I heard that Intel E5200 2.5ghz that has R0 (SLB9T) stepping is better in oc than the M0 (SLAY7) stepping, is it true?what's the difference between those two?
Intel's Pentium Dual-Core E5200 processor is getting on course for a specifications update. The chip will feature in a new, improved Wolfdale-2M core, spec'd out as the R0 stepping, from its current M0 stepping. The new stepping is intended to add new instructions, power-management features, and bring about changes in the chip-package. A short list of known changes is as follows:

CPUID changed from 10677 to 1067A
Power State Indicator (PSI) support with Intel 4 series chipsets
New instructions - XSAVE and XRSTOR
New S-spec and MM numbers
New halide-free chip package
Due to the changed CPUID, users may require BIOS updates to detect the CPU.
