Akitio node + Vega 64 Liquid Cooled + Bios Flash?

Hey All, 

 

I am back at it again with another eGPU setup. I have upgraded my Akitio node with a corsair SF600 PSU and am attempting to install a XFX Vega64 Liquid cooled card into it. Space is incredibly tight but it makes for a cool looking eGPU. Now i am faced with an issue that i am not too sure can be resolved, when i plug the Vega64 LC card into the node and connect everything up the fans go at full speed and the GPU is not recognised. Now from memory this means the card isn't getting sufficient power. Now if i put an air cooled vega 64 into the node its happy days and the card boots normally without any issue. If I i plug the Vega 64 LC card into my 5,1 mac pro, it runs without any drama so there isn't anything wrong with the card. 

 

I was thinking that flashing the bios on this card may help? Or is the power issue related more to hardware? Based off what I can see the cards all use the same PCB / Board and have the same device ID so I don’t understand why it wouldn’t be able to work in the node, my plan would be to install say a Sapphire or Gigabyte bios onto this XFX card in the hope that this will resolve the issue, as I have never had any issues with these brands.

 

Any thoughts or advice would be greatly appreciated.

Just in case anyone is thinking about doing a similar build in future, here are my findings. I tried the Vega 64 in the Mantis Venus and everything worked flawlessly, with the only downside being the fact that you can't fit the radiator in this case. I then flashed the card with a Sapphire Liquid cooled bios and nothing improved. I then pulled the air cooled bios from my gigabyte Vega 64 and flashed it on to my LC Vega 64 and there was no improvement. It would seem that the Akitio node isn't providing enough power to the PCIe Slot or the node is missing something that causes the card to not initialise.

Same behavior (fans at full speed) with my XFX (RX480...) and as I know I will never buy again an XFX...  this brand doesn't help you with eGPUs!

Yeah I remember in the early days of egpu.io a few reports of XFX cards not playing nice with egpu’s. Though it sounds like you got further than me. I’ve ordered a Razer Core X to replace my node so I am hoping it works in that.

Exact same with me when I initially tried this setup.

Akitio Node + SF600 + Vega64 LC = no card and full speed fans.

I one-day shipped a Sonnet Breakaway 350 Box the next day. 
Installed the SF600 into it. Then the VEGA64.

Everything worked like plug and play. 

Now a Strix Vega56 works in the exact same Akitio Node which I am using for home use, just not the 64 LC. 
The BB w/ 64 LC is being used at the office. 
Both daily with zero issues.

Well, I did run the Vega 56 Strix on the stock Akitio Node PSU for maybe a week and the power supply popped and gave up the good fight.
I ordered a 2nd SF600, installed and she's working fabulously ever since.

I was running 10.14.4 on both the Mac Pro and the MacBook Pro at the time of testing. The thing that is super confusing is that I have 3 of these cards (1x LC Reference 64, 1x Reference Gigabyte 64, 1x Limited Edition referenced Air cooled 64) and from what I can see the PCB / Board is all identical with the only difference being that the BIOS is different.

Its worth noting that the Node only has one 6 pin power connector which powers the thunderbolt / PCI board vs the regular 24 Pin connector which is found on both the Mantis Venus and Razer Core X

This matches up with my experience. The regular Air Cooled Version works perfectly fine but the liquid cooled version doesn't even boot in the node. Glad to hear that it works in multiple different eGPU enclosures. Looking for to getting this all setup.
