I swapped my processor for a Q9650 3.0Ghz, someone wants to buy the Q6600 that came with my 420 but want to know the stepping. How can I find out for them?
I've never seen CPU stepping listed by Dell.
Look at the top of the chip. If the writing includes the phrase SLACR it is G0 based; SL9UM, B3.
Happy to help.
It is a G0, right? G0 is better for over clocking.
BTW, many believe that the lower the VID the better the chip is for over clocking. You can find VID with core temp, for example.
VID is the stock vCore for the chip. It varies for each chip and is determined by Intel as part of its testing. When the MoBo is set to auto for vCore, this value tells the MoBo what voltage to use to get the chip to "start up".
