2500k won't overclock over 4.5ghz

[Flavlus]

I'm running this on a custom loop A240 ekwb. 

 

I have to run it at 1.41 Volts at 45x 100mhz.   Temps are around 60 C when stress testing for an hour or so. 

 

I have also disabled that stuff to do with underclocking it safety stuff and all that turbo stuff 

 

I have not touched anything else 

 

Stress testing with aida64 and prime95 and some cinebench

 

Mobo is a z68 gigabyte.. Ud3.. Can't remember actual model name. 

 

ANY HELP WOULD BE AWESOME

Is it not stable above 4.5? If thats the highest you can go, thats the highest you can go, just luck with the silicon lottery.

you can shove 1.45v through it no problem, have you tried messing with the system agent voltage? formerly qpi/vtt. your temps are fine... keep going with the voltage

I'm not sure about this voltage. I had a 4790k and i'm pretty sure 1.4v was considered high even for a custom loop, I don't think the OP should be pushing more than 1.35v imo.

Have you tried your LLC voltages?

4,5ghz is in the good middle range.

yea I'd increase the Digital and Analog I/O voltages and the System Agent, i am running +0,125V offset on all of these

4770k is bottlenecked by the crappy TIM a lot. If you can delid then 1,4V are easily doable while staying below 75°C

I can run my 4770k (delided) on 1.4V air cooled (90°C).

i don't think the question is how doable it is, but when do you start shortening the life of the CPU

To be fair it really depends on a lot of things. 1.4V is fine for daily use with all the C-States and EIST enabled for the voltage/frequency stepping.

If you did a heavy workloads most of the time on 1.4V when CPU is pinned hours at 100%... that would be an issue.

this has always been dragged on, a beaten dead horse discussion. I would be weary of the new finfet chips, but anything 45nm or 32nm from intel can take a beating. plenty of guys from Q6600 days started calling bluffs and running 1.6-1.7v daily, and as far as i know those chips never had problems before they were retired to the trash bin.

 

personally, I had a i7 930 running at 1.45v 4.1ghz HT on for 6 years, it's in my closet good as new. I threw in a X5650 in january, been running it at 4.5ghz even higher voltage since then without problem. They're about $38-48 a piece now so it's great to experiment with

yeah, i guess i'm just a pussy. Keeping my v @ 1.40 for my 2600k, hoping it will survive until Ryzen 2 comes out.

Im happy with 1.41V actually ... i just want to clock higher.   Temps are well under 70. Core 1is around 55 , 2  = 60 , 3 = 64, 4= 60 >>>>>

Not sure why they very so much.

You want to go from a 4 core 8 thread to a 2 core .. maybe 4 thread cpu ?

I'd venture to say that your overclocked 2600K will kick the snot out of Ryzen 3. Remember, they're only 4c/4t and won't clock as high. You'll probably want something like an R5-1600 instead if you want a big upgrade.

Thats what i said ... and he wants ryzen 2 not 3 LOL . Whenever taht will come out. Im thinking going R5 1600 from my 2500k ... but its a lot of money to do this big of an upgrade. Mainly cause ill need to get new ram ...Damn DDR4
