7990 on it's way out?

2D clocks/volts? What's that?

GPUs have two speed settings, one for when only low power is needed (at idle and when doing 2D stuff ) and one at full speed (for doing heavy graphics application, like a 3D game).


The GPU automatically swaps between each state as needed, unless you tell the card to use it's fast speeds all the time. Sometimes, the Low setting needs upping a bit if the card is crashing during idle, or 2D applications... Sometimes a game will use the low settings during the 2D parts of the game, menus etc.


You can change all this in afterburner,

With this you can try setting your 2D clocks speeds and volts to the same speed as your 3D clock speeds and volts. See if that cures the problem, then reduce your 2D clocks and volts to somewhere inbetween that you are happy with.


Could also be your cards memory, try underclock just that, by like 150/250 or something.

It's odd but I can't find that option in my afterburner. I have the latest beta version...

Also as I am running on stock settings on the gfx card but underclocking, even slightly am I not doing something I shouldn't have to do? I mean the card should operate at stock speeds fine. It always has.
 
In afterburner, 1st click reset to go back to stock.

Then save them as profile 1.

Now go into settings > Profiles tab.


Under 'Automatic profiles management' choose 'profile 1' for each of the 2d and 3d settings.
 
It is missing if you don't install RTSS when you install afterburner, reinstall and do install riva statistics at the same time when prompted..
 
when you undervolt, you could also drop the core/ mem to a ``Miners`` set up, about 1.09.........900..........1422
but this will not effect what's going wrong here..........you need to try another PSU in there.

if it's the same then the GPU is knackered out............buy a PSU that's powerful enough for a fresh rebuild, do not risk 750W on a top end AMD dual card again...........only 1000W, because this will give you a bit of breathing space

so like everything else PC related it's gonna cost a lot of money

Does the PSU have four PCIE cables? if so use one from each set/pair i had a issue with my 7990 using the two built in PCIE and had to use a modular one and one built in otherwise it would randomly crash.

aaah yes i've heard of this before
 
So coming back to this after a few days of not giving the card an good session...

So I thought I would give the card a bit more stress, I ran a futuremark 1080p test (1920x1080 resolution my monitor) after 6-7 minutes of the temps staying reasonable and the FPS being at 115ish all of a sudden the temps went up to 101C and the FPS could not get above 60.

I then immediately booted up Heaven 4.0 and the struggle was clear, I got a score of 965, earlier before I got 1700+, I also ran GPU-z and it said on one of the GPU's the core clock didn't get above 500mhz.

So it seems the card runs seemingly fine for a period, it's been good for 45mins to an hour in the past but something happens and the card can't cope with all the graphical shenanigans going on.

Does this sound familiar to issues you have experienced with other cards? Just for my own piece of mind that it is the card.
 
So I am RMA'ing this Monday.

If I get a replacement, bearing in mind the card was £500 when purchased what is a fair replacement for performance? Would not mind switching to a 780TI GTX to be honest.
 
This has gone for RMA,

now the likely wait for overclockers to test it and then 28 days MSI will have for testing and to resolve my issues.

Does anyone know how good MSI's RMA procedure is?
