Agreed. The game has been, for the most part, fixed. I still wouldn't use it to test stability 100%, but now it is very unlikely that the game will cause you to BSOD.

-Everybody is already under the impression that 1.5v and higher is asking for a degradation trip. I sorta feel that if the number were 1.55 or 1.6 or 1.51, it won't really change the perception of the people that overclock. Quite a few people would argue (regardless of whether they are right or wrong) that 1.5v is already asking for CPU death. I'm not sure how minimal is minimal degradation, it seems vague to me. 

 

-Everything dies eventually. Overclocking increases the rate, but by how much? Without any statistic, the idea is meaningless.

 

-Yes, the large majority of us will agree that 1.5v and higher is not that safe. But imagine if you are thinking of hitting 1.42v like me... Is 1.42v far enough from 1.51 so that it's relatively safe? Imagine if we could tell statistically, the probability of CPU degradation at a given voltage X number of years down the road. That would be amazing and we could be so much more informed about our risks. How far from 1.5v is safe enough? We're going off of our guesses. 

 

-Yes, Intel's number is a figure just like my figure and other people's figure, a range or estimated voltage in which your CPU isn't 'safe enough'. I can't exactly say my figure is much better than Intel's. We're just pulling out numbers. Somewhat educated guesses. But imagine if we could manage to get data from thousands of dead or degraded chips. That would let us put out data and voltage guidelines that are so much more accurate!

Just....wow.

:h34r-smi

 

Computer just glitched out on me, had to restart.
Anyways, the point is: Until we get statistics and testing or a sample of failed CPUs and their settings, anybody's estimations are simply estimations and nobody's opinion of safe voltage can really be taken to be god's given truth. Sure, our estimations beats out random guessing for sure. But it would be way better, I would feel way better, if the guidelines were backed up by empirical evidence.

Are you sure your ram timings are correct? BF4 was driving me nuts until I realized I didn't fix my ram timings when I overclocked it.

bf4 bluescreened me harder than other stuff before, chance of error goes up and up with time; can just add another 0.01vcore and expect it never to happen again if it took that long IMO

I was getting ready to say biggrin.gif Technically you have not been stable for one month now such big post:D (Click to show)

i know it seems people don't like many of the synthetics of this thread, but that really is the point.
If you passed 100 x264 runs, then 1 month later you crash in battlefield 4, might as well had tested with prime95 for 12hrs minimum to 24hrs + to guarantee no chance of BSOD with any situation for the CPU

Sure it will stress the temps to unrealistic amounts and workload, but that is the point of becoming stable biggrin.gif

or that biggrin.gif if he OC'd memory good thing to do is run memtest on max memory to see if it passes 100% with 0 errors i assume ?

Can't disagree with that. While there is the element of common sense, need real data to back up any hard values. Data, data, stata biggrin.gif

Wizzie, feel free to utilise my stock? gif if you please wink.gif

Isn't intel spec stating the max Vcore for haswell = 1.5v? 99.9% sure I've read that somewhere (probably on OCN)

Probably in part due to low input voltage. 1.42v I needed 2.15v. 1.35v I needed 2v. You can go to 1.5v VID and you still won't be stable if you don't move that input voltage, guarentee it.

 

In other words, just raising that VID to a very high value won't cause stability if your input voltage is too low compared to your VID. As VID increase, input voltage should also increase, and this is much more important at higher VID.\

 

I'm trying to chart you but you don't really have any stress test filled out...
