Northern-Loop

When my gtx 670 steps up from 1.1 to 2.0 the driver crashes and I lose all performance. It's fine running at 1.1 all day but only maxes out around 30FPS

Can someone let me know the correct procedure for using the DIY setup?

Interestingly, I have this problem with my 8600GT (test card) in Windows 8 64 bit, but not Windows 7 64 bit,

As far as I can tell it's caused by Windows still seeing the dGPU and thus Nvidia control panel is getting confused.

Happens in Windows 7 and 8 for me.

Install the patch for Setup 1.x to get Series-7 chipset support. It's available from http://forum.techinferno.com/diy-e-gpu-projects/2123-diy-egpu-setup-1-x.html#post27337 .

You could only disable the dGPU if it's not the primary video device. The iGPU would need to be the primary.

For the iGPU to be the primary video device, you must have a M6700 *without* the IPS LCD option. So then if you have the TN panel then the second issue is the Dell bios must not see the eGPU on bootup or else the iGPU is disabled and the eGPU becomes the primary video device. To avoid that the EC2C PE4L end needs to hotplugged after boot or set the PCI Reset Delay (PERST#, SW1=6.9s) so the bios doesn't see the eGPU.

You can check whether you have an iGPU by booting without the eGPU connected and seeing what devices are listed in Device Manager -> Display Adapters. You'll have a Intel HD4000 if the iGPU is active.

Since I upgraded to the series 7 I can't get the solution to boot. Just hangs in the Windows 8 logo

Thanks, I didn't see the update. Will install later.

Yeah I have the M6700 with the LCD panel. Without your setup my laptop will see the GTX 670 and partly use it for CUDA and OpenGL. I'm just not getting very good performance out of it.

I'm using the ViDock which seems to work okay.

With the eGPU plugged in I have 3 working GPUs in Windows. Can't take advantage of optimus though as the control panel won't open. Complains about no Nvidia GPU

Disable optimus in the bios and I can use dGPU and eGPU in the Nvidia control panel but it uses the dGPU for the main tasks.

The reason I have purchased the eGPU is for the CUDA rendering and if I get some higher FPS for games it's a bonus.

Hi UncleJoe,

Is it possible you could assist me as I have a Dell M6700 and struggling to fix a couple of issues?

1. In the Intel.txt file there is no Series 7 chipset settings so I can't seem to run at the full 5gig?

2. If I try the standard disable dGPU my system hangs?

Do I need the Setup 1x to enable optimus? My GTX670 is enabled and working but I can't get into the Nvidia control panel because it says there is no Nvidia GPUs installed.

I have 2, the disabled dGPU Quadro 3000m and my eGPU GTX670

Can anyone help on this? I only have 14 days with the GPU before I have to send it back for a refund if it doesnt work.

At the moment I can not enable optimus with the dGPU and eGPU in the system.

I ran into this problem sort of, but was able to use the output of the egpu as an extended desktop card.

when you try to set resolution and monitor setup, does windows show more than 1 monitor?

Only 1 for me and the GPU it is using is the Intel 4000

Bump I also have this problem. The my EGPU unplugged Nvidia Optimus works fine. I have tried disabling my dGPU but still says the same error message.

Hello,

1x is the best you can get with an EC2 Slot. So you best go with [email protected] and try to enable optimus, since you have a GTX 670.

X2 and higher are only possible with more than one ECSlot or mpie slot or a combination of both. And I think they wont work at 2.0 speed.

Do you have the Nvidia GTX 670 driver with the optimus enabled? - I have tried to amend the NVAM.INF file but the Nvidia control panel still complains that there is no Nvidia GPU enabled.

Ah right thanks,

I have 3 GPUs installed,

Intel 4000

Quadro k3000M

GTX 670

The Nvidia control panel says I dont have a Nvidia GPU installed when the GTX is installed. If I disable the Intel 4000 I can get in there with the 2 Nvidia GPUs but I dont have optimus setting. Not sure how to get it working?

Hello, I have a Dell M6700 with a EC 2 Slot and I have purchased a Vidock to use with GTX 670 but I can only seem to run it at 1x @ 1.1/2.0? Is the 1x the best I can hope for? The performance isn't the best using that.

1 other thing if I enable the Intel 4000 GPU the Nvidia control panel complains that I don't have a Nvidia GPU installed? dGPU is Quadro k3000M
