Tried out 2206 on my G0 Q6600 but too bad, Vcore values remained exactly the same as 2205 previously, varying between 1.15V idle and 1.25V load. So it looks like they upped the Vcore for B steppings only. Or perhaps diff. P5W revisions play a part, mine is the earliest 1.85V revision.
Whatever you read is wrong. The bios reads the VID of the cpu under load and uses 1.1625v idle. These are the EIST values. P5WDH Bios revision never changes stock vcore. The cpu itself determines this via the VID, which can be read in coretemp or everest. And by the way, lower VID is generally better.
