Just booted my 2500k into windows @ 5.3GHZ @ 1.39v , loadline 10 and a gigabyte ud3p mother board.

oO


Would like to clarify if this:

^^ applies to i5 2500k cpus or not?


If it does apply to a 2500k chip should I stop anyway?


I'm not doing any stress tests, just booting into windows opening firefox so I can see the GHZ reading on Cpuid and realtemp to look at the, duh, temps.

44c running temps are what I'm seeing at the moment... [just spotted that wasn't with 100% fan speed tho, doh for next time] I have zero wish to stress test tho :P

As soon as you try to stress test, I recon it'll crash straight away.

Try running 1M super pi, that won't stress it too much, and post a screenshot so we know you're not just making it up ;)
 
Here you go!


Edit: Which brings me to another question: Why does cpuid always show vore of 1.044 at idle and 1.056 at load? Is there a program I can use to see the current, real vcore at all times?

Double edit: Haha, so that is the program used by everyone in the 5GHZ club, i see, thanks ;)

That is one monster overclock at normal voltage!
Mein gott in himmel you have a monster chip. :eek:


EDIT: hang on ein minuten bitte! That screenie shows 5.3Ghz @ 1.056v? Really? ^^

Okay, so how do I go about making sure everything is correct, then how do I proove the results? :)

fwiw the v core reading on Cpuid has always read 1.044 @ idle and 1.055 @ load. Even @ stock.


I'm setting the vcore in the BIOS and the temps and Gflops on intel burn are going up accordingly, as does the shown GHZ in Cpuid. (edit: Stopped using intel burn at 4.8 tho)

On the x50 multiplier run I used 1.39vcore because it would not go into windows without BSOD when set to 1.38vcore @ 50x, but it would at 1.38v and 49x. Windows booted into (at 1.39vcore) x50, x51, x52 and x53 but then would not load into x54. Everything definatly feels and looks like we are rising in .GHZ's! :S

That's when I came here to clarify the safe vcore of an i5 2500k, considering recent max voltage reccomened with the new 27000's :)


Wether you belive me or not, it's those questions I really need answering please :D, and if so, srsly, should I stop anyway? No way I'm pushing my luck past 1.39v if it's going to blowup in my face.


Double edit:

GHz means nowt without stability

Ofc :D, but, wouldn't that extra voltage headroom between 1.39v and ?1.45v? bring such things? presuming there was some real cpu cooling to keep temps down?

you can use higher than 1.39v for short periods, it wouldn't blow the CPU up just don't go silly volts like 1.6v :)

think even at around the 1.45v as long as you've got the cooling to handle the heat then that should still last you severals years, you'll be onto the next new thing by the time the CPU dies due to you putting 1.4v+ through it.

push the volts up and see if you can keep it stable/under 90oc, what cooling are you using?
 
Hi :) thanks for the reply.

I'm on air, using a Asus Axe Square which [[email protected]] keeps max temp of 73c max when running intel burn for 20 runs, in this case and fan set up. Next on the list is x2 awesome fans to replace the bitfenix ones next to the cpu cooler and put the bitenix ones in the last 2 fan spaces.


4.7/4.8 had the temps hot into high 80c's and [[email protected]] had me stopping intel burn when temps hit hit 90c.

From there I've not been stressing, I wish I had cottoned onto that light stress M1 super pi program sooner :)

push the volts up and see if you can keep it stable/under 90oc
You mean max temp at idle? with the split second M1 super pi test for simple stability checks? I'm not doing any serious lenghty stablity runs because I just know my cooling is not sufficiant. Great for 4.6 tho :P.

So I should stop, waaah :D

Untill I have better cooling, gah!

And that's +1 vote for 1.45v being safe for a 24/7 as long as cooling is sufficant, right? groovy.

Thank you.
