CPU IO SA voltage

[DEST98]

quick question

overclocking right now saw a few guides online that tweaks these 2 variables(CPU IO/SA)

i've already got a stable 4.5 with 1.28v on my 4770k

also tweak up my cpu ring clock and voltage already

 

so here's the real question

should i bother tweaking those 2 variables(cpu io/sa)

and if i should how and why

[Derrk]

if your system is stable, no need to give it more voltage

[DEST98]

havent ran a long hour stress test yet (5 hours max for now)

whole system is running quiet hot in load maxing just below 90

and ive heard that adding voltage to those two (maybe) could bring the temp down

cpu io/sa values can increase stability at higher overclocks, if you have no stability issues stock values are fine

ok thanks

last question

if i just maybe wanted to tweak those two how should i

eg:cpu v core just need to increase it to stabalize but io/sa needs to tweak to a certain level as i have heard

if you guys have tried it can i have a little info on how do you tweak it
