Sandy Bridge Overclocking - Why not use vcore on auto?

post #1 of 16
Thread Starter 
Hello,


I've been wondering:

With Sandy Bridge CPUs, most people only change the multiplier and vcore in order to achieve a pretty nice overclock (~4.5GHz).

Why not just change the multi and leave vcore on auto?

Isn't it just a habit from the other ways of overclocking?

By leaving the vcore on auto, we won't even need the offset feature that some boards do not have.


I tested this with my 2500K + MSI P67A-GD65, and the result was pretty good. It only went up to 1.31v.

I know it depends on CPU and such, but some people ought to try it.

This is just my personal experience.

Some people do use it. Nevertheless, testing your own settings usually result in better results. For example lower temps and the such, thus minimizing the degrading a CPU would have from intense overclocking.

Trying to get 4.8 stable on my 2500k, auto gives me a ridiculously high 1.48 vcore whereas I'm getting pretty close to stability around the 1.38 mark.

Morale of the story: In this game it's just better to manual tinker with your vcore, even if you're using offset voltage.

The auto gives you a safety margin. Manual allows you to use lower vcore settings which can be just as stable.

Because the motherboard is a little too generous when it comes to giving the voltage to a certain overclock, that's why manually setting a value is better and working your way up for stabilty ensure's the least amount of voltage is used for that overclock without increasing the heat and the votlage to more than required for a certain overclock.

While I pretty think along the same way as everyone above me my biggest gripe with auto settings have been random spikes, I hate them to the core and try to set as many options to manual that I can.

So are most people using offset mode? New to overclocking on Sandy Bridge. On AMD everything was set manually. Auto seems to be a much more common setting over in Intel land.

My 2500k is stable at 5ghz with 1.392v Load. I'm using offset now at +.005v... This gives me 1.392v-1.400v Load and 1.024v idle. That's only .005v away from "auto". I tried it on auto and load gives me 1.648v !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! NO GOOD!!!!!

Wait you mean 1.648v isn't good?

I lower mine to 4.0ghz with 1.170v and is stable with lower temps.
