S UPER S ERVER 6011L Manual 1-3 Mainboard Features At the heart of the SuperServer 6011L lies the P3TDLR, a dual processor motherboard designed to provide maximum performance. Below are the main features of the P3TDLR. Chipset The P3TDLR is based on the ServerWorks ServerSet TM III LE chipset, which is a high-performance core logic chipset that consists of a North Bridge and a South Bridge. The North Bridge includes an integrated main memory subsystem and a dual channel PCI bus that bridges the processor bus to a 64-bit PCI bus and a 32-bit PCI bus. The North Bridge also packs and unpacks data for PCI accesses, which reserves more processor bandwidth for multiprocessor motherboards.
The South Bridge provides various integrated functions, including the PCI to ISA bridge and support for UDMA33, security (passwords and system pro- tection), Plug & Play, USBs, power management, interrupt controllers and the SMBus. Processors The P3TDLR supports single or dual Pentium ® III FCPGA 500 MHz-1.4+ GHz DP (dual processing) processors and single or dual low power Pentium ® III processors at front bus speeds of 133 and 100 MHz. Please refer to the support section of our web site for a complete listing of supported proces- sors: (http://www.supermicro.com/TechSupport.htm). Memory The P3TDLR has 4 DIMM slots that can support up to 4 GB of ECC registered PC133 or PC100 SDRAM.
Module sizes of 128MB, 256MB, 512MB and 1 GB may be used to populate the DIMM slots. The DIMM slots are situated at a 25 degree angle to create a low profile and to promote efficient airflow through the chassis. It is not recommended that system memory speeds be mixed -- doing so will result in the memory operating at the slower speed. 1-4
