Right, but if you know that, then you also know it is (most probably) a different issue then from what we discuss here.

Well as far as I can tell, he was running his E6600 at a fairly high voltage, just like you were, and both of them eventually died.

Is that not a fair summary of what happened in both cases, or did I miss a critical post somewhere?

I have no problem being wrong, if so, let me know what I missed or misinterpreted.

Thanks

from the sounds of it, i believe that the quality of the power the chip is receiving may be deteriorating. Be that through low quality capacitors/board layout, or low quality power supply. Heat build up as well on the motherboard needs to be looked at, as well as on the cpu.

If you read http://forums.overclockers.com.au/sh...d.php?t=582349 you will find that it is a bit different. In my case I assume that the combination of many months of 24/7 high voltage use + the usage of a Peltier were the cause. The deterioration clearly started after the frequent change from subzero temps to high in the 60 temps. Other people suggested that condensation (which might have escaped my attention) plaid a role. I am still not sure what caused the strange behavior, but as it started after I started using a Peltier, I think that there is reason to believe that the later is the cause.

On the other hand, I have tried to kill a E6600 with high voltage/high temps, by disabling all protection function in the BIOS, put the voltage at 1.7, run the CPU without a heatsink, and re-started the system again and again immediately after emergency shutdown for hours. I could not kill it although the temperature was probably well above 100 C.

That's the reason why I believe, despite my experience, that the current C2D are quite resilient against high voltage and high temps.

just to add to that i turned of the water cooling and all it did was shut down, it took 7-8 restarts to get her up and running again but its sitting happy at 3.6ghz again

so its not the heat of a once only event that deteriorates them

so it seams it a combo of constant high temp and high volts

sounds pretty much like a mobo problem, I don't think this is related to the CPU. It could be even the PSU.

posible as i have just got hold of a new psu a silverstone strider st75f and am already able to oc the gfx just that 1 notch higher on the 8800 gts

i will swap out the old mans st65zf and see if that resolves his isues

edit
well just swaped out psu`s and no change so we can cross that one off the list

Not to sure if this belongs here, but Microsoft have a microcode reliability
update that covers some Intel core 2 Duo and core 2 Quad chips, including
E6600. This of course is if you are running MS os on your system.http://support.microsoft.com/?kbid=936357

That's what ya get for overclocking

It's anyway unethcial, considering that you try "extorting" performance you havn't paid for in the first place.

Radius22 · 26th June 2007, 6:19 PM

Yes. The DRM equivalent for CPU clock speed would be a great step forward.

Somethin' for nothin'. How dare they.

mAJORD · 26th June 2007, 7:00 PM

hehe, and how easy they could do it if they wanted.
+- 5% bus clock deviation = cpu shutdown. Ouch

icewind · 26th June 2007, 7:45 PM

the other guy would jump on it so quickly.

intel stops any overclocking.... 1000s run to AMD.

never going to happen.

It's illegal, and unethical! You extort performance your are either not capable, or even worse, not willing to pay for!! At least you should feel bad about it.
