I bought my AMD64 system in early May. It has a 3200+ processor on a Gigabyte K8N Pro MB with 1 GB of DDR 400 RAM. For over two months I've been running SuSE 9.1 in 64 bit mode with no problems. Suddenly a week or so ago I encountered system freeze ups to the point where I couldn't even run Knoppix anymore. Long story short, the repair guy at the local shop I bought the box at said that on AMD64 systems, the DDR 400 memory needs to be underclocked down to DDR 333. "Why would it work for two months with no problem?" said I. "That's the way they are." said he. Does this sound right? Does anyone here have DDR 400 RAM on their boxes that work properly? I haven't even gone into how they snookered me out of $100 for a new hard drive when we thought the freeze ups were related to hard drive access. So you can see the reason I'm a little sceptical. It just doesn't sound right that you can't run DDR 400 on 64 bit, but who knows? (Hopefully someone here, which is why I'm asking... :-) -- Bryce Hardy (Santa Rosa, CA USA) cygnia@sonic.net
