32 bit only deters the amount of RAM that you can use at once, which is 3.6. And in the BIOS, there are options to increase output voltage and CPU clock speed, those are your overclocking options. Bumping the processor from 3 GHz to 3.5 wont necessarily need a voltage increase though.
Thanks, I just wondering if anyone knew the settings to overclock my CPU. I knew there where limiting factors for a 32-bit system but I was not sure what they where, thanks for clearing that up!
