The box does tell you the series. Ask them if they will assure you get the one you want, or if the salesperson is willing to look thru the inventory for the right type. When I built my Quad 6600 a couple years ago, I needed the right stuff for OC work, and found that Amazon shipped only that type of chip.
When I got the chip for this build, I again found it online. I got it from Antares Digital - they sell only D0 stepping. Oh and by the way bulding a PC with this processor is a blast. They run ~VERY~ good.... !!
