    So recently reviewed PowerColor Devil Box loses about 25% of desktop gpu power (tested with quadcore laptop cpu and even more with low-voltage cpu). Are we going to see same performance form Node?

    Unfortunately pcie x4 is not the case :(

    As i Mentioned earlier,  that will be the case with every TB3 based egpu solution.  

    Check out the difference in scores between TB3 Vs.  A direct connect via m. 2 using a GTX1080 -

  2. First things to check : 

     

    IS you Thunderbolt to Expresscard adapter being detected? 

    Also from the picture i can see that the the CPU 4 Pin isnt plugged in, im not too sure if its necessary or not, but you might want to connect that as well and give it a shot. Make sure you connect it the right way and in the right place.

    Also after installation, did the thunderbolt application ask you to approve the expresscard adapter? And did you cleanup the drivers with DDU and install new ones after that?

     

    Another thing that might have been better is that , instead of doing ExpressCard + TB2 you could have just gone with a TB3 based solution and used that. Something like the  Akitio TB2 PCIe box. Would have been much cheaper and easier to setup.

    It would be nice if you could put Alienware's eGPU to better use an an immensely more powerful machine like your P870DM. 

     

    Yeah I'm looking for a service manual right now. If I don't find one, I'll just order a good multimeter and an AGA in a week or 2 to test. 

    But I'm still looking for the female end of the connector that is preset on the system end of the AW's.

    Yeah, nowadays they have various stages of throttle in BIOS, EC & vBIOS...that just being the hardware side.

     

     

    Tell me about, trying to overclock this 1080, is like learning to overclock all over again.

  5. 30 minutes ago, Prema said:

     


    That's the loop to fool the vBIOS that an EC signal is present...wonder who told them that. ;)



    Your own P870DM is running on my modded EC, otherwise it would throttle like no tomorrow. ;)

     

     

    Oh yeah, it would. I meant the Pascal nature of cards. 

  6. 22 minutes ago, Mr. Fox said:

    I ran 880M SLI for a day or two in the P870DM-G and it worked fine, so I am thinking that the EC crap must not apply to pre-Pascal GPUs. I hope Brother @Prema can strip all that silly crap out of the vBIOS so Pascal doesn't need to do anything except follow orders and do whatever we tell it to. I really don't care for dynamic clocking BS and never have... really stupid when hardware is allowed to make decisions instead of explicitly obeying orders.

    Im not sure he can get rid of it , since it probably needs access to the EC for proper monitoring and "throttling" :P

     

    But @Prema is a magician :D

    I was not referring to Eurocom adding the wire to make an MSI GPU work in a Clevo in a negative way. I'm actually glad they know how to do that and that's great if it works. I was being critical of Clevo about their doing the stupid EC signal thing in the first place.

    Ah, my bad. 

    But the EC thing has been there on the 980's as well. Only thing is that it already comes with the hard mod. 

     

    I'm guessing GPU Boost 3.0 is the culprit here. Since the cards need access to full thermals and system cooling.

  8. 38 minutes ago, Mr. Fox said:

    In that case it is probably what @bloodhawk suggested... meaning some kind of a workaround to the stupid Clevo EC signal thing. I bet it is some kind of jumper wire to let the card power up even though it is not a Clevo GPU. I don't know why they did that, but it sure wasn't a very customer-centric move. Stuff like this is really irksome and extremely naughty.

     

    Easy profits, being the first and only supplier of modded 1070's for the P870DM.

    Ok.. added a EC2-4Gbps reference to the discussion. EC2 is also directly wired to the Southbridge. if x1 2.0 = 373MiB/s, then multiple by 2 to get x1 3.0, then multiple by 4 to get x4 3.0. The result is 2984MiB/s, which is onpar with your 2842Mi/s. So definitely running x4 3.0.

     

    EC2-4Gbps (x1 2.0): 373MiB/s link

     

    That makes sense. The Device to Host actually hovers around 29XX MiB/s  when there are not too many tabs in Chrome or im not doing much. 

     

    Next step is to figure out if its possible to create a powered extension cable/connector.

     

    These speeds made me wonder, if the Proprietary AGA connector is just a fancy looking M.2 port extension. Id actually be willing to buy one and tear it down if someone can get me the service manual with the pin outs.

    @bloodhawk, I moved the discussion content here since it was referencing your implementation, plus I've summarized your hardware as I know it in the opening post. Pictures of the actual hardware and how the PE4C V4.1 connects would bring it to life. A unique eGPU implementation that's for sure.

     

    Yeap, working on that. I dont have a great camera at hand right now. But the One M8 will have to do for now :P

     

    Thank you for moving the posts. Was about to PM you about the same.

    You have "Host Pinned to Device: 2842.01 MiB/s" which would mean it's a x4 3.0 (32Gbps) link as reported by CUDA-Z. That would be faster than TB3 since there is no additional TB3 controller latency to deal with. Rather, it's a direct electrical link to the Intel southbridge.

    Gotcha. Figured as much specially after the jump in scores compared to TB3. 

    Im adding content to a thread over at the other place, that shall not be named. Will update the other thread soon after with the benchmarks.

     

    Can you please link me to an existing/central thread where members talk about tweaking such setups ?

  12. 33 minutes ago, Tech Inferno Fan said:

     

    Pls run CUDA-Z on your eGPU and post the result. We know from

    CUDA-Z Host-to-Device Bandwidth

     

    TB2 -16Gbps: 1258 MiB/s

    TB1-10Gbps: 781MiB/s link

    TB1-8Gbps (x2 2.0): 697MiB/s link

    EC2-4Gbps (x1 2.0): 373MiB/s link

     

    We'll quickly be able to establish it's bandwidth using these reference Thunderbolt results.

     

    Here you go good sir - 

     

    Ill try to do another test over TB3 tomorrow. This is with quite a few USB devices plugged in and the dGPU @ full link speeds.

    The hwinfo64 screenshots confirm the M.2 eGPU port hosting your GTX1080 is running at 8Gbps. It doesn't give the link width. I assume it would be x1 3.0 but GPU-Z would tell us exactly.

    Yep. in GPUz and NvInspector the link does show up as PCIe 3.0 x4 . Im not sure how much accurate that is, specially since the actual limit is 8GT/s 8Gbps).

     

  14. Below we see a 32Gbps-NGFF.M2 and a 32Gbps-TB3 eGPU implementation.  The NGFF.M2 interface directly attaches the video card to the southbridge giving better performance at the cost of inconvenient under keyboard access.  The Thunderbolt controller adding dragging latency  but provided a convenient single cable solution using the external TB3 port.

    Could you please give us a call at  (888) 381-8222 or email us at sales@performace-pcs.com so that way we can get the details of the situation. I do not know who you talked to here but no one here would have any reason to be rude to you or call you homeless and if so we would like to know the details of the situation. Hopefully we can fix this situation and want you to shop here again.

    Thank you for looking into this. 

    I'll try to get in touch with you guys as soon as I'm off from work. 

    At this point since it was a while back , I have pretty much moved on. As I mentioned before, I'm sure it was a one off thing, and probably the person I talked to was having a really bad day (he kinda sounded agitated :S) . That's why I never made big fuss about it. 

    Would love to give you guys another chance, now that @Mr. Fox mentioned that he has had a great experience with you guys.

    Hmm. Maybe the owner of the place would like to look into this. I think I will ping them because employees that do not do right by customers need to be held accountable for bad behavior. It doesn't take more than a couple of times to hurt a small business.

     

    Sure. It was quite a few months back though. Ill message you the details , later tonight.
