SB safe volts confirmation

[Henrik]

I'm sorry for you m8..

I have also done some reading on "safe" volts for the SB. There are allot of forum threads out there where people are stating that 1.52V is safe for SB. Just because they read a Max Vcore in the Intel document. Now where on page 80 of the following documenthttp://www.intel.com/content/www/us/en/processors/core/2nd-gen-core-desktop-vol-1-datasheet.html) stats that it is SAFE. It only stats that 1.52v is the max voltage.. In other words i believe it is the max voltage you CAN run before damage will most likely accrue. That dose not mean electromigration is not present up to 1.52V... We all know that you will degrade a CPU faster with higher volts or/and higher temperature. Witch means electromigration is dependent on temperature and voltage. Then why dose not Intel specify a max SAFE voltage?... I think its because every CPU is different and they will not all degrade at the same speed at higher Vcore. Some degrade very fast other not as bad.

If you would have asked me I would think that 1.4V will not degrade your chip within 1,5 year period. You must have had very bad luck m8.

1.39v for about 10 days

unlucky for sure (because temps were not high) but I guess 5ghz was too much for the chip to handle F@H for long periods of time...... Oh well now I know for next time right

what was the temps at you keep saying not to high but it may assist others. So spill it mate what were the temps at lol

Lol + 1.

I'm more curious about his PLL voltage; I've heard exceeding 1.85v will degrade a chip in about a week. Currently I'm shitting my pants because I'm at work, and my pc is priming at 1.4v at home, and if 1.4v causes 10 day degradation, then FML. But if his problem was excessive PLL voltage, then I'm okay.

haha sorry, i haven't been on here in a bit

well my temps where in the range 60-65C (depending on room temps), which is pretty low i would say

i didn't touch PLL voltage at all, the only voltage i changed was the core voltage and on the memory i think i put 1 step over 1.5v just to make sure it was stable since i decreased the 2N or whatever to 1.

as for your chip, it just depends on the silicon lottery i guess

That's scary stuff =/

I dropped to 4.9GHz because of this thread, because I know I can run that under 1.37v, and I see no difference between that and 5.0.

It's not volts that kills CPU, or is safe/not safe, it's heat.

If you want to pump 1.7v through your CPU, good luck in keeping it cool.

The only official line from Intel was 1.52v, and many benchmarkers and myself exceed that perfectly fine.

Voltage does degrade the CPU even if you can keep it cool. If I find the source I'll edit it into this post.

OP was saying that his didn't go over 65c in those 10 days of folding, so, something killed the chip. I'm guessing he just had awful luck, but who knows? What really scares me though is that mine is a high clock/low voltage monster like his was (4.9GHz stable at 1.365v is what I'm currently doing), so what if mine is doomed to the same fate? I'm paranoid though, so whatever.

So I guess my question is, are there people that have been running 5.0-ish in 24/7 builds, and if so, how long have they been going for?

this is COMPLETE poop, heat does degrade your chip, but volts DEFINITY do too. you should read more on the topic.

and i had a 60mm 360mm rad only for the cpu, and as i said it NEVER got too hot, but it definitly damaged the chip.

Also cbgoding, you probably wont have the same problem as me because i left my cpu at 100% f@h, under normal usage the degredation probably wouldn't have occured so soon
