CPU
Supports single/dual Intel
®
FC-PGA Pentium
®
III 533MHz~1.4GHz with 100/133MHz FSB (Front
Side Bus) designed for Socket 370 technology. FSB133 MHz Coppermine and Tualatin CPU are
also supported up to 1.2GHz
Chipset
The Server Works CNB30LE chipset incorporated as a north bridge is in charge of the host bus
interface and memory bus control. The memory bus control supports two and four way interleaved
of PC-100 and PC-133 SDRAM registered ECC
DIMM up to 4GB. The north bridge provides one
32bit PCI bus running at 33MHz and another secondary PCI bus running at 33/66MHz.
Memory
The four DIMM sockets on board allow memory upgrade to a maximum of 4GB using four 1024MB
registered SDRAM (Synchronous DRAM) DIMMs. For data integrity, the default setting of the ECC
(Error-Correcting Code) function of the memory system in BIOS is enabled. The DX3R
Plus-U/DX3R-U supports both 100 and 133MHz registered SDRAM only, 66MHz SDRAM is not
supported.
