GeForce 7600 does not work together with Tesla K40 under Windows 7

I have a Geforce 7600 and a Tesla K40 GPU on my desktop. However they won’t work together no matter which driver I install (307.83 or 332.76). There is always one card not working and a yellow “!” mark showing in the device manager. It used to work when I had a Geforce 7600 with a Tesla K20.

Which driver(s) should I install to make them work in the same time? Thanks!

From the release notes of the latest GeForce 7 driver:

“Legacy Support Notification: GeForce 6-series and GeForce 7-series GPUs will be moved to legacy support after GeForce R304 drivers (304.xx to 309.xx). GeForce R310 drivers will not support these products.”

I don’t think Tesla K40 would work with 304-309 drivers, considering you tried the 307 and it does not work, so the solution is replacing the ancient 7600 with something else. Cheapest option with most bang for your buck to drive a display would be this: http://www.ebay.com/itm/161206469548. I’m using one now to drive display(s) and have a Quadro K6000 and GTX Titan Black for compute.
