Also, the server boards in Intel
®
Server System SR1640TH have the following limitations on
RDIMM;
 No support for LV DIMMs
 256Mb/512Mb technology, x4 and x16 DRAMs on RDIMM are NOT supported
 All channels in a system will run at the fastest common frequency
 No mixing of registered and unbuffered DIMMs
Note: 1066MHz RDIMMs run at 800MHz.
2.4.4 Intel
®
3420 PCH
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:
 DMI interface to Processor
 PCI Express* Interface
 PCI Interface
 SATA Interface
 USB Host Interface
 SMBus Host Interface
 SPI Interface
 LPC interface to IBMC
 JTAG interface
 LAN interface
 ACPI interface
2.4.5 I/O Sub-system
Intel
®
3420 Chipset PCH provides extensive I/O support.
2.4.5.1 PCI Express Interface
There is no
PCI-E extensive slot available on the server board S3420TH in Intel
®
Server
System SR1640TH.
