January 11, 201610 yr Thanks, this chip is strong indeed - 475fsb @box cooler without mount. Binned it through 25pcs.
January 11, 201610 yr Didn't test it higher than 505Mhz yesterday. I think wall should be at 510-513mhz - was not able to run it @510mhz yestreday but I voltages were not maxed out yet. 476mhz air limit.
January 12, 201610 yr From my experience batch means nothing. 40MHz FSB wall difference within two cpu with next serials (same batch and pcb code).
January 12, 201610 yr I agree batch means almost nothing - had a chance of binning e6750 50pcs same batch - the difference was 65-70mhz fsb between worst and best with best one 20mhz above average.
January 12, 201610 yr I tested ~50-52 x celeron 430 and there was 16 different batches. All of them Costa Rica, 2007(24pcs) and 2008(23pcs), few from Malay. The same batches were close to another from the same batch (eg. 20 MHz FSB from the best to the worst from same batch code). In dual core and newer than 65 nm batches are less informing. Atleast country and the year is often crucial. Edited January 13, 201610 yr by ludek
