The Official OC (OverClocking) Thread!

The Zelmans secured to the motherboard Via a backplate as you probably already know, everything was well secure last I looked, I would say I applied the thermo paste (my first time) thinly, less than paper thin with a credit card.

Thanks for the advice on the posting.

 

Temps in my room are not that great, we have the heating up fairly high, will that effect the temperatures aswell?

 

It will, but it stands to reason that I used to run a cooler of similar performance on a CPU that puts out more heat, in a room of temperatures 30C or higher, and I reduced the fan speed, and at load playing games, I never used to exceed 54C.

 

Are you using the white zalman thermal paste? as ive found this a let down.

 

Yes I am indeed using the Zelman paste that came with the cooler, does the paste really make that much of a difference?, my last stock intel cooler had high temperatures too about 10c more that what they are now!.

Is it better to paste the thermo on or just put a blob on the top of the CPU and place the cooler on top?

If the thermo paste is not the problem, what could be causing the high temps??

Thanx for all your replies by the way..

 

A small blob usually does the trick, but you'll need to thoroughly clean off the existing stuff first.

 

Better to use artic silver than the zalman stuff, dropped my temps buy 5ºc overall, the zalman stuff is ment to be spread onto the heatspreader of the cpu, I dont think it will spread like artic silver when applied to the centre of the heatspreader.

 

Wheres the heatspreader?, sorry its the noobie coming out in me again!lol

 

the processor top, its not actualy the processor you see, its the heatspreader.

 

Yeah, thats what it says in the instructions, spread it on thin. So what else could be causing these temperatures?

 

Not having enough airflow through your case, having the back of your case too close to a wall as this causes back pressure making your system have to work harder to push the heat out.

running your zalman too slow, try adjusting it upto around 2300 rpm, youll get a little noise increase, but its finding the sweet spot with them, I use speedfan to control mine, and have it running between 40% - 70% speed, I only turn it up full for video encoding.

 

Looking at your case Air flow shouldnt be an problem.

 

Ive actually got the 3D Aurora with the clear plastic side (No vents), I just took the side of the case off and uplugged the Zalman Fan controller and just plugged the zalman in direct. The temps now are as follows:

Sytem temp: 51c
CPU Temp:47c

Whats the best way to test the temperature under load?

 

download orthos - http://www.techpowerup.com/downloads/385/



and coretemp - http://www.thecoolest.zerobrains.com/CoreTemp/

 

Thanks CK5134 for the links, heres a thought, my machines up on a table at waiste level, does it matter?, cos the air I would say is colder down below is it not?

 

My rev number is located right around where the northbridge is. I think CPU-Z can also tell you the revision, but I'll make sure when I get home.

 

true it could make some differance but if you have it too low it can cause dust problems, if in doubt give it a try at a lower level, to be honest I would only expect a 1-2ºc drop if it makes any differance.

Have you tried lowering the v core slightly? as any reduction you can make and still have a stable clock will help the heat issue.

would be worth moving to artic silver 5 as your thermal paste although that will only gain you a few degrees too.

 

Ok got Orthos, how do I run a stress test on it?, I just tried pressing start and it came up with:

Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.
FATAL ERROR: Rounding was 0.4991455078, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 0 minutes 3 seconds - 1 errors, 0 warnings.
Execution halted.

 

Ah your overclock isnt stable then, I would definatley say that its the heat issue thats causing it, You cant give your processor any more power as that will just increase the heat.

 

Hi Sheeny,

Also

If Orthos is crashing in 3 seconds then it's because you don't have enough voltage for your overclock.

To get my E6700 to run Orthos at 333 fsb, I have 1.4250 Vcore. Everest reports this setting as 1.37 volts.
This is an Asus P5W-DH motherboard and the same cooler you are using.
If you don't want to run the Vcore that high then you will have to reduce the FSB frequency. My CPU temp at full load is ~47C, Core temps are ~44C.
That Aurora case should have come with a mesh side panel (mine did). I'd use that if case cooling is an issue.
When I apply the thermal paste I follow the instructions at the AS website:
