Is 1.425v too much for a 1.25v kentsfield q6600

Is 1.425v too much for a 1.25 kentsfield q6600ghz?, everything that i need for overclocking is locked in the bios. i have currently overclocked it through ntune to 2.645ghz by increasing the voltage to 1.337, i am able to reach 2.7 by increasing the voltage to 1.425, temps never go above 45c @ 1.337v under load is that OK, I've tried reaching 2.7ghz with 1.337v and the system locks up and freezes any advice?

How i gather it, temps are really only the main issue when it comes to overclocking, Vcore obviuosly increases the temps so you can in theory increase the the Vcore as much as you like as long as the temps are fine, 72c or under when running Orthos is acceptable for me, some like it lower but i tend to think that nothing i run such as games will stress it as much as Orthos does.

On my old E6600 I put 1.55 Vcore through it (bios) and it was rock solid for 3 months with temps reaching 60-62c under Orthos. I currently have a Q6600 G0 @ 3.6GHz 1.45 Vcore (bios) 8 hours Orthos stable.

No, after a certain treshold has been reached, no amount of cooling can stop the damage the upped vcore will cause for a given process (.13, .09 etc..), theres generally a certain voltage most peeps won't go over no matter how well cooled because of this.

Hmmm, true to a point. But be careful, you know what happens when you put too much volts through any electric circuit, it blows (equally, because of heat arguably) but the point is that you can't always tell that a particular component is being overloaded and is going to blow before it's too late, and also sometimes you can't tell from the outside if it's a complex/packaged device/circuit. E.g. for example the CPU might not be smoking yet, and the temp sensor might not have risen yet to what you think is excessive, but you might nevertheless already be in a position to overheat/blow a couple of transistors or sections of the CPU that's individually being overloaded and thus end up with a damaged CPU...

I'm suprised you needed to change the voltage at all? Normally stock voltage on the Q6600 should get to around 3ghz.

@ Byte, Doesn't something in the BIOS [can't think of the word] close the PC when it reaches dangerous temps?

Yeah i didn't quite mean you can actually put some ridiculous Vcore of of 1.9 or something, more that his only at 1.425 and was basically saying his got nothing to worry about Vcore wise as he can still notch it up a fair bit safely.

Higher you run the vcore faster it degrades the chip aswell...although that isnt such an issue as they still tend to last years even when overclocked.

its a dell 720, they have locked oc in the bios, but through ntune i went from 10854 to 11921 3d mark 06 btw will 1.425v be ok?

 

[Darkman]

Misread the OP. Sorry.

 

[sammie377]

Should be fine, I've put 1.7v through mine for quick benchies.

 

[psychas]

ortos stresses only 2 CORES YOU fssssss....

 

[young]

i use 1.4875, i think you will come under problems with temperatures before you end up going to high voltages, im at 3.6, and my temps are too high for me to try anything higher. I wouldnt worry at all!

Buy a new Mobo and clock its pants off, 3ghz on stock volts is easily achievable.
