Nvidia TDR problem **possible fix!**

I was having a nightmare with this on a 5870. Was getting it at the desktop all the time. It was odd though as I would get the lock up with vertical lines, of varying colours each time. Sometimes shades of grey, sometime thick white with thin black, sometimes multi coloured.

Every now and again, if I was lucky and if I was quick enough to take my hands of the mouse and keyboard, it would manage to reset the driver and get me running again. But always with corruption, which I'd need to reboot to clear.

Now I was, and still am to an extent convinced this is a software issue probably an update to Windows but have never really got to the bottom of it. But where it got really odd for me is that quite often once it had happened it I would then have trouble booting, even posting BIOS.

I'd quite often have to pull the power for 10/20 mins to get it to post then boot normally. Some nights I' have to go through this procedure multiple times before it finally became stable. Once I'd got it into windows and it managed to stay up past about 20 mins it would be fine after that. I could game etc with out issue and the PC would be stable for days on end. Until I had to reboot it again and then it could start over.

I still think it is software related somehow but what seems to have improved things for me, after trying various other things, was to loosen the timings on my ram. Or rather, rather than setting them manually to what they can and should run at I set them in BIOS to use SPD, the timings on which default slightly lower.

Seems to be a lot better for me now, so have given up trying to get to the bottom of it. Just need this PC to last me a few more weeks until my new build is planned.
 
Just to confirm what others have said this is not a fix it is a workaround and if windows is told not to restart the graphics driver and the driver has stalled most likely a BSOD will follow.

The only possibility of it really helping is if the driver is stalled for only a short period of time and increasing the TDR timeout gives it enough time to recover (unlikely).

My understanding is there are two distinct TDR scenarios:
1) Affects mainly GTX460/GTX560ti users and is an manufacturing issue with the graphics card hardware and is a voltage problem with the hardware and not much users can do about it.
2) An issue with a users hardware as a whole maybe o/c or heat related including a fault with the specific graphics card which needs to be addressed by the user.

I spent a bit of time trouble-shooting this last year and started a long thread about scenario one on the nVidia forums, last time I looked it had over 1 million views and 100 replies. Unfortunately no fix was forthcoming from nVidia. I have a system that was totally stable with an HD5850 and then had TDR's with a GTX560ti (and also with a GTX460 I borrowed to test) but totally stable with GTX580 o/c to 900Mhz. I suspected that upping all voltages on the card bios might fix the problem using NiBiTor v6.03 but whilst waiting for a fix from nVidia I gave up and switched to the GTX580 as I got one at a great price. The GTX560ti is in a friends PC and he has an occasional TDR's if he uses any drivers more recent that 275.33 and he has tried everything including under-clocking the card.

I had this problem in the past few days on my m17x with a nvidia gt 560 gpu. I fixed it by removing the gpu clearing the fans and re sinking and reseating the card. I know there are many other reasons why this happens, but this worked for me. Worth a shot if you're having this problem.
 
I may have the sollution - at least a possible one!

Hi,
I work as a Systems Integrator, assembling many different types o industrial and military PC's, but I hate having home pc problems. I have home network of three PC's - I love em missus hates PC generally. I have two Q6600 based servers (both with Nvidia cards - one a TV media streamer attached via HDMI to a Samsung Smart TV and a File server - my main PC is a (I Though) lovely I7 3770k (at stock 3.9 GHz) and 16 GB RAM - a GTX 560 TI (from Asus), and an OCZ 700W Modtream to keep it all chugging along, but I Have had nothing but TRD's and Black / BSOD's and the like, especially since installing the series 3xxx drivers - I just (really frustrated but not wanting to throw money at the problem) re-installed the 2.67 driver provided by ASUS on the OEM CD, and it seems to be OK - of course time will tell. I also read that too much RAM might cause the problem, so may have to remove 2 sticks of my 4 to see, but fingers crossed, I might have the fix. Here is a link to my drivers. you should be able to search Nvidia site if this doesn't work. https://dl.dropbox.com/u/37087312/Graphics NV Drivers.rar Hope you & thousands of others get this resolved soon too.
 
Weird that this thread should be bumped now. I never did fully get to the bottom of my issues (see old post above) and after going to my new build with a 7970 tried the old 5870 in my nephews PC, only for him to get the same issues so ended up taking it out.

Reason the timing on this bump is weird as I've just put the 5870 back into his PC this weekend, as I want rid of it, so will see if this is still an issue with it.
 
I'd bet that about most TDR's will be unstable pre-overclocked cards, the driver naturally needs to recover the GPU when it falls over.
