Celeron D Intel Celeron D Takes New G 1 Stepping

Desktop Intel® Celeron® processors in FC-LGA4 (socket-LGA775) package on 90
nm process will undergo the following changes to the G-1 core processor
stepping:

• The CPU ID will change from 0XF41 to 0XF49 (Updated Bios required)
• No impact anticipated to existing platforms 845, 865 and 852 & 9xx family
• New S-Specs for affected product line items
• No change to Electrical and Mechanical Specification
• Desktop G-1 Step processors will be Pb-Free Second Level Interconnect (SLI) /
RoHS compliant and the integrated heat spreader (IHS) will be marked per JESD97
guidelines with e4 designation
• Addition of 2 new EM64T instructions LAHF/SAHF
• G-1 is pin compatible with E-0. The thermal/mechanical specification is within
overall package height specification
• Intel anticipates no impact to current platforms designed to Intel guidelines
• Additional resistor added to the package
