Order: start - f8 - plug turned on eGPU - later states of installation:

Notice that before installation nVidia drivers, GPU-Z sees eGPU on PCI-E 3.0 ;)

results 3dm06 and 3dm11.

External, power: balanced, Gen2. Temperatures during test in room (not on the sun) where was ... 30-31C.

Hello, i am currently running a 8460p with Windows 7 Sp1 X64 16GB RAM and with a GTX650 1GB i do get Error 12... do i need a dsdt override with this laptop? It seems that you did nothing special....

GTX650, GTXT750 and GTX9xx require a contiguous 256MB PCIe config space block that the 8460P BIOS allocation cannot provide without a DSDT override. @bjorm used a GTX760 which requires a lesser 128MB contiguous space (+ a little more.. 32 or 64MB that can be in another block). A GTX760 can fit in the remaining free 32-bit PCIe config space as set by the BIOS. So could a GTX660/670/680/770/780. It's just those aforementioned cards that require a DSDT override, as too do AMD ones.

Thank you Tech Inferno Fan for that clarification, i think i am going to buy a GTX670 to get some gaming and ditch my free GTX650.

I tried the dstd override but the asl file compilation threw up errors like crazy, 140+ errors and i couldn't get it to run...

is it possible to take the needed files from another 8460p with windows 7? maybe someone had success before me with that :-P

Ok today i got my eGPU working!!

 

8460p Windows 7 x64 DSTD override

16GB (2x8GB) RAM

 

GTX 660 2GB from Gainward:

only quirk i found is that it laggs like crazy after a game, if i run cs:go and then go back to the desktop i can not surf with chrome as it laggs while scrolling. Is the PCI-E Link right?

I do run a PE4L 2.1b which is soldered to the express card.. my slot is set to Gen 2 instead of Gen 1 if that helps :-(

 

Hot Un-plug works, but needs a rebot to get it working again.

Try setting Gen1 in the bios or using Setup 1.30 to see if it fixes the lagging. We've also had one user note that the NVidia power states were not switching correctly causing flakey behaviour. Something that was fixed by install NVidia Powermizer. If the lag is still present and obvious when gaming then it may point to crosstalk along the eGPU link that happens when the cabling has frayed.
