Precision T5600 + Tesla K80 GPU

Hi all,

 

I'm trying to get a K80 running in my T5600 workstation. I've confirmed that the card works in a recent socket 1151 motherboard. I've also installed a spare 1080Ti GPU in the T5600 and it also boots fine.

When I attempt to boot with the K80, it fails during POST with the front LED showing the number 2. According to the documentation this is marked as 'Reserved' so not much help.

I'm wondering whether this issue is that the T5600 motherboard doesn't support large BARs for PCI devices, normally set as "Above 4G decoding". The Tesla K80 is 2x 12G K40's strapped together so a total of 24G of GPU memory. A lot of the posts I've seen talking about disabling CSM and enabling above 4G decoding, I can't see either of these issues in the BIOS ( upgraded to the latest version A19 ).

Is this simply a case of the T5600 motherboard not supporting this, or am I missing?

Thanks.

Hello Dell Support,

I have the same mistake and similar hardware setup. Get diagnostic lamp 2 is always on due to insufficient input/ output when I plug an nVidia Tesla M40 as secondary GPU on my T3600.

Thanks

Two days ago I contacted dell costumer service. After The chat with the assistant I decided to wait two days to post this because I was so angry and don’t want to be unfair in my comment. 
The dell response was fast, I can give them that.
I told them my problem but the response was: Since that gpu was never tested with our T7820 system we cannot help you. I really expected something else from a company that sells millions of devices and has that much costumers. Around the world. Anyway I decided to return my t7820 and stop buying dell workstations personally and in my company.

I have tried in other dell machines as servers, before installing the K80 you need to configure de mapping of the memory.  In other work stations from HP, IBM, or Supermicro, there is an advanced configuration "enable 4g decoding" which allows mapping the ram of the video card.  Also, you need to analyze how mani PCI lines are available on your workstation beside the other cards installed. This is because even recognizing the card can be unusable because of the 'Code 12 (Windows)'.  

Try to enable de decoding, analyze the quantity of PCIe remaining lines, and then install de card. Also, your power supply must have enough power to run all the devices and boot. It must be working. Remember that k80 drains almost 300W at full power.

I'll don't take responsibility for any problem related to applying this procedure.

I know this thread is quite old, but it seems that even trying to run that Tesla is looking for trouble.

I can see why the Dell support said they did not test such as setup. Looking that the spec Tesla K80 | NVIDIA it seems to be a server card with passive cooling. Fine in an ice-cold data centre. Not to sure it would work in a desktop workstation without running dangerously hot.
