I have a Galaxy GT 240 512Mb DD3 non-oc'ed reference card. I used MSI Afterburner to get my card to 690 core, 1681 shader, and 1020 mem stable at 1.050v and 6 hours of MSI Kombuster. I start to get artifacts if I OC the mem or shaders/core any more. What I want to know is, what is an average overclock for a GT240? MY core clock is overclocked 26%, the shader around 27%, and the memory 12%. How much of an overclock is that? Thanks.
Oh, I did some Googleing and found out that most graphics cards have a default voltage of 1.050v. And I couldn't adjust the voltage on Afterburner, since the GT 240 has a maximum 75W intake from the motherboard.
