More about gtx 660 crashing
  1. What make/model is your power supply? Is Windows fully updated and are your drivers current?

    What are you CPU and GPU temperatures at idle and under load (like when gaming)?
  2. my PSU is 480W and all the info I have got from it is this: Power Supply: 480Watt Stand Power Supply
  3. It really sounds your power supply is not providing sufficient power to the system. Did you look at the label on the side of the PSU (you would have to open the case) for the info?
  4. GPU idle: 42C but I can change fan speed
    CPU idle:38C

    GPU load: Around the 50C (I can speed up my fan)
    CPU load: 50C-55C
  5. I've already opened up my case to look for the brand and everything for it, but it doesnt say. its just a big black box
  6. Did you build this system yourself or buy one of the shelf?
  7. I bought it built but ive replaced parts in it. Also my CPU squeals when in game so I think that is a lack of power in the coils around it, but I also OC it and Ive tried to make it stable
  8. Ill tell you my settings in BIOS if you need it, also I would like help on OC it because I've tried everything
  9. and also is my RAM speed okay?
  10. Set everything (CPU, GPU, and memory to stock speeds until the system is stable. You have to work from a solid baseline before you troubleshoot the system.
  11. well its stable at stock but it still makes the nooise no matter what, but ill go to stock let me restart my PC
  12. what should I set my bios settings at
  13. Settings for CPU and memory should be at the default AUTO settings. Then bot the system and make sure the GPU is set to stock as well. If you change the GPU settings, restart the system afterward.

    With everything at stock, fire up a game and you temperature monitor application and play for a bit. What temps are you getting up to.

    If all is well after some extended playtime, you can try tweaking your CPU and GPU. Only work on them one at a time. Make small changes and test for stability after each change.
  14. my CPU is now at 48C with default settings. what about my ram? can i increase that?
  15. Don't OC your RAM (I never recommend it). OCing memory can lead to all sorts of stability issues. Besides, the gains are minimal. Stability is more important. You also get much larger gains from OCing your CPU and GPU. So, just leave the memory at AUTO and focus on the CPU and GPU.
  16. is it ok if i OC my HT width to 16bit? and what would you think my speed should be?
  17. Check this link for multiple suggestions:

    What heatsink are you using?

    Personally, I would just tweak the clock multiplier, if you aren't comfortable adjusting the other settings.
  18. I'm using the Heatsink it came with. in that case, its air cooled
  19. I don't recommend OCing with the stock (a.k.a. OEM) heatsink. Those really aren't designed to handle the additional heat that gets generated by OCing. You should use an aftermarket heatsink (like the Cooler Master 212 EVO that many folks use).
  20. I will buy that when I get out of my debt, I currently owe about 300 dollars to someone so yeah. And I think I figured out why it keeps crashing now. The new GeForce Driver that just came out is buggy
  21. Buggy drivers are definitely a pain. Been there. Done that myself.

    I suggest you run at stock CPU and memory (don't mess with that at all) and focus on tweaking your GPU for now.
  22. as has been said start by removing any overclock and test for stability. If its still unstable its probably your psu. What exact brand is your PSU? stick with reputable brands like Antec, Corsair, Seasonic. a cheap 480w psu can often perform like a 300w psu, you could even risk it blowing up and destroying other components with a power spike.
  23. there is no brand to my PSU, it came with my Azza case
  24. I really hate buggy drivers, I am buying a 750W Corsair though soon
  25. problem is I don't have money because i'm in debt 400 right now and working for me is hard in the Winter

    then there is your problem. Get a good brand 500w psu and you will be fine. Stick to corsair, antec, seasonic or xfx and you cant go wrong.

    For a single 660 that would be total overkill, what have you got planned for the future?
  28. I just bought a Corsair 600W with a 12V rail. is that good? it was 65 dollars from Amazon. m
  29. I think my PSU can't stabilize the CPU because it is surging the power to my Graphics Card
  30. Have you installed the new PSU yet?
  31. should be coming tomorrow. Would you think it would improve FPS and performance? Btw, I have coil whining around my CPU right now with my 480W installed so do u think the whining is from lack of power?
  32. A PSU will not improve FPS or performance by itself. It can provide stable power so you can optimize your system (and possibly even overclock it).

    Swap PSUs and then check for coil whine. Good luck!
  33. Well yeah the new PSU will allow stability and overclock
  34. I bought a i5 3570k and gigabyte GU-Z77 UD3H motherboard and with the 600W PSU I run BF3 on Ultra with 60+FPS so I think it was the Processor!
