Description

This is a multi purpose system I have just rebuilt. It will be used as daily driver, gaming, VR and primarily as a Milkyway@Home BOINC compute box.

There are actually two Titan V's in this build but PCPP doesn't let you add two, most likely because they don't SLI. In compute though, both GPUs act independently and you don't use SLI/Crossfire even when it is possible.

Milkyway@Home is a double precision (FP64) distributed computing application which loves the Titan Vs. Each Titan V produces 6900 FP64 GFLOPS (compared to 350 for a 1080Ti or 790 for a Vega 64).

For VR a Vive Pro Kit is used and gaming is done 4K @ 60Hz which suits the titles I play (mostly grand strategy).

As this is primarily a 24/7 compute box, everything is run stock except for a custom fan curve on the Titan Vs for more aggressive cooling, and a mild system memory OC. There is an Eaton 900watt/1500VA UPS for each system.

More info on Milkyway@Home here: http://milkyway.cs.rpi.edu/milkyway/ GPU FP32 vs FP64 info can be found here: https://www.geeks3d.com/20140305/amd-radeon-and-nvidia-geforce-fp32-fp64-gflops-table-computing/

Last screenshot is of thermals after a few hours of standard MilkwayWay@Home load, on a mild spring day.

Edit: I have since replaced the rear exhaust and AIO fans with Noctua NF-A14 industrial 3000 PWM fans. Thermals were previously fine for early Spring in Australia, but I wanted to get ready for the coming Summer temps.

How hot does the computer get? Just wondering how it fairs without liquid cooling.

setibox submitter 2 Builds 1 point 1 month ago

Thermally it is actually quite good, likely because it is run at stock to keep temps down/extend life.

Under BOINC load the GPUs sit between 52 and 59 degrees Celsius (fans 3000 to 3200 RPM) and the CPU sits on 60 degrees Celsius.

Because the H115i Pro 280mm radiator is on the front intake, if I were overclocking the 1950X and throwing a lot of heat out, it would likely have a large effect on the GPUs "downstream". Running stock seems fine tho.

What's the small card underneath the top Titan?

setibox submitter 2 Builds 1 point 1 month ago

The ROG Zentih Extreme MB box comes with a 10Gbps network card included: https://www.asus.com/Motherboard-Accessory/ROG-AREION-10G/

pros: your pc is a beast and can run any game over 150 fps on any setting cons: it will cost you your life and soul to buy it

Something people like us we'll never have :(

It isn't a smart build just for gaming though, a well specced 8700K @5GHz with a single RTX2080Ti would outperform it at gaming for much much less.

The majority of the expense went into buying GPUs which only make sense if you need FP64 compute power, or tensor cores.

Is it possible to build this same build with the open layout of the r6?

setibox submitter 2 Builds 1 point 1 month ago

The problem with the open internal layout config of the R6 is that the Zenith Extreme MB is EATX form factor and blocks the main cable management grommets. Also the flat ribbon power cables of the Corsair AXi series do not make for easy alternate route cabling.

If going for open layout I'd try to stick to one of the ATX form factor boards and a PSU without ribbon cabling and/or utilizing custom cabling.

Ditching the optical drive of course and maybe using SSD secondary drives rather than mechanical would help also.

Thanks a lot for the info!

@setibox Where were you able to find the TR4 mounting bracket for the Corsair H115i Pro?? Cannot find any in stock in the U.S.

Corsair's site says their Pro RGB line of coolers works with Threadripper, but it doesn't ship with the TR4 bracket. The former models that released last year that work with the bracket from AMD appear to be discontinued. You think they would have the bracket in stock considering the redesign of the coolers and the fact that the TR4 socket has been out for a year now.

Even Corsair's site has been out for a long time now.

Ahh I see you are US based, ignore my message as I got mine in Australia from PCCG. They are out of stock now but Mwave and Scorptech still have them, but don't ship internationally.

If the US supply chain has dried up maybe look at other country stores that have them that will deliver internationally? The Aussie stores here don't ship outside of AUS/NZ but maybe from a Euro location?

Functionally wise the H115i 280mm works great if you can source a bracket kit, especially since the Enermax Liqtechs have quality control issues - mine died in under 3 months and I have read many reports of others in the same boat.

I have also heard counter reports that the second gen Liqtechs don't have the same QC problems as first gen, but I haven't personally tried one.

Thank you so much for replying with the insightful information! I've made contact with Corsair and I was told that October 25th the special order bracket (CW-8960054) will be available.

The communication about the need for the bracket is unclear on the Corsair site. PCPartPicker is the only site that really brings this to your attention when you are compiling your build list.

Hello mate, 1 month after, how did the titan V go, in terms of temperatures? Was it still okay? What are you min/max/ave during loads?

setibox submitter 2 Builds 1 point 3 days ago

The third pic was taken after sustained load with the more aggressive fan curve applied, and that is pretty average temps for the Titan Vs. Around 56 to 58degC average with the odd spike up to 60degC for the top card and 62degC for the bottom card. The absolute highest temp I have seen on either card is 64degC.

This is running MilkyWay@Home though, 4x work units at a time per card. This doesn't yield a solid line at 100% GPU utilisation, so it would likely be higher temps on a project that could completely saturate the cards (VRAM is the limiting factor for how many concurrent work units that can be run at a time).

(Unfortunately I don't have temp data for other loads as all the other projects I crunch are FP32 and are run on a much cheaper Vega 64 box)

It is also very quiet under GPU only load, but once the CPU is loaded up the 3000RPM Noctua industrials really kick in AND THINGS GET A LITTLE LOUD.

Most expensive build on PCPP. U must be loaded with money.

I am not a fan of LED/RGB but it is not worth the effort it takes to avoid it on decent gear, it is everywhere. Besides, after it is thrown in a blackout case you can't tell it looks like a unicorn stepped on a landmine inside.

Cabling is ugly but functional given I need to strip my systems down for dusting every 4 to 8 weeks, because full load 24/7 moves a ton of air through the systems. Like you said, it is all hidden away. I used to care a lot more about cabling the first dozen or so times I redid it.
