GTX 580 SLi OC Stress Tests

post #1 of 24
Thread Starter 
I am currently stress testing with Kombuster which was provided with my video cards. I was wondering how long I should be testing these runs for, and also I noticed that only GPU 1 is being stressed to 99%. How do I make sure both of the cards are tested properly? Thanks!

Most say run it for 15-20 minutes while looking for artifacts. Then go play some games.

There should be a shortcut in the install folder that says Multi-GPU client on it I think.

I know Furmark has a separate multi-gpu client. Kombuster is just MSI's version of Furmark (same program, but with different interfaces). I would say give Furmark a try.

In addition to stability testing with things like Furmark or Kombustor I would also make sure to test with things that more accurately simulate the load of a real game, like Unigine Heaven, 3DMark11, the Crysis Benchmark tool, or finally just playing your favorite games. The are two reasons for doing this, first off with the 500 series Nvidia has implemented something called Over Current Protection that detects programs that Nvidia deems "power virus's" like OCCT GPU test, Furmark, and Kombuster, and throttles the clocks down on your card so you are not seeing an accurate stress of your card. Secondly, things like Furmark are designed to first and foremost just pull massive amounts of power, which is good for testing some aspects of a card's stability but it does not accurately simulate the load a real game creates, so you can have a situation where a OC is stable for a long time through Furmark but will fail in a game.

Yup, programs like Furmark are great for testing things like max power consumption, heat, etc. When it comes to stability, however, it's OK to run Furmark-like programs for a few minutes to test, but the best stress test for GPUs is actual gaming.

seems like it is a visual bug with the game. i wouldn't worry

"-Visual bug: Textures of background trees have white dots on them, but only at medium/low graphics settings, not on high. (I have Nvidia 7900GT with latest drivers, no overheating)."

I can't remember the specific thread I can confirm that someone else on here was having the same white dots under trees in Crysis.
