Threadripper BUILDERS thread

Hello Threadripper gurus. I've been lurking around this thread for the past 2 months since I threw together my first Threadripper (and pc in 15 years) build. I use this machine for my freelance 3d modeling and animation work.
Up until now I haven't done much to really beat on it, but I've got an upcoming rendering project and have been beginning to put it through it's paces. Unfortunately I completed the build before I learned of this thread so there may have been some less than perfect component choices made. The AiO I purchased hasn't been able to keep a 4Ghz overclock cool in these warm temperatures with all cores running 100%, so I've returned to stock settings except for RAM which I've got running at 3333Mhz. Anyway, I've been leaving HWiNFO64 open while test rendering to keep an eye on temps, and I've noticed whenever I begin rendering, all the core VIDs drop from ~1.4, steadily down to the 1.05 range. Clock speeds start at 3,699 - 4,024 and then drop down to 3,400s. The test rendering takes maybe 30 seconds, and none of the temps are really spiking, Tdie hasn't even hit 60*, not even enough to trip the next stage of fan speeds. I'm assuming this is some sort of throttling going on, but I'm not really sure what's up. I've got a 750watt power supply in there so it doesn't seem like I should be running out of watts. Any thoughts? Thank you for the insight, and thank you for all the knowledge I've gained just by browsing this thread.

I've got my 1950x aircooled with the Noctua NH-U14S TR4-SP3.

I normally run Distributed Projects with mine at 100% load 24/7.

Anyway, my TR gets around 61~64C. It never pings at 68 like it use to with my old AIO cooler...

That being said...I think it really depends on how the program(s) you are running handles the the CPU load, Not all programs can utilise all the cores. Like BOINC bounces around my clock speeds from 3429~3699 Just fluxuates all the time, even those the CPU reports 62C/63C. I have an APC that I can monitor the watts and even with a 1080ti going full load, I'm pushing just under 500 watts. I have a 850watt prime powering my rig. So, I don't see any reason your power supply shouldn't be able to keep up with your specs.

Probably you best bet is to get a good baseline. I use cinebench before I run it all cores sit at 3699 and when running they all pretty much drop off at 3500. So, I see this as normal. As long as you have a good baseline, it's pretty normal to see the TR fluctuate with whatever app you might be running at the time.

What is your AIO ? not in the specs. BTW, the Only AIO that will work correctly is the Enermax TR4 360 (for an overclocked machine)

 

[8080ff]

Thanks for the replies. I primarily use Cinema4D and VRay, and (at least according to HWiNFO) all threads are running at 100%. I ran Cinebench R15 and saw the same behavior, so I guess that's the way it is? Seems kind of strange to me, but then again I make pictures for a living, not design complex electronics. Thanks for the tip on the Noctua, I've had my AiO (Fractal Design Celsius s36) listed on Craigslist for a while with the plan of picking one of those if I can get rid of what I currently have. Have you ran the Noctua with Threadripper overclocked?

 

[ericlp]

Negative. You'd not want to OC on air. I find the TR pretty effient even at stock levels. So... I am just going to deal with it, unless I get bored and go custom loop.

I use to have an enermax 360 tr4 and I think the pump died. I tried to reseat it a bunch of times and it's just a pain to me to run an AIO. I know there are a lot of people that are happy with their AIO's, I was not one of them. However I'm really happy with the Noctua, as my TR idles at 31C (it never is idle much) and I am pretty happy for 62/63C at full loads. I've only had this for about a month so, long term, I'd like to see how long these temps are stable for. I like the simplicity of air, I think, on a custom loops seeing looking at the reservoirs fill up and water move along the tubes, would be a lot better for me as there is just no way to see what's going on with an AIO, other than monitoring temps.

 

[ericlp]

I should point out, that my office is AC 24/7 at around 71 degrees. Also I have no carpets, just laminate planks. So, try to keep dust at a minimum when I run the sweeper around.

Also... I have a modified ThermalTake view 31 case, that is maxed out for airflow. I have 6 140mm fans 3 intake in the front... With a removed front grill for maximum airflow. So, I think my results might be the best one is to expect from an air cooled rig. I think having the correct case that provides plenty of fresh airflow is key. Like you I also have a asrock taichi, and I mounted my Video Card in the 4'th slot away from the cooler. So... I think (your results will vary) might be in order. I should be upfront on expectations on my setup and what you might get from your cooler.

AIOs and custom loops don't provide airflow over your VRMs. It's possible they may be getting too hot causing throttling (you can check by putting a fan blowing on them to see if there's any improvement).

 

[ericlp]

HWinfo, does monitor Asrock's Taichi VRM's.

ASRock X399 Taichi (IRF IR35201),

Mine are always at 65C. I guess that's normal for good airflow case. I think they were a bit higher when I had the video card in slot 1. I read if they are under 80C your fine as I've seen some people have temps in the 100's. Ouch...

