I'll have to take a look and see if those extenders work on the 1080ti card.

Now if I can get a third card connected to the motherboard, the only other concern I would have is how to mount it. Is that something I should also look into or can this card be connected and remain 'loose' inside the case? That has me worried.

You are MUCH better off using the available slot on the MB and modify the USB2 cables (if needed) than using a PCIe extender.
It will fit as long as the MB cables can do a right angle in about 5/16 inch.

I use one of this pin extenders on the USB 3.0 port in my 4xGPU host to allow to use the last slot for the 4 GPU. Works perfect.

Thanks for the recommendations. Will advise once we reach that point. But for now,

UPDATE!

So we tried Linux via Ubuntu and all I can says is... I gave up. It took four hours just to get Boinc running on the OS and the darn thing wasn't using any of the GPU cards. So we threw up out hands in defeat and decided to get Windows 10 instead. Once we get everything running, we'll just run Linux over WIndows 10 and figure it out from there.

So here's where we're at right now with this newly built computer.

AuthenticAMD
AMD Ryzen Threadripper 1900X 8-Core Processor [Family 23 Model 1 Stepping 1]
(16 processors)

[2] NVIDIA GeForce GTX 1080 Ti (4095MB) driver: 385.54 OpenCL: 1.2


So the team's page lists the two Graphics Cards successfully, but I think I've stumbled into a block. I don't think BOINC is using the graphics cards at all. Here are the details I've gathered from it's progress page.

Measured floating point speed 4.78 billion ops/sec
Measured integer speed 19.1 billion ops/sec
Average upload rate 32.46 KB/sec
Average download rate 458.6 KB/sec


Do these specs looks appropriate for the system we got here?

TL:DR

How do we tell if it's using the cards? And the BOINC program also suspends itself when I tell it not to suspend in the options.

Those are simply the CPU benchmarks and upload/download speeds. Nothing to do with the gpus. You need to post the first 30 lines of the Event Log after a fresh start of BOINC to determine whether BOINC is seeing your gpus.

Yup, ok.

Looks like it has seen you config and should be using both GPUs

To run the GPUs all the time, you to advance view of the BOINC and select activity and on the pull down select RUN always and Use GPU always that way it will never suspend the GPUs. This may affect your responsiveness but should keep the GPUs running

I take it you tried using the BOINC Install from the Repository? If so, your experience is common. That's why I built the BOINC All In One Package for Ubuntu. All you have to do to get BOINC running is Install the OS & Driver, Download the AIO package and unpack it to your Home folder. Read the ReadMe for the Library Links, place the Libraries in the setiathome.berkeley.edu folder, then Double click on boincmgr. It shouldn't take more than 30 minutes to Install Ubuntu and have BOINC running the Special CUDA App. The biggest point is you need to start with a Clean install, Old Configuration files from the Repository BOINC may cause trouble, so, best to Erase the Old System.

The Download is here, BOINC All-In-One Build to run zi3v CUDA 8.0 in Ubuntu 12.04 to 17.04
The CUDA Special App is around Twice as fast as what you can run in Windows.

I looked at the dual 1080 computer and it shows this.

windows_intelx86

so yes it is using the GPUs.

First, thank you TBar for that recommendation. When we try Linux again, I will do just that.

And second...

To run the GPUs all the time, you to advance view of the BOINC and select activity and on the pull down select RUN always and Use GPU always that way it will never suspend the GPUs. This may affect your responsiveness but should keep the GPUs running


View... The 'View' pulldown window is how you access those commands. Not in settings, but view.

AARRRRGGHGHHG!!!!!!

That is the worst design ever. I showed my Dad those very steps and he didn't even know they existed! We're honestly disappointed by this revelation because we never would have figured out that we needed to go through 'view' to find these options. Thank you Zalster for telling us this.
