Haswell Overclocking Guide [With Statistics] - Page 327

post #3261 of 19637
You're missing the point. For me, lowering it helped. Haswell is a major silicon lottery. Everyone's experience will be different. Just because it worked for me doesn't mean it will work for others.

I was able to get to a stable 44 on 1.37 volts but I brought it down to 43 with 1.3 just for chip longevity and turned on adaptive mode with a 1.3 turbo.

I've heard that since the vrms are on the CPU buying a higher end board would do very little in terms of oc ability. I currently use the z87-k which is pretty much the cheapest asus mobo out there.

I'm pretty sure I lost the silicon lottery but would getting a higher end mobo give me more oc ability? I've heard rumors that some of the budget boards were somehow nerfed by intel to weaken their oc ability. This could be just be. What do u veterans think?

Me:

Did you increase input voltage vrin/vccin 1.9-2.0v try those values and report back try the following...

44x 1.35v

uncore 41x 1.21v

input voltage vrin/vccin 1.95v

good luck

JellzRoc:

Wow made a huge difference. Thanks!!!! 44 on 1.36 but seems much more stable
Because there is a unwritten rule for it

0.4 - 0.6v gap between Vccin and Vcore would be optimal.


So a cpu @ 1.25 -1.35v >> Vccin @ 1.75-1.85v,

default intel nominal is 1.80v
v


And using Vccin 2.0v or more for 24/7 is gonna kill the chip very soon.

44x 1.35v
uncore 41x 1.21v vring
input voltage vrin/vccin 1.95v

compared to

44x 1.25v
uncore 37x 1.12 vring
input voltage 1.83

Of course the upper Scenario would need more Vrin. Overall more Vcore and Vring voltage is set/necessary, more Input voltage is required.
In this example it is depending on the Vcore and Vring ratio/voltage set/needed for a certain Ghz.
If vrin is optimal in upper or lower case can only be verified by testing different Vrin values.
There are just so many scenarios that need different voltages.

WoW whos letting this guy post...pleas stop spreading these false rumrs...this is why folks are not getting the full capabilities of their chip..

Because there is a unwritten rule for it... So untrue please stop

Also again wow if you really trhink 2.0 will kill a chip than idk I give up good luck to you... rolleyes.gif

No, there is only 1 person propagating it. I too posted like 100 pages ago that VRIN is second most important voltage. It's just different for every chip and only way to find out is to run the most stressful tests, like intel linpack and p95 2.81.

yeah? then fry it idc.



ps., I know a reviewer @ techpowerup who made a Haswell review and tested various settings and he said over 2.0v is dangerous - he killed a couple of Haswells that way..

lol tech power up... dude we have ln2/diced/air way over that chips are running great....have a buddy running 5.2 2.2vrin going strong....these chips are not weak like yall think get good boards...wink.gifthumb.gif

heck ive had several in the 2.3v on air range nothing wrong learn to overclock....

please keep spreading this false info its amusing...

Yeah what ever, just dont cry if its gonna die soon lol xD
post #3269 of 19637
Why would I cry I have another 4770k sitting...you do know that intel has a tunning plan right.. And that this website is called overclock.net and under the title it says in the pursuit of performance....rolleyes.gif

since ur getting info from tech power up jeees. lol

Curious, those of you claiming 2v will kill the cpu, do you have any cases of this? Any specific examples? I am not trying to fuel flames but I am curious. Because the same was said about the 8350, yet I only saw 2 cases of people frying the cpu and it had nothing to do with the "unspoken voltage limit" but rather user error.
