I've just got a couple of I'm sure already answered questions.. if they have already been discussed I'd be perfectly happy with a link to them.
Anyway, I think it's pretty common knowledge that you add voltage to an OC to make it more stable, but adding voltage has "diminishing returns" in that you will need to add more and more for the same effect. I've also heard that you can add too much voltage which will fry the chip (I'm assuming this is basically just electromigration?). Assuming the last statement is correct.. I was reading that electromigration is basically caused by heat (not voltage.. although voltage causes heat), so my question is if it is "safe" to keep adding voltage as long as I keep an eye on the temps.. or are there more variables I am not accounting for? On a related note, I've seen people talk about OC voltages and then regular voltages (like OC comp to see how far it goes.. then go back a few notches so the voltage is a bit lower).. which I assume is again to lower the heat -> lowers electromigration -> extends life of chips, but again I'm wondering if my focus should be more on the heat the voltage causes rather than the voltage itself.
The main reason I'm asking is that I'm trying to OC my Phenom II x4 955 processor (stock 3.2 ghz).. have gotten it up to 3.8 ghz pretty easily, but I'm nervous adding more voltage before I really understand what it does. I bought an XSPC Rasa water cooling kit a while back and the core temps sit ~46C under load @3.8ghz (my original goal being to OC it to 4ghz).. and it seems like I have a bit of wiggle-room in terms of the temps to try to hit that 4ghz goal.. I was just hoping somebody could either give me the go-ahead to keep going or stop me before I "fry" my chip.
Thanks,
