These are my components that I have E6750, p5n32-e sli plus, OCZ DDR2 PC2-6400 Reaper HPC 2GB Edition x2, cooler master 550 watt power supply, 2x Seagate sata 150 gig hard drives, and DVD r-w. My problem is I can’t over clock this thing at all I have read countless things to try on the internet but no luck. All I want is to get 3.2 GHz out of the CPU. I have tried over clocking it many different ways. I can get it to boot into vista it loads everything up then locks up. Some one please help I need to know what to do next I know this motherboard is not the greatest but replacing it is not something that I want to do at the moment. I think it is something to do with the memory but I don’t know I would be willing to replace it. I’m also interested in get some SLI memory what do you think that would do for it?
