  1. Tnx, I did a clean windows 8.1 install yesterday. I did install the drivers in the way you mentiond above. But it will still give an BSOD when starting up Lumion. On the other side, the program did work for the dGPU again untill i did some tweaking in the Nvidia control panel. Maybe some other suggestions? Tnx!
  2. @jacobsson Yes i did indeed. 340.52 were the drivers I had on my setup before i started with the egpu. Because i cant run lumion on my gt750m anymore after tweaking the registers TDR i'm thinking of doing a clean install of windows all over again. (I did install lumion a few times) Do you have any tips in witch order i have to install windows and (video) drivers? Do i need to install the drivers with the egpu connected for exemple? Tnx!
  3. @krazyazy So you stopped using the Akitio Box? Im using the following riser cable: Riser Card Extention kabel PCI-E 16x naar 16x (+ Molex) 15cm - RC-16X-16X-15CM - Yorcom.nl @Tech Inferno Fan In addition to my previous post: I did a check with the GTX660ti in my desktop setup. It's running on the default manufacturer settings of 1059/1502mhz. When using the specific problematic program (Lumion) I find the GPU Load on 99%. Could tis be a problem for an eGPU setup?
  4. Hi Nando4, tnx for the reply! So i'm back to the modular PSU. I've tested the card at it's default clock speeds (GPU Clock 1059/Memory clock 1502mhz) And on the reference clocks from Nvidia (GPU Clock 915/Memory clock 1502mhz) Still no luck. It always fails at the moment of starting that 3D intensive program. This card is from my desktop pc. It runs without issues. Maybe some other troubleshooting? Is there some additional info i could give you guys? Thanks a lot!
  5. @jacobsson That's no problem, i'm glad your willing to help! First i've used my modular 620W PSU with this specs: After that I tried this one, a non-modular ATX 400W PSU with the following specs: I'm using a Macbook Pro late 2013 with a igpu iris pro 5200 and a dgpu GT750M. The igpu is not visible in windows due to bad gmux drivers (apple didn't write any as far as i know). So i'm planning to use my eGPU on an external display.
  6. Ah ok, tnx for explaining that to me .. Yes, I did clean my drivers with DDU before installing the new ones. I also checked my register with ccleaner before installing new drivers. I did some testing with the TDR manipulator. But it didn't solve the problem. I tested if the TdrDdiDelay was the problem by setting it to 30 sec. I also tested if setting the TdrDelay to 30 sec. would solve the problem. When I start the program (Lumion, a 3D modelling tool for generating architectual render in a 3D world) the external screen just goes black. Before tweaking the TDR delays it generated a BSOD in just a few seconds. After tweaking the TdrDdiDelay and the TdrDelay it keeps showing me the desktop on my internal display where I can use my mouse, but can't click on anything. After 30 seconds it also generates a BSOD. So i decided to check if disabling the TDR function would do anything, but, as expected, it don't generate a BSOD but just freezes. The same Video_TDR_Failure happend when i plug out the thunderbolt cable. Could it be that the GPU just has a timeout and disconnects from the tunderbolt port witch leads to the BSOD error? Some suggestions on this subject?
  7. @jacobsson Thanks for the quick reply! I swiched my power supply to an ATX PSU. Didn't get what you ment by DA-2, but i think you ment the other PSU (your old one)? In my case it didn't work out.. Some other suggestions? Tnx anyway!
  8. Hi there guys! This is my first post here. So if i'm doing something wrong, please correct me! .. I've read this thread with much interest and because of the good results I've bought a Akitio Thunder2 PCIe Box myself. I'm planning to use it in the following setup: MBPr late 2013 with nVidea 750m dGPU. ASUS GTX660Ti Direct CUII Top Coolermaster 620W (had lying around) Thus far I've got it running on windows 8.1 EFI install. It detects the card, and with an external monitor it gives me an extended desktop. [ATTACH=CONFIG]12942[/ATTACH] [ATTACH=CONFIG]12943[/ATTACH] [ATTACH=CONFIG]12944[/ATTACH] [ATTACH=CONFIG]12945[/ATTACH] So i was pretty happy thus far. But here's the problem. It generates BSOD's with the following error: [ATTACH=CONFIG]12941[/ATTACH] On Sun 26-10-2014 11:50:15 GMT your computer crashed crash dump file: C:\Windows\Minidump\102614-11703-01.dmp This was probably caused by the following module: nvlddmkm.sys (nvlddmkm+0x91DC84) Bugcheck code: 0x116 (0xFFFFE001713A84D0, 0xFFFFF801C7FD6C84, 0xFFFFFFFFC000009A, 0x4) Error: VIDEO_TDR_ERROR file path: C:\Windows\system32\drivers\nvlddmkm.sys product: NVIDIA Windows Kernel Mode Driver, Version 344.48 company: NVIDIA Corporation description: NVIDIA Windows Kernel Mode Driver, Version 344.48 Bug check description: This indicates that an attempt to reset the display driver and recover from a timeout failed. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 344.48 , NVIDIA Corporation). Google query: NVIDIA Corporation VIDEO_TDR_ERROR The following things i've tried thus far: - remove old nvidea drivers with driver sweeper and clean the register with ccleaner. - installed various driver versions (314.22 to 344.48). I thought that it could be some power issue also (because of the single wired molex at the PCI riser it could get insufficient power?). But haven't had the chance to check that. Maybe someone with the same problem could confirm it? Some other advises would be great also! I'm a little stuck here... Thanks in advance! Jakob.
