Setup 1.30 Discussion

Awesome. Your entire setup is sexy :) Even your desk :P.

Its a shame thunderbolt solution cost so much, it really shouldn't.

Can you test 3dmark11 3DMark 11 - DirectX 11 video card benchmark from Futuremark, you seem to have provided 3dmark (the cross platform one) instead.

And if you have bf3, bf4. Bf3 is much more bandwidth bound than bf4.

And is that a QX2710 screen?

Would you mind posting your Cuda-Z Performance Tab results? I'm curious what speeds you are getting. btw, great work, looks amazing and super clean.... I hope to have something as clean looking as yours

Also it will ba intrestind to see test games like Crisys 3, smth on Unreal engine 3 or later version.

This is very interesting... Both the Dell XPS l502x and 702x have the slot needed to harbor the pe4h adapter. So what would you think the fastest card you could theoretically run?

I have several clients that do design work that this will come in very handy for. I am a bootcamp "master" so to speak and I am going to play with this setup. Sounds really good.

I recently got the EXP GDC, and it works generally fine.

My laptop is lenovo w520 (i7 2720qm + quadro 1000m), PSU is corsair cx430, and EVGA GTX 750Ti SC for graphics.

There was a day that I constantly have an error about driver stops working. It seems solved after I re-install the driver. I am not sure if it's because I was using the beta version of the driver or what.

Hello,

I just paid via paypal. When will I get the download link?

As far as I know, the Macbook Air does not have an expresscard slot and the mpcie implementation is also a nogo. And also afaik there is no thunderbolt version of the EXP GDC.

How are you planning to connect the external gpu?

Update: Seems like my GF has a 2011 Macbook Air with an Intel 3000, so she can't really make use of it. I'll have to wait till I can test elsewhere or when I plan to buy any new macbook airs that might be announced at WWDC in June (rumors of a Macbook Air Retina).

Also to "paper-clip" Green (PS-on) wire with the Black (Ground) is not so elegant solution.

Much better is to use SSR (solid-state-relay) to control Green-Black connection and power the relay from USB, so when the cable is plugged, the SLAVE power supply switches ON automatically and when the MASTER computer is turned OFF ( or cable disconnected ) the SLAVE power will go instantly OFF.

Could you give some more details on how to make this work?

If you read the instructions from the Thundertek, it says it powers on itself when it is attached to a thunderbolt port. Could this be used to power on the ATX PSU?

If you can find a point of the Thundertek that changes from high-Z (open circuit) to ground when plugged into the THunderbolt port, then can route that point to the active-LOW green wire on the ATX PSU. Upon detecting the GND transition, the ATX PSU will power on. Alternatively you can just make a manual switch between the black (GND) and green wire to switch on power : How to power up an ATX Power Supply without a PC!

Or if your ATX PSU already has a switch, just jumper those permanently using a paperclip:

If you want me to test anything, let me know!

If you happen to have GTX670 available I'd love to see some benchmarks over the Thunderbolt link in comparison to my 1x setup!

GTX660 isn't too far away from a GTX670. See x1.2Opt versus x2 2.0 Thunderbolt benchmarks at http://forum.techinferno.com/diy-e-gpu-projects/3062-%5Bguide%5D-2012-13-mbp-gtx660ti-hd7870%40x2-2-th05.html#post42483 and commentary. My HP 2570P with x1.2Opt link and i7-quad is going to stay until there's a better choice of Thunderbolt notebooks: http://forum.techinferno.com/diy-e-gpu-projects/4109-egpu-candidate-system-list.html#post57159

Unfortunately I am not sure how to figure out where such a point would be on the board.

But a picture of it got posted here, maybe some of the unused connectors can be used for this?

A picture isn't going to tell me if there is a point that switches from high-Z to ground when you plug the THunderbolt cable in. It's a low agenda item. Just use an ATX PSU with a power switch on the back and paperclip the ATX plug green-black as shown in my previous reply. Then take 1 second to switch it on before plugging in the Thunderbolt cable. There done, now you have power. Then deal with other issues that might be problematic : error 12/43, TOLUD, UEFI/MBR mode, PCI Reset Delay and any performance issues. Once it's all working can use a multimeter to find the GND point to give (now) working eGPU implementation it's final touch.

Didn't this guy basically have no trouble with any of this?

Sorry for perhaps being clueless, but I'm quite new with eGPUs, but am considering getting a thundertek.

And what problem are you referring to? You asked how to switch on power when plugging in a THunderbolt cable and two solutions were provide, with the 10second solution being paperclip the green and black wire and use the ATX PSU switch. If you had the bits already and were attaching it then would have spent much less time implementing it than writing the 3 posts analysing this non-problem.

Sorry for not making this clear. I was talking about the problems you brought up such as error 12/43, TOLUD, UEFI/MBR mode, PCI Reset Delay and performance.
