2019 15" Lenovo ThinkPad X1 Extreme Gen 2 (GTX1650) [9th,6C,H] + RTX 3080 Ti @ 32Gbps-TB3 (AKiTiO Node) + Linux popOS 21.04 & Win10 21H1
I recently upgraded my EGPU to a RTX 3080 Ti, which has resulted in a massive performance improvement
This also required me to upgrade the PSU of the Node, where I chose the CoolerMaster V750 SFX.
I did also pick up a ADT-Link R43SG, but have been unable to get that working, seems its not getting clk signal
- Lenovo X1 Extreme Gen 2, removed mesh on air intake for better airflow
- 2.6 GHz Intel Core i7 9750H (Liquid Metal) Happily sits at 90deg C @ 3.990ghz, ambient ~21 deg C
- 32GB 2x16 2666mhz Ram
- Intel HD Graphics + Nvidia GTX 1650 Max-Q
- Akitio Node Upgraded with Cooler Master V750 SFX
- EVGA RTX 3080 Ti XC3 Ultra, the only powerful gpu I could find that would fit in this enclosure
- Included 30CM TB3 cable
- Phillips 34" 3840x1440 Display
- Install Win 10 Fresh from MS site, don't use Lenovos recovery
- Disable Thunderbolt security in BIOS
- Install drivers manually from Lenovo. Key driver is the Intel Thermal Platform driver, this enables CPU to break 80deg C soft limit
- Don't enable Hyper-V or any WSL support, this causes issues with windows writing to some thermal related registers as referenced here
- Install forked version of TPFanControl from here
- Install latest nvidia driver
- Close internal screen, disable iGPU and dGPU (for improved BF5 performance)
- Install popOS 21.04 (nvidia)
- Set 'nvidia graphics' from power menu
- Follow egpu-switcher installation instructions https://github.com/hertg/egpu-switcher
- run egpu-setup, setting 3080Ti as the egpu
Tuning with throttlestop:
- Undervolted @ -200.2 Core, -150 Cache, -90 SA,
- IccMax @ 255.75A
- Disable and Lock Turbo Power Limits
- Turbo power long max at 80w
- Short power max at 90w
- PL4 130
- PP0 ignored
- Cinebench R20: 3107, fastest score I could find online
Battlefield 5: ~ 80fps (stuttery) @ 3440x1440 (ext) Low on multiplayer
- Battlefield 5: ~100 FPS @ 3440x1440 (ext) mixed on multiplayer (Future framer rendering fixed this for me)
- Battlefield 4: ~160fps @ 3440x1440 (ext) ultra on multiplayer
- Ungine Superposition 1080p Extreme: 10987 (ext)
- Ungine Superposition 4k Optimized: 14326 (ext)
- Happy to run other benches at request
Did you have to modify the Node or add jumpers to install the CoolerMaster V750 SFX? Is the stock Node front exhaust fan sufficient to cool your RTX 3080 Ti? Most importantly (for me), how does the CoolerMaster PS fan compare to the original Node PS fan (mine is quite noisy).
Wow - an RTX 3080 Ti eGPU build! Awesome! I wish you the best of luck with it! I know I'd be having a blast
@cnon297, yeah I used a PSU jumper to control PSU power, but this can be done pretty easily with a paperclip or random piece of wire.
RE cooling, the PSU fan is so much quieter now, biggest noise complaint is the Node front fan now.
Since the GPU isn't a blower cooler, I reversed the fan so it blows air out the front of the case, this was trivial.
I'll probably replace the fan with something else when I can get my hands on a soldering iron.
While gaming, the GPU sits around 83deg C
