3570k OC

post #1 of 10
Thread Starter 
Hey guys,

I've had my 3570k for about 3 months now set to 4.0ghz and the voltage set to auto. It usually stays at 1.2 idle and then jumps around 1.29 sometimes under load. I've read a lot around on the forums about stable voltages at 4.0 and my 1.2 seems a little high. I don't want to ruin my cpu by pumping too much power through it.

My motherboard is the GA-Z77X-UD3H if it helps.

I'm just wondering what you guys out there have set for your vcore and your OC so I can get a good idea of what it should be?

Voltages differ for every chip, for instance mine needs more than most. That voltage is not going to hurt your chip. Mine's 1.216 for 3.9ghz under load. Thats the lowest i can get it too rolleyes.gif . If you want to lower it, lower it in small increments until its unstable(.01v), then start raising it back up(.005-.01v) while using a stressing program such as Intel Burn Test.

Your voltage is too high because you're using auto voltage. Overclock using manual voltage because auto usually adds at least 0.1V extra on top of what you need to be stable. Here's an amazing overclocking guide on how to overclock Ivy Bridge chips on the UD5H but the BIOS is the same as yours:

There is a video guide at the end if you'd prefer thumb.gif

as mentioned it varies from chip-to-chip but I have mine at 4.6ghz at 1.27v. Doesn't matter how much voltage I put into it I cannot go higher.
post #5 of 10
my chip is one of the worse and I need 1.272 - 1.288v @ 4.4GHz but only 1.182 - 1.192 for 4.2GHz...
I have tried three different mobos and they are all the same more or less, so it's got to be the chip..

When I try to set my vcore manually, it still runs at 1.2.. which is the default. I tried it at 1.5 and every time I check with Core Temp after rebooting the idle is 1.2009.

Am I missing something?

It doesn't seem to matter what I do. It won't go any lower than 1.2.

When I set the CPU minimum speed under power settings is the only time it will drop below 1.2
