I think this was afterburner trying to give them the same clocks, even though the 5850 extreme isnt stable at 850/1200 with stock voltage.

Try uninstalling afterburner to solve the crashes if you have it.
Both my cards are pretty bad at OC so i just set them at 775/1050 @ 1.2v(so no , not pre-overclocked) , but that's something i could try.

It's most definitely ULPS that's causing your issues, I can't think of anything else.

Go to registry and disable Ulps:

[HKEY_LOCAL_MACHINE\\SYSTEM\\ControlSet001\\Control \\Cl ass\\{4D36E968-E325-11CE-BFC1-08002BE10318}]

and change "EnableUlps" to 0 under the 0000 and 0001 or 0003 keys.

IIRC, Afterburner lets you set fan profiles for individual cards when in CF.
