Asus GTX660Ti DirectCU II OC TDR Problems

For the last several months i have had many problems with my card and tried many things. The problems i am experiencing are i believe commonly related to TDR but may go beyond this.

During games my graphics card will either crash and return causing a black screen for 3-5 seconds, crash and not come back up leaving the last displayed frame on screen, or create a blue screen of death relating to TDR issues.

I have attempted updating all of my drivers and bios, clean install of my gpu drivers,using a different gpu and taking my gpu in to the store i bought it at. the other gpu experienced no problems, the store refused to replace it as they could not find anything wrong with it.

I really don't want to mess around with the voltages and clocks so this is my last hope.

Thanks, Sam

  1. Have you talked to Asus?
  2. I did they told me to take it to the store
  3. If a different Graphics Card worked fine then your card is almost certainly defective.

    It might possibly be your Power Supply but if the other card was a 660Ti or better and worked it's not your Power Supply.

    Not sure why the store says it worked though.

    I'm pretty sure the card is defective but I don't know how to help you further.
  4. The store told me they ran heat/stress tests and ran graphics intensive games for 24 hours. my power supply is a ax750 corsair and it has no faults i can tell all voltages check out
  5. Recently installed the latest patch through geforce experience. no results
  6. Noticed some graphics stuttering/small rapid freezing
  7. Attempting a possible solution from microsoft.http://support.microsoft.com/kb/2665946
    hope it works but it looks like a mask to the problem not an actual solution. regardless it will get me back gaming while i wait for help.
  8. After some testing i have discovered that it only crashes under load and heat, i can play games on low or high graphics but when a lot of stuff starts happening in a scene the crashes start and continue till i give my card a rest
  9. What mobo, CPU, DRAM and in particular what PSU?
  10. Asus p8z77-v pro, 16 gb ram 4 strips gskillz, i7 3770, corsair ax750
    thanks so much for coming
  11. PSU should be good, but might try a different one (if you don't have one might see if you can borrow from a friend to test with)...another possible is DRAM, you show 4x$GB was this a single package you bought or did it come in two different packages, if so may be slight incompatibilities, what is the actual model number(s)
  12. The ram are two packs but exactly the same and i kept them in the right slots one set slots for the package. When the problem started nothing had distinctly changed i hadnt changed any hardware for three months. I will look for the dram model numbers but no promises if i can find them.
  13. G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBXL
    I am fairly sure those are the ones
  14. Might want ot try going to the BIOS and check that the base timings are correct and raisie the DRAM voltage to 1.55 (the sets you have are 1.5....also take a look in the Advanced DRAM timings and let me know what the tRFC is, should prob be around 160-178
  15. Not sure how to check my timings but most of it is set to auto. I changed the dram voltage. Dram REF Cycle timing is 110 not sure if thats what you wanted.
  16. Best answer
    Thay may be part of the problem, the DRAM base timings should be 9-9-9-24, I'd suggest go into BIOS, enable XMP, and select profile 1 for the DRAM, then find DRAM voltage and set to 1.55, save, exit, reboot back to BIOS and see what tRFC (DRAM REF Cycle timing is at, if still at 110, try it at 160)
  17. The base timings were ok, i turned on xmp it defaulted to profile one. the tRFC was at 128 and i could not change it from auto
  18. Just played audio surf 2 and now it smells like toasty silicon in my room. The store i got it from may have lied to me about them not finding problems
  19. Starting to sound like it, try again, and have thenm run something like furmark - it's a video stress test
  20. Would you please run me through a benchmark/stress test? never done one
  21. can download furmark here:

    http://www.ozone3d.net/benchmarks/fur/

    download it, install, then run it, might want an app like GPU Temp running to watch temps, can get that here:

    http://www.gputemp.com/
  22. Do i need to record the temps or does it automatically also should i watch and make sure it dousnt fry my card or does it have failsafes
  23. I ran a number of tests using furmark using Benchmark preset 1080 at resolution 1920x1080. tempetature reached about 74C fps stayed solid at 31. i noticed no visual artifacts or irregularities in the test. got a score of 1883 points
  24. Sounds good - not sure what to think,
  25. Any chance its the cards hardware?
  26. Hard to tell, this is one I'd like to have hands on
  27. I'm at a loss of what to do. i cant rma it because its on warrenty and i cant use the warrenty because they say there is no problem. the problem isnt likely with my computer specifically because there was no hardware or driver change and i cant take them my whole rig either. Is there anything left i can do? is it maybe related to my tRFC being stuck so low?
  28. Managed to get through a long session of Magic the gathering duels of the planeswalkers with no problems so im not sure whats happened. perhaps the ram changes solved it? will take time to be sure. i will be back within a couple of days
  29. Making an effort to push my card as hard as i can to see if it will continue the crashing made it through a number of high graphics intensive gaming sessions with no crashes so far
  30. Sounds stable anyway
  31. The only thing i would see as having changed it would be the dram voltage and cycle timings but why sould that affect the graphics card and why so long after having installed it?

    Intermittent problems can be horrible to troubleshoot.

    Could it be your DDR3 memory?
    Yes. Many errors can relate back to that as that's the data that gets sent to your CPU to run, which then gets forwarded to your graphics card so if you get any errors in that strange things can happen.

    However if you repeatedly get video card specific issues it sounds like the graphics card. Stable for now, but you can try the following:

    1) Confirm DEFAULT CPU and RAM settings (I know you said you did)

    2) run MEMTEST www.memtest.org for at least 10 minutes, but at some point OVERNIGHT

    3) run Prime95

    4) run Prime95 while also running any video benchmark (that's about as stressful and hot as things can get)

    * www.ultimatebootcd.com

    This is an awesome disc image with many tools including Memtest. I haven't tried the VRAM test but it might be worth trying as well. If in doubt of burning app use IMGBURN as it can burn a CD image to DVD which many programs won't due.

    Other:
    Install WINDOWS if the error comes back to a SPARE DRIVE if possible. like this:
    a) Unhook all HDD's and SSD's except for the spare drive
    b) Install Windows, Microsoft Updates, Motherboard Main chipset driver, other drivers etc... but DO. NOT. ACTIVATE. WINDOWS.
    c) Install and run Furmark (no point in trying anything else)

    If the problem starts happening frequently again, but reinstalling Windows solves the issue then it may be a software issue.

    Have you completely eliminated the POWER SUPPLY as a potential problem?
    No.
    For the same reason it could be your video card, it could also be your power supply. An intermittent issue with insufficient or out-of-tolerance power can cause a card to fail.

    It could also be the MOTHERBOARD, but in terms of hardware my MOST likely to LEAST likely is:
    1) Graphics Card
    2) Power Supply
    3) Motherboard

    4) DDR3 memory (memtest is nearly 100% conclusive though).
  33. Well given it even more stress testing still no problems so i believe this to be solved. thanks so much tradesman
  34. No worries, glad all is well, keep in touch ;)
  35. i have the same issues with a jetstream gtx 660 ti , tried everything from changing my power supply to reinstalling windows and the whole crap..
    so far i can only make it run stable by lowering the clock for some odd reason...

    Hi Sam,

    Have you solved the problem?i have the same problem as yours and still has no solution to my Asus GTX660Ti DirectCU II OC. I dont think its a hardware problem. I think its a driver issue.


    Thanks,
