currently, i have my e2180 at 3000mzh with 1.35vcore in bios. i want a higher speed, but don't want to raise the vcore too high. after about 50 times of reboot and testing, these are the lowest voltages i'm able to get for stability. the plot is relatively linear:

what is a safe voltage for 24/7? i will repeat this again with multipliers 9 and 8 later. will this maybe lower the required voltages for stability? i will post the batch # once i find the box for it
what is a safe voltage for 24/7? i
65nm lower then 1.55v but i recommand you keep it ~1.50v
45nm lower then 1.45v but i recommand you keep it ~1.40v

i know it doesn't show on the data, but at 1.5v in BIOS, i can get 3.3ghz stable. i didn't consider running it at this because my load temps go all the way up to 75-80C shown on realtemp. so at 1.4 - 1.5v, how long would this chip last?

Your temperature at 1.5V is too high. Keep it below 65. It's not just voltage that will kill your chip, temperature will do it as well. If you want to run 3.3, you need to get a better heatsink.
I am currently running 10x333 @ 1.52V Load in order to be Linpack stable (1.47V Load Prime95 Stable), but my everyday load temperatures are below 60C.

isn't ~1.5v still a little too high? i don't need this chip to last 10 years like it's suppose to on stock voltages. i need about 3 years on it, so would a 1.5v last that long for 24/?

i ran my e2180 at 3.6 with 1.55volts under a tuniq tower. temps at full load was 58c. i ran it like that for about 6 months with no ill effects that i could tell.

i guess your batch was a little better than mine. based in the linear relationship of vcore vs frequency, i'll only get 3.4ghz at 1.55volts. i think 6 months is too soon to tell for any premature degradation.

WhiteFireDragon ..are u using stock Intel cooler?

yup this is on stock cooler. are all stock intel coolers the same exact ones? when i can get a better cooler, hopefully my clocks can be a little higher...
