Any Tesla K20c Help would be appreciated

I have spent this week trying to find solutions for my Tesla K20c card issues but with no success. I can’t seem to get my Tesla card to display in Blender 2.71 compute devices.

This is what I have to work with:

z820 workstation
2 Xeon 16core Processors
64X system
Win7 Enterprise
Quadro K2000 (works well in blender)
Tesla K20c (doesn’t not appear in blender)
64GB RAM

I’m trying to get my Tesla card to work and if anyone can help I would greatly appreciate it.

Thanks in advance,

Vince
