15" Lenovo L520 + GTX750Ti@4Gbps+c-EC2 (PE4C 3.0) + Win10 [vintagely]


Recommended Posts

Hi everyone and thanks for this wonderful forum.


I'm about to start this eGPU project and would like to know if anyone can provide me tips or tricks to overcome all the issues i'll be facing on this project.



Basically the general idea is:


I will use a Lenovo L520 of mine with the following specs:


i5 2540M 2.6 Ghz (dual core + HT Sandy Bridge)

Intel HD 3000 (required by Nvidia Optimus driver to use internal monitor)

8 GB RAM (i will be facing the error 12 issue most likely but i plan to overcome this issue with Tech Inferno Fan Setup 1.30 - DSDT override seems to not work here)

Windows 10 (will be this OS an issue for me?)

ExpressCard 2.0 slot available


Gear i plan to use:


Bplus PE4C-EC060A V3.0 with ExpressCard adapter

Nvidia GeForce GTX 750Ti (no external power required) - max drain 60w

Dell D220P-01 AC adapter in lieu of ATX PSU


My questions:


1) Is my project generally doable?

2) Will Nvidia Optimus work on my internal LCD with this Bplus adapter?

3) What would be the performance loss due to express card / nvidia optimus combo bottleneck?


Thanks in advance for any reply.
