Boot with three, disable two from Device Manager. Shut down the machine, put the fourth card back in. Boot, and enable the other two.
EVEN if it works, chances are that you will have to repeat it every reboot. You can try to enable them, test that they work, THEN disable them again - Windows should ask for a reboot, just say no and keep using the computer. On next reboot, you will just have to enable them back from Device Manager. This is assuming you can workaround your issue as I did.
