I created a new account in the hopes of helping someone.My old one just doesn't want to work for some reason.Ok so....
I have a MSI 560 TI Twin Frozr.Soon as i bought the card the issue started,was not happening on the 260 i had. First i tried drivers,no luck.Then i tried setting the power mode just for Firefox from adaptive to performance.No luck issue still occurring.I then set the global setting to maximum performance so the card was always running at full speed 3D clocks.Seemed to get a little better but could have been luck. To help rule out the card being bad(bad memory or gpu) i ran the OCCT gpu test with error checking on for 3 hours. I then ran a Cuda based memory test for 10 passes.Card checked out fine.
Then i bumped up the voltage with MSI Afterburner by .15.Bingo...issue fixed
.I literally cant make it TDR now, i could on command previous by spamming Firefox.exe or Tabs.
I am not saying this is a fix for every vendors 560TI.But i am saying that in some instances, especially with factory OCed(and possibly self oc'ed) cards such as my 560 Twin Frozr,it may help.As they are factory OC cards, i think the voltage they set them at isn't enough for some that leave the factory.Personally i think this is slipping through MSI cause they are not checking stability at 2D voltages and temps possibly?I have seen the same issue with some Sandy Bridge chips/motherboards.Fine when loaded but crash during idle.Alot of times cause the mobo is set to Auto,or people are setting it themselves but too low of an idle voltage.
I also did see a thread afterwards where another MSI 560ti owner got the same result after bumping the voltage.I think this might be a small percentage of the TDR issue as they cant all be voltage lol.For $hits and giggles it would be interesting if everyone above bumped their GPU voltage by .10 or .15 for a few days and see if this helped other Nvidia cards for testing purposes assuming your comfortable with it/and kept your eye on the temps just to be safe,assuming your card is equipped to have the voltage bumped.I don't think all of them are capable of it.I don't think anything in the 5 series would be affected much temp wise personally as they tend to not run as hot as the 4 series,but still.If you use MSI Afterburner to do this make sure you check the "apply overclocking at system start up" button at the bottom or the voltage change will be back at default every reboot.
Edit***I should clarify me bumping the full power 3d voltage and it fixing the issue makes zero sense.My TDR's occur in low and middle power states,what you see during browsing without flash.I cant explain it.
Edit** Here is the link for the Cuda Memtest,not a bad idea for ones toolbox for Nvidia cards. http://www.softpedia.com/get/Tweak/Memo ... Test.shtml
Edit2* Hmm,it seems that might have been written by the same person that wrote OCCT,so its possible this is actually what is used during the gpu memtest within OCCT.Great program to for burn ins to check for errors for those not familiar with it.ALWAYS keep an eye on the displayed temps for a few mins when running OCCT to get a feel how how its going to run your gpu/cpu before walking away from it for a while.It idles for 1 min after you hit start before it does its thing.Of course you can set the idle to zero if you wish.Also,OCCT WILL
stop testing if cpu or gpu temps hit 85c,this also adjustable,but that is a good temp for it to stop at just to be safe.It also stops any time it detects an error.It does the testing 1 thing at a time.Cpu,Cpu with memory check,gpu,or gpu memory testing(if you hit check for errors box).At least thats what i took from it.http://www.ocbase.com/perestroika_en/index.php
