Hi, I've been trying to figure out a way to get a bit more power out of my very out dated machine. I've got a Intel i3-4130 CPU @3.4ghz, with 16 gigs of ram and gtx 645. I've been doing some reading and I've discovered that I can over clock my gpu. Seeing as how I'm disabled and can't afford to upgrade any components at the present time this seems like a viable solution. The only problem is that I've never done anything like this. I'm curious if there's a standard amount I can safely over clock it? I'm using MSI Afterburner as my overclcoking program.

The GTX645 is an OEM variant of the GTX660. It seems likely it's restricted for overclocking, possibly because of that. Many cores are turned off to achieve the 65W power requirement.

Given the numerous superior alternatives, I question whether significant overclocking has been performed on this card at all, if any exists.
I wish someone could provide a more helpful response, but that's what it appears to be.
