Hello everyone!

Quite new to this forum and eGPU builds in general. I've got a new setup and I thought about sharing the benchmarks because I've not seen anyone with this specific build. I'm also going to share my experiences, because there have been a few hurdles.

System Specs

Model 2019 Dell Precision 5540
CPU i9-9880H 8 Core, 16MB Cache, 2.30GHz up to 4.80GHz Turbo, 45W, vPro
dGPU NVIDIA Quadro® T2000 w/4GB GDDR5
iGPU Intel® UHD Graphics 630
HDD M.2 2280, 1 TB, PCIe, Class 40 SSD
Memory 32 GB, DDR4, 2666 MHz

eGPU Hardware

Razer Core X Chroma + MSI GeForce RTX 2080 Ti Gaming X Trio 11Gb + 0.5m TB3 cable


There were a few issues that occurred during setup, both from inexperience with eGPU and from software.

During setup I had to add a PCIe splitter, because the Razer Core X Chroma Power Supply only comes with 2x 8-pin PCIe cable. I added a Y-splitter to get the required 2x 8-pin, 1x 6-pin PCIe power required for the graphics card.

The first issue that I was running into was that the laptop did recognize the eGPU. It was registered as Nvidia RTX 2080 Ti in device manager. But no image would show up on the external monitor. Also Nvidia Control Panel would not recognize the eGPU at all. After enabling Thunderbolt pre-boot modules i found out the graphics card didn't have sufficient power and refused to start on boot. I realized I've bought a 8-pin to 2x 8-pin splitter, but I could only connect 6-pin to the 8-pin connector, and it was not good enough. I replaced the splitter for 6-pin to 2x8-pin splitter. Tada! Image is now produced on the external monitor and Nvidia Control Panel recognized the eGPU.

Next issue was stuttering during benchmarks, and random total freezing after 5 - 10 minutes when the computer was under low workload. I figured it was due to Power State Link Management that have been written on the forum. However the Dell Power Schema does not allow me to configure it. I had to go into registry and add it myself through these steps:

1. Find the Key that has "FriendlyName: Dell" in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes (For me the key was 49ef8fc0-bb7f-488e-b6a0-f1fc77ec649b).
2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\501a4d13-42af-4429-9fd1-a8218c268e20\ee12f906-d277-404b-b6da-e5fa1a576df5\DefaultPowerSchemeValues and add that Key.
3. Add AcSettingIndex and DcSettingIndex REG_DWORD with value 0

The Benchmark is run with the current latest Nvidia Driver 442.19 and on an external monitor Asus ROG Swift PG348Q 34" 100Hz and Gsync enabled.

Nice share! I also have a build very similar to yours. Same laptop model, processor, dGPU, and eGPU enclosure. You're not alone 😛

When you purchased your 5540 laptop, how did you configure it? I chose the tier 1 option and then customized the CPU and dGPU to be the same as the prebuilt tier 4 option. I bought my extra RAM and storage separately. It saved me about $1100.
