SUPERSERVER 6012L-6 Manual

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 LETM (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.
