if you have 'pni' in /proc/cpuinfo you should add -msse3.
-fomit-frame-pointer is useless/not needed on amd64-.

Re: [gentoo-amd64] Re: 3200+ - X2 4000+
I found this helpful information:
If you have a newer Athlon64(Venice or San
Diego)/Athlon64-X2(Manchester or Toledo) (check for pni in cat
/proc/cpuinfo) you can also add -msse3 to your CFLAGS to enable SSE3
support. Any chip using the 90nm process except for the Winchester
class Athlon64 supports SSE3.
Also bear in mind that all Athlon64 X2 and Opteron 165, 170, 175, 180,
and 185 processors are dual-core CPUs so make sure that you use
MAKEOPTS=-j3 in your make.conf. This doesn't affect the code but
might reduce compile times.
All socket AM2 processors are SSE3 capable as well.

Hi, Regis Decamps schrieb: Fernando Boaglio a écrit : The AMD cooler is th same from both CPUs. I have upgraded from a 3000+ single core 1,8GHz to a X2 4800+ dual core 2*2,4GHz some time ago. I am not using the stock cooler, I have an Thermaltake cooler. But what I experienced was, that the 4800+ was running at exactly the same temperature as the 3000+ did, so a dualcore processor doesn't necessarily have to be warmer than a single core CPU. I guess, if the airflow your case is OK, you don't _have to_ change the cooler with the processor.
