5.0Ghz...so close. Help!

post #1 of 24
Thread Starter 
Hey guys. I currently have my 2500k 24/7 stable on 4.8Ghz@1.44v. Temps under blend reach 76c, and really I'm ok if it reaches up to 84c, as it's a stress test. But...I want more!

The problem is, I have to bump the voltage to 1.52 to get 4.9Ghz stable, and then at 5Ghz the blend fails after a few minutes. Temps were at 83.

I think I've tweaked all I can, but I wanted to make sure I didn't miss anything. Mobo settings were as follows:

CPU current 140%
VCCIO@1.2
PLL Voltage@1.8
Load line calibration=Ultra High
VRM@350
Phase and Duty Control@Extreme
CPU Spread Spectrum=Disabled

Anything else I can do?

i've noticed that the 2500k's usually hit a wall at 4.8
i don't think it's worth throwing so much more voltage into it for so little performance increase. I mean dont get me wrong, i would prolly be trying to hit 5gHz as well but it's not worth losing the stability for such a small increase.

84c..... o_O Sort those temps out and you could probably go further. 84c is ridiculous.

84c is absurd, i dont break 70c at 4.7. Not to hate, but if u need 1.44v to get to a stable 4.8, ur chip prolly isnt the best, and going for 5.0 would just be reckless.

o wow i guess i didn't read the whole thing. 84c is high (although it's not as high as these ppls make it out to be, it's not a good idea to hold it at these temps). You need at least water cooling if your going to go any higher. I meen, im sure there are regular fan sinks up to the job but by the looks of it your just trying to get ur clock as high as possible.

you can build a custom system or i've heard the H70s work good enough for the 2500kif you're on a budget; although i swear on the nerdy computer gods that one of those prebuilt water systems will never come within 20 ft of my computer.

I know, it's hard to get better temps, and I'm using the best air cooling available. My chip does seem pretty poor, but then again, shows how awesome the 2500k is. Even a *bad* chip is fast as hell.

So unless someone else has an idea, I'll concede that I've reached my chips limit. I'll be safe at 4.8Ghz, may even be able to nudge the voltage down to 1.42@72c. Thanks guys... *sigh*

I'm sorry, but the only water cooling worth it is the custom loops, and well, spending hundreds of dollars just for a couple more hundred mhz is dumb IMO. I prefer air cooling.
Edit: Think I should try reseating the CPU?

It's the HT that contributes to the heat, it would probably clock the same as a 2500k if you took HT off, but then again, you must have bought the 2600k for the HT, so 4.8 plus HT is pretty good.

EDIT: It does seem that you have pretty much tried everything, I think if you can keep it below 85c, that's pretty good. in Real time nothing will really stress it as much so those temps will more than likely be lower, as long as you can get it stable I say why not.

Wait what? I have a 2500k.

84 is NOT ridiculous at all. I have not heard a single i5 died on 84c. Not even 1. So how's that ridiculous?
Some core with max spike temp will reach 84 in Air cooling with 4.8GHz+ with IBT/LinX (AVX).
I see no problem. Just remember the CPU will throttle down at 95c and 98c is the max max temp.
Some people are way too conservative about the SB temp...
I personally don't mind going to 80c+. been doing stress testing almost everyday for a month or so. I see no degradation whatsoever. Keeping it very stable. (seems like hi voltage will do degrade the chip in time whether you have your temp low or not.)
Reaching 84 in IBT/LinX (AVX) means real life max CPU temp would be about 75c~80c, idles at 35~40. (including Prime95)
That seems all fine to me.
I personally want my system to be as MANLY as possible.
I make it work hard and won't let it stop.
When it dies then it dies. So be it.

As said, you probably have a bad OCer.
Reseating the CPU probably won't do much. Neither will changing your air cooling sense you have a pretty nice cooler.
At least you know your limit now.

Temps are actually fine, sense Intel can withstand higher temps..unlike my Phenom, which should stay under 62C. Doesnt have to, but its recommended.
