[Question] Some basic questions from a beginner

[xenova]

I'm new to OC'ing and just want to ask a few questions:

1) Increasing the OC multiplier by 1 will make my cpu run how much % faster?

2) I don't understand under what circumstances I have to increase or decrease offset voltage and by what intervals I should increase/decrease it by. I see some people increasing it when they reach an unstable point whereas others purposely go into negative voltages. What's up with that?


Currently using i5-3750k and ASUS P8Z77-V LX mobo

help is appreciated!

The speed of your cpu is the fsb x multiplier the stock fsb on the i5 is 100mhz so everytime you raise the multiplier you raise the cpu speed 100mhz, stock speed of the i5 3570k is 3400mhz(3.4ghz) so divided by 100 is 34mhz is 1% so roughly speaking raising the multiplier by 1 is increasing the speed 3%,
Don't mess with the voltage if you don't know what your doing, read this guide http://www.tomshardware.co.uk/forum/265056-11-2600k-2500k-overclocking-guide and check out this thread http://www.tomshardware.co.uk/forum/277215-11-intel-overclocking-club for ideas on what settings you can use and how to tweak for best performance,
I know in asus bios there is an option to change the voltage settings to manual input not offsets (you just type in the voltage value you want i.e 1.2v or 1.25v so on) I find this a less confusing method than using offset
