My work just got a K20 and I am about to download the driver from Nvidia, but see that there are three different drivers, K20Xm, K20m, and K20c.
When I look at the card I just see K20 with no other qualifier. It just says Tesla K20 on the side on on the bottom.
Did Google this first, and could not find an answer, so maybe someone here can help. I think it is probably a K20m but would rather know for sure.
Is there any identifying trait on the card which indicates the model type?
