 System

Lenovo W530 with I7-3940XM 32GB

Win10 + INF mod to get GTX1080Ti working

BPlus PE4C V3.0 Expresscard

 

benchmark scores

 

GTX 1080Ti GTX 1080 GTX 1060 6G

 

 

 

 

 

 


To use 1080 Ti we need newer than 379.78. As we know to install newist driver we can use 361.81 trick. But 361.81 dosn't support 1080 Ti.

 

My system is 

 

Lenvo x23 and w530, 1080 Ti, BPlus PE4C v3.0 with Expresscard

 

I tried...

 

1. Use 361.81 trick with 1060 and replease to 1080 Ti -> error 43

 

2. 379.78 + 1080 Ti (with DSDT) -> Error 12 (with DSDT error 43)

 

3. Nando4's 1.35 + 379.78 +1080 Ti (with DSDT) -> Error 12 (with DSDT error 43)

 

Anyone have any idea?

You are treading in unchartered waters here. The GTX1080Ti is new so using older drivers to work around error 43 would require INF modding and so is tricky. As an aside, a expresscard Lenovo X220 works with a GTX1080 using 373.06 drivers:

I also have 1080 and it work perfect with 361.81 trick. I'll try INF modification in this weekend. (ref  http://forums.guru3d.com/showthread.php?t=377158

INF modification works for 1080 Ti

Please find modified nv_dispi.inf for 368.81.

 

Steps

1. Enter testing mode.  (to install unsigned/modified device driver)

   (Run as administrator) bcdedit /set testsigning on 

2. (If you did not install any nvidia driver skip 2. otherwise ) Uninstall driver with DDU (Display Driver Uninstaller)

3. reboot  

4. Unzip 368.81 driver and replacement nv_dispi.inf ("unziped folder"/Display.Driver/nv_dispi.inf)

5. Do 368.81 trick ( https://egpu.io/forums/expresscard-mpcie-m-2-adapters/nvidia-is-killing-off-mpciengff-m2-egpus-error-43-with-372-90/paged/2/#post-4453 )

6. Leave testing mode.

   (Run as administrator) bcdedit /set testsigning off 

 and reboot

 

Toubleshooting 

1. After step 3 , ACPI_BIOS_ERROR windows bootop BSOD.

Set switch 2 to 2 or 3 ( it's mean CLKRUN delay 11.97s or 16.9s) and after step 6 back to 1.

2. Tobe added...

 

 

 

My  system is

@lovehis, love your work. I've added your W530 system details and benchmark results in the opening post to make this an implementation guide. Your system is now at the top of the 4Gbps class leaderboard: https://egpu.io/external-gpu-implementations-table/?table_filter=%224Gbps%22#search

Feel free to add pictures to bring it to life.

This worked for me too, and on a w541! Thank you lovehis for figuring it out. You wouldn't happen to know how to route it through the internal display (still via expresscard), would you?

Hi lovehis, 

eGPU and computer gaming noob here wanting to ask if/how the expresscard setup affects gaming options. Is there a bottleneck? 

Someone on reddit said that Expresscard 2.0 eGPU setups generally cut card performance by 70-80%... not sure how they got that number. 

I also have a Lenovo W53o and am deciding if I should try an eGPU set up. I was thinking of using a geforce gtx 1060 6gb (along with my laptop's intel i7 3270QM, 16GB). 

Hope I'm not asking a dumb question or something. I didn't really know where to ask about bottlenecks on expresscard setups, but i'd appreciate any references to other information too. Thank you! 

Happy Holidays,

New to the forum myself but been reading non-stop for the last 2 days, so I will try to answer from what I gathered.

If you are using the external GPU output, than its a ~20-30% Performance cut.
If you are using the built-in display, the bandwidth bets cut in half(2 way traffic) and will be probably a 60-70% performance cut.

You also have to pay attention, to have a Gen2 setup, as the gen1 is again a big performance cut.
