Hi,
I have two Asus 5850 DirectCU's. Using Afterburner and CCC 12.1.
AB can change core clock and memory only in GPU1. I can not do anything to GPU2.
With Trixx I can change the memory and core clock on both cards.
System crashes after 2minutes of mining. Without any OC'ing it is stable but MHash/W is so crappy I don't want to run it like that. Any solutions? Tried CrossFire too but same problem.

One of the 5850s has to be the problem. That same computer can run two 5870s without any problems.

Check ASIC quality on the one that is crapping out, I bet it is below 65%.
You must have a 7970 (or similar). Cant get ASIC quality of older GPUs (6xxx or lower).
To the OP, Sapphire Trixx 4.3.0 is out now, which now supports undervolting in addition to overvolting, as well as 7xxx over/underclocking. I don't see any reason to use afterburner anymore. Also there are "bad" memory frequencies where the timings to a certain frequency are too stressful to cause it not to work until it gets past a certain point them jumps to a different set of more stable timings. Try different increments of 5 mhz memory until you find one that works for you. For me, I found 220Mhz+ and 370MHz+ to be breaking points for both of my 5870's.
