Hello, I have a DeLL Latitude E6440 and use PE4C 3.0 expresscard + RX 580. One problem I tried to use a GTX 1060 6gb and 3x GTX 970 (zotac, gigabyte, msi), however all NVIDIA cards are quite unstable in gen 2, causing BSOD in less than 2 min while playing. AMD boards are 100% stable in gen 2, no errors or BSOD. Could someone tell me if there is a possibility to solve such a problem? Because I'm wanting to replace my RX 580 with a GTX 1070ti.
Thanks.

Consider testing a different brand Nvidia video card as small impedance differences affect Gen2 reliability. Or better yet, consider a mPCIe eGPU implementation since it directly attached to the systemboard.  By contrast the E6440's EC slot adds extract connectors off the systemboard which also adds impedance.

Ok, I'm going to buy other Nvidia video cards.
I'll also be buying an MPCIE egpu.
Thanks for their tips.
