Well just so you know according to AMD the max voltage for the FX chips is 1.4125v.

1.5v + for the previous gen 45nm was perfectly fine, but not for these. 45nm =/= 32nm.

Run Prime95 for 24 hours on large FFT's with 1.55v @ 5.0Gghz and report back. thumb.gif

lol have you used bulldozer before? how do you think people clock them so high? 1.4v stock, how the heck are people supposed to overclock it then..

It may be 1.4v stock, but I bet you could easily undervolt it to 1.3v and maybe lower and still be stable at stock speeds.

Think about it. 1.5v was, and is still generally the max voltage used for Phenom II 24/7, and 1.55v if cooling is sufficient/user didn't care about lifespan. That was 45nm tech.

Now why in the world would 1.55v be safe 24/7 on 32nm tech?

i also dont care about lifespan. im getting rid of my 990x platform and going sandy bridge/ivy bridge. i think 1.55v for benchmarking and stuff is fine as long as its not 24\7

Not everyone can afford to replace a chip, even if it is on the cheaper side. One of the things the OP wanted to know was what voltage he should use, not what voltage he should use if he wanted to "overclock the living spit out of it".

So again, 1.45v is my suggestion for 24/7 use. 1.5v borderline if you really wanna push it OP. And if you don't care about the chip and wanna "overclock the living spit out of it" then go ahead and use that 1.55v or even higher! thumb.gif

I know all about overclocking $100 chips... 1.552v on a i3 540 @ 4.60ghz stable thumb.gif

I hit 4.96ghz suicide runs thumb.gif


375


To the OP,

My i3 540 died after 6 months at 1.55v 24/7 use with folding and gaming. I would recommend 1.45v as the max for 24/7 use.

well i know what your saying. but i didnt run 1.55v for more then 3 months. im now back at 1.45v and 4.6ghz. for 24/7.

and as for undervolting... i couldnt go below 1.375v or i wouldnt boot, and that was at stock clocks.
