Considering new Threadripper system

Sat Dec 15, 2018 5:28 pm

Hi everyone. I'm considering building myself a Threadripper system, but it's been a long time since I've built a computer.

(I think the last computer I built was an Athlon XP 2400+ with an ASUS A7N8X Deluxe nForce2 motherboard and a Radeon 9500 Pro. That would have been around 2002.)

Since then, I haven't had the money to buy a desktop *and* a laptop, so I've been using laptops since then. Now, I finally have the money to build a desktop again. But since it's been so long, I want to make sure I'm not forgetting something.

Use case: mostly word processing and light gaming. (I currently have a laptop with a dual core Core i7-7500U and a Geforce GTX 950M. I can run most of my games on medium settings.) But I occasionally run statistical regressions that take about 5 hours on my 4 core desktop computer at work. My statistical software is highly parallelizable, so it ought to scale almost linearly with core count. I probably don't really need a Threadripper, and this is mostly just for a wow factor. But a Ryzen 2700 with an X470 isn't so much cheaper, so I say heck, let's have fun. YOLO!

(I could save about $170 by going with an X470 and $400 by going with a Ryzen 1700. That would drop the total price from $2805 to $2235. To me, that's not enough of a difference to justify cutting the core count in half.)

Here's my parts list so far, with commentary:

Gigabyte X399 Designare EX (rev. 1.0)
There's no such thing as a low-end Threadripper motherboard, so the differences among motherboards are small, and this was a hard choice. But I chose this motherboard because reviews say it is designed for reliability and stability, not overclocking. The metal reinforcing backplate and the active-cooled VRMs, for example, are nice touches. One review noted it has more thermal sensors than almost any other motherboard.

Threadripper 1950X 16-Core
'Nuf said.

32GB (4 x 8GB) DDR4 2666 (PC4 21300) 2Rx8 (dual-rank) ECC Unbuffered by NEMIX RAM
The fastest unbuffered ECC DDR4 I can find. If anyone knows of anything faster, tell me. The motherboard supports up to DDR4 3600.

Seasonic Prime Ultra 1000W 80+ Titanium power supply

Enermax Liqtech TR4 II 280 Addressable RGB AIO liquid CPU cooler

Samsung 970 EVO 2 TB

ASRock Phantom Gaming X Radeon RX 570

be quiet! DARK BASE 900 ATX Full Tower
I wanted a case with noise dampening insulation. And I didn't want a tempered glass window because I suspect that doesn't dampen noise as well. So that limited me to this case and the Fractal Design Define R6. It was a tough choice between the two of them, but I went with the be quiet! because its side panel can accept a fan aimed at the graphics card.

The case comes preinstalled with two 140 mm intake fans and one 140 mm exhaust fan. Combined with the two exhaust fans on the CPU cooler's radiator, and I figure that's probably enough cooling. Especially since I'm not overclocking. But maybe I should install some extra intake fans in order to create positive pressure and prevent ingress of dust? (The case has filters.)

I also own several sets of screwdrivers and bits in just about every size, from jeweler's on up. I'll also buy some ESD tweezers, an ESD wrist strap, an ESD mat, and a headlamp.

I'll probably buy a 2 TB mechanical hard drive as a backup drive.

I already have a monitor, keyboard, and mouse.

Anything I'm forgetting?

Thanks!!

Do you have a SKU for the RAM? Threadrippers are fussy about memory. You really want compatible (tested by others not yourself) B die Samsung based modules.

Good call!! This is the product: https://www.newegg.com/Product/Product. ... gnorebbr=1

I couldn't find an SKU, but this came up: https://www.phoronix.com/scan.php?page= ... C-DDR-Fail

Looks like I'll have to reconsider that RAM. Thanks!

Always check to see if you can't accomplish your processing with a good GPU.

-even if you can't, you might consider waiting some. :oops:

The next AMD grouping seems poised to have part of its architecture on a lower "process", which could pay "dividends" in several respects (..including higher core-count).

I checked, and the maker of my statistical software (StataCorp) says they have zero plans to use GPU processing.

