Do we really? It has not happened yet in games as far as I know, and from the explanation AMD gave it will only happen in artificially created load scenarios (not even GPGPU stuff), hence I am perfectly happy with it.Quote:

Probably because it has kept the issue at bay a little more like in my situation to where they were just like ahh f it and left it at that.
I how ever would like no crashes at all because of this over heating issue with the damn VRMs. I have been in the scene for awhile now and do have a decent amount of knowledge when it comes to overclocking and tweaking and building PCs so don't treat me like I don't.
Tetedeiench, are any 4850's affected? I mean they are just 4870's without GDDR5...I've just updated to 3.1.0 from 3.0.1 today and I'll run it 4850 stock, (625/1986) then 680/2100 (my ASUS top factory default) then 715/2150 which is my current overclock to see what works and doesn't work.
I did not call you or anyone else an idiot, I merely suggested that you could have done some more research before changing the cooling solution. It never hurts to do a little more research. There was a huge thread about VRM cooling in the water cooling section just after the 4870 was released (around last summer?), and I remember reading a thread in the air cooling section as well about someone having trouble with overheating with the ramsinks that came with a Thermalright T-rad. Largon suggested on the previous page that your VRM cooling was inadequate, no, actually, he said they were terribly inadequate:Quote:

What temps do you see while gaming? You may just have a bad card, it happens but your crash is not related to this "issue".Quote:

The one about air cooling might very well be the one I was looking around on already. Does any one know how to use the original plates that come with the coolers for cooling these things?
Because it's being done using standard API calls, meaning anybody could do it !! So IMO it's a design flaw when the card can't handle 100 % load at default clocks.Quote:

The card should never fault because of a cheap power design, ON STOCK CLOCKS AND VOLTS.Quote:

You said it was when it reaches the 82a/83a line, which I said is not true because I did reach above 83 and it functioned normally. Thats besides the point now :)Quote:

Seems a bit risky.. someone willing to run occt for a few days on their non-reference to see what happens?
On second thought, what ATI said makes sense. It is no practical scenario where you are stressing all the units including texturing and computing units at the same time... thats like having a game scene that needs no I/O, doing ridiculously inefficient calculations in the back to use up all the shaders...
No meaningful calculation can max the GPU at 100% in all components 100% of the time. Unless it is an infinite loop with no purpose.
I agree that its nice that ATi is going to address the issue.Quote:

Using that same argument I can say every harddrive ever made has a design flaw because you can format it(using "standard", built in tools) and lose all data. :rolleyes: The only way a HDD will become formated is if I go out of my way, and well, run a format on it.

I'm happy that this is how it turned out. I was kind of expecting AMD to ignore the problem. But perhaps the same mindset that is working for their processor division ( interfacing with the enthusiast community ) has spread to other divisions. Even though overclockers are a small market segment, and the problem is an extreme corner case, they still listened and are redesigning the chip and board. I would suggest that far from the blunder that many have claimed, this could actually bode well for their reputation.
+1 to that. Lets see what the R8xx series will do :).Quote:

my Gainward 4870 reference already goes to 72A in crysis at 1600x1200 no aa no af catalyst driver defaults 9.5 after about 5 minutes
and it crashes after 30 mins -1 hour ...seems to be very random maybe it spikes to 83 A causing it to crash

don't use the riva osd ingame because you will get false data .let riva monitor your card in the background
now imagine i used a higher rezolution like 2500 ....it would crash wouldn't it ?
i say HAAA again
Since it takes so long to happen, it doesn't really sound like the same issue. RMA your card.
i just ran the crysis gpu benchmark and this is what i got
http://img132.imageshack.us/img132/8...ysisgpu.th.jpg
the 72 Amps that i got were during actual gameplay using the carrier level fighting the huge alien ships
why do my clocks go from 2dto 3d mode every damn second i don't see that happening on your card
damn you ati or gainward or whoever fault it is XD
i'm so tired of this problem i just want to play my games without crashing QQ
all my crysis runs were made without AA or AF using catalyst 9.5 default settings and yes i notice a higher amperage without the AA in your screenshot
i also notice that my clocks go from 2d to 3d mode every damn second i don't see that happening on your card !!
can you tell me if your card is reference 4870 512 gddr5 and who produced it ? mine is gainward made
could you please save your video bios file using gpu-z 0.3.3 (latest version) so i can try it on my card ? maybe it will make it stop swithing from 2d to 3d mode ...maybe that is the problem
all reference cards bios should be compatible with one another
here are some pics of my card

Is this the HSF combo you are using with your PC? I was hoping to see an actual pic of your video card. In any case I've noticed that when dust build up at/near the vrm area of the video card it not only creates more heat but caused my video card to use more power. On a hunch I decided to clean that area out. I removed the front plate and took a can of air and sprayed in and around the vrm area. Doing so created a plume of dust. After air cleaning I noticed that my temps were lower and power consumption had went down to what you see today. If you are also experiencing the same problem this could help. I would suggest doing that. I would never recommend using bioses for situations like this so it really serves no purpose at this time. Which draws me to ask if you used or alter the bios in the past?Quote:

Better yet just create a 2D profile, add the icon to the desk top and click on it and see if that stops the 2D-3D switching.
I got powercolour 4890 I think it has a shutdown vrm temp at 95-110*c. I notice some people are doing over 125*c in vrm. Has anyone got 1000mhz/1200mhz bios try to update the bios seem if the vrm temp limit is gone?

Eastcoasthandle
yes that is what i'm using and sorry but i don't have a camera to take any photos :(
i don't want to remove the heatsink because i have no paste to reapply and from what i have read the heatsink comes all off in one piece exposing the core and memory and than you have to remove the plastic to expose the actual part where the dirt gets in .
also i don't want my screwdriver to leave any marks on the screws because the shop could say that i messed with the card
i closed all the applications i could and that didn't stop the 2d/3d switching :(
please dude give me your bios i know how to use RBE to look in it so i can spot the differences ,ATIWinflash to flash it if i decide to and if something goes wrong i can make a autoflash disk using atiflash360 to unbrick it from dos or use a second card to flash the first one :D

Did you provide a pic of your video card? I like to see what it looks like.
I can assure you it's not the bios. I just ran the GPU test again and got this:Quote:

I thought about it and wanted to know if I was averaging 55A. So far it's not. I honestly think you should get yourself some TIM, open up the HSF and clean out any dust that may have accumulated in/near the vrm area.
I think he has flashed it before yes because I had that same issue when trying to mod my BIOS back in the day when I first got the one I think is causing issues and it did exactly this, the whole switching from 2d to 3d crap. I ended up finding a BIOS for a reference card that was clocked higher and flashed them both to it and the issue went away.Quote:

Maybe PM him and tell him exactly how you flashed the bios, etc? Because you and I don't have the 2D/3D switching problem. It's a thought...Quote:

I mean this in the neutral way, but before you say 'it could happen', you should undertake a much deeper understanding of the GPU, the code that runs on it, and the parallels it draws to OCCT's code.Quote:
