Max VID is 1.3625 volts. That is the maximum voltage that the CPU chip will program the motherboard power regulator to produce.
Intel's max recommended voltage for the 45 nm Core2 Cpu's is 1.45 volts. That is not the same thing.
Here's where the "1.45 volts" figure comes from.http://download.intel.com/design/processor/datashts/320467.pdf
You can learn all kinds of neat things poking about the technical documentation.
badoosh, forget the RAM overclocking on a Core2 system.
I am unfamiliar with Asrock motherboards, but he is what you need to do ...
Download and run CPU-Z. It will monitor your RAM settings. You want a 1:1 FSB:RAM ratio.
Go back to stock settings, then adjust the RAM frequency to twice the FSB freq. FSB will be 333 MHz. RAM will be running at 667 MHz. Now start pushing FSB and core voltages up. You should easily reach 3.3 - 3.4 GHz. If you have an E0 stepping CPU, you should be able to reach 3.5 - 3.6 GHz.
