Updated with a video above showing the final setup, benchmarks and game tests.

This one is kinda special as it's happily running over PCI 3.0 x4 in an m.2 slot. Set up is problem free apart from needing to disable the intel HD graphics as some sort of conflict causes slow down and freezes, works fine once disabled.

 *Updated to show that Hotplug is not capable, which may affect choice of GPU if going for 10xx series*


Original post

Well this is a little odd. I just received what was supposed to be a delivery of a v8 with a m key m.2 adapter and something unexpected showed up in the box. It's a new series v9.0b with dual hdmi inputs on it (I assume for x4 pci 3.0). Looking forward to giving it a test. 

Has anyone come across a v9 before? I can't find any reference to it online.

 


 System

AsRock Beebox-s NUC
i3-6100u
8gb RAM

Has a spare m key m.2 and a sata socket so can squeeze in a 2.5 ssd and still leave in place the wifi in the other m.2

 

eGPU gear

EXP GDC Beast 9.0b M2 x4
NVidia GTX970
220W Dell DA-2 PSU

I did buy the EXP GDC 9.0b from Cloud Hero's.  Package came with the exp gdc, pcie Y-cable, Dell DA-2 PSU and a perspex enclosure. Cost was 668 CNY so translates to about $95USD for the lot, pretty good as banggood are charging about $150. I bought through Taobao. I live in Hong Kong so have a taobao account I buy directly through (I don't speak or read Chinese so was a pain of google translate to set up). Shipping to HK was like $10usd

 

 

 

I've put it in a metal enclosure I had at the moment. Looks quite good I think.

Wow! Nice see through protective cover. Looks right, two HDMI channels, each carrying 2 lanes. Am curious at what link speed you'll manage to get this going. PCIe 3.0 is rated at 8Gbps, with Thunderbolt using redriver ICs to boost the signal integrity. Blus PE4C 4.1 using a soldered cable, previously found to give most reliable signalling. Maybe EXP GDC's Cloud Hero has fixed his Gen2 signalling issues and now moved to Gen3?

 

Please do report your results, and costs. Direct x4 3.0 from the Southbridge, like a M2 slot provides, outperforms Thunderbolt3 since doesn't need to cross multiple bridges, each adding latency.

ok, so it's up and working now in a x4 pci 3.0 m.2 slot. GPU-Z is showing it @x4 3.0 

I have only installed 1 game so far which seemed good and I'll do more game testing at some point. But in terms of bandwidth testing it seems to be where I would expect it:

Average HtoD bandwidth in MB/s: 2967.4 

Average DtoH bandwidth in MB/s: 3076.7

Average bidirectional bandwidth in MB/s: 5259.3

So... if I'm looking at this right that's showing bidirectional bandwidth in excess of 40Gbps.

@stulowe, very impressive numbers, presumably from CUDA-Z.  They are eclipsing Thunderbolt performance which sets in around 2,200-2800MiB/s. Need to clarify if your numbers are in MiB/s or MB/s.

If seeing 3000MB/s it's 3/4 the theoretic max of x4 3.0: https://toolstud.io/data/bandwidth.php?compare=pci&speed=3000&speed_unit=MB%2Fs

Curious, how stability is your x4 3.0 link with NVidia cards and what was the cost of the x4 3.0 capable EXP GDC Beast 9.0b adapter?? Positives there really favor M2 over TB3 eGPU implementations for those with a accessible or spare unwhitelisted M2 slot.

I was actually using a command line tool but here is cuda-z

[CUDA-Z and GPU-Z added to opening post]

package came with the exp gdc, pcie Y-cable, Dell DA-2 PSU and a perspex enclosure. Cost was 668 CNY so translates to about $95USD for the lot, pretty good as banggood are charging about $150. I bought through Taobao.

CUDA-Z bandwidth numbers look fantastic. Which notebook are you attaching to?

Did you buy from Cloud Hero's store? Cloud Hero makes EXP GDC products:  https://world.taobao.com/item/529434284683.htm

Westerners buying from taobao via say yoybuy.com get charged by weight. The Dell DA-2 is heavy. How did you manage to buy the package with Dell DA-2 included with reasonable shipping costs? Or did you pay high shipping cost?

I'm attached at the moment to an asrock beebox-s NUC with only i3-6100u and 8gb ram. Nice though as it has a spare m key m.2 and a sata socket so can squeeze in a 2.5 ssd and still leave in place the wifi in the other m.2

i did buy from cloudheros store but I live in Hong Kong so have a taobao account I buy directly through (I don't speak or read Chinese so was a pain of google translate to set up). Shipping to HK was like $10usd

@stulowe, looks great and well priced.

I've updated the opening post with the details during our discussion. If you'd like to take some pics of the rig, add a couple more benchmarks and any special instructions to get it all going then we'll have a an implementation writeup wrap. Nice NUC + eGPU for not much $$.

@stulowe, can't thank you enough for submitting this pioneering work. Your rig one with a high power-to-weight ratio.

My only concern being whether your system would be affected bt the GTX10xx non-hotpluggable error 43 driver issue discussed at https://egpu.io/forums/expresscard-mpcie-m-2-adapters/nvidia-is-killing-off-mpciengff-m2-egpus-error-43-with-372-90/ ??

Did you want to check your eGPU hosting port's hotplug status using hwinfo64 as shown on this link and make a comment in your opening post? If it's hotplug disabled and GTX10xx cards are off limits, it could be a deal breaker for some looking to replicate your rig.
