That's a lot of questions Josh but since you're takin' care of business for us in Iraq, we're more than happy to oblige. You're correct, that program is CPU-Z a processor, motherboard and memory monitoring and diagnostics tool that we use all the time here.
Also, you can most likely overclock that QX6700 to 3GHz with little or no voltage boosts in your motherboard BIOS. To get 3.33GHz we needed to bump core voltages to 1.5V. Linkboost is an NVIDIA chipset-based overclocking technology that allows for an immediate 25% increase in the speed of the HyperTransport links that connect the SPP Southbridge and MCP Northbridge chipsets, if an NVIDIA graphics card is being used. By the way, NVIDIA has since removed this feature from the 680i chipset, though we're not exactly sure why.
Finally, like overclocking your processor, overclocking your memory is almost an art-form of sorts. In the BIOS, try changing memory divisor settings in conjunction with FSB settings to dial in on faster combinations of both memory and processor speeds. Depending on what speeds your RAM is rated for, you could be able to hit speeds of 1066MHz or so but you might also need to relax DRAM timings as well to get there. If you go too far beyond the specs of your memory, you'll need a bit more voltage. Most performance type DDR2 memory, like your OCZ sticks, will tolerate 2.1 - 2.3V or so without too much trouble. Just keep the airflow moving inside that chasis.
