SUPERSERVER 6012L-6 Manual
1-4
1-3 Mainboard Features
At the heart of the SuperServer 6012L-6 lies the P4DLR+, a dual Intel Xeon
processor motherboard designed to provide maximum performance. Below
are the main features of the P4DLR+.
Chipset
The P4DLR+ is based on the ServerWorks Grand Champion LE
TM
(GC-LE)
chipset, which is a high-performance workstation SystemSet core logic
chipset designed for dual-processor systems.
The GC-LE consists of a North Bridge, a South Bridge and an IO bridge.
The North Bridge interfaces directly to the processor bus and integrates the
functions of the main memory subsystem and the IMB bus interface unit.
The memory subsystem consists of an 8-DIMM configuration accessed over
a 144-bit memory bus, which provides a significant boost in performance.
The South Bridge provides various integrated functions, including the PCI to
ISA bridge and support for UDMA100, security (passwords and system
protection), Plug & Play, USBs, power management, interrupt controllers
and the SMBus.
The CIOBX2 is an integrated IO bridge that provides high-performance data
flow between the IMB interface and the dual peer PCI-X bus interfaces.
Processors
The P4DLR+ supports single or dual Intel Xeon 512K L2 cache processors
of up to 2.4+ GHz at 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/TechSupport.htm).
Memory
The P4DLR+ has 4 184-pin, 25 degree DIMM slots that can support up to 8
GB of registered ECC PC1600 (DDR-200) SDRAM. Module sizes of 128 MB,
256 MB, 512 MB, 1 GB and 2 GB may be used to populate the DIMM slots.
(PC2100 is also supported, but only at a speed of 200 MHz.) Memory of
different sizes and speeds should not be mixed.
