Overclocking my Intel core i5 2500k

[Mrboxfacetramp]

Hello i have already had a post about overclocking my intel core i5 2500k but i have actually managed to achieve a 4.5ghz but i dont like the readings i am getting off of it.



I am getting a reading off of HWMonitor saying that after only a 30min run on prime im getting 78c which in my opinion is too high and should be maximum of around 73c. Also it states that my voltages hit 1.45 which is also way too high. Overclocking on my board is also a pain and i have to work in increments and i can't acutally set a voltage which in my opinion makes it redundant because it never follows the increment i put.

So any help that i can get will be appreciated.

p.s; for cooling i am using the Arctic cooling freezer 7 pro rev 2

Hi buddy, im new to the forums so bare with me lol.

I have the same chip and im only running on a stock intel fan! (Waiting on a xspc watercooling kit to arrive) My max temps go to around 73c running prime around 30 mins so not sure why your is so high with a performance cooler! Also the vcore voltage is way to high in my opinion.(Btw im overclocked to about 4.4ghz!)

What board are you running?

friend, first of all tom has made a video about OCing the 2500k and 2600k and he took the 2500k with noctua nhd-14 to 5Ghz

on 1.42V maybe a bit more yours is already at 1.45 and with a lower OC.

now im not saying your doing anything wrong, and 76c is still with in reason. so i have some follow up quations:

1.have you tried running that clock on a bit lower voltage(1.36-8)?

2.what is the ambiant temp? room and case.

3.are you OCing manually through the bios? and got the latest bios?

4.what is your mobo model?

Thanks for the support,

My Motherboard is an ASUS P8Z68-V LX and is really getting on my nerves for overclocking. In the bios as i already said there is no possible deffinent o'c and i have to work in increments but it doesn't tell me what voltages i am changing to so it makes it redundant. I decided to try out there Turbo-V software and was able to get a 4.5ghz with a 1.32v that sometimes dipped to 1.3.

I ran intel burn test and it pushed 75c out of the chip (Reading Package). I am going to try and put the same settings from the Turbo-V Into the bios and see the effects.

Just achieved a 4.5ghz at 1.3v which in my opinion is much better and hit a top temp with intel burn test of 71c

Hi there buddy, it may seem a bit noob to some of the more experienced overclockers, but i too used the Turbo-V Evo software to achieve my first overclock of 4.3GHZ then adjusted slightly from there onwards. In my opinion this is a great way to get a nice stable overclock without messing around and wasting time.

Just my take on it though, again im not a huge overclocker but this certainly worked for me mate

All the best!

With the Asus P8Z68-V Pro BIOS, you can change the voltage method from Offset to Manual. It ought to be quite similar to your board. In this BIOS there is a button right above where you enter the voltage and by default it is set to Offset. This sounds like what you are describing for "work in increments but it doesn't tell me what voltages i am changing". Are you sure you can't toggle the button to Manual? Then you can enter fixed voltages. What you give up then is the power saving features as the voltage stays fixed no matter what your CPU usage.

Yeah i have seen videos of this setting but it is non-existent on my motherboard ;]

Sounds very similar to myself ;p

After having it for about a year I decided to overclock my 2500k. Unfortunately im running into a problem. I went into bios an set my multiplier to 45 (4.5GHz), I ran the Intel burn test, and I monitered everything with CPU Temp & CPUZ. After a couple of test it kept saying, it didnt found any errors which would mean its a stable overclock. So i was pretty happy. But lately i've been getting blue screen errors (STOP 0x00000124), turns out overclocking could be the reason for this. But the test said multiple times it was stable. The only weird thing I noticed was that my MHz sometimes switched to 1600Mhz for a moment and then went back to 4500Mhz, but I never knew why it does that. I only changed my multiplier to 45, maybe there's something else I need to do? Anyone have an idea?

The change in clockspeed will be Intel speed step, it downclocks your CPU when it's not on load. it will make your clockspeed go up and down for a brief moment when it's not on load whilst running something

With your CPU not being stable anymore, it's probably deteriorated a bit, which happens over time anyway and overclocking speeds up the process. You either need more volts now or you need to lower your clock speed to 4.4 or maybe 4.3.

EDIT: I thought you were OP but it turns out you're not :lol:

Anyway you most likely need more volts, for 4.5ghz try around 1.33v - 1.35v.

The speedstep info still applies though.

so, small intro - once again today i got bored after checking my beard from the mirror and did restart for my PC to access the BIOS. i have 4 GHz 1.2v not finally tweaked 24/7 eco OC profile, a 4.5GHz 1.29v 24/7 Stonehenge-stable profile and then i had 5GHz 1.4v unstable bench profile.

so, i did mess around with the PLL voltage, with the Load-Line Calibration and some offset voltages and so far IntelBurnTest and Prime95 small FFT tortures are getting along that OC really well.

5GHz @ 1.4v is decent?

Copy the settings in my 2500k overclock signature and see where it gets you.

oh, I thought you guys do not tolerate many similar topics. alright then
