" Model numbers 3800+, 3500+, 3200+ and 3000+ in socket 939 only will be affected by the new revision change from E3 to E6.
The E6 revision is pin to pin compatible with the current E3 revision, and will function in existing platforms based on 939 pin AMD Athlon(tm) 64 processors, but a new BIOS will be required to recognize the new CPU ID (Current CPU ID will change from 00020FC0h to 00020FC2h).
This new revision is expected to start shipping from July 15th 2005 and the marking of the affected model numbers will change as shown below:
