Question Does anyone have experience with undervolting AMD FX chips? (FX-8320)

Doing this for temperature reasons... right now I'm running at 1.175v for a few days now with no problems. Was curious if anyone knew roughly on average what the minimum would be?

All chips are different and depends on the chip sample. To obtain the lowest Core voltage you keep dropping core voltage in .01V steps till the system don't boot then raise in .02V steps till it does under load at a given frequency.

I doubt 1.75V will hold stability wise when under load either that or your underclocked considerably.

yeah Ican be playing a game and doing a/v editing fine, and I ran prime95 just now for about an hour, cpu diode stayed around 57c, mhz stayed at 3512, and the cpu voltage stayed around 1.175-1.18, never went over 1.2v

Yes well those figures are good for stock frequency and the cooling system you have.
Was there anything else you wanted to know regarding your CPU ?

If you have good cooling you can oc it till 80c but why whould you want to keep temps super low anyways? 50 is low and if i did have that much headroom i would overclock the crap out of my proccesor till it hits 75-80c (i use lga 775 wolfdale e5300)

Well I've always tried keeping it under 74c, cause when I used to mess with AMD Overdrive, i always assumed the thermal margin was the max operating temp, and 0c thermal margin if i remember right was 74c.
