We've found Elitebooks typically require a DSDT override to be able to use AMD or GTX9xx/GTX10xx cards due to those requiring PCI apertures > 256MB.

 

So first things first, do you have a 'large memory' Device Manager item in place indicative of the DSDT override working? Pls work through this thread to check: https://www.techinferno.com/index.php?/forums/topic/5874-guide-dsdt-override-to-fix-error-12/

 

Second thing is your PCI compaction with endpoint=56.25GB above failed probably because you have a non-English v:\config\devcon.txt file (run c:\eGPU\eGPU-setup-mount as admin to view) where the "PCI BUS" entry cannot be identified and skipped, but acts to exclude allocation. Pls remove the non-English PCI Bus section or PM me the file contents so I can identify what needs to be removed.

 

so with the edited devcon file it is now possible to set the endpoint to 56.25GB but the gpu won't show up in the device manager. i did remove the 4GB RAM stick leavin just the 2GB in it and everything seems to work.

to use more RAM i need to do a DSDT override .... right?

hi guys hi @Tech Inferno Fan,

i wanted to setup an egpu for my hp elitebook but got the error code 12. so i did get the diy setup 1.3 from nando to get rid of the error but i couldn't manage to do it.

first of all the hardware

hp elitebook 8470p
- i5-3320m
- 4+2 GB RAM
- intel hd graphics 4000 (no dedicated gpu built in)
- 256gb samsung 850 pro ssd
- win 10 pro 64 bit

egpu
- radeon rx480 8gb
- PE4C V3.0 (PCIe x16 Adapter) with expresscard
- dell d220p-01 psu

the tolud is under 3 gigabyte. i was able to hotplug the gpu 2 times while the system was booting up without any errors and could play games. everything worked perfectly. but i don't want to sit 20 minutes everytime hotpluging the egpu until it works. so this is where setup 1.3 comes in. unfortunately i couldn't get it working and need your help.

here are some pics with "failures" i get while setting it up. sorry for my english and thank you.

pic 1: setup 1.3 overview with its status

pic 2: warning i get if i try to test run the chainloader

pic 3: warning i get if i try to set a 36 bit endpoint in pci compaction

pic 4: error i get setting up the pci compaction (error highlighted in red)
