DO: set your "post per page" to 60. Only 23 pages.
DO: be methodical in your overclocking. Keep records.
DON'T: increase voltages "to be safe". An overvoltage will make things as unstable as an undervoltage.
DON'T: accidentally set the CPU Voltage Offset. It adds 0.3v.
DON'T: set memory timings too loose. Again can cause instability.
DO: use the calculator in my sig to see what's going on at different ratios, speeds and multipliers.

No vmods needed or available.
Drivers depends on OS. For Vista, you don't NEED to install any but you can.
If you do, install the chipset drivers first.
Update to BIOS 1554 and turn the watchdog off.
