If it hangs, then I guess your motherboard doesn't support overclocking. If you really want to overclock, get a good mobo like DFI, MSI, ASUS etc. These boards are good for overclocking. I've overclocked my CPU by 350 MHz, just by increasing the FSB by 37 MHz. It's the MSI K8N Neo3 board

Try raising your latency timings of your memory. Try it running 3-3-3-8 and use 2T timings.
