Also, the server boards in Intel

®

 Server System SR1640TH have the following limitations on 

RDIMM; 

ƒ

 

No support for LV DIMMs 

ƒ

 

256Mb/512Mb technology, x4 and x16 DRAMs on RDIMM are NOT supported 

ƒ

 

All channels in a system will run at the fastest common frequency 

ƒ

 

No mixing of registered and unbuffered DIMMs 

Note: 1066MHz RDIMMs run at 800MHz. 

The Intel

®

 3420 Chipset component is the Platform Controller Hub (PCH). The PCH is 

designed for use with Intel

® 

processor in a UP server platform. The role of the PCH on the 

server board S3420TH is to manage the flow of information between its eleven interfaces: 

ƒ

 

DMI interface to Processor 

ƒ

 

PCI Express* Interface 

ƒ

 

PCI Interface 

ƒ

 

SATA Interface 

ƒ

 

USB Host Interface 

ƒ

 

SMBus Host Interface 

ƒ

 

SPI Interface 

ƒ

 

LPC interface to IBMC 

ƒ

 

JTAG interface 

ƒ

 

LAN interface 

ƒ

 

ACPI interface 

 

Intel

®

 3420 Chipset PCH provides extensive I/O support. 

There is no PCI-E extensive slot available on the server board S3420TH in Intel
