RDIMM memory configuration rule To get the maximum memory size on RDIMM, refer to the following table: Max Memory Possible Single Rank RDIMM 1Gb DRAM Technology 6GB (6x 1GB DIMMs) 2Gb DRAM Technology 12GB (6x 2GB DIMMs) Dual Rank RDIMMs 12GB (6x 2GB DIMMs) 24GB (6x 4GB DIMMs) Quad Rank RDIMMs 16GB (4x 4GB DIMMs) 32GB (4x 8GB DIMMs) Table 8. RDIMM Maximum configuration 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:  DMI interface to Processor 24 Revision 2.4 Intel order number E65697-010
