1950x for a good (UBT) home

Having problems installing that new stick of memory? Found some great software or having issues with something? Or maybe want to chat about your PlayStation, X-Box, Nintendo, Sega, even your old Spectrum 48k....! Or maybe something you want to sell or acquire (computing related of course!). Let us know here...

1950x for a good (UBT) home

Post by damienh »

Hi Folks,

I found a second hand 2990wx so have swapped that in for my 1950x. That means that I have a 1950x 1st gen Threadripper available at a discounted team price, if any of you want it.

I'm sure you all know enough about hardware to go and read some reviews, but this is the 16 core / 32 thread part and its default clockspeed at full load (under good cooling) is around 3.7GHz, although it can vary.

The chip has done a fair amount of crunching, but also has lived under a good water cooled setup and never overclocked. I bought it new/retail at release, almost certainly from Scan (if not Scan, then it was Overclockers). It will have plenty of life left in it.

The lowest domestic sold ebay price for this of late was £295, so I'm happy to part with it for a UBT team member at £150 including postage. I still have the retail box and the required TR4 socket key.

Let me know if you're interested - first come first serve.

Cheers.

The 1950x is an excellent chip; I can confirm this as I currently have two of these running.

The same thing goes for the price, £150 is an excellent price. If I were not currently reviewing my financial situation then I would have bought another for sure.

Hi Damien,

Give it a week or so and if no-one else claims it then I'll take it off your hands, I was planning on an AMD build in the new year anyway :D

Hi Damien

Thanks for making this very generous offer - seems like a great deal for someone - and I hope there is someone in the team who will bite your hand off for it !!

Since there are no other takers, Mark has confirmed that he will take it. I'm sure it will crunch many a project for UBT in his hands ...

Hi Chris, I've got an Arctic Freezer 33 TR (the white variant) It's supposed to handle up to 200W TDP but there's mountings and fixings for a second fan if I get ambitious :)

That's actually the cooler that I use also; I added a 2nd fan though which if I remember rightly I bought online from the Arctic website.

I think the reason I did that was because it was getting close to the 68c thermal constant when running AVX projects, while in a 4U server chassis.

Good to know, thanks. From what I can see, any second fan will fit on for now, I can order a proper second one if need be. QuChem doesn't seem to make the CPUs run too hot though which is where it's starting off.

HI Mark

Cool - shame it's only validating (and earning credit) on maybe 2/3rds of the tasks and wasting time and energy for nothing on the rest...but that's QuChem for you !!

Hi Tim,

It's about the same ratio as my Windows i7 box .... but four times the throughput :D

Hopefully the native Linux jobs won't get into the same state as the Windows VM ones and end up running for 10+ hours.

Mark

[edit]All my invalid workunits have also been invalid workunits for someone else, usually more than once. I'm blaming the tasks rather than Damien sending me a dodgy CPU :D

All native tasks running to completion, no hanging waiting for memory or unmanageable.

Seem to be slightly slower than my i7 (when it finishes normally!) but that could just be slower clocks.

I'll have a look tonight.

I checked with PSensor when I installed it but it seemed to have two temperatures each for two cores (four readings) I think they were case and junction for core 0 and core 1 or something similar.

If I remember correctly, both "case" were mid sixties and both "junction" were 80/90? Or I could be completely mistaken :)

I was mistaken :oops:

Tctl is 94 degrees
Tdie is 68 degrees

So if I'm reading the specification right, that's the limits and it's throttling.

Think I need another heatsink fan (at least)

Yep, sounds very hot indeed and pushing its max temp (68 degrees according to the spec sheet). I wonder if that’s why you are generating invalid units??

Sounds like you have a Linux box but, if you do have windows on it, try grabbing the Ryzen Master utility. It will give you a much better idea of what’s going on.

On the positive side, we reached #6 top producer in QuChem a couple of days back, and recently took #8 on the FB board.

Once this box is humming away, we will be in a very nice spot indeed.

I did wonder when the heatsink only covered about half of the heatspreader.
I don't think the invalids are related, they've all been tried by someone else and failed there as well.

Checking I get this:

Code: Select all

mark@:~$ sensors | grep "Tdie"
Tdie:         +67.9°C  (high = +70.0°C)
Tdie:         +68.1°C  (high = +70.0°C)
mark@:~$ cat /proc/cpuinfo | grep "cpu MHz"
cpu MHz		: 3187.559
cpu MHz		: 3187.813
cpu MHz		: 3187.988
cpu MHz		: 3186.614
cpu MHz		: 3188.799
cpu MHz		: 3188.590
cpu MHz		: 3188.835
cpu MHz		: 3189.073
cpu MHz		: 3184.809
cpu MHz		: 3184.932
cpu MHz		: 3184.990
cpu MHz		: 3185.087
cpu MHz		: 3185.134
cpu MHz		: 3185.270
cpu MHz		: 3185.347
cpu MHz		: 3184.911
cpu MHz		: 3189.982
cpu MHz		: 3190.178
cpu MHz		: 3190.203
cpu MHz		: 3188.323
cpu MHz		: 3190.438
cpu MHz		: 3190.226
cpu MHz		: 3190.470
cpu MHz		: 3190.741
cpu MHz		: 3186.472
cpu MHz		: 3186.635
cpu MHz		: 3186.689
cpu MHz		: 3186.782
cpu MHz		: 3186.812
cpu MHz		: 3186.963
cpu MHz		: 3187.035
cpu MHz		: 3186.597
So what's the all core turbo supposed to be? Is it actually throttling? - [edit]3.7GHz apparently so it IS throttling :(

Either way, time to wait for in progress tasks to finish, shut it down and add more fans :)
Maybe use some proper heatsink paste as well rather than what came with the HSF?

