ill be honest with ya, im catching a train in 40 mins need to do something to kill the time
but its a serious issue. im wondering whats going to happen to all those guys who have a 4870 and are experiencing this issue.-

Guys, the only people complaining here are Cyber-Mav and Roff.
Look in the dictionary under "nvidia fanboy".

I'm really not sure what to think on the whole issue. On the one hand, it's just a one-off scenario that doesn't really affect anything else. On the other, it doesn't affect anything else at the moment. What happens if somebody does use calculations like those in a game or something (GPGPU?) in the future? Since I'm planning on keeping the card for a while, what if the voltage regulators degrade over time to the point where normal applications are affected*? It's no good to me if it just about outlasts the warranty period and then starts going wobbly, IMO.
*I honestly don't know if that can happen or not.

thats funny comming from someone who owns a 4870. are you having a stab at us because your card blacked out on you?
keep the fanboism out of this thread pal its a serious discussion about a serious flaw and im seriously interested in finding out how serious ati will take this issue to be and see if there is any serious compensation that comes out of this.
it is a tricky situation. looking from amd's point of view, they can argue the fact that it is only 2 apps that cause this issue to occur. but on the other hand the biggest question is, why doesnt the core go into protection mode before the power supply on the card does? the gpu obviously wants more power, and it can handle the power as is shown on 4 phase power regulated cards.
fixing this issues is gonna be costly. but im not sure wether amd will fix it for existing cards. although they have said they will fix it for future cards. dont know where those guys with current 4870 cards stand. possibly they get a free exchange with a 5870?

I wouldn't say that Rroff has been particularly bad personally.

Seriously?
Probably because the only time you actually can load the GPU up in such a fashion is using an artificial tool that has no baring on any real world situation. I hate to use a car analogy, but if I sat my car in neutral and kept my foot on the accelerator something would fail sooner rather than later, why did they make a car that the user is not allowed to use at 100%. A similar situation to what we have here.
It could be worse, the GPU's could melt themselves instead of just failing.
I think thats dead on really - the problem is exactly like putting a car in neutral putting your foot to the floor and then wondering why the engine failed after awhile...
I don't think the 8800GTX even the mobile part is in the failure catagory - its just G84/86 mobile parts and some batches of G84/86 desktop parts.
I've not been complaining
The calculations are not the problem. useing all the shaders for that calculation are & the game would be nothing more than coloured background as doing anything else would mean that the shaders are not all working on that calculation.
FUD

I'm not sure you can call it a serious flaw, it only exists in circumstances that are completely artificial.
Made me lol.
ati and nvidia are probably using tools like occt and furmark to simulate the maximum load ever possible on thier gpus then they can use that data to go about making the power regulation circuitry for it.
in reality they probably have the power regulation circuits pre-calculated out.
ati must have known that thier gpu is theoretically capable of pulling 85+ amps of current. as nvidia are aware of the upper limits of thier gpus current pull.
ati chose to implement cheaper power regulation, they never expected this to come back and bite them in the butt.
as for your car analogy, even if you put a car in neutral it will not blow up from being floored instantly. here is a quick youtube vid to show that
the ati cards power off within seconds of being run in occt. so your car analogy doesnt work here.

artificial, hard to say, its not done using any special methods though, it uses basic direct3d shaders, its nothing special as a test nothing fancy.
truth is no actual game currently out there has ever shown this sort of problem or behaviour to be reveal on these cards. so the relief is that its not going to effect your gaming... not yet anyways.
but regardless of it not being "exploited" by any game its still a problem. id personally not be happy having a card that did this on me.

It'd probably work in the literal sense too - you slam your foot down on any 4xxx series card and it'd probably break pretty quickly.
Oh for gods sake this is a problem that only happens when occt is run so far and i remember their new psu test blowing a few psu's does that mean all the makers of those psu's were at fault as well 
. You can get as complicated as you like about this but the reality is chances of this affecting many customer's in the normal working life of these cards is slim to non existent.
Mav seriously you have to go and get some help for this rabid anti ati thing you have going on because whenever i see you commenting on ati i disregard it straight away. I do like the way certain people on here have flagged this as a fault on the part of ati rather then possibly the fault of the software developer who may have made a **** up on his ene.
Nothing works at theoretical max limits for long and they are not meant too they are merely meant to be capable of that max limit under all ideal conditions. Honeslty this really isn't the problem some are making it out to be and it wouldn't be a big deal if we were talking about this affecting nv cards either before i get accused of being a fanboy because i own an X2.
