Pete, Since 32 bit apps can not work with more than 4GB (per CPU (2GB is more likely for most OS)), only SMP would really see a need for more than 4 DIMMs. A single 32 bit app can address only 4 Gigs in a single segment, but more using the segment-offset scheme (we all hated in the past). An OS can address more than 4 GB. Windows 2000 - Advanced Server can address 8 GB, Datacenter version can address 64 GB. I don't know about Athlon, but I believe Xeon already has at least 36 bit addressing. I think where you could use the huge address space is databases. A lot of memory can enhance the performance greatly. A NUMA machine with higher latencies would be faster than disk access, but ideally, the memory should reside on the single machine / node. Joe
