Question Threadripper freezes when rendering using 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!

1066 is 2133 real speed, the lowest. I think you are overclocking the ram./

 

[DrMrLordX]

I really don't want to run the CPU at stock speeds. .

That's not really the point. The point is to isolate the problem so that you can fix it. If you run your 64GB configuration @ DDR4-3200 without overclocking the CPU, you can eliminate the CPU as a possible source of instability.

Also, it would help if you included some CPU-z screenshots of the RAM tab to show us your speeds and timings while you run the tests.

So I loaded optimized defaults and the ONLY thing I did was set the D.O.C.P profile. I passed a 15 minute AIDA64 Extreme stress test and y-cruncher is good through 5,000,000,000.

Now I'm more confused than before lol What does this mean?

I don't understand your BIOS. Please try and set the ram to 3200, load windows, and run CPU-Z from there. On the memory tab it should say 1600 where mine says 1066. Your memory needs to be running at 1.35 volts. Not if the memory is good, you should at least get 2933 memory speed for that kit you have. That would be 1466 in cpu-z. Since you CPU passed at stock, that is NOT your problem. Below is my memory, but this box is a Xeon. Maybe I will post one of my Threadriper boxes

And your threadripper 3200 memory should look like this if its samsumg b-die This is from my 2970wx with 3200 b-die:

Maybe? lol I just got a BSOD as I was reading this so I pretty much done messing around. Here is a screenshot of my RAM at 3200 MHz.

OK< try 2933, but make sure the bios is giving the memory 1.35 minimum volts. Some motherboards will default everything to 1.2.

I feel like I already went through this. To me this is just going to be a balancing act of the highest CPU OC with the fastest speed I can get the RAM to run at and I don't enjoy that process. I am failing AIDA64 Extreme at 3.6 GHz with the RAM at 3200 MHz. I would rather have higher clock speeds than higher memory speeds, so to me this is all a huge waste of time since I know it's stable at 3.9 GHz and 1866 MHz. At this point I might just get rid of 32 gbs of RAM and go back to 4.0 GHz and 3200 MHz because that was also rock solid.

But what is the memory voltage ? we have already had one threadripper with memory problems, and it was not running at 1.35 volts ! If nothing else, to satisfy me, please make sure your memory voltage is at 1.35 , and reply back with results @ 2933.

I posted screenshots of my CPU-Z Memory and SPD tabs. In the SPD screenshot it shows 1.2v for the "JEDEC" columns and 1.35v for the XMP. I used the D.O.C.P. profile and it set the voltages to 1.35. You may have to be more specific if I'm missing something.

As of right now I got it stable at 3.9 GHz with the RAM at 2933 MHz. Tried pushing it to 4.0 GHz and it froze on CINEBENCH which has not been happening, so I dropped the RAM down to 2133 MHz and it passed CINEBENCH but failed AIDA64 Extreme.

I think 3.9 GHz and 2933 MHz will be what I leave it at and see how long I go without running into any problems.

Perfect ! I know the 1.35 memory is sometimes a problem, and you have to override bios. You did that ? Anyway, for 64 gig of ram, 3.9 ghz@2933 memory is a good result, and what I expect for a stable system.

Edit: On my 2990wx I had 64 gig in it for a while, and had to downclock it to 2933. When I went back to 32 gig (of 3600 b-die) I was able to get up to 3066. But the wx series of threadrippers is a little different. With only 32 gig, I have several 1950x's stable@3566 memory.

And BTW, on threadripper, memory speed is almost as important as CPU speed.

I know from everything I've read, Ryzen's Zen architecture really benefits from fast memory.

Update: I am getting a CINEBENCH score of 3200, passed a 30 minute stability test in AIDA64 Extreme and good through 2,500,000,000 in y-cruncher, but my computer froze when I tried to run the 5,000,000,000.

I guess the real test is to see how it does during the week with rendering in Adobe Media Encoder.

 

[Markfw]

Wrell, I think the settings on memory speed, and memory voltage were your problems, and it appears to be fixed. Zen2 is better at this, and Zen3 (3000 series) is supposed to be better yet.

 

[DrMrLordX]

Now increase CPU clocks until you get instability in 5G y-cruncher. Sometimes running your RAM at high speed can limit your overclock (and vice versa). It's more common on Intel platforms, but it does happen. That's just old-school "isolate and consolidate" testing for you.

By 5G do you mean Calculating Pi to 5,000,000,000 or is there another test I should be running?

Right now I'm AIDA64 Extreme stable at 3.9 GHz and 2933 MHz. Also getting a CINEBENCH score of 3200, which I am happy with so I'm going to leave it and see how it renders with Adobe Media Encoder.

Yeah. Aside from the overclocking issues, which we hopefully fixed, I'm very happy with my 1950x. I plan to upgrade to the 2990wx, if it comes down in price when Zen3 gets announced. Might just skip 2 and go straight to 3 if it's worth it.

Yes I mean 5,000,000,000 ( = 5 gig, or 5G)

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

 

[DrMrLordX]

Good on you. 3.9 GHz isn't bad at all. AMD will have some new Threadripper products later this year if that 1950x isn't fast enough for you.

Congratulations!

Out of curiosity: was it worth it to change to TR platform? I's expecting the encoding time to have gone down because of the many cores but, did it go down enough?
