When overclocking, you should be careful not to corrupt any files or programs on your hard disk. Your CPU overclock from 2.66 to 3.0 on a E7xxx Intel is somewhat conservative and should run at that speed without a voltage boost. You may be able to reach those memory speeds but you might need to increase your memory timings quite a bit.
First make sure your PCI bus is locked @ 33.33 Mhz. Also the PCIe is at 100 Mhz.
From there you can start increasing the CPU and memory speeds via the FSB, but you need to use programs that test for system stability.
You should test your memory stability first outside of the windows environment so that your don’t mess up your windows install. Memtest can be downloaded as a bootable CD here: http://www.memtest.org/
You can let memtest run for a few hours to ensure your memory is stable at your settings.
For stressing the CPU and Memory in Windows use this program, IntelBurnTest.
It is an extremely stressful program that you will not have to run for 24 hours to ensure stability.
