What other settings did you play with? What are you crashing with?

If you don't state those, honestly you're just making it more difficult to help others in the thread and i don't know what you want by complaining other than.. complaining

Either from the videos i see at youtube, from Asus showing rog boards guide overclock, my board bios settings work different from them.

In rog asus forum some guy say that adaptive mode in asus you put the value of you desired max vcore at "turbo max frequency" which is a setting inside adaptive mode in Asus. I put like 1.15v and that should be the vcore your cpu use when under full load at applications, but it dont work like that on my board, my adaptive mode have some "auto voltage" which gonna be 1.20v ever, same when i put 1.15v under "max turbo frequency" inside adaptive setting. Under applications load(not synthetics ones, only normal apps, games, sony vegas and such things) the vcore will run at 1.20v instead of my 1.15v choice.

I see that inside my "Adaptive mode" have another option which is called offset, to me set + or - voltage, so i need to know that my board gonna use 1.20v and then go there and put -0,050v inside adaptive mode offset, which to me look the offset modeworking inside adaptive mode.

At manual mode in my asus board the vcore will never drop from max value, like 1.20v or whatever is the vcore, but the frequency clock will drop to 800mhz running with vcore of 1.20v.

So because this im a bit frustrated with this settings overclocks, maybe its my bad because i choose a ASUS board and anothers brands have not such problems.

You might be able to get vcore drop without using adaptive or offset, i would definitely try for that first and talk to darkwizzie etc. If you can't, offset might be better.

I'm not afraid of going over 1.3v, but 1.48vid (1.5vcore dmm at load) is puuuushing it just a little

According to what? I'd be really interested in checking out an official data sheet that details the maximum safe voltages for Haswell....A good chunk of people seem to believe that 1.4v is dangerous territory - though there hasn't been any evidence to back it up....Short of the person who killed their CPU by running 1.5v+ vcore, along with 2.2v vrin....

Good fellow posted this for me in the thread, I am doing the same biggrin.gif

I can't cite any report of degradation that has good and thorough tests before and after. There's been a few what seems like instant deaths, one from running prime on adaptive voltage around 1.3-something volts, one from ~1.52vcore priming (but maybe not the chip) so it's very hard to say anything

All i can ask is that you do detailed degradation-checks and log stuff so that we know if you run into bad stuff 2 months or 2 years from now wheee.gif

Well, I see a common factor in both of those scenarios that you mentioned: Prime95. Personally, I see absolutely no point in running that. Also, my CPU isn't seeing a constant 1.48v due to the C States that are active...wink.gif

Nice post, I've seen that...The downside is this: it is by no means an official data sheet - it serves as more of a guideline, one in which I seem to be following pretty well. That chart suggests that 1.45v is the max for air cooling, and I'm running a CLC...thumb.gif

You don't have to run a full range of prime to test the chip either.
It's possible to run a quick 90% ram with 1344-1344 3-5+min tests or 1792-1792.

I ran x264 for more than 10minutes with no bsod, chances are it would of bsod in a few hours.
I ran prime95 with 1344-1344 for less than 1 minute and bsod

Prime is a great tool for hardcore stress testing or just eliminating quick bsods.

1.5v

your cpu isn't seeing a constant 1.5v tongue.gif

IVR vcore target is 20mv higher than set in bios

Good luck though! Let me know how warm it is lol

Which version?

Not very warm at all....I'm delidded, with proper TIM, and an H100i in push/pull.... biggrin.gifthumb.gif



The highest it got while running LinX was 72*C....
