AMD Athlon 64 3000+ 90nm

This is an AMD Athlon 64 3000+ with the serial number ADA3000DAA4BW and this most likely was used in an OEM / Prebuilt machine. This chip is significantly smaller in size than the Athlon 64 3200+ 130nm I opened previously. This appears to have been designed or manufactured in 2004 as indicated by some close ups of the writing in the bottom right revealed. This line of chips was released in 2005 which holds up with the date code on the chip. Interestingly the IHS says 2001 for some reason.

 

I prepared this chip very carefully with a razor blade and water. This chip cannot be prepared using acids or etching pastes since it uses SOI (Silicon On Insulator) technology.

 

AMD chips tend to crater when using a razor blade whereas Intel chips do not. I have since discovered the cratering happens mostly when removing the solder balls layer closest to PCB, visible here: flic.kr/p/2jaWU2i

 

This is one of many chips I purchased on ebay and I have already taken apart and prepared of few of the other ones.
