2012 14" HP EliteBook 8470P [3rd,2C,M] + 9600 GT @ 4Gbps-EC2 (PCE164P-N03) + Win10 [diyman]  

• CPU: Intel Core i5-3210M
• RAM: 2x4GB DDR3 1600MHz
• iGPU: Intel HD4000 650-1100MHz
• dGPU: none
• OS: Windows 10 Pro ver.1709 and 1803
• External display: Samsung SA300 - 19" - 1366x768

• VGA: XFX 9600GT 512MB DDR3 (lower gpu and memory clocks, than reference; no external power connector)
• PSU: Codegen 300W ATX (in a Codegen 450W case with 120mm fan)
• eGPU: $7 PCE164P-N03  with 60cm USB 3.0 cable (default PCI-e to mPCI-e) + US$5 Expresscard USB extension

• VGA: NVIDIA Geforce GTX 560 (reference clocks)
• PSU: Codegen 450W ATX (without factory case)
• eGPU: $7 PCE164P-N03  with 100cm USB 3.0 cable (default PCI-e to mPCI-e) + US$5 Expresscard USB extension

       notice: With the 100cm blue USB 3.0 cable, the eGPU work only with ExpressCard gen1.

The WWAN mPCI-e slot is whitelist locked, the WLAN mPCI-e slot is unlocked, but can’t detect anyway the eGPU. I tried everything on the link, but nothing. That's why i did the Expresscard mod.

Plug the powered eGPU to loaded Windows.

Only at your own risk!

error 12 - eGPU.io DSDT override

Before all, detach the eGPU

1.) Step 1.
2.) Step 2. - Option 2. (I used with UEFI) (Option 1. need "testing mode" -> can't play  e.g. Fortnite)

2.1) Mount S:\ and backup "BOOTX64.efi" file with CMD as Admin

[Please login to see this]

2.2) Download Clover. 

2.3)Open the downloaded file with 7-zip, and copy "EFI" to "C:\EFI" manually.

2.4) Copy "C:\EFI" to "S:\EFI" with CMD as Admin (overwrite, hidden files) (source)

[Please login to see this]

2.5) Make target dir and copy the modified dsdt file

[Please login to see this]

2.6) "Reboot via Clover -> Windows EFI menu and proceed to step 3 to confirm it worked."
2.6.1) Shutdown
2.6.2) In UEFI BIOS set boot priority first place "Customized boot"
2.6.3) Set Custom Boot path to "\EFI\CLOVER\CLOVERX64.efi".
2.6.4) Save and exit

Clover

After save, the system boot to clover automatically. The "Timeout" parameter default 5sec, this can edit.

Optional: Hide Clover select screen on boot
1.) Edit C:\EFI\CLOVER\config.plist file with Notepad++
2.) Search "Timeout" word (result normally in line 291)
3.) The next line have the value of timeout in seconds, you can set to "0" for hide clover's screen at boot

3.) I don't have "Large Memory", but the error 12 is fixed.

error 43 - NVIDIA reg key delete

1.) Follow steps of link

• I used the last (342.01) and a older (341.92) driver for Geforce 9600GT.

Sometimes after boot, I get error 43 for Intel HD 4000 and Nvidia 9600GT too.

The solution: 

Using after istallations and errors solving

When connect the eGPU to loaded Windows, the Wi-Fi is broken, and the system becomes unstable.

That is why you have to connect when you see "Press Esc to BIOS" before Clover. You may need to turn off the "Fast boot" or set bios menu timeout.

Plans

• Delay circuit for dynamism
• eGPU auto power on, when connect the Expresscard
• maybe replace USB 3.0 Type A to 3.0 mini-B -> USB Type-C to Type-C for more pins (need more wires for USB 2.0 and the auto power on)
• GT 1030 (~30W) or GTX 1050 (~75W),  96W notebook charger (12V/8A)
• Custom case:
  • In real life
  • Render images:
    • The green box has the same size as the MSI GT 1030 AERO ITX 2G OC (147 x 102 x 38 mm)
    • Dimensions of case: 257 x 230 x 60 mm
    • The Power Supply is the Codegen 450W without ATX case, on standoffs
    • The VGA mounter/holder is a Dual slot Compaq SFF riser, like this (modified for case) 
      

Comments

• I can use extend, primary and second screen.
• The 9600GT 600MHz/700MHz (gpu/mem) slower than Intel HD 4000.
• The GTX 560 big performance jump after the HD4000 or 9600GT.
