simple fix may be installing the bios you have, or one newer then what it is, from the factory there occasionally are weird/bad configurations, and yeah we could fix it by going through all the settings (boooring), but just reinstalling whatever the version it is will do that, and its quicker, and we all have more time to think about how the new Taco Bell Double Stacked Tacos are selling for only $1 when their normal tacos go for 1.59$, wow what a deal.

Oh so the SOC is when I want to specify the memory settings manually?  So for now it's best to specify it as auto.  I will only set -0.05V on Dynamic core without the SOC.

 

Regarding XMP I already set the Profile 1, so it's running at 1800 Mhz (I'm using TridentZ Neo 3600C16D).  The picture above is from the Aorus Master manual book, since I'm confused which offset should I use.

 

I will update you with the new temps and performance later on, since I'm not in front of the PC right now.

My mobo settings is actually just what you mentioned.  I updated the BIOS to latest firmware and reset the CMOS.  Then I just turn on PBO on the motherboard and leave the other settings on default.

 

I will try xg32 suggestion on using offset though  

[Otto_iii]

This may go into personal opinion, but i consider PBO(+Auto OC) far, far, very far, inferior to manual OC, it always, almost always atleast, runs way hotter, without any benefit vs manual OC

If you want a OC do as Anthony suggested in LTT video from awhile ago, use Ryzen Master and find Per-CCD overclocks for each bank of the CPU, i'd recommend 1.325V because its safe but will work easily, likewise if you can repeatedly run Cinebench R20 with any OC, it will likely, in my experience, work longterm in more demanding stress tests, so its easy to find mhz that works.  After you find OC in Ryzen Master, feel free to apply it in BIOS

At the very least look into negative voltage offset(with PBO) if its a option with your mobo/bios, so far as OC is concerned.  But honestly PBO is dumb and for silly ppl who vape too hard

Thanks for your suggestion. I'll look into it.

So what you are meaning, if I want to go the PBO way I should look into the negative voltage offset.
If I go the Anthony Video way, no need to do negative offset?

Yes so far as that exact question.  So far as negative offset, i wish i could give more info but am on complete budget system, so i can't give proper experience with using it, could be good idea though

old but maybe helpful video

Regardless i'd suggest 1.25-1.325v OC, its very unlikely you will find better sustained clockspeeds then this, the "boost" frequencies you can get with PBO only happen in very single threaded applications like opening a browser tab, for very short limited period of time (no heat on processor), not anything gaming or app related.  Stuff that doesn't really matter, modern and future games care about all-core workloads, and thats why i recommend all-core OCs

To reduce temp under all core load just reduce ppt to 130w or less, whatever gives you the temps you desire.

Just want to report that with current CPU Offset -0.5V the temperature is table at around 47 C no load and under load its around 68-70C.  So yeah your suggestion really helped.  Currently all of its core is running at around 4.2Ghz.  This is with the room using AC when no AC is on it will go around 58C no load and around 78C under load.  The temperature is still acceptable.

 

CPU Offset of -1V make the CPU to only run at 3.9-4 GHz with no temperature benefit, so -0.5V is the way I go now.

 

I still want to try Otto_iii's suggestion though but haven't got the time to fully learn to understand ryzen Master and its manual overclocking capabilities.

 

Previously on my report of 82C under load is basicly my fault.  I ran 2 PC near each other and the second PC is generating heat so bad.   The air in the room itself is not well circulated with no AC on.  Once I opened the room, the temp went from 82C to 76C almost instantly.  I think the rads are just saturated with hot ambient temperature.

 

Thank you for all of your suggestion.  Cheers and Happy New Year
