2500k overclock problem..[SOLVED]

[danBrown]

I'm having a problem with overclocking my 2500k.. if i overclock it to 3.7 or higher it goes to 97 degrees Celsius.

I have a CM V8 cooler and i had taken out the stock fan and placed a silverstone AP121 in there (it was recommended to me)

I use Noctua NT-H1 Thermal Compound

 

now I've seen people get 4.5ghz on similar coolers with 80 degrees max. 

 

i live in Australia so its not the coolest climate but generally in my house its around 24 d Celsius. 

 

So im wondering what I might be doing wrong with trying to overclock this to 4+ghz. 

 

my setup includes:

gigabyte z68-ud3r-b3

2500k

CM V8 cooler (silverstone AP121 fan)

silverstone 750w PSU

250gb SSD

Case: Antec 900 V2

 

If i need to include anything else here please let me know. 

If any help could be provided it would be much appreciated. 

Thankyou for reading this,

DB

How are you overclocking? What settings?

[IVIeLt]

What's your voltages and what speeds are you actually running the fan at?

 

Also might be worth a try to take off the cooler, re apply your thermal paste and put her back on.

[mvitkun]

as said above

-try remounting the heatsink

-re-apply the thermal paste

-make sure NOT to use the OC software,OC from the bios 

 -use fixed or offset voltages,NEVER use auto voltages when OC'ing

-OC the turbo clocks rather than the regular clocks,allows downclocking when lower cpu usage to save power and generate less heat

 

what voltage do you have it set to?

whats the max vcore during Prime95?

check with HWinfo.

 

what program are you using to monitor cpu temps?

again try using HWinfo,or you can try coretemp,or realtemp

those are ones that are accepted as the more accurate programs

[Morfy]

It sounds like you have some huge voltages

[garbeth]

change voltage probably is to high, i have a 2500k and i hit 4,6Ghz, my voltage is 1,480, so have a look.

 

let us know how it went 

[Chakshu]

your voltage is too high aimfor around 1.35 for 4 GHz

[danBrown]

i reapplied the thermal compound also wiping away the old stuff with the isopropyl alchol . the temps did drop a little bit. 

 

i should have mentioned that i am new to the overclocking game . I was following a guide online. TBH i really got no idea what to do for overclocking. I found online that the noob friendly way of doing it was to just change the multiplier  so that was what i was doing. everything was on default apart from the multiplier. 

 

I'm honestly not too sure what needs to be changed. But I would like to learn about overclocking otherwise i guess it was a waste spending the extra $30 or so on the 'K' processor. 

If anybody knows what to change in the gigabyte bios to get some overclocking going it would be much appreciated. :D

thankyou for your responses so far. I guess I should have been more specific in my original post.

Oh god! You kept the voltage on auto. You will have to manually select a voltage otherwise your temps will go waaaay too high. Just google for an overclocking guide. Any good guide will tell you how to achive the lowest possible voltage with your desired speed

[garbeth]

I made a bit o research for you and i found some info that maybe helpful this should be your settings in this particular mobo for a 4.5 Ghz hit.

Here's for a quick and dirty overclock:

 

Set cpu multiplier to 45.

 

Set cpu core voltage to 1.4

[danBrown]

@Garbeth, I went online and found a similar guide to that one and tried both yours and theirs and my idle temps were about 70 degrees and under load i had to stop the test cause it was rising so fast it got up to about 97 degrees when i turned off the test. 

