I will now try to remove every cards except the 5850 and work from there.
why don't you focus on one item at a time. start with the core speed. don't try to jack it up as far as you can, just see if you can reliably change it from the default to a little higher.
once that works, do the same for mem speed. make sure you are able to change the values a little before you go hog wild and shoot for the Mh/s record.
one item at a time, slowly towards your goal. this is the only way to determine where the limitation lies.
