its very strange. now that i started mining without teh three flags (vectors, workspace, and bfiint)
then i add them afterwards
now it is NOT shutting down...
anyone know why?

Ubuntu might behave differently since it is a wholly different OS architecture.
See if you have turned off all power saving options. I know that "turning off monitor after x mins" will not crash my 6950, but perhaps there's something else there about sleep state and somesuch. If the monitor loses connection as you are using the machine, then that may be unrelated to the UVD bug, since when that happens, the monitor picture stays frozen and even a hard reset takes a few seconds to be acknowledged.

yeah everything is on high performance, no sleep, no moniter sleep, no hibernate no nuttin.

I still think you have some specific application in the background that kicks in only periodically. Perhaps check your scheduled tasks, or leave task manager open and note down the running applications - since the screen freezes when the radeons hang, you can still read the taskmanager.
the screen loses connection. i checked sched tasks, there are none that i can find. if i am even looking correctly lol.
well ill try the task manager today, im really desperate to find out whats going on cus i wanna buy another rig.
anyway do u think ubuntu might react differently?'
my two 6990s are still running to this moment with the three flags off.(workspace vectors bfi_int)

UPDATE
so heres whats going on. I ran it without vectors, workspace=128, an bfi_int. (pheonix miner)
it never shut down on me. so what i did afterwards was to run it with all of them again, and guess what it still didnt shut down on me for a full 24 hours.
so i decided that it must have been fixed. i decided to just restart the computer just to see what would happen if i shut the computer down, and it started messing up again, this time @ 20 minutes it would just die on me. so here I am again removing the three flags and its running fine again. we will see what happens next time.
hope this can help ppl with 6990

i got a 1250 watt power supply, planning on running three 6990s on it, they will not be overclocked however.
i already changed the sleep settings. anyone know how to hook up the third one using windows 7?

You can't run three 6990s, max of 4 GPUs in CF.
yeah im probably gonna sell it or return it. my third 6990 is useless right now.
but other than that, I am now running phoenix miner instead of guiminer. atfirst it shut down after 20 minutes twice. then i removed VECTORS and also removed WORKSPACE=128 and also removed BFI thingy and only left agression=10.
it has been running for two hours straight, other than the fact that deepbit crashed for 10 minutes, it still ran smoothly, but at 290 per gpu instead of 333.
I am hoping it will run nonstop finally, then i can adjust the script to see which one will let my computer last longer.
ill update tomorrow

Have you tried it with a single card? If your power supply is actually defective, perhaps it will be able to handle one card.
When you install the drivers, do you choose custom and only install the driver and APP? I have no reason to think the other crap will cause any instability, but I always deselect it anyway.

nope i selected express.
Screensavers?
not at all.
the thing about testing it out, is that sometiems it takes a couple of hours sometimes it takes minutes, its so confusing. i was thinking of setting it up without a moniter and see what happens
Screensavers?
Wow, way the go AMD. Way to keep up your reputation for having shitty drivers.
The problem affects a very slim percent of users. If you are running the card as a dedicated opencl accelerator, chances are you aren't the type of guy to hang out on Youtube all day. On a dedicated mining rig, no other app should be running that triggers the bug.
Besides, nVidia drivers aren't any better either. Remember the nforce chipset?
clonedone: run through the windows services, see if there's anything suspicious there (such as Windows Media Center). Also check if there are any scheduled tasks. I run a 6950 and any time it hangs, it's from an application I know I opened, never from something that opened in the background.
i just reformatted the whole system, installed the 11.4 cata, installed guiminer, and started it. it mined for 20 mins, then did the same wierd shutdown, where it dosent fully shut down, but nothing is running except the fans(as far as i can tell). then i restarted it and tried it again, it ran for an hour and shut off. now im trying it again, i never run any other programs or anything else, i updates windows though to service pack 1 for windows 7, but that was after i reformatted, doubt it has anything to do with it.
media center isnt running im sure of it. any other suggestion?

i see... i shouldnt have gotten these cards then... dam
thanks for your help. im not even sure what to do now.
im thinking of setting up a program to restart my computer every hour and then turn on guiminer
that way i can restart my comp b4 the driver issue shuts me down.
what do you think of this plan? maybe it will slow my bitcoin mining down a lot i suppose

What he is saying is that any app that uses the video overlay will crash the card. If this is a dedicated mining rig, no such app should be opening, and it won't crash. So, are you using the computer when this is happening, or is it just sitting somewhere mining?
i was initially using logmein, now im not...but its still installed... ill uninstall it today but i doubt it would make a difference. i dont use this thing for anything else otherwise.

10.4 is where they fixed it for the 58xx series (after half a year of the card being out). Earliest Catalyst to support 6950 is 10.11a, I think, and 6990 support was just added recently. So you can't roll back drivers.
68xx cards are not affected, only the 69xx ones that use the new VLIW4 architecture. Chances are, the upcoming Radeon 7xxx will have this bug too, unless they fix it till then.
The only thing you can do is watch out and not open any apps that trigger the video overlay, while mining. That means most video players, untick "hardware acceleration" for Flash, the Video Settings in CCC, GPU-Z at startup (works fine if you run your miner after gpu-z started up though), pcsx2, and Google Chrome with hardware acceleration enabled - these are the ones I've stumbled across so far.
And, perhaps keep bugging AMD about it. Maybe they'll fix it sooner if more people complain. I wouldn't keep my hopes up, the 58xx series got fixed cause it affected an entire generation of cards, here it only affects 3 cards.

What motherboard are you using that will let you run with 3 cards? Are they spaced far enough apart to allow airflow between?
The card scales back its own clockspeed if temps reach too high. You'd have to instantly reach a meltdown temperature for it to hang outright.
I'm telling you, it's the opencl + video bug. Easy enough to reproduce: Have your mining up running, then go to Catalyst Control Center and try opening the Video Settings menu. Or just launch GPU-Z AFTER you have started up the mining app.
ahh so what do you recommend then? should i downgrade to 10.4?

It's not your PSU. It's a driver bug. Accessing the video overlay when OpenCL apps are running will lock up a 69xx card. 58xx series suffered from this too, but they fixed it in catalyst 10.4. The 69xx is affected even with catalyst 11.4.
