I have an Alienware M17x R4 with a 660M and I'd like to overclock it beyond the limits Nvidia set on it. Currently with MSI Afterburner I can only set it to +135 on the core and I've read that the 660M can clock higher even with stock voltages. In my case however I'd like the limits to be removed and a slight bump in voltage since the cooling on the M17x R4 is surely overkill for a tiny 660M, I mean I'm running +135 Core and +400 RAM right now and the average temps while game is just 60c while sitting on a desk not elevated, so I think it can surely handle more. A quick search around didn't really reveal anything useful on how to modify the vBIOS on the card, but I did find a post on another forum that had pre-modified vBIOS for a 660M but I'm not sure if that would work for me. Any input would be appreciated.
