Thanks. THe batch is Q746A535 . 1.225 VID. Not amazing but certainly not bad either!

I got the same Q746A535 batch as you, gurusan, but my VID is listed as 1.125v in CoreTemp, the same as my previous E8400 (I returned as it had stuck temp diodes).

I was surprised yours was at 1.225 VID coming from the same batch as mine? But RealTemp shows my VID as 1.225?? At stock my voltage reads as 1.128v in CPU-Z...but I forgot I had C1E enabled! When I disabled C1E at stock settings, sure enough my voltage was at 1.20v, which is more like 1.225v with VDrop. My Xeon 3110 clocks to the exact same 4620MHz maximum as my previous E8400 did with 1.125 VID, (with 1.60v cpu and 1.2v VTT in bios.)

You must be using the older version of Coretemp to view your VID. The latest version 0.99.1 detects it correctly.

A lot of users have been comparing VID numbers but some are quoting their minimum VID while others are quoting their maximum VID. Solution? RealTemp 2.70 which displays both values in the Settings window and the real time VID in the main window. You shouldn't have to play with your C1E settings either to see both of these numbers. I'm hoping users will start posting both values for some more accurate comparisons.

A quick way to change VID when using XP is to go into your Power Options and select Portable/Laptop. This should drop it down to the Minimum VID at idle and it should increase to Max VID at full load. On a laptop I've spotted 4 unique VID values during the transition from idle to full load.
