The "L" in the code stands for 1.5V default voltage. No TBredB has a default voltage of 1.5V; the lowest default voltage is 1.6V. An 1800+ TBredB would have a code of AXDA1800DUT3C. </font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif"> </font><blockquote><font size="1" face="Verdana, Helvetica, sans-serif">Zitat:</font><hr /><font size="2" face="Verdana, Helvetica, sans-serif"> The reason is subtle, though. All TBredA stepping codes end in the letter "A." All TBredB stepping codes end in the letter "B."
Yes, there is a TBredB with a stepping code of AIUGB. The "B" is what counts here, not the "AIUG" part. Yes, AMD is overlapping codes, which makes it harder to identify an "A" from a "B." Such is life. </font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Außerdem hat der A CpuID 680, B 681!!
