GPU Overclocking - Stability Test

[Coollok100]

Hi Guys,

I recently tried overclocking my graphics card, gradually increasing the core clock and memory. In order to test for stability I was using Furmark. I got to a level where there was no artifacting, and would run stably for hours (I tested for 4 hours, it was running at about 20fps, max temps were 76 degrees C). Anyway, I noticed when this was happening that my GPU was not boosting at all, the core clock was stuck at 979mhz, and would stay there no matter what. Having decided that my overclock was stable, I continued to start playing some games. However, they all crashed after about 10 minutes of game time. As such I have backed off my overclock, and it is all stable now, but it makes me question how effective Furmark is as a stability test, and what I should use in future.

Furmark sucks. The gpu clocks itself down on those giant loads, which are totally out of the normal range of load. For stability you should just run a few minutes of gameplay and see how it goes, at least this is what im doing.

Personally, when OCing, I just play a game.

Even for cpu OCing I find games will freeze up even though p95 pass 24hrs of testing.. The best test for me when I oc my gpus is I play crysis 3 for a couple hrs..

You may like OCCT for a stability test..It tests the whole system.

3dmark and unigen work better as stability for me than burn tests. If it runs through those fine. It's usually stable in my experience. Just loop them for a while and see.

Hey I have been overclocking my GPU recently too, and I found that on one day, I get a Score of 1587 stock and up to 1654 after OCing, but the next day I get 1581 on the same overclock. WTF! (1080p, 4xMSAA) 

If somebody could explain this other than "FurMark sucks" that'd be great.
