FAH sleeping

[mk24spitfire]

I upgraded my video cards (previously two nvidia 8800 GTX in SLI) to single nvidia GTX 570. Upgraded to FAH 6.41r2. Tray icon for FAH says it is sleeping and it is apparent no work is being done. Running 270.61 graphics driver. Would appreciate any help as I bought the GTX 570 to process more work due to higher number of cores.

Welcome to foldingforum.org, mk24spitfire. (Did you ever fly one?)

Replacing a G80 GPU with a Fermi GPU requires a re-installation of both drivers and of the latest version of the GPU client. Your GTX 570 is being given work for an 8800 GTX and it's not able to process it.

I had been using the 270.61 drivers with the (2) 8800 GTX cards. I uninstalled the drivers prior to changing to the GTX 570 card. I re-installed the nVidia 270.61 drivers. While using the 8800 GTX cards I was using the FAH 6.23 software. After card change I downloaded the FAH 6.41r2 version and installed it. FAH is still sleeping

Unfortunately, we have reports of problems with those drivers. viewtopic.php?f=59&t=18121

Apparently there are no dependable drivers for the 570 yet.
