RE: Nvidia Tesla P4 Low Profile GPU upgrade
Hi, been reading this post and figure I should contribute to what I learned from this posting.
In the process of upgrading my M920q. Just added a NVidia Tesla P4 Low Profile with a 01AJ940 PCIe connector. Setup is with i5-8500T, 8Gb RAM, Win 11 Pro.
Drilled some holes in the cover and attached a USB fan (Eluteng USB 120mm 2sp) to the back USB port, which turns on when the system boots.
Works pretty good so far.
Did a rough GPU test with Topaz Photo AI on a 40Mb image, P4 vs stock UHD630 ... Image processed (DeNoise, Sharpen, Face, Enhance) took P4 2:05min vs UHD630 13:07min. This includes both CPU time and likely some disk swapping on 8Gb.
Temperature with the cover plate removed, P4 is about 90 Celsius without fan, 75 with fan on low, and 65 with on high.
The P4 fits but had to remove the rear plate. Also removed the front plate to facilitate fan cooling. I'll probably modify the back plate in the future to cover the back chasis a little better, also may put some resilient blocking to secure the P4 inside the case a little better.
Got the P4 on fleabay making an offer for $90. Hoping to receive a i9-9900es from AliX next week to see if I can run the CPU on stock 01MN633 fan-cooler with some extra cooling form my external 120mm USB fan.
Currently using 528.89 data center Tesla drivers from Nvidia driver download. After install, to use WDDM mode, in Command Prompt window, go to "C:\Windows\System32\DriverStore\FileRepository\nvgridsw.inf_amd64_d73757dc15285182" or something similar, and type "nvidia-smi -dm 0"
You may need to reboot to see the P4 in Windows Task Manager
