Threadripper freezes during renders with Adobe Media Encoder

[JediRyan]

So I built a 1950x TR with the intention of it being able to handle pretty much anything I throw at it editing wise. I was having the same freezing issues a while back and someone on another forum said that I was having these issues due to my cpu being undervolted. So I upped it from 1.350v to 1.375v, which made no difference, so I pushed it to 1.40v and everything seemed to work fine. I recently have been taking on heavier work loads doing batch renders now and the freezing issues have started happening again. I know the easiest solution would be to just undo my OC, but I feel like I would be losing out on quite a bit of performance if I drop my cpu from 4.0 ghz down to stock 3.4 ghz. I also like to game on my PC from time to time and there is a noticeable difference at stock speeds. I use an EK Performance 360 water cooling loop so I have adequate cooling, temps never go above 60c even under full load so I don't think heat is the issue. I am wondering if pushing the voltage to 1.425v is safe or should I be going at this a different way? I can also provide screenshots if needed, don't hesitate to ask! I would greatly appreciate any suggestions that I can test. Thank you for taking the time to read this!

What memory (exact kit part number) do you have..and have you tested that with say HCI memtest/KarhuRAMTest

If it is your OC 1.425 is AMDs recommended max, though it's always best to stay away from that for long periods. HAve you simply tried x39 multi at same voltage?

Stock all core boost is 3.7 not 3.4.

This is the part number for my RAM kit: F4-3200C14Q-32GTZR I can't get the exact one as the box is packed away in my closet, but I can assure you I have the correct kit of RAM. I have also tested them with memtest because when I recently upgraded from 32gbs to 64gbs I had to turn the speed down from 3200 to 2933 to get them to work. Thanks to a reply from a forum post on here that I made when I was having BSOD after adding more RAM.

Not sure what you mean by the "X39 multi at the same voltage"?

I know stock boosts to 3.7 but I see a significant drop in fps without the OC when gaming.

If you are running two kits of the "same" RAM...I suspect that is still your problem...especially for 64GB total...

Maybe setting them up manually and tweaking SOC and DRAM voltage would be the best bet.

Is media encoder using your gpu via opencl/CUDA? How high is your ram voltage and your SoC voltage? I had issues with stability on mine running my memory at xmp speeds without increasing the ram voltage to 1.4V and SoC voltage to 1.125V. I also needed to set ProcODT (processor on die termination) to 60 ohms too.

You could try dropping your overclock by 0.25 on the multiplier to see where it stabilises. My 1920x needs 1.325V to maintain 3.975GHz. To get 4.1GHz stable enough to run cinebench R20 required 1.465V and I seriously doubt that it really was stable enough to do much.

I have tried this but I don't know what to do other than manually enter the timings and voltage. I suspect it is my RAM, but not the RAM itself because I have tested them with memtest86.

I really don't want to lower my CPU OC. Media Encoder is using CUDA to render. I entered the RAM timings and voltage manually, but other than that I don't know what to change. I have had no luck with D.O.C.P

Best bet for stability for Zen based architectures is to update the BIOS. So try that first, I'd link you to the correct one myself but I don't know your motherboard.

BIOS updates are critical for Zen.

no offense, but I'm not a complete neophyte lol that was the first thing I did

Memtest86 is not a good test of RAM these days

HCI memtest (run covering 90% of spare memory and one instance per thread) or Karhu RAMTest are much better on these modern platforms

What is SOC voltage set at?

 

[JediRyan]

Soc Voltage is set to 1.2 volts.

I ended up dropping the CPU to 3.9ghz and the RAM to 1866mhz and now I'm stable in all stress tests. I was also able to successfully render 9 videos today without issue, so I guess now I just have to decide if the extra RAM is worth the sacrifice in memory speed. I may end up taking 32gbs out, putting the CPU back to 4.0ghz and the RAM back to 3200mhz, since it was stable and compare render times. I also want to compare the gaming performance of the two configurations and see what the results are.

I attribute my success thanks to the discovery of this chart: https://www.overclock.net/forum/attachment.php?attachmentid=85289&d=1518612831

2 weeks in a row without any problems! *knocks on wood*

I'm happy to report that I have been able to successfully render over 20 videos without any issues!

I ended up dropping my OC to 3.9 GHz and got the RAM running at 2933 MHz.

I'm AIDA64 Extreme stable and getting a CINEBENCH score of 3200, which I am very satisfied with. CINEBENCH Extreme score of 870 for those interested.

Thank you to everyone for their input to help me figure this out

Cool beans!
