I have an AMD 64 system, but with the older 754 pin layout, not the full 939 pin 64 bit system. Given this system doesn't have all the pins for full 64 bit access to the motherboard (is it only memory????), will I see a performance benefit if I migrate to the 64 bit version of Ubuntu? Or, is this chip a little crippled, and therefore 32 bit (which in theory has no inherent performance penalty in AMD's implementation), and 64 bit performance are roughly comparable in this system so there'd be no benefit in going to the 64 bit version? Maybe put another way, what is the performance difference in 64 bit mode compared to 32 bit, of the 754 pin and the 939 pin AMD Athlon64's for the same clock speed? I hope that makes sense. <TABLE CELLSPACING="0" CELLPADDING="0" WIDTH="100%"> <TR> <TD> Kind Regards Russell ================== www.windsorcycles.com.au sales@windsorcycles.com.au ph. 02 4577 3209 bikes.no-ip.info Linux user #369094 ================== </TD> </TR> </TABLE> </BODY> </HTML>
