Artifacts

By UOAlien

  1. I've read quite a few articles on here and on the net in general trying to figure this problem out...Now I'm just needing some clarification on my specific setup.
    I have an eVGA 8800GT that has started showing artifacts or outright freezing the computer during Fallout 3 (and other intensive games). It really started happening after installing Fallout 3, and now it seems to crash in other games more often.
    My PSU is a Rosewill RX950 which states it has 4 +12V rails at 20amps. When I run SpeedFan (or Everest) I get these results:
    Vcore: 1.13V
    +12V: 10.67V
    AVcc: 3.31V
    I assume that is reading 10.67 amps going to my graphics? I've tried both 6-pin connectors to make sure and both show the same value.

    I've monitored the temps while playing Fallout 3, and with the fan at 100%, they never got over 45 C, which eliminates overheating.
    I've uninstalled, cleaned and reinstalled graphics drivers.
    I've underclocked the graphics, both memory and core/shader (shader clock was linked to core clock).

    So, my questions are these:
    Am I reading SpeedFan correctly?
    If so, does that mean my PSU is not pumping out what it says it should be?
    If so, is there a way to fix it, or do I have to get a new one (or RMA)?
    If so, what would people recommend? I have a RAIDMAX Volcano in another computer that I might be able to use if I can find my 6-pin connector.
    Could there be any other reasons for the crashing and/or artifacting?

    As I am not above 5 posts, I cannot add links to my post, so you will have to copy/paste from below and add to newegg.com to see the products I have:

    That 10.67V means volts not amps. Your 12 volt reading is low. Replace the Rosewill power supply ASAP!
