About#
I bought a Zero Moment SER5 MAX, and I couldn't bear the weak performance of Vega 7.
But I still wanted portability, so I chose to use NVMe to SFF-8612 (OCuLink), and if I want to take the computer with me, I just need to unplug the cable.
I'm using the open-source universe's EG01, and it has a more aesthetic design.
The main reason for choosing the Tesla M40 graphics card is actually because I don't have enough money (x).
The performance is still okay, the memory is large, and the most important thing is that it's cheap.
Process#
Arrived, plugged in, turned on, and easily passed the self-test.
It was actually an expected problem. I couldn't find the "Above 4G Decoding" option even after flipping through the entire BIOS, and it was still the same with UAFB.
After searching, I found a tutorial, used UEFITool to find the VarStoreInfo of "Above 4G Decoding", and forcefully enabled it using modGRUBShell.
(Attached: The VarStoreInfo for SER5 MAX is 0xF7)
After enabling it, the computer can boot successfully.
The next step is the normal process of installing drivers~~, modifying the registry to enable WDDM (reference)~~
In fact, it's not necessary. Just run as administrator:
nvidia-smi -dm 0
to switch to WDDM mode.
It's even easier on Linux, just install the proprietary driver and it can be used for graphics rendering directly.
But be sure to disable GSP-RM, otherwise there will be a problem of low frame rate and inability to increase it (source)
sudo su -c 'echo options nvidia NVreg_EnableGpuFirmware=0 > /etc/modprobe.d/nvidia-gsp.conf'
sudo update-initramfs -u #Debian/Ubuntu
sudo mkinitcpio -P #ArchLinux
reboot
Performance & Benchmark#
Horizon 4: High preset in Linux, 1080P at a steady 60 frames per second with occasional minor stuttering. At 2K, it can run at 55-60 frames per second, with more frequent minor stuttering but it doesn't affect the gameplay much.
To do
User Experience#
The graphics dock can be randomly turned on and off, which is great, no need to keep pressing the power button.
The fan is from EVGA's 980Ti, modified with temperature control. It's very quiet when not playing games, and it's not too loud when playing games.
The temperature is well controlled, and no matter what game I play, it won't exceed 50℃.
