I'm back on the EGPU scene after a 4 year hiatus, last build was here. 14" HP 8470P + GTX770@4Gbps+c-EC2 (PE4L 2.1b) + Win8.1 [ jakethesnake438] - Implementation Guides - PC - Tech|Inferno Forums

 

This X1 Extreme has given me some headaches, but most of them were to do with the Lenovo drivers suite

I was having major issues in BF5, where the CPU was pinned at 100%, this was resolved by disabling IGPU and closing the internal screen

 

System specs:

  • 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

eGPU Hardware

Setup

  • Install Win 10 20H2 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 AMD Driver 20.4.2, performance issues with later drivers
  • Close internal screen (for improved BF5 performance)

 

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

 

Performance:

  • Cinebench R20: 3107, fastest score I could find online
  • Battlefield 5: > 60fps @ 4k Low on multiplayer
  • Battlefield 4: > 80fps @ 4k High on multiplayer
  • Ungine Superposition 1080p Extreme: 4546
  • Ungine Superposition 4k Optimized: 6254
  • More to come

Have you tried AMD 20.4.2 driver with the Superposition benchmark?

No problem. Great that it’s working for you! : )

I would like to figure out what has changed with the latest drivers.
