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
