HELP! GTX650TI with error 43

I'm currently doing a eGPU project on my VPCSA25EC(I5 2520m, 2x4G DDR3, HM67 chipset,Intel HD3000 + ATI HD6630m) with a GTX650TI attached to it.

From my previos experience about mounting a GTS450 into this laptop, I create a dump for the graphic card, and load it before compaction(4GB), and I disabled the HD6630m. Without any modification to windows 7, I install the latest official driver (350.xx) and It work, I'm able to connect a external vga screen to GST450, and it works without any problem.

But the tragedy starts when I trying to do the same thing to GTX650TI. I setup the driver for it, after restart, the system stucks in the welcome screen for a while, and I end up with Error 43. By inspecting the system log, I found that one of the nvidia driver was unable to start.

I tried to boot into win7 first and then sleep, then do a hot-plug and resume. The error 43 does gone, but I'm can not open the Nvidia controll center.

Does anyone can come up with any ideas about this problem?

I have spent over 40 hours on the previous eGPU project and at least 6 hour on the current one QAQ:bananalama:

I recorded the resource usage of GTX650TI and GTS450, in case it's useful:

GTS450: 128MB + 64MB + 32MB

GTX650TI: 128MB + 32MB + 16MB

I got those result from a desktop platform, with the graphic card on the second pcie slot(pcie1x)

please help QAQ

The problem has been solve.

The problem was caused by my self-made hardware, it was using a 50cm FFC to transfer the PCIE signal, I guess the lose is too high to make it works properly, I replaced it with a 10cm FFC and get rid of this problem /w\

Later I'll post a thread about my full setup /w\
