Metro: Last Light has a benchmark in its folder. If you can play it for a few hours without artifacts, crashing, or lower than normal performance. Use any game you have that puts a lot of stress on your GPU. I am not aware of any Prime95/LinX equivalent for GPUs that can somewhat grantee stability after testing. It takes longer due to the games load times, but i have had an easier time finding stable clocks.
I have started mostly using games for stability testing instead. Though not viable for actual stability testing, clocks that seems stable in Valley might not actually work in other applications. Unigine Valley is good for just quickly testing clock speeds (it will crash if bad overclock in my experience). Most of the time overclocks seem stable when testing, but when i launch an actual game it crashes or there are artifacts. wow so just stick with heaven then.Kombustor and Heaven seem to have mixed results in my experience. Not a big one, but large enough that it needs to be talked about.ĭO NOT USE FURMARK. A quick google and you will see that this is an issue. But for a small percentage of people, Furmark has broken their card, including myself. If your cooling cannot keep up with this excessive heat and load applied to the GPU, or there was a bad solder job done at the factory, or any number of things related to power delivery, that is when Furmark has the potential to break or degrade your GPU.įor most people, Furmark doesn't do anything to their GPU. I understand why reviewers use it, to get a worst case scenario idea, but it is so far outside the real of realism, that it should not be considered.
#MSI KOMBUSTOR VS HEAVEN FULL#
A pedal to the metal, push the car/GPU as hard as it can possibly go in a straight line, no turning, no stopping, just full on, all out go, go, GO! In a realistic scenario of GPU use, you would never, ever do this. Now, what furmark does is not like a game, or a Nascar race. You speed up, you slow down, you turn, you pit stop, things are going on that your car has to adapt to similar to your GPU when you game. When you are racing, your car is always adapting to the situation around you. Think of a Nascar Race, imagine the car as your GPU. When something demanding does happen, then the GPU will ramp up to meet that demand. It isn't going to use excessive amounts of power on a loading screen, or a cut scene, or something non-demanding. Depending on the action, or lack thereof that is going on in game, the GPU adapts to that scenario. When you are gaming, changes are going on in the game, your GPU is basically using "adaptive mode" similar to your CPU. This next piece if not just for you, but for everyone because I think this is the best analogy I have ever heard that describes what Furmark does. It is much more comparable to an in-game scenario rather than the pedal to the metal that Furmark is. Heaven is very demanding.Įxactly, Ultra everything on Heaven for 15-20min is an excellent stability and heat test. If you are just on air I´d go so far and say don´t crank up the resolution in Heaven a lot because it is likley that your GPU runs into thermal throttling. And completely not necessary when you have stability stress test like you pointed out with Heaven or Valley. Furmark is IMHO crap, you would need very good VRM and watercooling to stress test the GPU without risk.
