B-2 To L-2 Stepping For 2MB Conroes
Intel® is initiating a B-2 to L-2 stepping conversion for Intel® Core?2 Duo processors E6300 & E6400 (Conroe) and Dual-Core Intel® Xeon® processors 3040 & 3050 (UP Xeon processors based on Conroe) where they will undergo the following changes:
? New S-Spec and MM numbers for the converting products
? CPUID will change from 6F6 to 6F2
? Extended HALT power specification will reduce from 22 Watts to 12 Watts
? Die size optimized for manufacturability
? Minor visible difference between the B-2 and L-2 packages; see below for a visual comparison
? L-2 package is pin compatible with B-2 package
