That's the reason why when I build, I don't build with the latest and greatest CPU, video card and other hardware. New stuff has always had lagging support in Linux. When something new comes out, Microsoft is in on the details early, likely because they pay a huge sum of money for the info. So, when some new piece of hardware comes out, they get it first. In Linux, I've read that some things have to be reverse engineered which is time consuming. Think about document scanners and printers. Some scanners and printers are still not supported and a lot only have limited support. Some of those have been out for years. I'm not to surprised that you have ran into this. Since I built a rig that technology wise was already a year or two old, everything worked out of the box for me. CPU temps and all. Mine seems to recognize my cores properly, as best I can tell anyway. Gkrellm isn't complaining and neither is htop. The one thing that freaked me out, CPU temps. They have a new and improved sensor that reads from the silicone wafer itself, deep inside it seems. It responds faster and is likely more accurate but it is much higher temps than the old temp that was of the die, right under where the CPU cooler sits it seems. When I first saw 190F temps, I kinda freaked out a bit. I thought I was trying to cook a egg with my CPU. I was checking that the fans were running and all that. I think it was Rich that posted a explanation. As I said, the temp is likely more accurate but still, I was not expecting that. When I build a new rig several years from now, I might build a AM5 that is either available now or will be shortly. Even my first rig was built with things that had been released for close to a year. It was still plenty fast for the time tho. I even named it Smoker. My next rig was named Fireball. I couldn't think of a good name for this rig that would line up with those two names so I went with Gentoo-1. I guess next rig will be Gentoo-2. ;-) It is sometimes hard to tell if everything is supported. Linux is a great community but someone has to be the first to buy something and see if things work. Once bought, you kinda stuck with it. It takes a while. Then you have to figure out which forum or other website where a person is describing what works and what doesn't. Then how dated that info is. I find that usually after a year, it is likely supported as far as CPU, mobo and such. Other stuff like printers may take longer. It is a problem tho. It's almost like a leap of faith when buying newly released hardware. Rant on. This may help the OP too. It may be a good idea to mention that some things might not be well supported yet. Dale :-) :-)
