Hi, I finally assembled an amd64 machines: ASUS K8V SE Deluxe motherboard, Athlon 64 3000+, IDE disk, 2x512MB PC3200 Kingston memory, SuSE 9.1 64 bit from DVD installed fine. After booting I installed all patches, reboot went fine. I bought a cheap PCI gigabit card (RTL-8169, 21 euros) for my other machine and was able to do 58 MB/s from the other machine to the amd64, and 37 MB/s from the amd64 (measured with netcat < /dev/zero). My switch is a cheap Netgear GS105 (75 euros) and I use cat 5E cables. Is there any tweaking I should try to improve performance (like frame size)? Not that I need it :). I did not try SATA, Firewire, USB, sound (yet). Is Cool&Quiet supposed to work with this mobo/processor/kernel? I activated the option in the BIOS, but looks like SuSE says it isn't supported. Laurent # powersave -c Speed stepping is not supported.
