I have successfully installed gtx 660 ti on Windows 10 with optimus enabled(not sure though) benchmark using External LCD

There is an existing W540 eGPU implementation using a PE4L 2.1b so the expresscard can be made to function. That was with a AMD and NVidia card: http://forum.techinferno.com/implementation-guides-pc/7388-15-lenovo-w540-r9_290x-gtx780ti%4010gbps-4gbps-sonnet-ee-se2-pe4l-2-1b-%5Bgothic860%5D.html#post101232

May I suggest you revert to http://forum.techinferno.com/diy-e-gpu-projects/2129-diy-egpu-troubleshooting-faq.html for ideas on how to get the eGPU detected.

Strange indeed. I did have one user report a faulty HDMI cable that caused poor performance on his external LCD. Maybe try that? We'd otherwise expect the external LCD to outperform the internal LCD when ran at the same resolution and color depth since display traffic is going straight out. Internal LCD mode via Optimus has a bandwidth penalty for display traffic via the notebook hence why it's expected to have poorer performance.

Also, do you see a gaming benchmark like say Resident Evil 5 give faster performance on the internal LCD? If not, then might be something unique to MSI Kombuster.

I have also tried unigine benchmark tool, also giving the same results... but on my other laptop, 2540P, external monitor is faster than external.

Strange, now i'll try to install windows 10 with new nvidia driver, 358.91, will see the results are still the same.

thanks!

Hi All,

Im having a small problem with my build.

6450B i5 M520

EXP GDC BEAST

GTX 660 TI Jetstream

8GB RAM

FPS is much faster on my internal LCD than my external

any idea why?

I actually didn't have to use Setup1.3, i just plug and play using express card slot

any help will be much appreciated

Hi All,

Can anyone suggest if which will be better for Adobe After Effects. HP2540P + GTX 560ti + exp gdc beast or HP2540 + GTX 570 + exp gdc beast?

TIA
