Made this thread in the wrong forum moved it here :p  !!!



Hello overclock wizards and tech nerds !!!
Long time reader 1st time poster presenting a problem (or not)

Let me kick off with this, ive checked hours upon hours upon hours of forums posts / google checks / guide's / benchmarks how to overclock my 2500K sandy bridge

My system specs:

MoBo - MSI P67A-GD65
CPU - 2500K sandy Bridge
CPU Cooler - Cooler Master 612S
PSU - Coolermaster 500W
Memory - 2x4gb Corsair Vengeance
GPU - Asus Radeon 4850 1gb
HD - Sata 7200rpm hardisks x3


Alright now my problem:

I followed the excelent guide's here on Toms hardware to overclock to 5000ghz.
It worked but i cannot believe the temps i am getting.
After several stresstests these are the results

Prime95 4 hours torture - temp not getting higher then 62 degrees at 5000ghz
Intel burn tests x10 - 65 degrees
Intel cpu strestest - 62 degrees

The voltage i have setup is 1.4 voltage
These are my temps idle / load
Tempreture software used are:

Speedfan 4.41
GWInfo64
Aida64 extreme edition


HWINFO64 Sensor Status
Idle at 4500 / 5101.3ghz -
Core#0 - 43 degrees low - 48 degrees highest at idle
Core#1 - 34 degrees low - 44 degrees highest at idle
Core#2 - 36 degrees low - 47 degrees highest at idle
Core#max - 44 degrees low - 54 degrees highest at idle

Speedfan - these always shows me to lowest temps out of all temp sofware used any reason why that could be ?

Speedfan temps:
Temp1 - 45C
temp2 - 42C
Temp3 - 30C
Core 0 - 31C
Core 1- 29C
Core2 - 31C


I realy want to know if this can be right.
after reading many many guides people use watercooling systems from 200/300 dollars to achieve high clocks.

I just have a simple Coolermaster 612S that dint even scored better then some of his own price range.

Do you guys think its safe to run the system at these clocks with these temps or do you guys think sensors are flat out broken ?

Iam kinda new to overclocking and do not want to damage components of my pc.

Many thanks in advance !

all i can say is u must have hit gold on ur cpu chip..
October 31, 2012 9:20:54 AM

Hit gold as in lucky with the chip i purchased with this performance ?
If you look at all the temps do you find any strange values ?

Iam realy affraid to blow up my cpu but still i clocked bit by bit by bit and it only stopped booting up at 52x multi at 1.4 volts.
As i only have a 4 year old PSU Cooler Master 500W...

I am way to inexpirienced to feel confident that these values might be true and thats why i want better vieuw from you people to look and spot something that might not be right / ok with these clocks.

hit gold for both really.... i have seen others get 5ghz on air in the past but then ive never overclocked a i5/i7 (intel) before always been a amd person. your temps seem fine and your only at 1.4 volts which is good as well. would have thought your psu is a bit low but then like i say might be different for a intel setup.... if you are unsure about this overclock then i would maybe down clock a little to 4.8 just to be on the safe side..
October 31, 2012 10:08:55 AM

Yes my PSU is old it feeded my previous I7920 for more then 3 years and it still serve's me well :) 
I am taking your advise and clock back to 4.8ghz to be more safe.
Still dont thrust those temps specialy the diffrence between idle temps from Speedfan and Aida.

Is there any1 out there who have a similar setup and achieved stable clocks on air cooling with these clocks / voltage ? :)

My only real concern would be would you want to run at 5 ghz stable all the time. I would maybe push to 5 when you can for benchmarks then go to something less extreme maybe 4.2-4.5. Just considering the lifespan of your cpu in all of this.
October 31, 2012 10:39:16 AM

Yes clocking back to 4500ghz / 4800 Turbo :) 

Still find it strange that my temps would just not go beyond 68 degrees with all these cpu stress tests with a simple cooler master 612S.
I realy tought something was not monitoring my temps right with these tests.
Was already thinking my good old PSU of 500W was messed up, but i figured temps are monitored from the MoBo :) 

Also can you clear up why Speedfan is showing me much lower temp values then all the other temp software ?

For some unknown reason i cannot install CPUID / CPU-Z :( 
ive tried uninstalling that program 4 times and rebooted etc etc but it keeps giving me an error.

Downloading Coretemp now ! :)

Yea that's quite odd I don't know =\ I suggested gpu-z so you could see your gpu temps

My Asus HD radeon old timer 4850 oc to 680 (625 standard clock) is heating up to 80 degrees in full load.
I wanted to buy the 670 or 7970 but decided to wait it out untill Ati comes out with the 8xxx series.

GPU-Z is installed, but CPU-Z is refusing my pc :(

That sounds pretty high for a video card temp. But I'm not exactly sure what the thermal threshold is for the 4850.
November 1, 2012 8:49:08 AM

Yes i know i can get it to 60/70 degrees in load, but its a ati card and its been running for around 3.5 years.
This card is known for its high temps :) 
So far it never failed me :)

Do you perhaps live in Canada and overclocking during the winter with your window open?
November 8, 2012 9:58:46 AM

Ive overclocked to 5.2ghz on air and let me tell you. Youve hit gold here. 84C are my temps with 1.52 volts. Cant believe your temps and such low voltage your using.
