What exactly is vid?

post #1 of 8
Thread Starter 
I have a Q6600 VID 1.3250. Its stable at 3.2Ghz with 1.3200 vcore. What does this mean?

The Vid is the preset default vcore the CPU will run at when set to auto. Intel claims this the the vcore needed to maintain the default clock speed. Many of the higher Vid CPUs dont OC as high as the lower Vids. But it also does not mean that you cant run them at a lower vcore. I have an E4300 with a 1.325 Vid running 3.0GHz with only 1.29v vcore (default is 1.8GHz).

I read this a while back...

It is said that a lower VID value will yield better overclocks, but nothing's been conclusively proven.

http://en.wikipedia.org/wiki/Voltage...cation_Digital

Quote:
Voltage Identification Digital or VID means that a voltage-producing unit produces a voltage as specified by a digital input. For example, a unit with 4-bit VID would output one of at most 16 distinct output voltages. These voltages are usually (but not always) evenly spaced within a given range. Some of the code words may be reserved for special functions such as shutting down the unit, hence a 4-bit VID unit may have fewer than 16 output voltage levels.

As of 2006 VID is still a relatively new technique, and mostly applied to power modules outputting between 1.5V and 3.5V. These are used to control the supply voltage of high-performance microprocessors, for example in order to reduce the power consumption during idle periods.
I wandered into this topic wondering what the letters stood for. Wiki to the rescue! Maybe someone else wondered, so I pasted it here.

I know what vid is, I just didnt understand why I can overclock with lower vcore than vid. thanks for the info everyone.

Well, my VID allows me to pull off 3.6 with about 1.3 vCore, whereas most people need 1.4+ for the same overclock. I can say that would be a "better overclock" in a sense.
