ADT-Link R43SG M.2 eGPU Adapter - No Detection & PCI Resource Error

After testing the ADT-Link R43SG successfully with a 2019 16″ MacBook Pro through an M.2 to Thunderbolt mainboard, I tried direct M.2 interface. Unfortunately this has been more challenging than anticipated. The two host laptops I tested so far both have two M.2 NVMe slots (Alienware 13 R3 and MSI Prestige 15).

One of the two slots is occupied by NVMe Windows boot drive. The other hosts the R43SG M.2 connector. The eGPU testing subject was an AORUS RTX 2070 ITX card removed from the Gaming Box. It fits the ADT-Link R43SG footprint nicely and can work with Dell DA-2 power brick.

The Alienware 13 R3 struggled booting up the first time with M.2 eGPU connected. It eventually booted into Windows but there was no sign of the eGPU. I tried switching the M.2 slot but no change in detection.

The MSI Prestige 15 immediately showed a PCI RESOURCE ERROR screen when it found a foreign M.2 device connected. When I checked the PCIe M.2 slots the BIOS showed empty.

Ideally I’d like to make it work on the Alienware 13R3 because this laptop already has Alienware Graphics Amplifier port and Thunderbolt 3 port. Having the third interface through M.2 PCIe would allow me to compare the three eGPU options.

On the ADT-Link R43SG, set the following and try again:

J1 = open (PERST# delay enabled)
SW2 = 2 (PERST# delay 4.5s)

@nando4 I removed jumper from J1 to open the two metal contacts then push the toggle switch SW2 to position 2. Unfortunately Windows was not able to detect the M.2 eGPU still.

For the AW13 R3 suggest clear CMOS/UEFI  as explained below from service manual. After which boot with the eGPU attached and ADT-Link R43SG switches/jumpers in default settings.

Clearing CMOS settings

  1. Remove the base cover.
  2. Remove the wireless card.
  3. Remove the solid-state drive.
  4. Remove the rear I/O cover.
  5. Remove the computer base.
  6. Remove the battery.
  7. Remove the coin-cell battery.

Wait for one minute.

  1. Replace the coin-cell battery.
  2. Replace the battery.
  3. Replace the computer base.
  4. Replace the rear I/O cover
  5. Replace the solid-state drive.
  6. Replace the wireless card.
  7. Replace the base cover.

@nando4 I was able to disconnect CMOS coin battery without removing rear I/O cover and base cover. Unfortunately clearing the CMOS/UEFI didn’t help with detection.

@atadam I will try again this coming week with a different PSU (SFX) and a Radeon card.
