SUPERSERVER 6022C User's Manual 1-3 Mainboard Features At the heart of the SuperServer 6022C lies the P4DC6+, a dual processor motherboard designed to provide maximum performance. Below are the main features of the P4DC6+. Chipset The P4DC6+ is based on the Intel 860 chipset, which is a high-performance core logic chipset that consists of three major components: the Memory Controller Hub (MCH), the P64H and the I/O Controller Hub 2 (ICH2). The MCH is optimized to provide superior performance between single or dual Xeon CPUs and the dual channel RDRAM memory, which operates at up to 3.2 GB/s data bus bandwidth.
The P64H provides support for two PCI-64 slots and two SCSI hard disk drive channels. It interfaces directly with the MCH. The ICH2 is a highly integrated multifunctional I/O Controller Hub that pro- vides the interface to the PCI Bus and integrates many of the functions needed in today’s server platforms. Processors The P4DC6+ supports single or dual Xeon Foster 1.5-2.4+ GHz processors at a 400 MHz front side bus speed. Please refer to the support section of our web site for a complete listing of supported processors (http:// www.supermicro.com/TechSupport.htm). Memory The P4DC6+ has 4 (four) 184-pin RIMM slots that can support up to 2 GB of 600 or 800 MHz RDRAM.
Module sizes of 64 MB, 128 MB, 256 MB and 512 MB may be used to populate the RIMM slots. Onboard SCSI Onboard SCSI is provided with an Adaptec AIC-7899W SCSI controller chip, which supports dual channel, Ultra160 SCSI at a burst throughput rate of 160 MB/sec. 1-4
