Intel
®
Server Board S3420GP has the following limitations on RDIMM:
Note: Intel
®
Server Board S3420GPV has two DIMM slots per channel on board and totally four
DIMM slots which support maximum RDIMM size to 16GB (4x 4GB DIMMs) because of thermal
limitation without BMC control.
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 or 1333MHz RDIMMs run at 800MHz.
3.3 Intel
®
3420 Chipset 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 in Intel
®
Server Board
S3420GP is to manage the flow of information between its eleven interfaces:
