12 g ddr3 ram
intel i7 Q720 @1.6ghz
discreet card: Nvidia Quadro Fx 880M
egpu setup: GTx 960 card hooked up via exp-gdc v8 dock via pci express card
Using dell 220w psu (12v, 18Amp)
Using an external monitor hooked to 960 via hdmi
Drivers successfully installed, device manager shows GTX 960 and shows it functioning properly. However, no external monitor can be detected. Aditionally, when installing the 960 drivers, it broke the 880M (shows up as error code 43 in device manager iirc). So currently I'm stuck with crappy display on the internal monitor (internal graphics? even though I don't have intel integrated graphics..) and no external monitor detected.
I read in the FAQ section that trying to get a dgpu and egpu from nvidia to work is about getting them to run on the same drivers, but it was not clear at all about how to go about doing that. Plus the cards are so far apart in age I'm not sure how to even begin to go about trying to find a drive that will run both.
What I have done so far:
Disabled pci power managment, this allowed the egpu to be sucessfully detected. Showed up in device manager as "generic vga device" or something like that. Downloaded and installed appropriate nvidia drivers for 960, restarted computer. Computer running on crappy internal(?) graphics card (cant even display full screen resolution) , error for dgpu in device manager (error only goes away after uninstalling 960 drivers and reinstalling dgpu drivers), 960 shown as working fine. Disabled dgpu in device manager (I don't have the option to in the bios for some strange reason, screen shot attached), restarted. Upon restart device manager shows 960 working fine, however, no external monitor detected and computer internal dsiplay still running on crappy internal(?) graphics card (cant even display full screen resolution).
Any help would be much appreciated. I feel like I should be pretty close since the egpu was detected and is shown as running ok in the device manager...
I bought the EXP GDC v8.0 to use with my laptops:
Alienware M17x R2 (no iGPU)
i7 920xm GTX 680M 16GB DDR3 RAM ExpressCard x1 Windows 7 x64 Ultimate
Alienware M14x R2 (iGPU)
i7 3840qm GT 650M 16GB DDR3 RAM mPCIe x2(?) Windows 7 x64 Ultimate
I am using:
ZOTAC GTX 970 300w PSU DIY eGPU Setup 1.30
My problem is that Windows does not detect anything on either setup. No drivers are ever installed for a "Standard VGA Adapter", and I always check Device Manager. I have tried everything on the TechInferno webpage here, but nothing happens once in Windows. I have entered into the DIY eGPU Setup (menu option) several times trying what it recommends to get the graphics card to be seen, and messed around a bit with the settings, but none of that works either. Sometimes certain options will cause the laptop to hang and force me to reboot.
The ExpressCard slot and mPCIe slots of my laptops do work, I regularly use the ExpressCard with a USB 3.0 card, and I normally have a WLAN and a M.SATA SSD drive in the mCPIe slots (both I have extensively tried with the EXP GDC adapter). The graphics card only boots up (with fans on full blast) once the PSU is plugged in after the BIOS has loaded. If I have it connected from a cold boot, the card will attempt to turn on with slow fans and then turn off on either laptop. The graphics card is lightweight and fully inserted into the EXP GDC adapter. There is no switch on the PSU, so once everything is plugged in (and the laptop is on), it just goes.
I thought it would at least work on the M17x R2 since there is an Amazon review comment stating that it does. The only other thing I can mention is that the GTX 680M was never officially meant for the M17x R2, so I have to hack the NVIDIA display drivers to get NVIDIA driver support. I don't think this has anything to do with the eGPU detection though (especially since the DIY eGPU Setup dose see the GTX 680M)... And, if it helps, I do have a Dell 220w power brick I can use instead.
If anyone has any suggestions I can try, I will, as I really want this old laptop to run at its best before I move on.
Thanks in advance!
