256KB std and max / at processor speed
Processor and L2 cache in Flip-Chip Pin Grid Array (FC-PGA2) / motherboard contains one Intel PGA423 socket (with
Pentium 4 and heat sink), four RIMM sockets, five PCI slots, one AGP slot, integrated ethernet, and 850 chip w/ heat sink
No SMP support

128MB std / 2GB max / dual RDRAM (Rambus) channels / 32 devices max each channel /
Two 4D 64MB PC600 RIMMs / non-parity / four 184-pin gold-plated RIMM sockets (two per channel) /
two RIMMs installed (one per channel) / CRIMMs in two sockets / supports PC600 or PC800 RIMMs (not PC700) /
mixing PC600 and PC800 RIMMs results in PC600 performance / all installed RIMMs must be installed in pairs across both
channels / supports optional ECC RIMMs (mixing non-parity and ECC RIMMs results in non-parity)