 

I also found another guide for getting it to just 4.0ghz. I heard that not all cpu's can go overclocked to 4.5 so I'd figure id try it. Ihave some pics here for the temps and voltages that were obtained. The settings i had in the bios include: 

 

PWM Frequency Control.[Auto]
CPU Over Current Protection. [Auto]
Internal CPU PLL Overvoltage.[Disabled]
Real Time Ratio Changes In OS [Disabled]
Intel® Turbo Boost Tech  [Disabled]
Turbo Power Limit (Watts). [Auto]
Turbo Current Limit (Amps). [Auto]
CPU Cores Enabled  [All]
CPU Multi Threading. [Enabled]
CPU Enhanced Halt (C1E) [Disabled]
C3/C6 State Support  [Disabled]
CPU Thermal Monitor  [Enable]
CPU EIST Function  [Disabled]
Bi-Directional PROCHOT  [Disabled]

Multi-Steps Load-Line  [Level 4]
CPU Vcore [ 1.270v ]

(sorry don't have the site handy)

 

I ran it on prime 95 for approximately 4 hours to get these results.

Is there anything you see that i should be changing?

Thankyou for reading. DB

 

EDIT: could this be a problem with the motherboard? its a fairly cheap one... 

[fishymamba]

Sounds to me like you are putting the heatsink on incorrectly, 70C at idle is crazy no matter what voltage you are running. 

Are you sure you are putting the heatsink on correctly? How much thermal paste are you using? 

I am able to hit 4.8 Ghz with my 2700K with the same temps you are getting and with a cheaper cooler. 
 

And no, a motherboarod would not cause high CPU temps.  

 

Edit: Is the cpu fan working correctly? 

[danBrown]

i followed the guide linus put up on youtube for installing a heatsink. (with thermal paste as well). ill take it off again tonight and try installing it again.. if that fails i guess ill go buy a new heatsink. which one do you use out of curiosity?

[fishymamba]

I use a $30 Hyper 212 EVO.

[danBrown]

I took off the heatsink and cleaned the thermal paste. reapplied and made sure the heatsink was on properly. and I'm still getting the same temps. Tomorrow i might go out and buy the hyper 212 since its cheap and see if that works better for me. if it doesn't ill just get a refund. and if i can't get anything to work for it i'll just give up on overclocking till i find someone to do it for me . 

Thankyou guys so much for replying. believe it or not it has been a big help. cheers.

Whats your temps at stock speed?

[danBrown]

at 4ghz stock was about 49-52degrees Celsius. from what ive read here and online elsewhere that seems to be very high. room temp atm is about 20 degrees celsius (very cold for qld aus)

[R4STABAN]

your voltage is too high aimfor around 1.45 for 4 GHz

 

That's crazy volts for 4ghz!

[DoctorNick]

That's crazy volts for 4ghz!

It is. My 2500k is at 1.352v at full load at 4.7Ghz.

[R4STABAN]

It is. My 2500k is at 1.352v at full load at 4.7Ghz.

 

2700k 1.38 v for 4.8 ghz here, I would never exceed 1.38 v for 24/7 use.

If you reset all the bios settings on default. what temperatures do you get?

 

I mean if you do not overclock at all.

[danBrown]

I got bored so i woke up... updated my bios to the lastest version as i thought that might have something to do with it. i set the 'Boost' to 4ghz and the Vcore to 'Normal' i was bored and frustrated so i decided to try that.

these are the results that i got.. they are all different for some reason .. a little annoying as im not too sure which one to read off properly.

EDIT: currently at these settings idling at 23-26 degrees in touch bios... 33-37 in realTeamp.... also the turbo just randomly kicks in a sends the temps up about 10 degrees but only for a few seconds. (i guess thats normal)

 

 

If you reset all the bios settings on default. what temperatures do you get?

 

I mean if you do not overclock at all.

It idles around 35 degrees in RealTemp and about 26 in gigabyte touch bios... so not too sure which to belive there..

 

also its freezing here right not.. its like 17 degrees celsius ...

[aissixtir]

<p>I know this might be a poor suggestion as my knowledge is non-existent but man are you sure the cooler is in contact with the cpu surface ?<br />

<br />

also when you removed the heatsink to re-apply the thermal paste, did you have to clean both the cpu and the cpucooler or was the cooler "clean" ?</p>

[danBrown]

na fair enough question.. i did have to clean both the cpu and cooler.
