Overclocking a 680m

So, having seen HTWingNut's performance thread on the 680m, it seems like you can easily get an extra 20% performance with some mild overclocking.

I run MSI Afterburner for FPS measuring and am tempted to OC the card. I was just wondering if others found it worthwhile to do so. I know that every card is different and so I might not be able to make the same sort of gains as someone else's machine, but I only ever tried overclocking once (my old 285m rig) and the benefits to that were so minimal and the heat increase large enough that it put me off the idea.

 

The 680m is said to be very OC friendly. It's good that you came to get input on the matter though; you wouldn't want to get over zealous with it and consequently ruin an excellent card. Often enough, 5% - 10% is considered safe, although personally, I don't recommend OC'ing - even in desktops, where there is better heat dissipation - as it's always liable to cause instability. But many end users overclock and never have an issue.

 

If you start slow and gradually increase your clocks by a couple percent you should be safe. Don't overvolt, watch your temps closely, and you will be fine
