4.8GHz Safe?

[TheNinjaNextDor]

I have my 3770K at 4.5Ghz and a Vcore that hovers around 1.35-1.4 (god damn) according to CPUZ while running Prime95. During the test I get to the high 60C-with low 80C spikes.

I've tried setting my vcore to sit at 1.3 and my system crashed, so I keep it on auto which starts at 1.215 and goes up to 1.8.

 

Should I change that 1.8 to 1.4 or 1.5?

Is it safe to go for 4.8?

What would you do first?

 

I can post a picture of my Vcore and frequency settings if necessary.

Thanks!

 

Edit: THERE IS A GRINDING NOISE ON STARTUP? I DONT WANT 4.8 I JUST WANT 4.5 AND NO GRINDING. ANYONE KNOW?

If you need the performance, why not I usually oc it a little bit but only go high when I'm working or doing insane renders

[Excon]

That is incredibly difficult to follow.

Sorry, I edited the format to make the question more visible. Tell me if I need to do more.

Err.. Wouldn't you set it at 4.5 and keep going up until it gets unstable then increase the voltage? You want the lowest voltage that keeps the system stable with no BSODs or anything like that.

[Excon]

Wait it was spiking up well past 1.5? That is not good....

I just want to know if the temps are safe and if I should mess with a lower voltage before hand.

[acidydragon]

Don't leave it on Auto. Set a number, or it can crank it too high.

[MrImnotMLG]

I'd say stay where you are.

[TheNinjaNextDor]

It was hovering at around 1.35-1.45V.

1.8

wait, is that volts?

1.8 volts?

[TheNinjaNextDor]

What should I set it to?

There are 3 boxes. One is for the auto of 1.215, the other for 1.3V, and the last for 1.8.

[TheNinjaNextDor]

wait, is that volts?

1.8 volts?

Yeah.

That is the PLL.

[dragosudeki]

The temperatures don't matter unless your past 85 (in my opinion) though the voltage is treading dangerous grounds....

[helping]

Yeah.

That is apparently the max. (wow)

I'd need a new pair of pants if I saw my chip hitting 1.8v every now and then

take that auto voltage off and manually set your LLC to hit 1.45v under load.

[Lord Pantaloons]

anything past 1.4v will degrade your CPU

Done.

What should the vtt be set to?

And IMC?

[MG2R]

I think I have read a max Vcc of 1.65V in the Intel spec sheets once, so I REALLY wouldn't go above 1.55V. Could be mistaken, though.

 

IMHO, as long as your temps are in check and your voltage never goes above 1.45V continuously, it's fine.

[MG2R]

anything past 1.4v will degrade your CPU

Any voltage will degrade the CP.

[Lord Pantaloons]

Any voltage will degrade the CP.

1.4 will do it faster

[MG2R]

1.4 will do it faster

And 1.3 will do it faster than stock as well, I don't really see where you get the 1.4V treshold for where degradation begins

[TheNinjaNextDor]

Here goes 4.8...

[Lord Pantaloons]

And 1.3 will do it faster than stock as well, I don't really see where you get the 1.4V treshold for where degradation begins

I wasn't saying that 1.4v is the degradation threshold. To my knowledge 1.4v on modern intel chips is where the rate of degradation increases drastically or at least that's what seems to be the common consensus.

Ok. 4.8 and a system service exception?
