Re: Overclocking GTX 460
It's really easy with Afterburner. Just adjust the core clock and the shader clock automatically adjusts so it stays in a 2:1 ratio. You should be able start at 800 core with the stock voltage. From there, I increased by 25 MHz each time until 900 MHz was not stable at 1.0v. Then I decreased by 5 MHz until it was stable. 885 MHz was stable for me, so I use 880 to be safe.
I have no idea how much the memory clock should be increased, that's why I posted this topic, but I am sure of the core clock. I know once you find the max stable core, you should then increase the memory. The memory clock on my card seemed to be stable at 2190, but I don't know if that's safe, so I just set it to 2100 MHz.
I use Furmark to test initial stability (run for 5 mins after each increase). Once the core is maxed out, then run furmark for 30 mins. After that, I usually run 3dmark a couple times to make sure it's stable. Games are also a good indicator.
You can OC this card a ton. It's basically just how comfortable you are with high clocks for 24/7 use. I have a limit of 70*C for all of my hardware that I OC (CPU/GPU) when stability testing. That way, when I play games, it doesn't go anywhere near that high.
I think I'm done tweaking my card.
Volts: 1.0v (0.962 stock)
Core: 880 MHz
Memory: 1050 MHz (2100)
Shader: 1760 MHz
It's pretty quick with those settings. I'm not one to push things to their absolute maximum. I didn't want to go above 1.0v, but a lot of people just max out the voltage in Afterburner, which is around 1.1v.
Hope this helps.