Most of the QuChem output is down to you :o

New heatsink paste and a second fan:

cpu MHz		: 3413.809
cpu MHz		: 3414.093
cpu MHz		: 3414.215
cpu MHz		: 3414.507
Just within spec but not throttling, 68 degrees and 3.4GHz :)

I think I'm going to look at AIOs or at least, a bigger HSF (although this one is recommended by AMD on their website as being able to handle threadrippers, maybe I'll try playing with fan profiles?)

Yeah, that ran around 3.7GHz most of the time under good water cooling. It did fluctuate a bit here and there.

Looks like there are only a few percentage points in it.

I'm not sure if being right next to the GPU is affecting it either.

Some options to try anyway, there may be some BIOS values to change as well.

3.5 GHz all cores at only 47 degrees, very impressed! :D

Caveat: It is WEP rather than QuChem as they've stopped producing work for the moment and the side was off the case.

Now to see if I can get it up to 3.7 GHz like Damien did.

Edit. Covers on and running for a couple of hours, temperatures have gone up to 50.1 degrees.

I would definitely be interested in what kind of temps you are hitting when running a 100% load of AVX tasks; for future reference.

Also as to what config you went with; push, out of the top (fans) - or pull, from the front (fans)?

Nice work - looking good. I didn’t overclock it. I think you’ll find it hitting 3.7 in many workloads at those temps? I used to run it under windows, but that really shouldn’t make a difference.

Hi Damien,

I was just going by the BIOS that had "Target CPU speed" set at 3.4 GHz. I think I'll have to change the clock ratios to get more than 3.5 GHz on all the cores.

At the moment, it's turning out WEP tasks almost twice as quickly as my 3GHz Xeons :o :)

Wow, that’s great. If they are also 16 core, then I assume it has something to do with feature support (SSE / AVX / etc)??

Hi Chris,

Some experimenting.

I assumed PrimeGrid 321 LLR uses basic AVX as there were some posts about testing AVX 512.
It's not quite 100% load as I have a 1080 GPU in for display purposes and that's got a core reserved while it runs PrimeGrid PPS.

At 4.0 GHz, Tdie temperatures were 105.2 degrees.
At 3.8 GHz, Tdie temperatures were 69.9 degrees.
At 3.7 GHz, Tdie temperatures were 67.5 degrees.

I was very surprised it ran at 4 GHz but quickly turned it down with the temperatures. Might be worth repeating with less demanding (non AVX) tasks?
3.8 GHz was still a bit high.
I've left it running at 3.7 GHz and will check for any failed workunits.

Radiator fans are on full and definitely audible.

So just to confirm your previous results, non-OC running on AIO is: 3.5 GHz @ 44c ?

I don't suppose you did a test on non-OC while running AVX tasks?

Thats pretty crazy how high the temps were for the higher OC's; I would have thought the CPU would have shut the system down if it hit 105c. Perhaps only Intel CPUs do this.. (eg TJMax)

--

Checking my 1950x (non-OC) on the Arctic TR33 (double fans)

>lpcpu | Grep MHz

shows 3.5 MHz

Psensor

shows Tdie 55c

while running AVX/SSE2/FMA tasks

--

Sorry I don't think I explained properly what I was asking about the AIO fans.

Obviously you can setup the radiator fans to either push or pull. Also you can either pull cold air in, or push hot air out, (through the radiator).

I was just wondering which setup you went with?

Hi Chris,

Non overclock (3.5 GHz) on WEP was 47 degrees.
Sorry, I didn't. I'll do some later when these tasks finish.
It was only at 105 degrees for a minute or two before I shut it down, maybe there's some sort of averaging or delay? I'm guessing the CPUs are binned and ran at the sweet spot for that rating. I'll try and do a wider range of non OC and OC on non AVX and AVX tasks.
I only managed 3.2 GHz on my TR33 even with two fans and running non AVX tasks. Looks like you have a good chip there.

I'm sure I responded earlier about the fan configuration but it seems to have disappeared?

Radiator was mounted to the top of the case, fans were mounted below the radiator pushing air through it and out of the top.
There's also a 200mm intake fan at the front of the case and a 120mm fan at the back exhausting.

Okay thats useful to know; don't worry too much about doing anymore AVX test for myself as its just curiosity more than anything.

By the way I just found a document about BOINC Roadmap 2019, so I did a post, which you guys may be interested in:
