trollinteemo Posted October 4, 2014 Share Posted October 4, 2014 Hey,I sent this in an email to nando and jacobsson, yet I got no response so I thought I would see what the general users think of it. I feel that this forum is a bit messy and hard to read for new users, so I devised what I think is a better way to organize the forum.http://pastebin.com/eJ4DT8hE Link to comment Share on other sites More sharing options...
Lind.LHeart Posted October 5, 2014 Share Posted October 5, 2014 when you switch to internal screen,you put the prefered grapchics processor to nvidia in the nvidia control panel?thanks for the reply. i cant seem to even have it to run in internal screen... the computer says that it seems to be working properly but it doesnt seem to actually recognise it... is it because i dont have the setup1.x and all?

Tech Inferno Fan Posted October 5, 2014 Author Share Posted October 5, 2014 Finally got the benchmarks If you include your pics at http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-383.html#post108090 , a brief writeup of the steps you did and add 3dmark06 and 3dmark11/13 performance runs at default resolutions then I can add your implementations to http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html#dx11 .

Tech Inferno Fan Posted October 5, 2014 Author Share Posted October 5, 2014 Yes, I have got it working on the internal screen, I have also managed to working on the external screen, but not without problems. I enable Gen2 port in the setup 1.30, and when I get to the welcome screen, this is where the problem comes in. The display switch back and forth between internal and external screens, with the "an error when running Nvidia graphics driver" pop up appear. It does that repeatedly until BSOD shows up. How did you make it work on your laptop? Please help me out. @coyote, I have had extensive comms with useafo about why his GTX660 doesn't support Gen2 reliably yet his GTX550Ti does. The conclusion being there is likely a mimatched impedance on the GTX660 preventing Gen2 operation with the possibility that another vendor's card OR use of a EXP GDC instead of PE4C V2.0 will correct that issue. 1 Link to comment Share on other sites More sharing options...
Videoapan Posted October 5, 2014 Share Posted October 5, 2014 regarding more tan 2gb issue you can do a dsdt override.NOW to work with the internal screen you need to have an Intel hd integrated ghrapics to active optimus.i sugeest try sell your laptop and buy one at least with second generation icore.Thank you for the reply! So it is as I suspected/feared.. Unfortunately I couldn't find this information earlier but at least now I own an eGPU :-) Is it Optimus that require an Intel iGPU so that it can't be tricked? I was hoping that it would work with any iGPU but it doesn't seem to be like that. Buying a new laptop isn't a priority right now so I'll just have to play games on my stationary PC and not while on the go.I'll check the DSDT override if I get another incentive to try the eGPU with my current laptop.

It is indeed odd that his GTX550Ti worked well with the same configuration whilst the GTX660 didn't. If I were to speculate, I'd say to test the GTX550Ti with the PE4C, see if it works, then if it does, proceed to get another GPU. @useafo, as Tech Inferno Fan explained, it looks to me like a hardware issue from your GTX660. Return your GPU saying it doesn't work and try to get another one. Good luck.@Lind.LHeart did you do the DSDT override? Link to comment Share on other sites More sharing options...
dan Posted October 5, 2014 Share Posted October 5, 2014 Finally got the benchmarks 3DMark 2006 @ 1920x1080 3DMark 11 @ 1920x1080 . thanks.are you run 3dmark 06 with x1.2 optimus?because it seems that you have a low score. i sugest you a few things: make sure you have dgpu disable in order to ensure x1.2 optimus acceleration check that during benchmark your pci-e link it pops-up with x1.2 bandwith.by using EVGAprecisionx with Rivatuner activated ,combined with HWMonitor you could see in real time on the screen the behavior of each component including pci-e link put the system on máximum performance in the energy options or use throtllestop to increase the performance of the CPU even with an i7 like yours i think you have to have an increase by 25-30% of the actual results.

davide445 Posted October 5, 2014 Share Posted October 5, 2014 Just an update atout my flickering problem, if can be useful for others.In my case I did see horizontal strings all over the screen when the eGPU come under load, from any kind of app (browser, video editor, 3D engines). Strings disappear immediately after the GPU work finished.Reading on the net appear to be a common problem for HD 7xxx series, without a single solution.Can come from Catalyst driver version, problem from voltage management, bad card, OC, connection cable quality, vsync, bad VRAM, bad power supply.After testing: GPU underclocking, RAM underclocking, voltage increase, voltage decrease, forcing vsync, forcing display refresh, cable connection strengthen, disabling any GPU image enhancement, I did maybe discovered the problem.I attached as a monitor my led TV using HDMI cable instead of the DVD-I-->VGA adapter I used on the old monitor.No flickering at all, so I will buy a HDMI or DP or DVI-D to VGA adapter and will see if will work on my display in the same way.
