Depends, 90% of the VID quiz is correct

the more VID the more Vcore to get it stable, but sometimes is not...

I had a Q6600 L723A VID = 1,2875 and requiered 1,475 vcorebios to 3,6ghz prime stable

Now I have a Q6600 L737B VID= 1,225 and can do stable:

vcorebios= 1,325 3,6ghz
vcorebios= 1,432 3,8ghz

and benched 4234 on air at 1,625 vcorebios
11,809s SPI 1MB
