Threadripper 1950X Clockspeed

Hello,

I am new around here and also new at AMD processors. Actually I changed everything in my setup moving from Apple iMac (15 years apple user) and get back to build a new PC from the scratch. A few months of research and investigation made me comfortable about which hardware to choose and also with the actual PC world, because everything is so different in the good way.

My Build:

AMD Ryzen Threadripper 1950x

Cooler Master Masterliquid ML360 TR4

ASUS ROG Strix x399 E-Gaming

Hyper X Predator DD4 3000Mhz CL15 - 64GB (4x16GB)

ASUS ROG Strix RTX 2080 TI 11GB 

Samsung 970 EVO PLUS - 1TB

Western Digital Balck 2TB

Corsair HX1200 80Plus Platinum Modular - 1200W

NZXT H700

I work as Product Designer and I use the Cinema 4D for 3D modelling and rendering. Now and with this new build I am ready to start playing around with GPU rendering, but for now I only need CPU rendering. So I used to buy i7's with turboboost and hyperthreading what is extremely useful for my 3D renderings. However with my 1950x that is 3.4 - 4.0Ghz I only get 3.7Ghz "stuck" (after installed driver). For example, with my last i7 Skylake that was 4.0 - 4.2Ghz it managed his clock speed for his own need, if I was rendering it will boost to 4.2Ghz and when it finished it will "drop" the clock speed to 4.0ghz (or less I am no sure). I thought the Threadrippers will work in the same way managing the clock speed according to his need, but now I am not sure about that. Before the driver installation the clock speed was constantly moving up and down from 2.2Ghz to 3.7Ghz, with nothing running in background. Concluding what I need to know is if there are a possibility to make it work 3.4 to 4.0Ghz automatically. 

By the way I tried to use Ryzen Master and everything was alright until I tried to "force" him to work at 4.0Ghz to run a Cinebench but the RM just crashed my PC. I rebooted and when I opened the RM again it automatically crashed my entire PC. I uninstalled and installed it without made any change and it crashed my PC again. So the RM is not a solution for me.

I tried to find a topic about this subject but I didn't found it, I hope that I didn't missed it.

Sorry if this is a long post but I thought that was important to you understand my needs and everything else.

Thank you for your attention,

João Mendes.

Re: Threadripper 1950X Clockspeed

jppm, please post a screenshot of Ryzen Master (RM) - simply drag-n-drop the image to your reply.  Please tell us what Power Plan you are using.  I know nothing about Intel processors but suspect AMD's work very similar.  The processor manages the clocks and voltages to do the job but with constraints.  RM will help us see if you are bumping into one or more of these constraints.  I am running a 1950X right now, so if you can refer me to a bench to run, I can see if I can reproduce your situation.  Thanks and enjoy, John.

Re: Threadripper 1950X Clockspeed

Hello misterj,

Thank you for your replay.

As you asked I will attach a screenshot of RM and Power Plan:

The PP choosed is the preset created by chipset driver and I left it as it is.

I gave another chance and reinstalled RM to took this screenshot, after that I runned a 3D file to render an image and see the clockspeed, 4 times I tried 4 times it crashed. Crashed with Cinema 4D and RM running at the same time and also crashed with Cinema 4D isolated. However I registered the CPU temperatures at the crash moments, so 1st was 58.75º, 2nd 60.25º and 3rd 61.63º (4th was without RM on). So at this time I am not sure what is wrong, because now I realised that some how the system it's not that stable. 

Thank you for you support.

Cheers,

João.

Re: Threadripper 1950X Clockspeed

"First be sure your Asus Motherboard has the latest BIOS version (04/03/2019 - v1002) and Chip Set (01/22/2019) from here: ASUS ROG STRIX X399-E GAMING | ROG - Republic Of Gamers | ASUS USA 

 

Second check to see if your RAM Memory is listed for your Motherboard's QVL List from 01/19/2019. I have it attached to this post to download by clicking on the file.

 

It is normal for the CPU to fluctuate between low to high speeds during normal operations. If you have PBO enabled that should be able to run it at a higher frequency in BIOS. But PBO is considered to be Overclocking and will void your CPU warranty.

 

I would reset BIOS back to "default" either through BIOS itself or through the motherboard by removing CMOS battery. If you update the BIOS, it will automatically be installed as "Default".

 

Also make sure your Ryzen is not overheating which will throttle the CPU into a lower frequency automatically.  The maximum operating temperature is 68C. It will probably start to throttle before reaching this temperature and will definitely throttle after reaching and passing 68C."

Hello elstaci,

Thank you for your replay.

The BIOS has the latest firmware (04/03/2019 - v1002) and my memory set is in the QVL list, it was one of my concern about compatibility (HX430C15PB3K4/64).

About the PBO I can´t find that option on my ASUS BIOS, I saw this Youtube video but in my BIOS there is not such option: https://www.youtube.com/watch?v=JVQIL_nn7OY

"But PBO is considered to be Overclocking and will void your CPU warranty"

I didn´t know about that I thought that was an official AMD software with the goal of run the CPU as it should run!

About temperatures never seen the CPU above 62 - 63º so I thing that is not the problem.

I will think about more test and I will relate everything here.

Thank you for your time.

Cheers,

João.

Re: Threadripper 1950X Clockspeed

Wow, sorry, jppm.  I cannot see your screenshots.  Please try again.  You must have an image file like .jpg.  You can also use the Camera icon at the top of the reply window.   Those temperatures are fine.  The limit on all Threadrippers is 68C.  Please give me a link to Cinema 4D so I can run a free trial if there is one.  If there was something I can duplicate, please tell me how to get it.  Did you change anything except installing RM?  I have never seen RM cause these kinds of problems and it always opens in the Current tab (at bottom, far left) which is read only.  Please preform a Clear CMOS using the manual instructions.  Please let me know what you learn.  Enjoy, John.

Re: Threadripper 1950X Clockspeed

See if you have a BIOS Setting called XFR as per this Asus thread: How to enable XFR mode of Ryzen? 

Okay, seems like PBO is for the Ryzn 2xxx Processors and not the Ryzen 1xxx Processors. So you need to configure XFR/PB in BIOS.

Check under AMD CBS Section in your BIOS.

Ok it seems to be alright now.

You can try Cinebench that will render a file and it´s very known benchmark nowadays.

The difference between both 1950x it's before and after I overclocked the memory to 3000Mhz that is its clock.64gb 3000mhz cinebench.JPG

Re: Threadripper 1950X Clockspeed

jppm, PBO (Precision Boost Overdrive) is for Ryzens 2 and 3 - yours is 1.  Please do not worry about XFR (eXtended Frequency Range) now - it does not need configuring.  The first thing is to get your system stable.  The Clear CMOS should get your system into a condition to run fine.  I really need to see your RM screenshot.  Please make sure you have version 1.5.3.0902.  Here is a screenshot I just took:

Good luck and enjoy, John.

Re: Threadripper 1950X Clockspeed

jppm, I can see them fine now - both RM and Cinebench.  If I can find R20, I will try it.  I do have it and am running it now:

pastedImage_1.jpg

Not bad for two sticks of 16 GB memory (Dual Channel not QUAD).

Your RM looks fine.  For testing, I would let your memory run at SPD speed to see if that helps stability.  Enjoy, John.