65C isn't a bad temp, but if it's always the same and never changes, I'm not sure how accurate the software is. HWINFO has been pretty good with voltage on the boards I've used, but I haven't used thermocouples to double check reported temperatures.

 

[ericlp]

but if it's always the same and never changes, I'm not sure how accurate the software is

I should say, it never changes when at 100% load, as soon as I snooze the cpu, it drops down to 42 or so degrees.

That sounds better.

 

[8080ff]

I've been running small jobs all evening and the neither of the VR temps has gone above 51.
@ericlp thanks for the additional details. Maybe I'll be looking at a custom loop this fall if the tax gods are smiling on me. Thanks for the input everyone!

 

[kaporkle]

Urvile, that looks fantastic. How is the Heatkiller performing?

 

[B-Riz]

I decided to dip my toes into the Threadripper waters with the 15% off eBay coupon today and grabbed a 1900X and Taichi. Need to figure out cooling; I have a Corsair H110i GT I hope to use. Hoping to grab a 2920X later on.

 

[Markfw]

I am pretty sure the bracket that comes with the 1900x will fit your cooler.

And, lol, of course the AIO I have does not work. https://www.amd.com/en/thermal-solutions-threadripper

https://youtu.be/NWzyKzvezOo?t=1630 This mounting used some aluminum pieces to hold the bracket that comes with the cooler in place, which I think I can do.

 

[Markfw]

Hydro Series™ H100i v2 is supposed to work. And isn;t that what you have ???

Sadly no, it is the H110i GT, which is a square pump.

 

[Markfw]

Well I would still get a full coverage HSF or AIO to cool that sucker. All mine are.

My TR1950x is OC'd just fine @ 3.7Ghz all core w/ 3433 @ CL14.
CPU will hit a max temp of 67*C in prime95. Clocks stay locked @ 3.7.
CPU draws about 250Watts in this scenario.
I did a max system test w/ AIDA64 in which I CPU stress tested and stress tested 2 1070 GPUs dumping hot air into the setup.
Wattage util hit around 500-600Watts. No issues with stability or temps.
I have 3 120mm fans blowing into the chassis unrestricted.
2 140mm blowing out + 1 120mm right above the CPU
Room temp was ~78*F

You absolutely do want to apply a mild OC on air IMO. You'll go from 180W max TDP stock to 250W max TDP.
I've heard horror stories on the enermax 360... Its 100% guaranteed its corroding internally and you're eventually going to get a leak.

A custom loop is safer but the cost/maintenance aren't worth it.
I see no point going water with a much safer/cheaper Noctua doing the job just fine.
Above 3.7Ghz @ 1.2V, you head into some pretty serious power inefficiency for 300-400 more mhz.
If I get max 250W draw from the cpu @ 3.7 / 1.2V, I don't even want to think about what power utilization is occuring @4ghz.

There's no way your temps are correct for 3,699 - 4,024 all core on a non-360 rad.
4Ghz all core is pretty serious business. You're likely @ 300Watts+ on CPU power utilization? You said you took down the OC due to summer temps? So, those clocks seem to be what you get stock..

3.4Ghz base clock

• Incredible 16 Cores and 32 Threads of processing power
• 4.0 GHz Precision Boost (up to 4.2 GHz with XFR)
• 40MB of Cache Memory
• 64 PCIe Gen3 Lanes
• Quad-Channel DDR4.Max Temperature:68°C

180W TDP can be hit w/ a ram OC and base clock of 3.4Ghz.
So, you're getting stock behavior.. a pop up to 3.7-4.0 on a handful of cores which then settles down to 3.4Ghz or so once the workload gets going.

Well I’m now having problems with my Enermax Liqtech TR4 360mm AIO

Prime 95 Blend in April ran at 67.5C with an average clockspeeds of 3.8+GHZ

Prime 95 Blend Today ran at 67.5C with and average clock speed of 3.1+ GHZ

Unloaded temps have climbed from 35C to 48C.

I’m also occasionally hearing a chattering noise which I think is the pump.

I’ve read around the Internet that a significant batch of these AIOs had corrosion problems. (My first one was leaking in the box and I had to RMA it)

So I’m thinking of going Noctua U14 TR4 while getting an RMA.

 

[Markfw]

Well, this was well timed. My first (of 3) Enermax 360 TR4 must have failed. Not leaking, but its 84c at idle in bios ??? and when booted the CPU runs at 500 mhz (0.5 ghz) when its supposed to be at full load. I order a Noctura, but it won't be here for days.

You know I was concerned about this before I bought it.

Gamersnexus did a tear down and they noticed some discoloration in the microfins.

I’ve read online that some folks have drained the system, flushed it, and replaced the fluid with non-corrosive fluids meant for copper/aluminum custom loops.
