Should i overclock my gtx 580

Thanks in advance for any help! Another thing it seems my cards have high vids. Thats pretty high for idle, mine is. So ya pretty high nongaming voltage. You may not have the best chips but your oc are still pretty good for voltage used. If your games arent crashing with those oc then i would not worry too much about crashing your benchmarks.

Only matters if your summiting scores right. Folding at home may have issues though, cards that show no problems with a oc during gaming OR benchmarking can have issues during folding.

Hi criskoe! I have been overclocking my reference GTX almost one year already, and this is what I discovered. Most likely, your overclock is failing because the VRM mosfets are overheating. After many loops in Heaven or 3D mark 11, mosfets become too hot and shut down or become electrically unstable. One way to cool the mosfets is by cooling the backside of the graphics card, near the mosfet location. I cooled my GTX backside and cpu too by installing a mm fan into my 5.

Warning: many people dont know this but the reference GTX exhausts some hot air inside the case. With my old case, there were no holes to exhaust this hot air and the whole rear side of the case became hot. With my current case, there are small holes in the back which allow hot air to exit.

To allow even more hot air to exit, I also removed the two black rubber grommets at the bottom of my case see second photo. Another suggestion Even if gpu temps are low, VRM mosfet temps may be high especially during stress tests. A little less voltage may help to lower mosfet temps. Or increase fan speed even if gpu temp is low. Fans are for cooling the gpu and also help cool the VRM's and other components.

Thanks so much for the suggestions. I really appreciate them. But I dont think cooling is my problem cause all the fans in my pc are high cfm and rpm fans hooked up to a fan controller, and when im stressing i have them all on max Next step would have to be full water cooling loops for them : From other posts in other forums it seems its alot harder to oc 2 cards in a system then one However, with skyrim.

Clock speed on your GPU does little. You'd be better off over clocking your CPU for the time being to improve frame rate in that game. Although, a single should run that game fine. Maxed out at P with 2x AA you should never drift below 35 fps. That game is very poorly optimized to utilize powerful GPUs. DelroyMonjo Distinguished. Mar 18, 2, 0 21, Thanks Delroy, that was a good read. I don't think I would want to push the card that hard without an effective cooling system.

Anyone have personal experience with this card? Frizzo Distinguished. Sep 17, 0 19, 8. Thanks Frizzo, I think maybe it's too risky to hardcore overclock this card with my current setup.

It was a substatial investment for my work and I need to make some dough out of the upgrade before it gets fried, lol! At the very least, I have discovered how to manually adjust the fan speed which is pretty useful when things start to heat up. Thanks to you both for your help but for now I think I leave boosting the voltages to the enthusiasts.

DelroyMonjo :. Show me a repeatable benchmark which isn't synthetic. What can be learned from the review is: how much can I OC? If a 3 or 4 minute benchmark was available for BF3, I'd run it. But game developers aren't going to let that happen, Just look at the min and recommended platform requirements for recent games. Tom's doesn't care for Unigine as a benchmark, synthetic ya' know.

But if I want to see how my video card reacts to OC'ing and the heat parameters, that's what I use. You can use anything you want, I choose to use a repeatable benchmark. That was completely irrelevant to the subject. I simply used the latest GPU-Z 0. To detect artifacts with OC Scanner, I recommend to enable the heavy mode, in the settings box:. Okay OC Scanner is ready for artifacts scanning. Press the Start stress test button and you should see this rendering:. In short, as long as all values are 0, that means you overclocking is stable.

As soon as one value is greater than 0, your overclocking settings are too high:. It sounds hard, but it really can be done in less than a few minutes. Example: If your card runs at MHz which is pretty common these days then I suggest that you don't increase the frequency any higher than 30 to 50 MHz.

More advanced users push the frequency often way higher. Usually when your 3D graphics start to show artifacts such as white dots "snow" , you should back down MHz and leave it at that. Usually when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. Carefully find that limit and then back down at least 20 MHz from the moment you notice an artifact. Look carefully and observe well.
