Not all memory chips are compatible with all motherboards. Each motherboard requires memory of a particular type, speed and interface. Even if the memory fits into the board, the motherboard may not be able to process the memory chip. The MSI K9N Platinum does not support DDR400 memory, as the memory is not compatible with the requirements of the board.
Compatibility
The MSI K9N Platinum supports dual double data rate II synchronous dynamic random access memory -- (DDR2 SDRAM). DDR2 SDRAM transfers data at a rate twice as fast as its predecessor, DDR SDRAM, but at half the speed of its successor, DDR3 SDRAM. DDR RAM is not compatible with DDR2, so the MSI K9N Platinum cannot use DDR400 memory.
Requirements
The DDR400, also known as PC-3200, transfers data at a peak rate of 3200 MB/s, and does 400 million data transfers a second. The MSI K9N Platinum supports DDR2-533, DDR2-667 and DDR2-800 RAM. Memory installed to the MSI K9N Platinum can transfer data at a peak rate of 6400 MB/s -- twice the rate of the DDR-400 -- and can perform up to 800 million data transfers a second.
Specifications
The MSI K9N Platinum provides four total slots to install DDR2 RAM. The motherboard requires 240-pin, dual in-line memory modules (DIMMs). The board cannot process DIMMs of another pin specification. The motherboard supports up to 8 GB of memory.
Basics
Random access memory (RAM) is a form of volatile memory. The computer temporarily stores data to the RAM for processing. The computer cannot access data or run applications without first moving the information to the memory. The RAM loses all of the data stored to it when the computer is powered off.
