Tech Inferno Fan, you wrote in an earlier post the follwoing;
Disable dGPU for eGPU use? NVidia Optimus will only activate if there is no other AMD or NVidia dGPU detected. Usually we use the Setup 1.30 software to disable dGPUs, but it looks like it's possible to do as a UEFI variable write:Spoiler
0x72F20 Setting: Always Enable PEG, Variable: 0x209 {05 A6 F6 05 F7 05 33 02 02 00 09 02 10 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00}
0x72F46 Option: Disabled, Value: 0x2 {09 0E C0 03 00 00 02 00 00 00 00 00 00 00}
0x72F54 Option: Enabled, Value: 0x1 {09 0E BF 03 00 00 01 00 00 00 00 00 00 00}
0x72F62 Option: Auto, Value: 0x0 {09 0E BD 03 30 00 00 00 00 00 00 00 00 00}
0x72F70 End of Options {29 02}
I extracted the same information from E6530A16.exe and found the following as default values;
0x5F915 Setting: Always Enable PEG, Variable: 0x187 {05 A6 4D 03 4E 03 85 01 02 00 87 01 10 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00}
0x5F93B Option: Disabled, Value: 0x2 {09 0E C1 02 00 00 02 00 00 00 00 00 00 00}
0x5F949 Option: Enabled, Value: 0x1 {09 0E C0 02 00 00 01 00 00 00 00 00 00 00}
0x5F957 Option: Auto, Value: 0x0 {09 0E BE 02 30 00 00 00 00 00 00 00 00 00}
0x5F965 End of Options {29 02}
Do you know which values i should modify to disable the dGPU?

Hi,
I'm trying to set up a rig with the following components were the eGPU is powering the internal LCD.
DELL Latitude E6530
BIOS A16
i7 3520M
16 Gbyte ram
Intel HD Graphics 4000 (driver version 15.33.32.64.4061)
NVIDIA NVS 5200M (driver version 347.88)
EXP GDC Beast, CTD Off, PTD Off, connected with Expresscard
NVIDIA GeForce GTX 770 (driver version 347.88)
Windows 7 64bit
OCZ 600W external PSU
So far all three GPU's are detected by Device Manager in Windows, but only if i boot with eGPU connected. eGPU is running at PCI-E x1 1.1 according to GPU-Z. I can only access NVIDIA control panel if i have an external LCD connected to my eGPU and I can't get the eGPU to power my internal LCD even if the external LCD is unplugged. In 3DMark Vantage i have about 100 FPS on external LCD and about 10 FPS on internal LCD. Any suggestions how to solve this problem?
3DMark Vantage Graphic Score 29563 on external LCD
NVIDIA GeForce GTX 770 video card benchmark result - Intel Core i7-3520M,Dell Inc. 07Y85M
Update:
By using DIY eGPU Setup 1.30 i managed to disable dGPU and feed the internal LCD with my eGPU. i'm also running my eGPU at PCI-E x1 2.0 now.
Settings in startup.bat
call speedup lbacache
call iport reset 1
call iport gen2 1
call iport dGPU off
:end
call chainload bootmgr noremap
3DMark Vantage Graphic Score 18210 on internal LCD

Tech Inferno Fan, did you manage to disable the dGPU using UEFI variables?
This is what my extract from E6530A16.exe looks like. Do you know what to modify to disable dGPU?
