Advice needed for crashing Akitio Node

My setup:

  • Macbook Pro 15" (Radeon 455 version)
  • Akitio Node over TB3
  • MSI GeForce GTX 1080 Ti Gaming X 11G
  • Windows 10 Bootcamp (fresh install of anniversary edition, then creators update applied)
  • 60hz 4K monitor (Samsung U24E590D) connected by Display Port

After getting sick of all the hacking required and performance loss when accellerating the internal LCD I decided to get a 4K monitor and attempt to enjoy a setup with no extra hacking required. Simply installed Windows 10, booted it up with the Akitio Node connected and installed nVidia drivers and MSI's Gaming apps etc.

At first everything seemed fine. Playing Elite Dangerous for a bit in buttery smooth 60fps framerates. Then after about an hour of playing the Akitio Node just powered down in, crashing the game. The Node can then be rebooted after a few seconds of "cooldown", at which point the PSU appears to be blasting the fans at max speed for a while. Rebooting the Macbook and restarting the game works but appears to consistently crash after about an hour in game.

Today I attempted playing Rise of the Tomb Raider which puts more strain on the GPU and that crashes consistently after only 3-5 minutes.

I've done some activity logging using GPU-Z and would say that there is a clear correlation between stress on the GPU and how fast it powers down. For example the TDP strain playing Elite Dangerous is around 75% while Tomb Raider is between 90-100%.

One hypothesis is that the PSU can't handle the load but I don't know how to verify that. Last time it crashed GPU-Z was showing only 60% TDP usage which isn't much... Also I haven't heard from any other Node + 1080 ti owners complaining?

Any idea for how to troubleshoot this one?

I have a Node with an EVGA 1080 Ti SC2 Gaming, I've played numerous games (Elite, Star Citizen, Talos Principle, etc) that drove up eGPU utilization and the fans kicked on to a higher speed but I never had any issues with anything shutting down.

Are you sure the Node is completely powering off and not just the GPU?  Possibility the GPU is overheating because it's not getting enough airflow and the Node is staying on?  If the Node itself is shutting down (No more blue light, no more PSU fan, etc) then it sounds like a bad PSU.  The 1080 Ti TDP is well below the PSU's rating.

Typical PSU Over Current Protection; simply need beefier power supply.

I had the same issue with my Mac and original power supply.  It actually happened after I installed a new power supply (600W) as well (Hooked up to a MBP 15 Radeon Pro 460).  I have since moved it to a Skull Canyon NUC using a CalDigit active cable and haven't had an issue since.

Yeah the whole thing is powering down. I have to switch off / on the PSU after a cooldown period to get it to boot up again. Maybe I can find someone nearby to borrow a PSU from to test it out...

Are you saying that your Node was still powering down even with a 600w PSU?

But the Skull Canyon device didn't have the power down issue? Even with the original PSU?

If you couldn't get the Node to stay running even at 600w then it really doesn't sound like the PSU was the problem to begin with? What GPU were you running?

Hi.  I never put the original PSU back in.  But correct, power down issue with both PSU through the MacBook Pro 15.  No issues with Skull Canyon.  Gigabyte Aorus 1080 Ti.  

 

Edit -  I also haven't gone back to the Akitio cable as it was too short for where I moved the node with the Skull canyon.  So it may have been the cable and not the Mac.  I've had no issues with the Caldigit active cables.

I'm having the exact same issue.

Some games run completely fine, but others cause the entire Akitio Node to shut off. It turns back on without a problem after cycling the power.

I was running GPU-Z during the latest crash, and the highest value I saw right before it before it stopped was 87% TDP strain. It seems like it must be the PSU, but I'm not certain.

Let me know if you find a solution! I'd prefer not to spend another $100 on a better PSU.

Games:

  1. Prey - Haven't had any issues.
  2. Overwatch - About an hour.
  3. PUB - Crashes on launch.

Update

I ordered a Corsair PSU that will arrive tomorrow. I'll post again after I test it out and let you know if it resolved the issue.

Working now!

Ordered three items:

  1. Corsair SF450
  2. PSU Bridge Tool
  3. 4-Pin Molex Male to 6-Pin PCI-E Female Power Adapter Cable

Everything is stable now, and the crashes have stopped. An added bonus is that the Node is much quieter now, and the PSU fan only turns on when it needs to.

Here is an update regarding these issues. I opened a ticket with Akitios support and they decided to order exactly the same card I was using to see if the PSU was indeed the problem.

Today I received their test results:

I have some good news and some bad news. The good news is that we were able to reproduce the problem. With the current 400W PSU, when the card is under heavy load, the overload protection (not over voltage protection as mentioned earlier) kicks in and cuts off the power. The bad news is that this means we have to add this and possibly other GTX 1080Ti cards to our list as incompatible. We are currently further investigating this issue and will likely upgrade the PSU in the future to also support GTX 1080Ti cards. Unfortunately, in you case, that means you would have to either use a GTX 1080 card instead of the Ti card or replace the power supply yourself if you happen to have a spare PSU at home. An SFX power supply will fit into the Node but if you leave the case open, you could also keep using the built-in PSU for the Node and provide power to the graphics card from a secondary PSU.

So looks like 1080 ti cards are a no go with Akitio Node (if you don't have the problems it's likely due to your particular PSU having unusually high quality by the luck of the draw).

Another thing I noticed is that I can get my Node to run fairly stable by manually underclocking my 1080 ti using MSI Afterburner software.
