Quadro M5000 ECC memory on and sleep issue

[ex-basis]

Hi, has anyone experienced the issue of no wake-up display after Windows 10 enters sleep mode on any HP workstations with Quadro M5000 and ECC enabled? No matter which Nvidia driver I try, the display fails to wake up. GPUMemTest says memory is fine.

This happens from time to time on some cards...not all the time though!

Edit: also had on M5000 - no BIOS text screen also...maybe it is M5000?!

Do not know why, though.

OK, but can you confirm based on your experience whether this is a common issue? What other GPUs are you referring to? This is my first GPU with ECC memory, so I'm confused about what to do in my client's workstation, where ECC is needed but they also want to use sleep mode. Maybe it's just an issue specific to this particular HP workstation model.

When I find out more I will share here
