so i bought this when it came it came in a retail box, but the MF number on the cpu says this. ada3500dik4bi, get what ims aying so i check on NEWEGG it shows the BIBOX as retail but the dik4bi as OEM, so did this site put a OEM CPU in a retail box and pretend its a retail, plus why dont the MF numbers match as indicated on teh site and on the cpu itself? help
