2011 15" Dell XPS L502x (GT540M) [2nd,4C,Q] + GTX 1060 @ 4Gbps-mPCIe2 (EXP GDC 8.4) + Win7 [TheGermanGuy]
ALSO MADE AN IMPLEMENATION VIDEO-GUIDE:
This is getting very inteersting for all Dell XPS15 L502x Owners.
In general this is a very good Laptop for Using EGPU, because it already has DGPU und IGPU so you can use Optimus etc. etc.
Normally you use the WIFI Pci-E Slot and you read everywhere that the WWAN /TV Slot cannot be instrumentalised to use with EGPU.
Thats... WRONG! On this Laptop you can use it and leave your WIFI where it is! Also i run it on 382.53 Drivers perfectly!
The latest drivers don't work with chrome and firefox, others had success even with the newest drivers and a GTX1060 using
the "russian" method (see below)
I found a way to use the WWAN /TV Slot on my L502x. I can now run the EXP GDC 8.0 and my Wifi PCI-E Module at the same time!
I get 6700 Points in firestrike WITH THE INTERNAL Full HD DISPLAY! (ca. 8700 with External FULL HD Display)
L502x EGPU Instructions:
1. Uninstall all Nvidia Drivers with "DISPLAY DRIVER UNINSTALLER" in Windows "Safe mode."
4. Power Off the L502x AND get the Battery out, and get grounded! + Mount the EXP GDC Cable into the WWAN slot + Switch the "ATX Power" Switch to always ON
5. Start PC without (!!) The HDMI plugged in the EXP (but the mini pci-e in the WWAN port)
6. Boot into Setup 1.35 go "MENU BASED". Then:
- plug in the HDMI cable in THE BEAST and Press "F5". The eGPU should get detected!
- select PCIe Ports->Gen2 to activate Gen2 link speed for the eGPU (Nvidia). Hit F3 key to save.
- select PCI Compaction->endpoint=56.25GB
- select PCI Compaction->Run->eGPU
- select Video cards->dGPU[off] to deactivate the dGPU. Hit F3 key to save.
- select startup.bat->test run
- select Chainloader->test run -> boot into Windows
7. Now you should see a VGA ADAPTER in the device manager
RESTART AND YOUR GOOD TO GO! SImple as that... works only on some Laptops because sometimes the WWAN is just USB 3.0 internally...
Now it sound so easy but i figured and figured till i got there, because first i try to get the WIFI Pci-E hotswapping etc.. with the WWAN its so much easier!!!
A BIG BIG THANKS TO NANDO WHO HELPED ME LIVE AS I WENT THROUGH THE PROCESS.
The next things i will do:
1. Install a HDMI Port on my Laptop using a female to female adapter, shorten the cable and test out different same build quality HDMI male to male cables from amazon and figure out if they work in conjunction with the female to female adapter.
My goal: To plugg the EGPU just like any other device on the installed HDMI Port so that it is as easy to use as any other device... I keep you all updated. More Pics to come soon!
That's an impressive guide for L502x and other mPCIe eGPU implementations. Thank you for taking the time in creating it.
Just wanted to chime in with my implementation. I also have the L502x with GT540m, but couldn't get it going using the e-mail instructions. I then followed this guide, but didn't want to mess around with extracting and editing the DSDT as it looked like it would take many hours of tinkering with the code to get it working.
So, I did all the steps above, but simply didn't replace the DSDT at all and it worked just fine for me, from the WWAN port. This is for a GTX750 as the eGPU, which has no on-board power connector, using a variety of drivers.
Hope others find TheGermanGuy's guide useful!
I have dell l502X with following configuration:
1. Processor i7-2630QM
2. 8GB RAM
Also does the laptop use the internal GPU when external GPU is not detected?
Note: I do not want to use it in linux just want it to work on windows just want to know if any step changes because of dual boot.
Thank you very much @thegermanguy for the step by step simple and detailed post. Only problem is that if I turn on my laptop and egpu adapter at the same time, my laptop doesn't start and gives a blank/black display. So, I'm always required to turn ON the laptop first without turning ON the egpu, then after it passes BIOS, halt the timer at windows boot menu selection for OS/eGPU setup, power ON the eGPU adapter then connect the hdmi cable to the eGPU adapter and then continue with the starup.bat default option (option2) in eGPU setup. Please tell me if there is a workaround for this. I also had to disable the windows update as it keeps installing the inbuilt nvidia driver when I boot my laptop without eGPU adapter for normal/non-gaming use.
I did not do the jumper trick on the psu. Just set the ATX Power switch to ON on egpu beast adapter. Downloaded and used the dsdt-modifed.aml file directly from dsdt repository for my system model to fix error 12 and installed the Nvidia error 43 fixer zip file directly.
My setup: Dell XPS L502X, i5 2410, 6GB RAM, dgpu: Nvidia GT 540M, OS: Windows 10 Pro, eGPU Zotac GTX 1060 6GB AmP Edition with eGPU adapter: BEAST v8.5c mPCIe version, ATX PSU 500watts.
Sorry for REALLY late response.
No i don't found a workaround but wasnt searching yet.
I would also be interested in a workaround.
UPS I DID IT AGAIN!
After selling all my egpu stuff i once again did the EGPU thing and it was FUN
because it worked on the first try. Actually i watched my own video and what i wrote
2 years ago to set it up!
I found a nice way to get the cable out of the way if i don't use the cable.
I just use some very small neodym magnets to hold it in place. Pics below!!!
Also i now have a really nice case for my BEAST!
Here some PICS from EGPU and other Tuning!
Installed some additional cooling for the vrecs how controll the voltage and can get pretty hot!
Some RAM-Cooling for my SSD which sometimes gets over 60 C° Now it stay at 51C° under full load!
I also removed all the dust filters to gain better airflow through the device!
Are there some more L502x lovers who thinks this 2011 Laptop still kicks as ?
Man, what a nice config you got there! I have a L502X myself, and I was thinking about setting up an eGPU too, so I just bought today an used Geforce GTX 570 (yep, an old one just for experimenting purposes + it was really cheap) and my next step was to find out what equipment I should buy to start using this. I have my eye on a Gearbest item ( https://www.gearbest.com/laptop-accessories/pp_229102.html?wid=1433363 ) but I'm not sure if it's a good call. The L502X is on the compatible list, but I have no idea of how its performance is... Can you give me some tips or even send me a link with a good Beast or something? Thanks

Hey Duelroxas! 🙂
Thank you! I use a Beast V 8.0 and i have another one with V.8.5c!
Make shure to get the egpu setup from nando!
Without it you wont get it to work!
see the explanations and the video from my first post on how to set it up with with laptop!
Any questions let me know! I know exactly what to do!
The L502x is still a GREAT machine! Especially with a nice EGPU!
Have fun & best wishes
Thank you very much for putting all this info for L502X. I have GTX 1060 3GB working and I enjoy it very much. Recently I changed too HDD to SSD that has really boosted performance overall.
