I think X708 ups are not compatible with X750 ups in any way.  

dmesg log also has such messages on each attempt to read from ssd: "nvme I/O 960 (I/O Cmd) QID 3 timeout, aborting"

Hi! I've installed X1002 with NVMe (non-Phison chipset). Then I booted to linux OS and put dtparam=pciex1 to config.txt - it let the SSD drive to become visible. But it operates VERY slow! It makes...

I found my problem. My SSD has Phison controller. As noted in https://geekworm.com/products/x1001 it's not compitable. 

Update:Imaged an USB drive.  Without the SSD plugged into the Pi it boots fine with the USB drive. With the SSD inserted in the hat it won't start (green light, full fans & no HDMI output)...

I tried all suggestions above, but my Pi5 won't boot with the X1001 hat. The blue light is on, but nothing happens (Pi5 light is green, screen show no signal and fans are noisy). The Pi5 also does ...

@Ivan Podogov If your DOS partition was obtained by flashing the Raspberry Pi OS, it should be fine, but many users are using OLD SSDs, which will have old OS on them, such as windows 10 or other O...

We've found customer feedback that they don't recognize SSDs, the firmware & configuration are fine, and there's no problem with the power supply. But just not recognized. The final solution i...

Based on the schematics shown, I think the fan contoller you found would work.  It's a very similar design to the one I used (perhaps better). Connect the fan to JP2 pins 1 & 2 (minding t...

Thank you for the excellent solution, I just ordered this from Tindie. Unfortunately, the shipping for Tindie products to Europe costs more than the fan controller itself. In Germany, I only foun...

Note, the kvmd-fan code to fix the PWM mode is on the "pwm_mode" branch of the forked repository linked above.

The 30mm fan that comes with the A3 kit is only a two wire fan, and is connected directly to 5V power.  It runs at full speed all the time.  However, with a little mod, you can get a PWM ...

You are absolutely right, I recently saw such a case, if I see it again, then I will share the resource

If you have documentation or libraries provided by the x728 UPS manufacturer to interact with it via Python, you should refer to that documentation or official resources for information on how to g...

The error you received may be because the python-smbus package is missing from your repository or is not available for installation from standard sources. The package may be available from another ...

Similar problem here.   However, I see no PCIe light on the 1001 (but the SSD LED is blue) and lspci only shows: 0001:00:00.0 PCI bridge: Broadcom Inc. and subsidiaries Device 2712 (rev ...

since there was no reply to this, I ended up picking up the Pimoroni NVMe Base for Pi 5 and it worked flawlessly, and with far fewer commands! You simply write an SD card, boot, get latest eeprom u...

@Kevin Sporinsky Where can I find the answers to your questions? I have the same questions.

For optimal cooling with the Gemini x882, consider Cooling Solution for a stellar performance. But here's a pro tip – while you're optimizing your setup, take a moment to dive into the coolin...

@Peter Schneider  Did you ever solve this issue? I'm fairly picky with noise and this device seems well priced but I don't need to have a whine coming out of the study, my wife will kill me.
