SB & IB overclocking - there is no single 'stock' voltage

Thread Starter 
After fiddling from my old bloomfield and phenom 2 to a sandy bridge e chip, i came to a conclusion that the stock voltage value as i used to know is dead.

i7 920 and p2x4 940 has a single stock voltage. but with the new intel cpu, depending on the multiplier set, the new cpu/board will have different vid which in turns request a different voltage values.

so when somebody says they overclock their sandy/ivy at stock voltage, it is not a single voltage, but it is the voltage your cpu multiplier it is set as.

What do you guys think?

Correct. Stock voltage is what ever the system needs to be stable. I do not think there is really a set voltage for these chips. They are usually really close to the same.

I assume each chip is tested and set with the lowest voltage to keep it stable at stock clocks.

I have 2 gpu's that are the same way. one is stock at 1.013 and the other is 1.068. Both are the same card.

Actually when people say they overclocked on stock they may not be wrong or lying, sometimes the VID won't change until you go so far, say you will have a set VID for 38-42x then once you hit 43x the VID will change. Each chip will be different but in my experience each VID usually covers a certain range. So it is very possible for someone to hit 4ghz at stock.
