B2 vs L2 stepping E6300,E6400

[Diagrafeas]

Does anyone know what is the difference between B2 and L2 stepping E6300,E6400 processors? Which one overclocks better? What is the best overclock you have reached and at what voltage?

L2 - is the proper Allendale core with native 2MB L2 cache.

B2 - is a Conroe core with half the 4MB L2 cache disabled.

If memory serves me right, I think I saw somewhere where the B2's (conreo core) were the better overclockers.

how do u tell what stepping yours is?

Either CPU-z, or look on the underside of the CPU for its PCB code (printed in gold next to the IC's in the centre).

001 - Conroe
002 ? Allendale

thanks.

me happy with b2 then. mine does 3.2ghz orthos stable at 1.337v in bios. under load it dips to 1.28v. i can dig b2 🙂

L2 has max VID of 1.325 while B2 is 1.3525

Seems like the lower voltage L2 would be better?

The L2 stepping could well be better. I personally haven't seen much info on the net though (not that I?ve really looked).

It would be interesting to know though.
