Graphics Cards OCing

Recommended Posts

So I wanted to get into overclocking my graphics card to see what I could get up to in terms of stable OCs. Watched some vids on youtube and decided to try it out. I have a EVGA GTX 660 with the reference design cooler and stock clocks (not OCed or SCed from factory). Here are my reuslts so far:

I wanted to know what you guys were getting in terms of OCing with specifically the GTX 660, if you guys have it... Can I get it higher? If you guys see me doing something wrong I'm all ears for some pointers as this is my first time.

 

Note: Since this is the internet, everybody's gonna scrutinize the photo, so before anyone says it/points it out: yes I have a 3570k and no it is not OCed yet. Just haven't had the time to do it since it can take a while to get it right so please lets try to focus on the graphics card first please.

 

Thank you for your time.

I've never done any serious OC myself, only minor things.

 

How hot can you get a GFX card (I have a 550Ti) before you start to worry about temp? I usually just do small increases and test it with something that makes my GPU sweat, and stop when the graphics start to glitch out. Never gone above 60°C.

Although I don't have the time to give you a large overview. I have seen that card at around the clock you have it now. That is pretty standard for reference models, and should be just under the boost clock. I would disable the boost and find a slightly higher clock that it is stable with. 

 

Purchase, or run a bench-marking program. I use 3D Mark myself. Make a small +/- clock adjustment and then run the test. Monitor the temp and performance gains. Rinse and repeat until it becomes too hot for your liking, or you crash the graphics drivers. Dial it back to find a happy medium. 

 

Heaven benchmark (http://unigine.com/products/heaven/) is also a very popular option used by the guys at overclock.net for their top 50 rig list.

 

I had mine in the top 25 for a period :)

Nice, well the GTX 660s temp ceiling is around 80ºC, anything higher than that and I should start worrying. I fixed the fan curve before overclocking and I haven't gotten it past 80ºC. I guess I could try to push it some more, don't know how to disable the boost though.

I too have a 550ti :D

Before you start OCing make sure your PSU is suitable. If you re not sure about that -

 

Pls list all components of your PC: GPU, CPU, RAM, HDDs (mechanical), (H2O Cooling powered by PSU?) and most important the PSU model!

Ok - PSU should be able able to handle your system with OC incl. raised voltages on CPU + GPU.
