Intel NUC D33217CK + GTX750Ti@10Gbps-TB1 (AKiTiO Thunder2) + Win10 [Yukikaze]

Recommended Posts

This is probably the simplest eGPU setup I've dealt with so far. It is also rather silly, since the CPU is definitely the weakest link here. An Ivy Bridge i3 at 1.8Ghz isn't going to push high frame-rates in gaming, after all, and the performance improvement definitely doesn't justify the cost. An actual use for something like this would be to add HEVC decoding abilities to an existing NUC. Just use a cheaper enclosure (such as the 140$ Thundertek one) or opt for mPCIe instead of Thunderbolt to keep the price as low as possible. Obviously the GTX750Ti I used here doesn't decode HEVC in HW, but I suspect a newer low-range video card will work just the same and will do so.

 

I guess I just had to try it. Anyway:

 

Computer Components:

Motherboard: Intel DC33217CK (CPU: i3 3217U @ 1.8Ghz)

Case: Silverstone PT14 Aluminum NUC Case

Memory: 2x4Gb DDR3 1600Mhz

Storage: BP4e V2 120GB mSATA SSD

Power Supply: FSP 65W NUC PSU

OS: Windows 10 64-bit (with the Anniversary Update installed and completely up to date)

 

eGPU Components:

eGPU Enclosure: Akitio Thunder2

eGPU Power Supply: 180W Dell Adapter (this is the one that came with my PE4C ages ago)

eGPU: Gigabyte Low-Profile OC GTX750Ti (60W TDP BIOS Mod)

eGPU Thunderbolt Cable: 0.5m Apple TB Cable

 

This is a truly "this just works" setup: Plug everything together with the NUC powered off, boot into windows, wait for the drivers to get installed, reboot if required, switch monitor output to the eGPU, done.

 

Note: The card is reporting an x4 2.0 PCIe link - This is incorrect (the DC33217CK only has a Thunderbolt 1 controller) and CUDA-Z confirms the transfer rate to be about half of what my Thunderbolt2 ZBook gets. This means that GPU-Z is not a reliable indicator of the actual PCIe link established.

Nice that it's all PnP. Wonder if Intel made it that way?

 

GPU-Z is indeed correctly reporting a x4 2.0 PCIe link to the AKiTiO Thunder2 TB1 bridge. That bridge connects to the NUC TB1 bridge at 10Gbps downstream. Hence the disparity between the performance when compared to your TB2 ZBook which too uses a x4 2.0 PCIe link but a 16Gbps-TB2 downstream link.

Yeah, I figured it has to be the PCIe switch of the Akitio that is causing this discrepancy, still - It is not correct on the end-to-end scale, but GPU-Z has no way of knowing that.

Some pictures of the now permanent setup hooked up to my TV: NUC+Thunder2+Audio DAC.

Hi,

 

I have a similar configuration, using a 13 MBP and a NUC DC3217BY with a Thunder2 and a gtx970 Jetstream.

I have some questions, first, shall I use the HDMI on the NUC or on the card? About now I'm on the NUC port, and -second- i'm experiencing problems in installing the drivers.

I tried several times by deactivating internal graphics, installing uninstalling and so on.. but shame on me I've not tried to plug the HDMI of the card.

UPDATE

 

i tried this but nothing good happened. The driver installs but after the reboot, nothing displayed. I connected the NUC with teamviewer at another pc and I  manage to open the device manager, which displayed the 970 in the graphic cards BUT with the alert yellow triangle (error message in italian: "Il dispositivo ha riportato un problema ed è stato interrotto. (Codice 43)" ||in english shoub be Windows has stopped this device because it has reported problems(Code 43) )

Any help would be appreciated

Tried the TB/mini DP capability of the NUC with an HDMI adapter and it works flawlessly. Intel keeps saying that the tb controller isn't capable to handle a tb2 device.

Egpu setup still works great with my tb2 MBP mid 2014.

C'mon guys don't leave me alone!

      Hi!

      So, i got a strange situation here. I have an old Asus ROG G751JM laptop connected to an old Samsung monitor (Model S20C301L) through a VGA connection.
      This monitor supports both DVI-D and VGA inputs, while my laptop can output through VGA, HDMI or Thunderbolt/Mini DIsplayport. I wanted to upgrade to digital signal, so i bought an Thunderbolt/Mini DIsplayport to DVI cable.
      At first, it was a nightmare. There was absolutely nothing i could do to get it to work. I spent hours troubleshooting, but the monitor just could not detect any signal, only VGA one. But then this happens.
      I was testing with only one connection at once and i got tired of plugging and unplugging the cables every time. So i had the idea to keep both cables plugged in and change the source detection in monitor's menu when i wanted to. So, with the TB/MiniDP cable already connected, i've then connected the VGA cable (while DVI was selected as input source). The display started flashing. After 2 seconds, voilà, it was working. And i was like, "what the f***???" I've then unplugged the VGA cable, signal lost. Plugged it again, got digital signal.
      Well, i'm happy that it's working now, but i simply don't understand what's happening here. Why is that i need both connections simultaneously to make it work? WIll that still happen if i use a HDMI to DVI cable?
      Fun fact: the image displays only after windows startup. So, if i want to enter BIOS setup for example, i need to switch back to VGA as input source.
      Sorry for my english.
       
      Update: Can't run games with It, i get bsod.

      Hi, just a quick question what would be the best EGPU adapter, because i see the really expensive ones but then you have the 400$ dollar one that Lowspecgamer used. Which do you guys recommend ?

      I  discover that there is an Akitio 2, wich can use with iMac 2013 for productivity increase. I want to use akitio 2 with GTX 1050 ti 4Gb, but i dont know how it is intalling on iMac?
      Who can write for me the process of installation ALL equipment (akitio 2 + GTX 1050 ti + imac)? What i must to do? I talking about from the very beginning to the very end. 
      PLEASE everyone, help me. You are my last chance !!!!
