Dogs, don't be fooled by that tiny different thing, you are a very good and fair overclocker I know of!!:)
ok, here is the scoop:D
I decide enclose the heatspreader but not stick on them because I strongly believe that's just a joke if you think HS will help you to get you extra FSB on that. agree?
second, the date code on the sticker doesn't mean when the date the IC was produced. It merely means when TeamGroup record it as ship out date.
Now the new batch BH-5 IC in TeamGroup are all from same date produced from Winbond.
