I've found if you use MSI Afterburner and your miner crashes occasionally for no apparent reason, make sure the CCC.exe (Catalyst Control Centre) process is killed!
generally it is a risk to run two programs changing graphics card parameters at once. with my program clocktweak it might be easier to set mem clocks, it is not free, though.

5850 dont like the memmory underclocked for some reason i spent a good 8 hours flashing, reflashing etc etc the best i could get it down to without it crashing was 800 mhz. 5830s on the other hand seem to have no problem with lower memory speeds.
My 5850 disagrees with you.
It is running stably and at its best @ 950 MHz core/180 MHz memory. I guess it just depends on the individual card.OP, read the first post of this thread (http://forum.bitcoin.org/index.php?topic=4292.0) carefully, and you may need to change the permissions of the .cfg file first, as I did.
THANK YOU THANK YOU THANK YOU
finally i can get this machine running now

Yea I think it has to do with the individual card as well, I just for the life of me could not get it stable. Oh well its still pretty cool even with the higher mem.
As far as lowering your minimums rbe editor is the easist way to do it. Basically edit your bios so your fans are always 100%, ram mins and maxs, etc, etc there is a little bit of a learning curve to the software. You'll see what I mean

also i forgot to add, i have 2 video cards, i need to change both clocking ranges, i need to increase minimums and maximum ranges
Right now i got everything on my Mining Machine Working
the only thing not working right now is OVERCLOCKING / Underclocking
I have used ATI Tray, MSI Afterburner, and as well Riva tuner does not work with 5850 ati radeon (Gigabyte)
What i need right now is advice on what PROGRAM i can use, RIGHT NOW
i need to be able to Change my CLOCKING Ranges, Minimums and Maximums settings to lets say 500 to 800
to GPU Core CLock and like 500 to 1200 range for Memory
Because at this Moment and time EVERY SINGLE F#$#$!@# Time i try to Lower the GPU Core Clock Setting Below 760, it does NOT work, it just Stays at 760, it WILL not Lower itself to 650 or even 725
