Confused about voltage still :(

post #1 of 33
Thread Starter 
Ive been talking with an Intel technical support lad, and they have been telling me that when the cpu voltage is set to "Auto" can change the voltage between 0.85 - 1.5 volts.

Ive been asking them, would it be safe if I could set the voltage to 1.45 and it wouldn't do any sort of damage to the cpu.

The message I received back

Quote:
I am afraid that this is not actually the way it is meant to work. The processor is designed to work idle between 0.85 to 1.5 volts. In the case you manually moved the setting from “Auto” to some fixed value, there could be the eventuality in which the processor needs to go higher on voltage, speed and/or multiplier, due to a requirement from either the chipset or the BIOS itself (When a set of instructions is coming through the processor the MCH (Memory Controller Hub) of the motherboard would assign the instruction to a particular core, making the system run different tasks at the same time putting different load on the processor cores) which could end up on sending the processor to either more higher or more lower values than what I has been designed for. This could harm the motherboard, the memory or even the processor.
So what has it been summed out to?

At Auto it can change its voltage between 0.85 - 1.5 volts so it MUST not do much harm to the processor if you set the voltage in that range (0.85 - 1.5) in bios?

Thanks

1.5v is going to do harm most likely, 1.45v will probably lower your processors lifetime but unless your keeping this processor for 5+ years I wouldn't worry to much.

Personally, I don't like going above 1.4v after the vdrop. (Usually about 1.43-1.45v in bios)


Also, I wouldn't talk to the actual company about overclocking cause theyll likely kill any RMA support you have if you do. On top of that, they usually know nothing about it.

Sounds like they are trying to justify not telling you to run it at 1.45v. Voltages fluctuate depending on load and idle anyway. I would set the voltage to as low as is stable with the clock speeds you choose to run.

Well, to be honest I don't know much about this but if logic works correctly I would expect that when the bios has been switched form "auto" to a fixed voltage then the features of the mobo that allow a fluctuation depending on system requests is disabled and therefore cannot alter the voltage. Think of it like cutting the throttle cable off your gas pedal on your car and clamping the throttle at a specific location...no matter how much you push on the pedal the throttle won't change. That is at least my guess as to what should happen.

Depends on the board. With Intel's SpeedStep, voltage automatically changes when dropping the multi. However, some older motherboards don't support this feature.

I should be keeping this E6600 for about half an year to a year MAX. Matters when I get a job .
So if 3.4GHz required 1.425 volts for example, that should be safe?

The E6600 is a strange CPU, it can take a crap load of voltage.
