At the heart of the SuperServer 8042-8/8042-6 lies the P4QH8/P4QH6, a quad
processor serverboard based on ServerWorks GC-HE chipset and designed to
provide maximum performance with the newest technology available. Below are
the main features of the P4QH8/P4QH6. (See Figure 1-1 for a block diagram of
the GC-HE chipset).
Processors
The P4QH8/P4QH6 supports up to four Intel Xeon processors MP of up to 2.86
GHz with a 400 MHz FSB. Please refer to the support section of our web site
for a complete listing of supported processors (http://www.supermicro.com/

Memory
The P4QH8/P4QH6 has an MEC card that plugs into a special slot on the
serverboard. This MEC card has 16 184-pin DIMM slots that can support up
to 32 GB of registered ECC DDR200 (PC1600) SDRAM. Module sizes of
128MB, 256MB, 512MB 1GB and 2GB may be used to populate the DIMM
slots. (DDR266 is also supported, but only at 200 MHz.)
Onboard SCSI
