I ditched work a couple hours early today to catch the Fedex dude....ripped open the box and was horrified to see "ADA4400CDBOX" on the sticker...looked at the proc itself and sure enough they gave me an ADA when I specifically ordered an ADV. Well, even though I was disappointed I opened it up and popped it in anyway...during my careful Zalman STG-1 application and hsf installation I forgot to reset the cmos on my mobo (a no no ) but what do you know? Yes...it fired right up to 2.6 and is now running perfectly at about the same temps as my Opty 148. The ADA (110w) and ADV are the same price so unless someone can give me a compelling reason to return this for the 89w I think I'll just keep it.
