Supermicro Dual Xeon Mobo

The dual Xeon motherboards are arriving in droves. Ok, maybe "droves," is a bit of an exaggeration, but this is the third dualie board we've seen this week. Supermicro says its P4DC6 motherboard's Intel 860 chipset will support dual Xeons up to and beyond 1.7GHz. The board's main memory consists of dual channel 600/800MHz RDRAM with a data bus bandwidth of up to 3.2GB/s in two banks. The P4DC6 supports one 4xAGP Pro, two 64-bit PCI (66MHz) cards, four 32-bit PCI (33MHz) cards, and has one CNR slot. Dual Ultra DMA Bus Masters with 100MB/s burst data transfer rate support UDMA Mode 5, PIO Mode 4, ATAPI, LS-120, and ATA Zip drives. The P4DC6 comes with onboard Adaptec 7899W (7902 upgradeable from manufacturer) and dual-channel Ultra160 (320 optional) SCSI. While the board doesn't support as much RAM as the two other boards we looked at this week, Ultra320 SCSI is a nice forward-looking addition. Complete specs can be found on Supermicro's site .