As for waiting . . . yeah, I see the wisdom in that. But then again, there's always something new every year. If I keep waiting, I'll never buy anything, ever.

Wait, Gigabyte has a PDF of all the specific models of memory they support, including ECC. Thanks for inspiring me to look this up!!!

Ooh, and on Kingston's website, they have a page for this specific motherboard! https://www.kingston.com/us/memory/sear ... gnare%20EX

That seems a bit extreme. Wouldn't something like a $115 Focus Plus Platimum SSR-750PX do the job?

Re: mechanical hard drive: good point, thanks.

Re: power supply: I chose 1000W because I want room to upgrade. As configured, I'm using about 500W, give or take. But in a few years, if I add 4 sticks of 16 GB RAM and an RX Vega 64 (or whatever the equivalent is in a few years), and a few extra hard drives, I'll be around 750W. So by getting a 1000W power supply, I ensure that I can load the computer up with the most RAM and GPU and still not have to upgrade the PSU. http://www.coolermaster.com/power-supply-calculator/

Graphics card: yup: https://www.newegg.com/Product/Product. ... gnorebbr=1

You may want to reconsider that Enermax Liqtech AIO, it has a ton of bad reviews mostly due to it clogging up and failing within 6 months or so. Many reviews mentioned going through multiple RMAs, and each replacement unit failing the same way. I would do some more research before dropping the cash on it, as there was a large thread on HardOCP about it.

STOP. Do not pass go, do not buy non-samsung ram. Especially if it is ECC on TR.

8GB SR: m391a1k43bb1
16GB DR: m391a2k43bb1

The speed grades basically don't matter, because these are B-die.

Samsung B-die does not cost more in the server world, and even the "2133" DR ECC kits will run 2933 just fine. The SR can do 3200 14-14-14 in a 4x8 setup.

One of my fully populated TR boxes (8x16GB) is a hodge-podge of used 2133 and 2400 sticks I randomly snapped up on various ebay deals.
Saved nearly half the cost in the end compared to the other system with all brand new sticks. Cannot tell them apart, both chumming away 128GB 2933 16-16-16 1.35V under heavy load.
2018: at 120 Zen cores and counting, so pretty much done with intel on the desktop.
E5 2696v4 22c44t 2.2~3.7Ghz - The last great gleam of the pre-nerf HEDT era.
E5 1680v2 8c16t 4.5Ghz - "Yes Virginia, there were unlocked xeons" /weep for them.

Thanks!!! I can't find the HardOCP thread you refer to, but I found one here making a similar point: viewtopic.php?t=121071

That's a real bummer, but I'm glad you told me!!!

So I'll go with an air-cooler, then.

This Noctua NH-U14S TR4-SP3 cooler seems to be the largest TR4 air cooler I can find: https://www.newegg.com/Product/Product. ... -_-Product

It has clips for a second NF-A15 fan, so I'll get that too.

It has to be Samsung? It can't be, say, Micron?

I'm looking at the motherboard manufacturer's memory compatibility list, and it specifically lists non-Samsung memory: http://download.gigabyte.us/FileList/Me ... -ex_v1.pdf

I run g.skill ripjaws v, 3200 mt/s 16 18 18 36 timing (aka Hynix) and it works fine on my x399 Taichi +Threadripper 1950x.

The only issue was that the first batch they gave me was fully defective(failed after 10 runs of Memtest86, so I forgive them for that). An RMA later, and my system is rock solid.

I second this recommendation! i am waiting for the 16GB sticks to stabilize and will buy 2 of those.

Thanks everyone. In the end, I decided to go with a Ryzen 7 2700X over the ThreadRipper 1950X. I decided that the XFR2 and Precision Boost 2 would benefit me more often than the extra 8 cores. And a ThreadRipper 2 was just too expensive.

Anyway, I bought 2 sticks of 16 GB Kingston ECC. The Kingston RAM worked out of the box, and interestingly, overclocking it from stock 2666 MHz to 3200 MHz had no effect on performance: viewtopic.php?f=36&t=121626
