Now that Ivy has been out for some time what do you guys feel about running 1.4v with ivy bridge for everyday use which includes just gaming and web browsing. I usually use speed step which downclocks when under idle or light load. Would over 1.4 be safe for the same type of usage and what would be your limit?
I would say as long as your temps are fine, I dont see any issues. But 1.4 seem a little bit high, what OC are you running it at? Unless you run 5ghz OC 1.4v and watercooling, I would say 1.4cvore is too much either way.
Well I run mine at 1.4vcore as well, but vdrop under load is like below 1.4, I have full llc etc. But I have water cooling though, been running for 1.5-2 years like this I think. But if you go 75c playing bf4 that means you must go above 90C doing benchmarks.

Yeah I've stopped using stress testing programs like prime95 due to the crazy heat. I use it to find out my vcore under load and let it run for 10-20 mins. Then I just use it like I normally would and I've been fine. I check for whea errors etc. Yeah if I was to run prime it would probably be 90c. But during bf4 or gaming it hovers in the 50-60s with the occasional jump to 70c.
If you reach 75c while gaming, that seems a little hot.
If you don't use AC in the summer, that's likely to rise up quite high with the ambient temperatures getting warmer. Just keep monitoring it.
I sometimes see 75c when gaming on my 2600K @ 1.28, but it's usually quite a bit lower.
Since the workload shifts from core to core, temps even out to well below 65 in most cases.
That's true, his processor will throttle with a 212 evo. What I was trying to say is that he won't actually damage his processor untill he gets into much higher voltage ranges.
Really, since I have had mine at 1.4V almost 2 years, but I have WC. 1.4 = 1.38xx due to vdrop. Im not sure the cpus is degrading at 1.4vcore and why it even would degrade from the first place.
I call BS on that one. I think Wihglah spoke the truth and any interested parties will do well to take seriously into account what he said.
This is a typical and oft repeated phenomenon on OC.net. Every time an honest user such as Wihglah offers legit feedback, the thread below gets clogged by "angry protestor" type posters who deliberately make dishonest BS "bro" type statements in an effort to show the world just how "pro" they are. Unfortunately, this tends to misinform honest posters who read these boards looking for good information.
I think it is pretty safe to say that 1.4V VCORE 24/7 is degradation territory and could potentially even be dangerous as Wihglah noted.

The truth on this discussion is that every chip lasts high voltages differently and you can't really know before you try it out. It is highly possible that someone has had an IVB that lasted 1.4V for 2 years without degrading and someone had a chip die in a year. AFAIK someone on OCN ran his IVB @1.512V for months withouth degradation. http://www.overclock.net/t/1348694/i-7-3770-k-degradation-experiment
I would run any votlage as long as it's under 1.45v and 75c. Realistically the lower the better though, don't let stuff like Intel Burn Test stop you from going to a certain clock heat wise.
I.E my VRM's on my 290 get to 85c in MSI Kombustor (kind of bad for a watercooled card), but they've yet to pass 50c gaming. Do keep in mind that intel burn test. etc is a good point of reference for the MAX amount of heat the chip can output at those settings however.

The truth is that Martin Hal, the guy you refer to, only ran his chip "between 4.5 and 5.0 GHz" for 6 months before he sold it. Wihglah's above died after one year.
Well intels max recommendation is above 1.4v anyways. And technicaly I dont run 1.4 because according to hwmonitor its like 1.392 in normal use due to vdrop
. So, now im under and hence safe
. Or do you mean 1.4 in bios or after vdrop is taked into account? Please specify. I think people use that argument just because they fail to OC tpu that high or have a bad chip, hence saying 1.4 is too much. They also probably say 4.8ghz OC is too much and "unsafe".

It is important to note that these values lie outside the functional limits of these processors, that is, they may not be indicative of warranted operating voltages but are rather intended to serve as warning to those that would run their processors above rated specifications.
And how does that apply to me anyways, im under 1.4v in OS so im safe, right? Or can we assume the safe voltage is different depending on chip (most likely)?
It is impossible to say for sure b/c Intel did not publish Maximum Recommended Safe Operating Voltages for IB CPUs. They only published Absolute Maximum voltages.
The only thing one can do is note the relationship between Maximum Recommended Safe Operating Voltage and Absolute Maximum Voltage for previous families of CPUs and extrapolate same to IB CPU's (or Haswells).
In previous families, the difference between Absolute Maximum Voltage and Maximum Recommended Safe Operating Voltage was 0,085V. This would give 1.52-0.085=1.435V for IB CPUs but we have already seen that IB's are known to die after a year at 1.4V Vcore, so the actual -and unpublished- figure must have be lower than that.
Interesting discussion, I'm running my 3570k at 1.32 v under load on offset 24/7 at 4.4 Ghz. Just wondering what level of LLC people are using when their chips have died in a short space of time?
I'm using medium myself, which is the lowest setting available on my mobo, erring on the side of caution. Could it be the voltage spikes that vdroop is supposed to allow for that causes this early degradation?
Maybe he just kept changing his overclock, thus changing the amount of required voltage...
