I am new to OCing and have 2 GT 545s in SLI configuration. The Default clock for the core/mem is 720/900. I have OC'd them using Afterburner and set them currently to 850/950 and have them running air cooled. I don't think that it is an unsafe OC however as I mentioned I am new to this. I would like to set them higher if possible with out causing damage to the cards and still being air cooled also. I am hoping that some people can help me with this and help me find a safe air cooled OC.

Thanks in advance to any and all who have some advice or help to give.
