R730 and NVIDIA Tesla K80 - Not Detected?
So, I first struggled to get the K80 powered. I found the proper cable for the NVIDIA as it appears the pinning may be specific. Prior, the system would fail to boot and report an over-current situation. With the proper power cable for the card, the system now boots.
My problem NOW is that Windows Server 2016 just doesn't appear to see the card at all. It doesn't show up in Device Manager, and when attempting to install the NVIDIA drivers, the installer immediately fails and says it can't find compatible hardware. There's also no other hardware in Device Manager that would otherwise be the card just improperly classified, etc. It's simply not being seen.
I've searched in the BIOS but I didn't see anything there that looked suspicious. I've also enabled hardware inventory updates, but I don't think that has any impact here, either. Any ideas? Am I missing something that needs to be enabled?
I've installed the card on Riser 3 if that's meaningful.
Thanks!

I was just able to solve this.
The solution was silly, but it worked - I simply reset the card in the PCIe slot and also flipped around the power cable. I expect the cable had nothing to do with it, but I'm including it here anyway since it technically was a variable that changed. The card looked and felt firmly seated, but nonetheless perhaps it wasn't fully?
In any case, when the machine booted, I noticed that it booted differently - fans were at full speed for a good 10 or 15 seconds during the boot sequence which never happens. Once into Windows, the Device Manager immediately showed two "3D Video Device" (the K80 has two GPUs on it). The NVIDIA installer then worked perfectly.
So, net result - it was likely that the card was just not fully seated. Thanks for the help nonetheless.

Hey ezmaass,
saw your PM, nice to see that you found the correct cable.
So what about the PSUs are there 2 1100W PSUs in this system? Like it's mentioned here (https://dell.to/3fDd7Ci).
NOTE: When using the system with the Nvidia K80 GPU card, ensure that you install both PSUs with a minimum of 1100 W each and set the PSU configuration to non-redundant mode.
Best regards,
Stefan

Exact same issue happened to 2 of my gpu servers. swapped the cable around the other way and reseated cards and it booted fine, and perfect since

Hi, could you please tell us about your experience with the usage of K80? I would like to buy one for image segmentation-based deep learning models.

Hello,
Did you guys have any problems with the fans? After installing the GPU with the cable part number N08NH, the fans average at 77% in idle, no load on the server. Is this normal ?
Temperatures below:
CPU1 Temp 41 °C (105.8 °F)
CPU2 Temp 41 °C (105.8 °F)
System Board Exhaust Temp 34 °C (93.2 °F)
System Board Inlet Temp 30 °C (86.0 °F)
Kind regards,
Andrei
