i5-2500K is 5.0ghz reasonable to expect?

[hifidelitygamin]

Depending where I look i'm led to believe that 5.0ghz is almost a sure thing, and other places suggest that is a stretch or difficult to achieve... i'm referring to 24/7 running without 'dangerous' increases in voltages, and assuming solid air cooling.

Unfortunately, it's not a sure thing.

With high end air or water, you'll be more likely voltage than temperature limited.

Some chips just won't make it below 1.52/1.55v, even staying within a safe temp range. Luck of the draw...

4.8 is more like a 90% thing.

I'd say 4.5GHz is guaranteed, the higher you go past that, the less likely it is.

What happened was that, when the 2500Ks first came out, 5GHz was pretty much guaranteed. The chip quality got worse as time went on.

Think your right Knufire...and 5ghz being a sure thing ? nah not really...i think i got the ****ty end of the stick aka a 2500k that doesnt seem to go past 4.9, tbh ive not really been tweaking all that much...but the voltage increase needed just to get it to post at 5ghz (post but crash while booting at 1.53v so far)doesnt exacly look good.
I tend to agree on 4.5ghz being the sure thing...over that is hit or miss(ive seen a few having trouble even getting over 4.5), i run mine at 4.3 normally as the voltage increase to get that is so little it makes good sense and i barely have any temp increase at that speed either, performance gain is noticable though vs stock speed.

 

[Knufire]

No, no, by long time ago I mean the first 3 weeks when the 2500K came out, everybody could hit 5GHz. Dropped really fast after that.

5Ghz with reasonable voltages on the 2500k was always a concern AFAIK. No guarantees after 4.5Ghz+ is my take.

I get 5.2 at 1.53Vcore... I can get 4.75 at 1.38Vcore.
Provided you have a good cooling system and a good chip, you should be able to have a daily driver at ~5GHz.

1.55v 24/7... Let us know when that chip dies/degrades.

 

[pan1cattack]

It's been 7 months so far and still the same 3DM scores...
Temps below 30C at idle.

 

[EarthDog]

Scores do not matter (it runs or it doesnt, you wont get 'less' on a degraded chip at the same clocks), neither do idle temps (its load temps that matter most, but on your case voltage assuming temps are under control. You are a brave soul. I experienced degradation at 1.55v quickly with a 2600k. Every piece of silicon is different, but anyone with a clue recommends 1.40-1.45 as a 24/7 limit. 1.5 some will do, 1.55 is not a good thing to do. It may last a few years, who knows though.

Guess it fits nicely with knufire saying chip quality has gone down...i bought mine like 2-3 weeks ago....anyways...1.5v+ not something i wanna do 24/7 and tbh the performance gain aint all that big like it is from 3.3 to 4.5, not talking benching but every day use/gaming and whatever, i do run mine at 4.9 tho when encoding, not that it makes that much diff tho...more coz i can lol
