Folks, First of all, I always appreciate reading the comments and replies to the questions. They are very useful. Recently there was a thread about a AMD64 setup but there was no clear mention of specific mobos that Simply Works. So I'd like to have recommendations from folks who actually are running successfully an AMD dual-core processor. I presently have a MSI K8N Neo4 SLI mobo and it's certainly not working well. I sent it also to California during the MSI recall for the dual-core update. Didn't change much: - USB does not work - Audio is only stereo (although it annouces 7.1 - not very encouraging) - SuSE 10.0 (and 9.3) gets confused about the two ethernet ports I have to fix them manually. - SATA Raid support is software-based (even though it has two different HW interfaces) - Audacity sometimes says it can't play any audio (could be an OS thing) Firewire works, as well as everything else ;-) So I use it, and I like the speed, especially with the 4 GB of RAM. I have a Zalman fan, and, very quiet power supply, amd quiet case fans, so it's not too bad. But I would like to get a mobo with which everything works and on which it is possible to expand (eg. adding a M Audio card for instance) with problems. Hardware SATA raid would be a plus, but I can live with SW raid. Anyone out there effectively using an AMD dual-core CPU with a 64-bit mainboard for MIDI sequencing and audio recording purposes without having to fiddle around a good percentage of the time ? If so, I'd like to get the exact mobo description and I'll do everything to get one exactly like that. Please also tell which distro is used. Thanks ! Al
