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.

I've also considered using that PSU for my Node. I was trying to find a way to get an extra Corsair compatible PCI-E cable but your approach of using an adapter makes more sense considering it should be easier to get a hold of. I'll have to find a place to get a PSU Bridge though. But I guess a paperclip can work in a pich as well?

Everything you need is ready to ship on Amazon; PSU, PSU bridge/jumper, Corsair 8 to 6/2-pin PCIe power cables.

Hmmm, I've been running my 1080Ti in a stock Node for some weeks now, worked hard for long periods of time, and have had no stability issues.  Maybe the issue is with OC'd cards?  Dunno.

Hey ! – hows your set up now ?

I have late 2016 MBP 15in touch with AMD 460 – fresh bootcamp anniversary – no creators update

Having same issue with complete shut down of Akitio Node TB3 with EVGA 1080 Ti iCX

Sounds like like power supply. But Just wanted to check in before I order. I live in Japan so I have to import this stuff. Time and money. So any heads up would be great!

Thanks in Advance egpu.io is the place to be!

Hey guys, I'm doing fine here, I have 1080ti ftw3 evga. I have had a crash only twice and I believe it is due to overheating, not over-wattage. I did a test, I have overclocked my gpu to the max, 117% power and 85c temperature, with +35mhz core clock offset and max fans once 75c is reached and I have max voltage applied. using the cmd: nvidia-smi -i 0 --loop-ms=1000 --format=csv,noheader --query-gpu=power.draw I can watch exactly what the power consumption of the gpu is and the max I got with OC and max fans is around 335w power consumption at 77c temperature. I also live in a tropical country and it is about 28c ambient temperature year round. I also did the test with my AC off, but the ceiling fan on. I had stability for at least 30 mins, then I terminated the test. Thus the power consumption should be below the 375w max that the akitio node can deliver to the gpu for you guys. However, my feeling is that the PSU has a 80c temperature shut off. Therefore once the internal temperature of the PSU reaches 80c, we get auto shut off. Therefore make sure you have max fans on before 80c because we need to keep the PSU cool. I also have the front case fan running stock. No modifications to the akitio node

 

A side note. Tomb raider rise of the tomb raider has GPU issues! I too have crashing of the akitio node with only that game. The solution for me is to down-clock my gpu core and memory clocks by 200mhz! Clearly that game was not designed well for PC. My feeling is that the game was made for consoles then ported to windows. However since PCs have gpus with higher clock rates the game sends a crash signal to the GPU for some reason (failed programming logic :(....) 

So to play tomb raider rise of tomb raider, down clock your GPU for that game only. For other games make sure you have good air flow to the PSU. 1 time my GPU crashed in GTA5 and the akitio node was almost too hot to touch! However note that I had placed the akitio node almost flush against the wall and it was behind my monitor under my shelf....... So I think that was my fault because the akitio node couldn't breathe at all!! Now it is on the floor, with lots of breathing room. I use the 2m thunder bolt 3 cable (cable matters brand) The other time it crashed was mining at the 117% overclock without maxed fans (in floor position).

Likely the PSU has a lower temp threshold than the GPU. 

 

Other than that... the akitio node has been great to me!

 

Good luck!

Update: While playing GTA 5 for about an hour, with the gpu set at 117% power, the node turned off. It appears the node can only handle 100% power with a 1080ti with stability. Note however that I still have the voltage maxed and a +35mhz gpu core offset. So in game I'm able to pull 2 GHz core clock, stable without crash at 100% power. 

Thank you,
